Taking a 37kW RAETTS blower as an example, under reasonable working conditions, it can replace three traditional 22kw RAETTS blowers. It can save about 190,000 kilowatt hours of electricity a year, which is equivalent to about 115,000 yuan in electricity bills and about 23.4 tons of coal. , reducing carbon emissions by approximately 172.6 tons.
As a basic and key industry for economic and social development, the water pollution control industry is one of the key areas to implement the goal of “carbon peaking and carbon neutrality”. RAETTS blower provides a feasible path for energy saving and cost reduction in the sewage treatment industry with practical intelligent blower equipment.
6. Energy-saving technical reforms in the cement industry focus on energy saving at the source.
The National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Ecology and Environment, and the National Energy Administration recently jointly issued a notice (hereinafter referred to as the “Guidelines”) “Implementation Guidelines for Energy Saving and Carbon Reduction Upgrading in Key Areas of High Energy-Consumption Industries (2022 Edition)”. The “Guide” puts forward clear requirements for the scientific transformation and upgrading of energy-saving and carbon-reducing technologies in key areas. It proposes energy-saving and carbon-reducing transformation and upgrading plans for 17 key industries, including the cement industry, to effectively improve the energy efficiency level of key areas and reduce carbon emissions. Emission intensity plays an important guiding role in accelerating the realization of green, low-carbon and high-quality development.
In 2020, my country’s cement industry’s carbon emissions accounted for approximately 13.5% of the country’s total, ranking second only to steel among industrial industries. From the production process, it mainly includes raw material paper cups, clinker calcination and cement production. A large amount of energy is consumed in the production process. The energy consumption cost of some industry leading companies accounts for more than 50% of the production cost. Promoting industrial structural adjustment in the cement industry is the key to high-quality development and an important measure to achieve “carbon peak” and energy conservation and carbon reduction. In the dual-carbon era, the energy-saving and carbon-reducing transformation and upgrading of the cement industry has entered a critical period, and the cement industry has a strong desire for energy-saving and technological transformation. Source energy saving in the cement industry generally refers to saving coal and increasing the replacement ratio of raw fuels and waste. In fact, the selection of blower, a key link in energy consumption, is also an important part of energy saving and consumption reduction.
The use of new air suspension and magnetic suspension centrifugal blower can save energy and reduce consumption, with an energy saving rate of more than 30%. RAETTS blowers have provided world-leading blowers that save energy and reduce consumption for many cement companies across the country.
RAETTS air suspension blower are based on the general trend of “carbon emission reduction” in the industry, relying on the world’s advanced fluid dynamics technology, craftsmanship and the world’s advanced design concepts, integrating air suspension bearing technology, ultra-efficient permanent magnet synchronous motors, and aviation aluminum alloys The five core technologies, including the impeller, the world’s original motor cooling technology, and two-stage air compression technology, have created a new era of blower products with ultra-high efficiency, low noise, and low energy consumption, and are known as the “preferred energy-saving device in the cement industry.”
7. The world’s advanced blower enable the cement industry to save more than 38% of energy.
The “Action Plan for Strict Energy Efficiency Constraints in Key Industries of Metallurgy and Building Materials to Promote Energy Conservation and Carbon Reduction (2021-2025)” jointly formulated by the National Development and Reform Commission and other five departments requires that by 2025, the proportion of production capacity in the cement industry with energy efficiency reaching the benchmark level will exceed 30%.
Recently, the National Development and Reform Commission expanded the floating range of coal-fired power generation market transaction prices to no more than 20% in principle, and the market transaction prices of high-energy-consuming enterprises are not subject to a 20% increase. As a result, the rise in electricity prices has further increased the proportion of electricity costs in cement plant costs. In 2020, my country’s cement industry’s carbon emissions accounted for approximately 13.5% of the country’s total, ranking second only to steel among industrial industries. From the production process, it mainly includes raw material paper cups, clinker calcination and cement production. A large amount of energy is consumed in the production process. The energy consumption cost of some industry leading companies accounts for more than 50% of the production cost. Promoting industrial structural adjustment in the cement industry is the key to high-quality development and an important measure to achieve “carbon peak” and energy conservation and carbon reduction.
In the cement production process, the blower of the grinding and firing systems, which are involved in adjusting working conditions, consume a lot of power, accounting for about 30% of the total power consumption. Each ton of cement consumes about 100 degrees of power. With the popularity of roller mill systems, , the power consumption of blower accounts for an increasing proportion of the total power consumption. Therefore, the use of energy-saving blower is particularly important. Many cement companies with significant energy-saving technological transformation mainly use the world’s advanced air suspension and magnetic suspension blower.
The traditional blowers in cement plants have high energy consumption and high maintenance costs, which have put the cement industry into a dilemma of “high energy consumption, high pollution, and high costs.” Some cement plants have introduced new air suspension blowers by transforming the RAETTS blowers at the kiln head and kiln tail. As for the blower, we finally chose the air suspension centrifugal blower from RAETTS Intelligent Equipment (Guangdong) Co., Ltd. (hereinafter referred to as “RAETTS Intelligent”). Through feedback from the past two years, RAETTS blower can save more than 38% of energy compared to traditional blower.
At the beginning of the cooperation, RAETTS intelligent technicians came to conduct on-site inspections of the cement plant. After real-time testing and technical discussions, it was finally decided to use a centrifugal RAETTS air suspension centrifugal blower with a motor power of 75KW while meeting the production process. Replace the cement plant’s original volumetric RAETTS blower with a motor power of 110KW.
Comparing the two blower, it can be seen that the purchase price of the RAETTS air suspension centrifuge is slightly higher, but due to the energy saving rate of up to 38%, the annual electricity cost savings is about 25.5KW/hour*24 hours*330 days*0.65 yuan = 131,274 yuan. The entire purchase investment can be recovered by using the electricity bill saved in 1.5-2 years. If calculated based on a 20-year operation cycle, it can save millions of yuan in operating costs and create huge profits. In addition, the air suspension centrifuge has a simple structure, low noise and no need for lubricating oil. It is more reliable and environmentally friendly, and is intelligent and unattended, saving a lot of costs.Air blowers for wastewater treatment
8. The key technologies of RAETTS blower to save energy in sewage treatment: motor, impeller, bearing

In the long run, a blower with excellent performance is a banknote printing machine in a factory – it can directly save a lot of electricity bills and save money. A lot of maintenance and repair costs, saving a lot of operating costs.
RAETTS air suspension blower and magnetic suspension blower are based on the general trend of “carbon neutrality” and “carbon peak”. With the advanced aerodynamics and fluid mechanics technology from Europe and the United States, and the support of the well-known domestic R&D team, they can be used by all walks of life. Highly cost-effective advanced blower, and the technology is constantly iteratively improved, gaining a good market reputation. The main technologies of RAETTS blower include motor technology, bearing technology, impeller technology, cooling structure, compression technology, etc. Through high-tech investment and research and development, it has created a benchmark product for blower with high efficiency, low noise and low energy consumption, and is known as ” The preferred energy-saving device in the cement industry.” RAETTS blower was rated as “Energy Efficiency Star” energy-saving equipment by the Ministry of Industry and Information Technology.
Now let’s look at the three core components of Comparison blowers and RAETTS blowers:
1. Motor comparison
The efficiency of traditional RAETTS blowers is 50-60%. The motor is large and heavy, and is a technology from the last century. The motor easily generates heat during operation and is prone to burn-out when used for a long time. The motor speed control is very traditional and inconvenient.
RAETTS blower is equipped with an ultra-efficient permanent magnet synchronous motor, the motor efficiency is as high as over 97%, and the overall machine efficiency is over 87%. The motor runs more stably, has lower noise, is not prone to heat, has a lifespan of up to 30 years, and can be suitable for a variety of complex working conditions.aeration blower for effluent
2. Bearing comparison
The RAETTS air suspension centrifugal blower adopts the world’s most advanced air suspension bearing, which generates an air film through the rotation of the main shaft, so that the main shaft rotor is in a suspended state without contact with the mechanical surface. It is directly connected to the transmission and has high efficiency. The bearing has been started and stopped 30,000 times. Tested, the continuous operating life can reach 50 years without lubricating oil and no oil pollution. However, the rolling bearings of traditional RAETTS blowers have complex structures, many faults, and short service life. Replacing the bearings is time-consuming and laborious, and also requires lubricating oil. Over time, the surrounding environment will be full of pollution, and environmental protection is not up to standard.Aeration Blowers Wastewater Treatment
3. Impeller comparison
The RAETTS blower impeller is made of cast steel or ductile iron. It is processed by CNC machine tools. The tool feed is small, rough and inaccurate. The average life is only 4 years. The material strength is average. There is mechanical wear between the impellers. The efficiency is low and the performance is poor. Stable, the material is easy to deform; the RAETTS blower adopts a two-blade impeller or three-blade impeller design, with an efficiency of about 60% and a narrow operating range.
The impeller of the RAETTS air suspension centrifuge is made of aviation aluminum material AL7075 five-axis processing, which has high precision, corrosion resistance and low wear. Due to its light material, scientific and reasonable air duct design, optimized efficiency angle, high efficiency and strong deformation resistance.Sewage Treatment?Plant blower
Sewage treatment is one of the industries with heavy pollution and high energy consumption in my country. How to save energy and reduce consumption, how to improve and transform, and how to achieve dual carbon standards in the industry as soon as possible? ——”RAETTS” air suspension blower, magnetic suspension blower, and high-speed centrifugal blower have always been star-level benchmark blower products in the sewage treatment industry. They have been widely used in countries around the world, contributing to energy saving and consumption reduction and carbon neutrality in the sewage treatment industry. Make a contribution.
9. Analysis of current situation of blower configuration in cement plants
Cement production requires a large amount of energy, mainly including coal and electricity. For Conch Cement, for example, coal and power accounted for 51% of the comprehensive clinker cost in 2020. From a national perspective, the electricity consumption of the cement industry accounted for 2% of the entire society’s electricity consumption in 2020, which is higher than other building materials industries such as glass and ceramic products.
Given that the cement industry is a major energy consumer in the national economic production, the cement industry has been listed as one of the country’s key areas for resource conservation. The “14th Five-Year Plan” Raw Materials Industry Development Plan issued by the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the Ministry of Natural Resources points out that we must continue to vigorously promote the green development and intelligent manufacturing of the cement industry, improve the energy conservation and emission reduction levels of the entire industry chain, and establish cooperation with various industries. It will establish a circular economy production system that is closely connected to the discharge of similar solid waste and hazardous waste, improve comprehensive disposal capabilities and utilization efficiency, promote the construction of green mines, comprehensively promote the digital transformation of cement intelligent manufacturing, and promote high-quality development of the industry.
For the cement industry, energy conservation and environmental protection have always been an eternal topic. In recent years, under the guidance of the “dual carbon” strategy and driven by relevant environmental protection policies, a large number of companies have elevated energy conservation and consumption reduction to a strategic position. Cement companies have continued to explore the road to energy conservation and consumption reduction, and innovative technologies and products have mushroomed. Coming in droves.
The main electrical equipment in cement plants include crushers, ball mills, and blower. These three types of equipment account for more than 97% of the electricity consumption of the entire cement plant. Among them, blower account for about 20% of the entire energy consumption, and the installed capacity of the blower accounts for 20% of the total energy consumption. to 30-35% of the total installed capacity of cement plants. The environmental protection and energy saving of blower are of key practical significance to reducing the cost of cement products and improving the company’s competitiveness.
Application of blowers in the cement industry: The shaft kiln calcining air supply uses vertical kiln calcined cement, which has the characteristics of low heat consumption, low investment, and high efficiency. Because the blower has hard exhaust characteristics and pressure self-compliance, it is widely used in calcining cement air supply. For cement vertical kilns, due to changes in the height of the material layer in the kiln, the required air pressure often changes. The higher the material layer in the kiln, the higher the required air pressure and the greater the required air volume. However, the hard exhaust of the blower Gas characteristics can better meet this requirement.
Cement industry production process
At present, many cement plants have a serious phenomenon of large blower pulling small carts. At the same time, due to changes in working conditions and output, the air volume required by the system also changes. Most blower use the traditional method, that is, adjusting the opening of the inlet and outlet valves. However, this method achieves the requirements by increasing wind resistance and sacrificing the efficiency of the blower, resulting in serious losses.
10. Analysis of the shortcomings of RAETTS blowers in cement plants
RAETTS blowers originated from the technology of the 1980s and 1990s. Many design concepts and construction principles represented advanced blowers at that time. After decades of innovation, new blowers have emerged one after another, including various air suspension blowers and magnetic suspension blowers, which have become the current mainstream. Energy-saving high-speed centrifugal blower. The air suspension and magnetic suspension blower produced by Reitz introduced German technology and have become leaders in cement, sewage treatment and other industries in recent years, and have gained a good market reputation.Energy-efficient?blower
What is a RAETTS blower?
RAETTS blower is a volumetric blower. The principle is to use two blade-shaped rotors to move relative in the cylinder to compress and transport gas. RAETTS blower has a simple structure and is easy to manufacture. It is often used in sewage treatment aeration, cement transportation and other fields.
Advantages of RAETTS blower
1. The price is relatively affordable and can be purchased if the budget is insufficient;
2. The RAETTS blower is a fixed-volume blower. When operating, the air volume is basically stable. When the pressure is slightly disturbed, it can continue to transport air;
3. There is a gap of 0.3-0.5mm between the rotor and the casing, with little friction, allowing the airflow to contain certain particulate media;
4. Within a wide pressure range, it has a stable high pumping speed and can quickly discharge suddenly released gas;
Disadvantages of RAETTS blower
RAETTS blower technology in cement plants, which has been around for nearly 40 years, has become outdated and has many disadvantages, mainly as follows:
1. High energy consumption and low efficiency: efficiency 50%~80%, high energy consumption and much wasted work;
2. Large volume, requiring a large machine room: At normal temperature, the volume heat transfer coefficient of the pneumatic conveying RAETTS blower is low [23~116W/(㎡·K)], and the equipment volume is large;
3. The thermal efficiency is not high: generally, the co-flow tower type is 30%~50%, and the counter-flow tower type is 50%~75%;
4. High air consumption: Increase the power consumption of the blower and increase the capacity of the recovery device;
5. Gas-solid separation requirements are high: generally two levels of dust removal are required;Turbo Blowers for Wastewater Treatment
6. The structure is complex, covers a large area, and requires a large investment;
7. Noise greater than 105dB: The noise mainly includes aerodynamic noise radiated by the air intake and exhaust ports; mechanical noise radiated by the casing wall and motor; solid sound and electromagnetic noise radiated by basic vibration;
8. High maintenance costs: regular lubricating oil maintenance is required. Frequent lubricating oil will cause heavy oil stains around the equipment and an untidy working environment.Municipal Wastewater Treatment blower
Given that the cement industry has been listed as one of the country’s key areas of resource conservation, it is now time to comprehensively promote the digital transformation of cement intelligent manufacturing and promote high-quality development of the industry. In the cement industry’s standard improvement and transformation, the priority is to use advanced air suspension and magnetic suspension blower to replace traditional RAETTS blowers in order to gain competitive advantages in efficiency, performance, and cost, and at the same time achieve the industry’s dual-carbon goal as soon as possible.
11. Energy-saving technological transformation in the cement industry – blower selection
In the new dry process of cement clinker production, most of the raw material warehouse bottom homogenization, kiln head primary air, rotary kiln and calciner coal pulverized transportation still use traditional RAETTS blowers, which has virtually increased the number of cement companies. Electricity consumption drives up the production costs of the cement industry. In recent years, many cement companies have focused on blower upgrades during the process of technical transformation, replacing RAETTS blowers with energy-saving air suspension centrifugal blower and magnetic suspension centrifugal blower. The suspension blower abandons the speed-increasing gears, couplings, lubrication and cooling blower required by traditional blowers, improving production efficiency, process performance and operational reliability, avoiding high noise, oil pollution and other environmental pollution, and reducing equipment maintenance work volume, saving a lot of costs for the company.Aeration Blowers for Wastewater Treatment
During the technical transformation and upgrading of the cement industry, blower selection needs to be determined based on specific parameters. When selecting, excluding the overlapping parameters, if our selection parameters are very small, we recommend using air suspension blower, and the larger the parameters, the higher the parameters. , we recommend choosing a magnetic levitation blower, which is also related to the purchase budget. Specifically, cement plants need to consider these requirements when choosing suspended blower: motor efficiency, overall efficiency, energy saving rate, lifespan, noise and maintenance costs, etc. A good blower can quickly recover costs while continuing to save energy and reduce costs for the enterprise, bringing direct or indirect benefits to the enterprise.sewage treatment blower

Due to the in-depth treatment of water environment, most of the original urban sewage treatment plants are facing the problem of upgrading to meet the standards. Various new equipment and new technologies are constantly introduced, which can improve the efficiency of sewage treatment and reduce energy consumption. Among them, air suspension blower and magnetic levitation blower are At present, the world’s most advanced blower type is widely used in the upgrading and transformation of sewage treatment plants. This article focuses on analyzing the advantages of using air suspension blower in sewage treatment plants.
The air suspension blower is a type of blower in which the air rotates at high speed on the blower rotor, and a dynamic pressure effect is generated between the rotor and the surface of the foil bearing, forming a high-pressure air film to float the rotor. The air suspension blower is a technology derived from aircraft turbine engines. The products separated from it are one of the world’s top technologies in the 21st century. The core technology of air suspension blower was once monopolized in a few countries such as Germany and South Korea. Chinese entrepreneurs had to buy blower at high prices and repair them at high prices. In recent years, Reitz has continuously invested in technological research and development, introducing core technologies from Germany and other European and American countries, allowing foreign blower technologies to be implemented in China, allowing Chinese companies to use more cost-effective blower products, and bid farewell to the era of “stuck neck” blower.

Energy saving leader! The blower product preferred by many Fortune 500 companies!
The just-promulgated “14th Five-Year Plan” and “Outline of Long-term Goals for 2035” point out: Adhering to ecological priority and green development, all industries must resolutely curb the blind development of high-energy-consuming and high-emission projects, promote green transformation to achieve positive development, and promote contracts Service models such as energy management, contract water-saving management, and third-party environmental pollution management. At the same time, the Ministry of Industry and Information Technology studied and formulated the “14th Five-Year Plan for the Development of the Raw Material Industry” and also pointed out that it will continue to vigorously promote the green development and intelligent manufacturing of the cement industry and promote high-quality development of the industry.
Under the macro trend, the cement industry has sounded the clarion call for energy conservation in an all-round way
China is a major cement producer and consumer, and its cement production capacity ranks first in the world. However, factors such as low technological content and high energy consumption keep the cost of cement plants high. Especially since the outbreak of the COVID-19 epidemic in 2020, the cost of raw materials, labor, transportation and packaging of global commodities has increased significantly, and the cost of cement plants has continued to rise. How to create greater value with lower production and maintenance costs is what the cement industry is facing. common problems.
With the continuous strengthening of relevant national policies and the improvement of cement companies’ awareness of sustainable development, most cement companies have realized the importance of energy conservation and consumption reduction in reducing production costs, and the deployment of energy-saving strategies is imminent.
Blower equipment is the key to energy saving throughout the life cycle
“High pollution, high energy consumption, and high emissions” are typical characteristics of the cement industry, and its development is constantly restricted by relevant policies. Production suspensions and production restrictions are commonplace. Seeking energy conservation and consumption reduction throughout the life cycle and taking the path of green development and low-carbon development are major strategic directions faced by every cement plant. The path to achieve energy conservation, consumption reduction and green recycling throughout the life cycle through technological transformation, industrial chain expansion, hazardous waste collaboration and other channels is worth exploring and practicing.
As production equipment that plays an important role in modern cement production technology, the installed capacity of blower accounts for 30-35% of the total installed capacity of cement plants. Therefore, it is extremely important to save energy and reduce consumption of blower. If the blower efficiency of cement plants is increased from the current 65-70% (small blower are even less efficient) to more than 80%, there will be 15-35% energy saving space, and the power consumption of 1 ton of clinker or cement will be reduced by 3-4 kilowatt hours. above. A medium-sized cement production line has 7-10 large blower and more than 100 small blower. Cumulatively, it will generate considerable benefits for the enterprise.
International cutting-edge suspended blower are the first choice for cement plant standard improvement and transformation
As the most advanced blower technology in the world, magnetic levitation and air suspension blower are far more cost-effective than traditional RAETTS blowers and unipolar centrifugal blower in terms of performance, technology and effectiveness.
The air suspension blower adopts the world’s advanced air suspension bearing technology. The air suspension bearings mainly include radial bearings and thrust bearings. There is physical contact between the rotary shaft and the bearing before starting. During startup, the rotary shaft and the bearing move relative to each other to form a hydrodynamic field. This hydrodynamic force forms a buoyancy force in the radial bearing. It has multiple advantages such as low noise (<85dB), high energy efficiency (>80%), semi-permanent life (20 years+), and 1-year recovery cost.
The magnetic levitation blower is equipped with the world’s leading active magnetic levitation bearing, which achieves no mechanical contact, no wear, no need for lubrication, can monitor the status of the rotor bearing, is safe and stable, auxiliary landing bearing, actively adjusts rigidity/damping, does not limit the number of starts and stops, and prevents stalling and Surge. Magnetic levitation blower can achieve the same advantages of air levitation.
Suspension blower (RAETTS blower) with imported technology are more cost-effective
Currently, Germany’s air levitation and magnetic levitation blower technologies are second to none globally. Whether it is the material mechanics and structural mechanics design of the hardware or the software supporting design of intelligent control, they all start from the core appeal of energy saving and power saving, and are produced with ingenuity. The blower product preferred by every Fortune 500 company.
RAETTS Intelligent Equipment (Guangdong) Co., Ltd. (hereinafter referred to as “RAETTS Intelligence”) is based on the general trend of Industry 4.0 and inherits Germany’s advanced fluid dynamics technology and craftsmanship.

Conclusion: RAETTS blower brings a new direction for the standard improvement and transformation of blower in the cement industry.
The “14th Five-Year Plan” is the first five years that after China has built a moderately prosperous society in all respects and achieved its first centenary goal, it will take advantage of the situation to embark on a new journey of comprehensively building a modern socialist country and march towards its second centenary goal. As an important basic raw material industry for the national economy, the cement industry will usher in new development during the “14th Five-Year Plan” period. Judging from the lists of green factories, green mines, and energy efficiency “leaders” assessed by relevant government authorities, the cement industry is at the forefront. More energy-saving, greener and more environmentally friendly are important development directions for the entire cement industry.
We believe that air suspension and magnetic suspension blower are a great tool for energy saving and consumption reduction in the entire cement industry. As a leader in the blower team, RAETTS blower will serve the development of the industry with better technology and strength, continue to contribute to the upgrading and transformation of the entire industry, and benefit the environmental protection cause.
Air floating/magnetic floating blower: a magic weapon for energy saving throughout the entire life cycle of cement plants!
As we all know, electricity costs in the cement industry have become the third largest expense after raw material costs and labor costs. At a time when the country is focusing on energy conservation and consumption reduction and electricity consumption is tight, saving electricity bills has become a major consideration for cement plant operators. . The blower in the cement plant is one of the important equipment in the cement plant and one of the main power-consuming equipment. The blower accounts for 20%-25% of the power consumption of the entire plant, and the installed capacity of the blower accounts for 30%-30% of the power consumption of the entire plant. 35%. Among the electric equipment in cement plants, such as crushers, ball mills, blower, etc., the equipment with the greatest potential for energy saving and consumption reduction is the blower.
Cement is the main building raw material for social construction in my country, but cement companies have the characteristics of “high energy consumption, high pollution, and resource shortage”. Therefore, reducing the environmental costs of cement companies plays an important role in the development of my country’s energy-saving and environmentally friendly economy. Moreover, as an important pillar industry in the national economy, cement companies are bound to protect the environment and conserve resources.
In order to completely change the problem of huge energy consumption and low energy utilization of cement plant blower, it is necessary to solve the problem from the source, from product research and development to design, from engineering installation to maintenance management, to introduce energy-saving solutions, and ultimately achieve energy saving throughout the life cycle and cure symptoms. It also treats the root cause.
RAETTS Intelligent Equipment (Guangdong) Co., Ltd. originated from German blower technology and inherited ingenuity since 1946. It is a global innovator in energy-saving blower system solutions, a full-case design supplier and full life cycle of energy-saving blower for mid-to-high-end customers around the world. service provider. RAETTS is the first national high-tech enterprise in the world to master the core technology of air suspension and magnetic suspension dual blower. It is also the first outstanding enterprise in the industry to advocate full life cycle energy-saving services.
1. Good technology: the core of energy conservation throughout the life cycle
The blower is a machine that converts the mechanical energy of the prime mover into conveying gas and giving energy to the gas. It is an indispensable mechanical equipment in the cement plant. It mainly includes air supply blower, induced draft blower, primary blower, sealing blower and exhaust blower. In actual operation of the blower, In particular, the operating conditions of induced draft blower are harsh, and high-precision core technology is required to ensure the normal operation of the wind turbines.
The working medium of blower used in the cement industry often contains a certain amount of solid particles of different sizes and shapes. These blower work in dusty airflow. The dust particles in the airflow not only cause wear to the blower, but also cause damage to the blower blades. Dust is deposited on the surface, and the wear and dust accumulation are uneven, thus destroying the balance of the blower rotor, causing the blower to vibrate, shortening the life of the blower, and in severe cases, the blower may not work properly. The wear of blower blades is particularly serious. It not only destroys the flow characteristics in the blower, but also easily causes major accidents such as blade breakage and speeding. Therefore, it is very necessary to study the wear mechanism of blower and take corresponding anti-wear measures.
The problem of blower noise is a common problem of air compressors on the market. The huge noise generated during the operation of the equipment has also become a problem for noise control in cement companies. RAETTS has also conducted painstaking research on noise control, and the noise is about 10-15dB lower than that of ordinary suspended blower, reaching 80db. Reitz starts from the source and seizes the three major noise sources of host, motor and blower to tightly control the “lifeblood” of noise. In addition, noise control can also be achieved through shock absorption. Elastic shock-absorbing pads can be used to reduce the vibration of machine parts. In addition, setting up sound insulation covers and controlling equipment noise transmission by matching the thickness of the box board are also effective ways to reduce the noise of the air compressor.
The capacity of the blower is selected based on the maximum design output of the machine, with a certain margin left. During use, the blower is fixed at the maximum speed for a long time. Due to changes in seasons, day and night, and production conditions, the actual air volume demand is far lower than the design load most of the time; when the speed is fixed, when the blower When the air volume is excessive, it can only be discharged through the bypass duct (or the air intake volume of the damper is controlled), which results in a serious waste of power consumption. Therefore, it is of certain practical significance to carry out frequency conversion energy-saving transformation of the blower in the cement plant.
The advantages of using variable frequency speed regulation are obvious: variable frequency speed regulation saves the original energy loss in the baffle interception or the mechanical loss of the hydraulic coupler and the energy loss of internal heating of the water resistor; it achieves soft start, which has a great impact on the power grid and mechanical loads. Reduced, extending the life of the motor and blower; the blower runs below the rated speed, reducing the wear of the blower blades and baffles by the medium, reducing the damage to the bearings and seals, reducing the maintenance workload, and the vibration and vibration of the motor during operation. The noise is significantly reduced; the frequency conversion speed regulation is adopted to facilitate automatic adjustment and closed-loop control. The 4-20mA signal output by the regulator is used to adjust the motor speed through the frequency converter. The linearity is good, the dynamic response is fast, and the air volume adjustment is smooth, making the equipment Safe and stable operation in a more economical state.
2. Good hardware: the world’s advanced technology services full life cycle energy saving
The cement industry has high energy consumption and low efficiency of traditional equipment. It is of great significance to consider the rational use of energy during the design stage and implement product energy-saving optimization design. Traditional product energy-saving design mainly considers energy consumption at a certain stage such as product production or use, which has certain limitations. Reitz blower, adhering to the core technology of German Retz blower, follows the “3R” principle, namely Reduce, Reuse, Recycle, to reduce environmental pollution, reduce energy consumption, create green blower products, and protect the full life cycle operation of the project.
In order to achieve energy-saving services throughout the life cycle, RAETTS blowers adopt high-precision hardware configurations from the core to the body, and are equipped with the world’s mainstream core accessories.
RAETTS air suspension blower adopt the world’s advanced air suspension bearing technology. The air suspension bearings mainly include radial bearings and thrust bearings. There is physical contact between the rotary shaft and the bearing before starting. During startup, the rotary shaft and the bearing move relative to each other to form a hydrodynamic field. This hydrodynamic force forms a buoyancy force in the radial bearing. This buoyancy force keeps the rotary shaft in a suspended state to achieve the purpose of free rotation. This kind of bearing is different from traditional ball bearings. There is no physical contact point between the rotary shaft and the bearing during operation, so no lubricating oil is required. The energy loss is extremely low, the efficiency is extremely high, and it is suitable for a variety of working environments.
The RAETTS magnetic levitation blower is equipped with the world’s leading active magnetic levitation bearing, which achieves no mechanical contact, no wear, no need for lubrication, can monitor the status of the rotor bearing, is safe and stable, auxiliary landing bearing, actively adjusts the rigidity/damping, does not limit the number of starts and stops, and prevents Stall and surge.
In addition, RAETTS air levitation/magnetic levitation blower are also equipped with other hard-core technologies, including ultra-high-speed permanent magnet synchronous motor (PMSM), which has high speed, high power, high efficiency, small size, light weight, low noise, and a rotation speed of up to 60,000 rpm/ minutes, the motor efficiency is as high as over 95%; equipped with two-stage compression technology, the two-stage impellers are highly matched, and the pressure can reach 200kPa; it adopts a ternary flow impeller design, designed in accordance with the ternary flow theory, with optimal efficiency, made of aviation aluminum alloy, and precision Degree 0.001mm, precision machining by five-axis CNC machining, durable and anti-corrosion.
3. Good software: Intelligent unmanned control of technical services and energy saving throughout the life cycle
Most traditional blower have the phenomenon of large horses and small carts during use. In addition, due to changes in production, technology, etc., it is necessary to frequently adjust the flow, pressure, temperature, etc. of gas and liquid. At present, many units still use backward adjustment methods. The flow, pressure, temperature, etc. of gas or liquid can be adjusted by the opening of the windshield or valve. This is actually a way to artificially increase resistance and waste electricity and money to meet the requirements of the process and working conditions for gas and liquid flow adjustment. This backward adjustment method not only wastes precious energy, but also has poor adjustment accuracy, making it difficult to meet the requirements of modern industrial production and services, and has serious negative effects.
Facing the arrival of 5G, making full use of technical means and communication tools to achieve precise control and efficient management of wind turbines and achieve energy-saving management throughout the life cycle is a major breakthrough for RAETTS in facing the wave of the information age. Behind the intelligent control and unmanned duty of the RAETTS blower is the result of continuous research and development, continuous iteration and innovation of the world’s advanced energy-saving technology systems. The main features of the intelligence of the RAETTS blower are reflected in the following aspects.
The first is product intelligent integrated design. Install the inverter components, weak current circuit board box, filter and other components on the electronic control bracket as a whole, and then install the entire electronic control component inside the cabinet to avoid the defect of rewiring and debugging after the components are separated for transportation. The whole machine is assembled in modules, with high integration and small size. No new foundation is required during installation.
The second step is to build an intelligent central control module. High-speed motors, frequency converters, magnetic bearing control systems and microprocessor control panels are all designed and integrated to monitor all parameters, automatically calibrate, automatically identify, and support multiple languages. Precise control ensures performance, reduces failure rates, and achieves unmanned duty.
The third step is to realize intelligent operation control. The equipment terminal display screen performs self-checks on the blower rotation speed, pressure, temperature, flow and other operating conditions and operates at constant pressure, detects no-load, load and overload, and realizes unmanned operation through anti-surge control. Can be controlled in automatic or manual mode.
The last step is to achieve intelligent remote management. Big data platform, built-in remote control and communication functions, using PLC+GPRS/5G/4G/3G integration technology. It can be controlled by the central control room, and can also be implemented for remote maintenance and debugging. It can control single or multiple blower at the same time, and technicians can operate it with only simple training.
Faced with the special and complex wind turbine usage conditions in cement plants, intelligent unmanned control technology serves the entire life cycle of energy saving. This is Reitz’s bold attempt to realize the healthy operation of intelligent wind turbines with the help of 5G Dongfeng and the latest communication tools.

The cost of the machine is allocated to the electricity income, so the investment is small, the contribution is small, and the income is large.
4. Support the installment payment model: In order to reduce customers’ doubts, Reitz is the first in the country to launch the equipment cooperation model of “zero down payment + zero interest rate + installment payment”, allowing customers to zero risks and carry out the customer’s full life cycle energy saving to the end. . This model will bring greater energy-saving benefits to customers.
For example: A cement plant plans to assemble 150 110KW RAETTS blowers; switching to Raitz blowers can save 30% energy. It only needs to equip 150 75kw Raitz blowers, with a unit price of 200,000 yuan per unit and a purchase cost of 30 million yuan. The annual electricity bill saved by each RAETTS blower is: 110kw × 30% × 8400h × 0.6 yuan/kWh = 166,000 yuan. The annual electricity bill saved by 150 RAETTS blowers is: 166,000 yuan × 150 = 24.9 million yuan, which is equivalent to 2.075 million yuan per month. . Paying in installments with an annual interest rate of 8% over 24 months (equal principal payment system), the customer’s total electricity bill savings in 24 months is: 2.075 million × 24 = 49.8 million yuan; the total repayment amount is 30 million yuan.

“The start of the 14th Five-Year Plan: Suspension blower become the energy-saving hot cakes in the cement industry”
The just-promulgated 14th Five-Year Plan and the Outline of Long-term Goals for 2035 point out: Adhering to ecological priority and green development, all industries must resolutely curb the blind development of high-energy-consuming and high-emission projects, promote green transformation to achieve positive development, and promote contract energy management and contracts. Service models such as water conservation management and third-party environmental pollution management. At the same time, the Ministry of Industry and Information Technology is studying and formulating the “14th Five-Year Plan for the Development of the Raw Material Industry”, which states that it will continue to vigorously promote green development and intelligent manufacturing in the cement industry and promote high-quality development of the industry.
Under the macro trend, the cement industry has sounded the clarion call for energy conservation in an all-round way
In 2020, the world will encounter a once-in-a-century infectious disease epidemic, which has had a huge impact on all walks of life. Among them, global commodity raw materials and fuel materials have risen sharply, which has caused cement prices in eastern Guangdong and Fujian to increase by tens of yuan/ton in the beginning of 2021. Others Local cement prices have increased to varying degrees. In addition, off-peak production has caused most kiln companies to suspend production, and clinker inventories are relatively low. The combination of multiple factors such as the start of projects in 2021 earlier than the previous year has made cement product price increases inevitable.
In addition, in the face of high labor costs, transportation and packaging and other industries, the cost of cement plants continues to rise. The situation from macro to micro requires cement plants to deploy a longer-term all-link energy-saving strategy.
Blower equipment is the key to energy saving throughout the life cycle
The 14th Five-Year Plan and the outline of long-term goals for 2035 point out: adhere to source prevention and control, implement comprehensive policies, and strengthen coordinated control of multiple pollutants and regional coordinated governance. “High pollution, high energy consumption, and high emissions” are typical characteristics of the cement industry, and its development is constantly restricted by relevant policies. Production suspensions and production restrictions are commonplace. Pursuing energy conservation and consumption reduction throughout the life cycle and pursuing green development and low-carbon development are major strategic directions faced by every cement plant and cannot be delayed without delay. Through technological transformation, industrial chain expansion, hazardous waste collaboration and other channels, many ideas and methods have been provided to achieve energy saving, consumption reduction and green recycling throughout the life cycle, which are worth exploring and practicing.
We know that blower play an important role in modern cement production technology. The installed capacity of blower accounts for 30-35% of the total installed capacity of cement plants. Therefore, it is extremely important to save energy and reduce consumption of blower. If the blower efficiency of cement plants is increased from the current 65-70% (small blower are even less efficient) to more than 80%, there will be 15-35% energy saving space, and the power consumption of 1 ton of clinker or cement will be reduced by 3-4 kilowatt hours. above. A medium-sized cement production line has 7-10 large blower and more than 100 small blower. Cumulatively, it will generate considerable benefits for the enterprise.
International cutting-edge suspended blower are the first choice for cement plant standard improvement and transformation
At present, the preferred blower for a large number of cement plants to upgrade their standards are magnetic levitation and air suspension blower. This is currently the most advanced blower technology in the world. In terms of performance, technology and effectiveness, it is far superior to traditional RAETTS blowers, unipolar centrifugal blower, etc. More cost-effective.
The air suspension blower adopts the world’s advanced air suspension bearing technology. The air suspension bearings mainly include radial bearings and thrust bearings. There is physical contact between the rotary shaft and the bearing before starting. During startup, the rotary shaft and the bearing move relative to each other to form a hydrodynamic field. This hydrodynamic force forms a buoyancy force in the radial bearing. It has multiple advantages such as low noise (<85dB), high energy efficiency (>80%), semi-permanent life (20 years+), and 1-year recovery cost.
The magnetic levitation blower is equipped with the world’s leading active magnetic levitation bearing, which achieves no mechanical contact, no wear, no need for lubrication, can monitor the status of the rotor bearing, is safe and stable, auxiliary landing bearing, actively adjusts rigidity/damping, does not limit the number of starts and stops, and prevents stalling and Surge. Magnetic levitation blower can achieve the same advantages of air levitation.
Suspension blower (RAETTS blower) with imported technology are more cost-effective
At present, the air levitation and magnetic levitation blower technologies in Germany and other countries around the world are reliable and stable. Whether it is the material mechanics and structural mechanics design of the hardware or the software supporting design of intelligent control, they are all based on the core appeal of energy saving and power saving. They are produced with ingenuity. The blower products are preferred by a large number of Fortune 500 companies.
RAETTS Intelligent is based on the general trend of Industry 4.0 and inherits Germany’s advanced fluid dynamics technology and craftsmanship. Its “RAETTS” series air suspension high-speed centrifugal blower, magnetic levitation high-speed blower and “Explorer” high-speed blower and other products create energy-saving blower. In the new era, RAETTS has become a complete wind turbine design supplier and full life cycle service provider for mid- to high-end customers around the world. RAETTS has provided more than 10,000 sets of energy-saving blower system solutions to thousands of companies around the world, including the Fortune 500, and has saved more than 5 billion yuan in electricity and labor costs for global customers.
Conclusion: RAETTS blower brings a new direction for the standard improvement and transformation of blower in the cement industry.
The “14th Five-Year Plan” period is the first five years that after China has built a moderately prosperous society in all respects and achieved its first centenary goal, it will take advantage of the situation to embark on a new journey of comprehensively building a modern socialist country and march towards its second centenary goal. As an important basic raw material industry for the national economy, the cement industry will also usher in new development during the “14th Five-Year Plan” period. Judging from the list of green factories, green mines, and energy efficiency “leaders” assessed by relevant government authorities, the cement industry is ahead of the curve. There are 28 cement companies on the list of energy efficiency “leaders” in key energy-consuming industries by the Ministry of Industry and Information Technology in 2020. Enterprises selected. More energy-saving, greener and more environmentally friendly are important development directions for the entire cement industry.
We believe that air suspension and magnetic suspension blower are a great tool for energy saving and consumption reduction during the 14th Five-Year Plan period for the entire cement industry. The leader among them, RAETTS blower, will continue to contribute to the upgrading and transformation of the entire industry, serve the development of the industry with better technology and strength, and benefit the environmental protection cause.
So arrogant! Gezhouba Cement’s newly selected blower leads the way in energy saving
China has promised to the world that it will peak carbon emissions in 2030 and achieve carbon neutrality in 2060. According to the government work report, an action plan has been formulated to peak carbon emissions before 2030. Optimizing the industrial structure and energy structure has reached a very critical period. At the same time, the China Building Materials Federation has previously issued the “Proposal for Promoting Carbon Peaking and Carbon Neutrality in the Building Materials Industry” to the entire industry, advocating that industry enterprises fully achieve carbon peaking by 2025, with the cement industry being the most important. , advocating to achieve carbon peak ahead of schedule by 2023 and move ahead with carbon neutrality.
In this context, cement production companies must reduce energy consumption through various means to achieve carbon peak and carbon neutral standards. blower play an important role in modern cement production technology. The installed capacity of blower accounts for 30-35% of the total installed capacity of cement plants. Therefore, it is extremely important to save energy and reduce consumption of blower.
China Gezhouba Group Cement Co., Ltd. (Energy China Gezhouba Cement) is one of the 60 large-scale cement companies (groups) supported by the state. It is one of the first batch of pilot demonstration companies in the country to integrate informatization and informatization to promote energy conservation and emission reduction. It is the first cement industry in Hubei Province to pass the Clean production acceptance enterprise, China’s outstanding demonstration enterprise of green development, and China’s large cement group environmental protection benchmark enterprise.
In order to achieve energy conservation and emission reduction in accordance with high standards and strict requirements, Gezhouba Songzi Cement Co., Ltd. and Gezhouba Yicheng Cement Co., Ltd., both subsidiaries of China Energy Construction Gezhouba Cement Co., Ltd., took the lead in using RAETTS air suspension blower. Through verification and comparison, the results were good.
Gezhouba Songzi Cement Co., Ltd. purchased one RAETTS air suspension blower EXPL100-08 (75kW); Gezhouba Yicheng Cement Co., Ltd. purchased two RAETTS air suspension blower EXPL100-08 (75kW). From the analysis of existing customer energy-saving data, the energy-saving rate of RAETTS air suspension blower is more than 30%. Each 75kW blower can conservatively save 280,000 kWh of electricity per year. Calculated at 0.61 yuan/kWh of industrial electricity, each blower per year It saves about 170,000 yuan in electricity bills, making a great contribution to energy conservation, emission reduction and carbon neutrality. For example, if a cement plant is equipped with 10 75kW RAETTS blower, the electricity bill can be saved up to 1.7 million yuan per year. It will play a good demonstration role in energy conservation and emission reduction and contribute to long-term sustainable energy conservation and emission reduction.
RAETTS Intelligent Equipment (Guangdong) Co., Ltd. was established in 2011. It is a national high-tech enterprise specializing in the research and development, production and sales of energy-saving blower. RAETTS has provided more than 10,000 sets of equipment to thousands of companies around the world, including the Fortune 500. Energy-saving blower system solutions have saved global customers more than 5 billion yuan in electricity and labor costs. RAETTS technology originates from Germany and aims to allow domestic environmental protection companies to use the same blower brand as the world’s advanced blower technology.
RAETTS’s energy-saving blower are renowned all over the world and in all walks of life for their energy saving and durability. They are widely used in blowing and aeration scenarios such as industrial sewage and wastewater treatment, municipal and township sewage and wastewater treatment, and pressurized transportation of raw materials; particularly suitable industries include environmental protection industries, Sewage and wastewater treatment industry, cement industry, chemical industry, semiconductor industry, food and beverage industry, pharmaceutical industry, metal processing industry, thermal power plant, fermentation and brewing industry, health care products industry, textile printing and dyeing industry, paper industry, etc.
Especially in the cement production process, with the improvement of process requirements, there are often unique and individual requirements for blower. The raw materials, working conditions and production environment of different cement plants are different. Some cement plants need to increase the blower capacity. size and increase the blower speed to meet specific process throughput and conveying process requirements. Therefore, in the purchase of wind turbines, the energy consumption cost of the wind turbine is more valued than the initial purchase cost. “Reducing consumption equals making money.” People have begun to include the transformation of low-energy-efficiency blower as a top priority in reducing costs. Reitz has customized and developed some high-power process gas blower for cement plants. The electricity cost saved within one year by the transformation of high-temperature circulating blower is equal to the cost of a new blower, so the input output value is considerable.
In the past two years, with the vigorous promotion of energy conservation and consumption reduction in the cement and building materials industry, RAETTS has successfully established good cooperative relationships with enterprises such as Gezhouba Cement, Taiwan Cement Cement, Shuangma Cement, and Taoyuan Cement to provide energy-saving blower for the cement and building materials industry. It has set a good example.
Shipments surged 200% in the first quarter, making this blower the first choice for many cement plants
In the context of new infrastructure, agricultural and rural revitalization, and urban upgrading, the cement industry has become an important basic industry in my country’s national economy and forms the backbone of modern cities.
The global cement industry has serious carbon emissions
Looking globally, the cement industry “contributes” to 7% of total carbon emissions. If the global cement industry were considered a country, it would be the third-largest carbon emitter after China and the United States.
my country produces nearly 60% of the world’s cement, and the cement industry’s carbon emissions account for more than half of the global cement industry’s total carbon emissions. China’s cement industry accounts for about 9% of the country’s total carbon emissions and is the main source of carbon dioxide emissions in the manufacturing industry. According to estimates, to achieve global warming of no more than 1.5°C, China’s cement industry needs to reduce carbon emissions by more than 70% by 2050. In order to achieve a “zero-carbon China”, we need to consistently formulate key measures and put them into practical actions in the next few decades.
The main blower in the cement production line include raw mill circulation blower, coal mill circulation blower, kiln head exhaust blower, kiln tail high temperature blower, kiln tail exhaust blower, cement mill circulation blower, etc. It can be said that blower are major power consumers in the cement industry and are also a key indicator for the cement industry to achieve carbon neutrality.biology wastewater treatment blower
Traditional blower in the cement industry are large power consumers
The cement industry once used traditional RAETTS blowers to operate, and its disadvantages were particularly obvious. The traditional RAETTS blower uses sliding gear bearings, which consumes a lot of energy and has a complex structure. It requires a professional machine room for noise reduction and regular lubricating oil maintenance. Frequent lubricating oil will lead to heavy oil pollution around the equipment and an unhealthy working environment. tidy. The lubricating oil of the RAETTS blower is easy to leak into the cylinder, and its air volume cannot be adjusted. The only way is to use variable frequency speed regulation and air outlet duct deflation. The price of the frequency conversion speed regulation equipment itself is higher than the price of the blower, and the air outlet duct deflation is This results in a waste of energy and therefore lower efficiency.
Due to its special and complex mechanical structure and the need for lubricating oil, RAETTS blowers require regular maintenance by professionals, so the maintenance cost is high.
RAETTS blower saves energy and reduces emissions by 30%-45%
RAETTS Intelligent Equipment (Guangdong) Co., Ltd. was established in 2011. It is a national high-tech enterprise specializing in the research and development, production and sales of energy-saving blower.

After the performance, the decision was made on site to purchase multiple RAETTS blowers. Dozens of interested customers were identified at the exhibition site.
The future is here, cement plants are more inclined to choose energy-saving blower
In the cement industry, the cost of electricity has become the third largest expense after raw material costs and labor costs. In today’s tight electricity situation, saving electricity has become a major consideration for business operators; and the blower of cement plants are an important part of cement plants. One of the devices, it is also one of the main power-consuming devices.
From the perspective of economic benefits, it is very worthwhile to replace the traditional RAETTS blower with a Raitz blower. For example, a 100KW/H motor can save 37kW of Raitz blower a year, which can save about 190,000 kilowatt hours of electricity every year and save electricity bills. About 115,000 yuan, reducing carbon emissions by about 172 tons. If every enterprise saves energy and reduces emissions at this speed and efficiency, China’s “carbon peak” will arrive early!

Compared with traditional RAETTS blowers and multi-stage centrifugal blower, the advantages of RAETTS blowers are obvious. RAETTS air suspension blower have revolutionaryly achieved “zero mechanical friction + no lubricating oil + maintenance-free + low-noise operation” The four major energy-saving innovations enable energy-saving innovation to address both the symptoms and root causes, ensuring the sustainability of energy saving from R&D, design, hardware and software. This is unique among previous blower, especially RAETTS blowers. Traditional blower require lubricating oil, consume a lot of energy, are noisy, are large in size, and have a short lifespan, so they are more like “fast-moving consumer goods” for companies. However, the lifespan of RAETTS blower can reach more than 25 years (semi-permanent), and they are more like The “durable goods” of the enterprise.SBR wastewater treatment blower
Compared with air levitation and magnetic levitation blower of the same type, RAETTS’s advantages are also particularly obvious. Reitz inherits German technology and adheres to European and American industrial ingenuity, allowing foreign advanced scientific research technologies to be implemented locally, serving sewage and wastewater treatment enterprises across the country, and allowing the majority of business owners to bid farewell to the era when “blower were stuck by foreigners”. Retz’s core components are produced locally and independently, eliminating middlemen and maximizing cost performance. According to the needs of customers, Retz responds quickly to customers and takes active actions from pre-sales to in-sales and after-sales to customize energy-saving blower life cycle management solutions for customers.

RAETTS blower: Let the factory save more than 30% of energy and welcome double carbon
As a rising star in energy-saving blower, RAETTS intelligent equipment has developed rapidly in recent years and has become famous. What kind of technical strength and strategic approach does RAETTS rely on to achieve rapid growth? In what directions will breakthroughs be made in the future? With these questions, China Water Network conducted an exclusive interview with Mr. Wu Yanguang, general manager of RAETTS Intelligent Equipment, at the “2021 (19th) Water Industry Strategy Forum”.
RAETTS Intelligent Equipment (Guangdong) Co., Ltd. was established in 2011. It is a national high-tech enterprise focusing on the research, development, production and sales of energy-saving blower and compressors. The company is located in Dongguan, Guangdong, a world-famous manufacturing city and the hinterland of the Guangdong-Hong Kong-Macao Greater Bay Area. It has an existing R&D and production base area of more than 15,000 square meters and serves global customers with its superior location and resource advantages.
Let wind turbine technology not be choked by foreign countries
In Germany, the birthplace of magnetic levitation blower technology, Reitz has established ties with many German universities to obtain strong intellectual support from Germany. At the same time, it builds product lines domestically to ensure that it can provide blower products with competitive prices and technologies. In the past, the core components of magnetic levitation blower were mainly imported, and there were rigid costs. After dual-track development through the introduction of international technology and independent research and development technology, RAETTS has mastered the world’s advanced energy-saving blower technology, greatly reduced costs and improved the competitiveness of its own products.Air blower for waste water treatment system
In terms of air suspension blower, imported blower need to go through multiple layers of agents and tariffs at home and abroad. The channel cost is high, and the landing price is two or three times the ex-factory price. However, Reitz completely independently develops air suspension blower bearings, which greatly reduces production costs. In terms of maintenance, if the imported blower need to be repaired outside the warranty period, and foreign manufacturers need to send teams from their own countries to provide maintenance services, they will need to go through domestic and foreign agents. The maintenance costs can be imagined to be high, and the construction period It can take several months, seriously affecting the company’s production. Therefore, when customers use foreign blower, they not only have to buy the blower at a high price, but also have to repair and use the blower at a high price. The cost is too high.
Faced with the current situation in the industry that is faced with difficulties in out-of-warranty maintenance of imported blower, RAETTS has its own technology that can help companies save a lot of purchase and use costs. In addition, through its own research on technology, Reitz has the ability to repair advanced energy-saving blower of various domestic imported brands. It can provide cost-effective blower maintenance services, address the industry pain points of out-of-warranty maintenance of imported blower, and effectively solve the problem of imported blower maintenance. This long-standing problem solves the worries of domestic enterprises when applying advanced energy-saving blower. Moreover, Reitz has maturely mastered the two technologies of air suspension blower and magnetic levitation blower. Therefore, when customers inquire about blower energy-saving solutions, Reitz can provide a more comprehensive and objective analysis to better help customers determine the suitable blower selection for them. and energy-saving solutions.
RAETTS blower is more than just energy saving
Wu Yanguang introduced that compared with traditional blower such as RAETTS blowers and centrifugal blower, RAETTS air suspension blower and magnetic suspension blower have significant advantages in the industry:
More energy efficient. Energy saving is a significant advantage of RAETTS blower. Permanent magnet synchronous motors are used in RAETTS air levitation and magnetic levitation blower. The energy conversion efficiency reaches more than 90%, which saves 7% to 8% more energy than traditional three-phase asynchronous motors. The structure of advanced blower The form is driven by a turbine, which is more efficient than traditional positive displacement blower; in terms of blade efficiency, traditional blower are around 60%, while advanced blower impeller efficiency can reach more than 80% under the same working conditions. RAETTS blower save more than 30% energy compared with traditional blower and more than 5% compared with similar types of blower.Waste Water Treatment Blower
More environmentally friendly. The RAETTS blower adopts suspension bearings, direct transmission, zero bearing contact, no lubricating oil, and no air pollution. The noise of the traditional RAETTS blower can reach hundreds of decibels when working, and the operator must wear soundproof earmuffs to protect hearing. However, when the RAETTS blower is working, because the internal bearing is in a suspended state, there is no vibration, and the noise is much reduced, lower than 80dB. In addition, the RAETTS blower adopts an integrated structure, is small in size, occupies a small area, does not need to build a foundation, and saves space.
intellectual. RAETTS uses 5G communication technology + Internet of Things technology to achieve intelligent control and operation. It has developed a mobile phone APP to control wind turbines. You can remotely check the working conditions of wind turbines, turn them on and off, update firmware, etc. on your mobile phone, making enterprise wind turbine equipment unmanned. On duty. Through the RAETTS blower control APP, it is more convenient for RAETTS employees to recommend products to customers, and they can intuitively show customers various working conditions.
Maintenance free. Traditional blower are driven by gears and belts and often require refueling and maintenance. The internal bearings of air suspension and magnetic suspension blower do not need to be lubricated, which greatly reduces maintenance frequency and saves maintenance costs. At a time when labor costs are high, Reitz helps companies reduce labor costs.
long life. The whole machine has a simple structure and a high degree of modularity and integration. The precision parts are processed using five-axis CNC, which is more in line with the structural design and material selection of fluid mechanics. The core components are made of aviation aluminum and wear-resistant coatings, from materials and structures to Technology provides all-round protection for energy conservation.air blower for sewage treatment
Widely applicable. RAETTS blowers are suitable for water affairs, environmental protection, municipal administration, towns, and factory sewage and wastewater treatment. Intelligent frequency regulation is suitable for complex working conditions and meets different flow, flow rate, power and other needs. At present, RAETTS advanced blower have been widely used in sewage treatment aeration, blast drying, surface treatment, food and medicine, alcoholic beverages, automotive industry, electronic semiconductors, pneumatic transportation and other industries, with users all over the world.
Diversified product routes and rapid iteration of lean production
Reitz adopts a product diversification strategy. In addition to providing air suspension blower and magnetic suspension blower with conventional power, it also creatively develops portable air suspension blower, which can well meet the needs of customers who want to replace traditional small blower with advanced energy-saving blower. The small air compressor with a pressure of 2 to 7 kilograms that Reitz invested in and developed at the same time has also been officially mass-produced. This air compressor does not require refueling, is clean, and can be used in textile texturing, steel hot-dip galvanizing and other application fields. The market scale reaches thousands. billion level. The current increase in large-scale wind turbines is about 20,000 units per year, but the stock market is as high as 100,000 to 150,000 units, and the stock market of small wind turbines is one million units. If calculated at 30,000 yuan per unit, the annual iteration market size of small wind turbines is amounting to tens of billions of yuan. Therefore, Reitz not only attaches great importance to the acquisition of incremental markets, but also attaches great importance to the development of existing iterative markets.
Reitz has not only developed multiple product lines, but also has rapid design and manufacturing capabilities in the field of non-standard customized blower. Including the research and development cycle, the delivery cycle can be controlled at about 30 days, while the delivery cycle of imported blower from foreign countries is Up to 45 to 120 days. Reitz once provided blower for an electroplating wastewater treatment facility in an industrial park in Wenzhou. The water treatment pool reached a depth of 13 meters and the wind pressure required 140~150kPa. At that time, there were no ready-made products on the market, and foreign manufacturers also expressed their inability to do anything. Knowing its own R&D, design and manufacturing capabilities, I withstood doubts from all parties and decisively took on this project. It took a total of 40 days from design to delivery, and has now been in normal operation for more than 7,000 hours.
Advanced energy-saving blower help peak carbon emissions
Wu Yanguang introduced that as a global innovator in blower energy-saving solutions, RAETTS has sufficient experience in energy-saving technological transformation in municipalities and towns, industrial wastewater treatment industry, food and beverage industry, cement and steel industry, food printing and dyeing and other industries. In these fields, the use of RAETTS blower to replace traditional blower can save about 30% of energy. For better working conditions, the energy saving rate is even higher.
Regarding the issue of how to achieve energy conservation in sewage plants in the water treatment industry, Wu Yanguang talked about the Malaysian experience. All sewage treatment plants in Malaysia are constructed by Party B, but their operations are uniformly handed over to a state-owned enterprise in Malaysia called Indah Water Konsortium Sdn Bhd (‘IWK’). IWK conducted a survey and found that if the sewage plant blower adopt advanced energy-saving blower such as magnetic levitation and air suspension, the energy consumption per ton of water can be reduced by 18%. Therefore, the Malaysian government has designated that municipal sewage plants above designated size must use advanced energy-saving blower in the blower, and the government will come forward. Promote industry upgrading. Wu Yanguang expressed the hope that government departments or influential companies in the industry can also cooperate with universities, experts and other industry parties to carry out benchmark water plant promotions, advanced technology salons and other activities to promote the industrial upgrading of the domestic water treatment industry and help Global carbon peaking and carbon neutrality, energy saving and consumption reduction, protecting green waters and green mountains, and protecting Mother Earth.Sewage Treatment Aeration Blower
Looking to the future, the era of take-off
“Good products + good services” dual tracks
In developed countries, product profits often account for only 30% of total profits, while “after-sales profits” such as services and software upgrades can account for 70% of total profits. Therefore, while focusing on product production, Retz will focus on cultivating service capabilities in the future and developing after-sales markets such as software market and service market. In the near future, customers only need to pay Retz a fixed premium every year, and Retz guarantees that within the year If the customer’s blower works normally, the customer can enjoy a lifetime extended warranty.
Diverse cooperation for a win-win future
Wu Yanguang introduced that the core advantage of air suspension blower and magnetic suspension blower is to create benefits for customers through energy conservation. At present, most of the industry adopts the full payment method of purchase. Customers must first purchase the wind turbine in full, and then receive benefits after the wind turbine is installed. Customers are under great pressure to pay. Retz’s customers can pay in installments and gradually pay off the payment on a quarterly basis after the wind turbines realize energy-saving benefits, providing customers with smoother spending options. At the same time, some financial leasing institutions can also be introduced to reduce customers’ payment pressure. The reason why Reitz can support the installment payment method is because Retz’s advanced energy-saving blower have realized remote intelligent control. If there are any violations, Retz has the “right to shut down” to ensure the safety of payment.
