      Fan energy saving transformation

      At present, motors supporting fans in various types of machinery and electrical equipment in various industries in China account for about 60% of the national installed capacity of motors and consume about one-third of the country's total power generation. It is particularly worth mentioning that most fans have the phenomenon of large carts during use. In addition, due to changes in production and technology, it is necessary to constantly adjust the flow, pressure, and temperature of the gas; many units still use them. A backward way to adjust the degree of opening of the air baffle or valve to adjust the flow, pressure, temperature, etc. of the gas. This is actually to meet the requirements of the gas flow regulation of the process and working conditions at the cost of wasted electricity and money by artificially increasing the resistance. This backward adjustment method not only wastes precious energy, but also has poor adjustment accuracy, and it is difficult to meet the requirements of modern industrial production and services. The bad effects are very serious.

      In recent years, with the rapid development of power electronics technology, computer technology, and automatic control technology, electrical transmission technology is facing a historical revolution, that is, AC speed regulation has replaced DC speed regulation and computer digital control technology has replaced analog control technology. trend. Motor AC frequency conversion speed regulation technology is a major means to save power, improve process flow to improve product quality and environment, and promote technological progress.

      Harm of Boiler Blower Noise and Its Prevention

      1. Harm of environmental noise pollution

      The impact and harm of noise on the human body can generally be divided into two aspects: labor protection and environmental protection. The former refers to endangering human health and causing various diseases. The latter refers to disturbing the quiet environment and affecting people's normal work and life. The harm of noise to human health is mainly manifested in: damage to hearing, causing noise-induced deafness; leading to cerebral cortex excitement and balance imbalance, cerebrovascular function damage; damage to the system, causing digestive disorders; interference to people's normal life, rest, language conversation and daily life Work learning, distracting and reducing work efficiency.

      2. Basic principles of noise management

      There are three main factors that contribute to noise pollution: sound sources, media, and receivers. Only when these three exist at the same time can the listener be disturbed. Starting from these three aspects, the purpose of controlling noise can be achieved by reducing the sound source, limiting the transmission of noise, and blocking the reception of noise. In specific noise control technologies, three types of sound absorption, sound insulation, and noise reduction can be used. Measures.

      2.1 sound absorption

      When sound waves are incident on the surface of an object, part of the sound energy is absorbed by the object and converted into other forms of energy, which is called sound absorption. The sound absorption performance of a material is expressed by the absorption coefficient. The larger the sound absorption coefficient, the better the sound absorption performance of the material. The sound absorption performance of a material is related to the material's properties, structure, angle of incidence of sound waves, and frequency of sound waves. The sound absorption mechanism of porous sound absorbing materials is: there are numerous small holes in the material that penetrate through each other. When sound waves are incident on the surface of these materials and then into these small pores, the air movement in the pores is caused to abut The air on the wall of the hole and the surface of the fiber is difficult to move due to friction and viscous motion resistance, so that the sound energy is converted into heat energy and consumed. Therefore, sound-absorbing materials with good performance must be porous, and the holes must be connected with each other, and the through holes must communicate with the outside world so that sound waves can enter the material.

      For example, the sound absorption coefficient of a 10cm-thick ultra-fine glass wool is 0.87 for a 1000 Hz sound wave.

      2.2 Sound insulation

      The method adopted for sound insulation is to close the noise source so that the noise is controlled in a small space. This sound insulation structure is called a sound insulation cover. When the sound wave encounters the shield, due to the change in the characteristic impedance of the interface, part of the incident sound energy is reflected, part is absorbed, and part of the sound energy penetrates the shield and continues to propagate. The sound insulation performance of a material can be expressed by the sound transmission coefficient. The smaller the sound transmission coefficient, the less the sound energy transmitted through, and the better the sound insulation performance of the material. The sound insulation performance of a material is related to the structure and properties of the sound insulation body and the frequency of the incident sound wave.

      2.3 Silence

      Sound reduction is to fix the porous sound-absorbing material on the inner wall of the airflow channel or in a certain way to achieve the purpose of reducing aerodynamic noise. The amount of noise reduction can generally reach 10-50 decibels.

      3. Fan noise management technology

      The noise of the blower and induced draft fan in the boiler room is generally around 90 decibels. Because the temperature of the boiler flue gas being conveyed is as high as 180 ° C, the use of closed sound insulation can cause poor heat dissipation, excessive motor temperature, and even burn the motor. Therefore, in the process, the fan noise reduction and energy saving are combined. Through practice, the comprehensive control plan for energy saving and noise reduction of boiler fans is as follows: keep the process layout of the boiler room unchanged, place blowers and induced draft fans in sound insulation rooms, connect them to the host with ventilation pipes, and place them on the top of the sound insulation room. An air inlet is installed on the top or wall, and a muffler is installed for air intake in the machine room. In the plan layout, place the blower close to the side of the boiler room, the air inlet is on the upwind side, and the motor is placed in the middle of the air flow channel. When the boiler is running, due to the negative pressure generated by the blower in the sound insulation room, a large amount of outdoor fresh air will automatically enter the sound insulation room. First, the heat exchange with the induced draft motor will cool and cool the room, and the indoor temperature will be maintained at about 50 ° C.

      What is the comparison and analysis of the operating principles of roots fans and air suspension fans?

      Roots blower operation principle:

      Roots blowers are positive displacement gas compressors. They are:

      ①Forced flow, within the design pressure range, when the resistance of the pipe network changes, its flow change is small. In the workplace where the flow requirement is stable and the resistance change is large, it can be automatically adjusted and the work adaptability is strong. Low price compared to centrifugal blowers.

      ② It has a lot of noise. The Tianjin blower has the disadvantage of leaking lubricant to the cylinder. At the same time, the air volume cannot be adjusted. It can only use variable frequency speed regulation and air outlet pipe deflation. High, the exhaust of the air duct will cause energy waste, so the efficiency is low, so it is very suitable for use in industrial sewage plants, but because of its high noise and low efficiency, it has been widely eliminated in advanced international sewage treatment processes. In China, wastewater treatment is in the early stages of development. Due to its low value, ease of operation, and traditional habits, many projects are still in use.


      2. Principle of air suspension centrifugal blower:

      ①Bearing material: permanent magnet

      ② The main shaft of the motor rotates at high speed through a high-speed motor. At the same time, an air film is formed between the main shaft and the bearing. The air film generates pressure to cause the bearing to levitate while driving the impeller.

      ③Since it adopts active oil-free air suspension bearing, no lubrication device is needed, and the structure is simple and accurate.

      ④ Tested technology: ECS / ACM for aircraft startup.

      ⑤ 50 years (semi-permanent) 20,000 start-stop tests.
