      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. When the floor plan is arranged, the blower is close to the side of the boiler room. Which one is good, 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.

      During the use of Roots blowers, the current is too high and the motor is overloaded. There are many reasons for the high currents of Roots blowers. Today, Xiaoyuan Xiaobian came to analyze the reasons for the roots blower current?

      1.Pipe blocked

      Common causes are mainly blocked pipes, fan outlets are not stable, wind does not extinguish, pressure rises, and motors cause overpressure overload, which causes the Roots blower ammeter to rise.

      2. Reasons for lubricants

      If the Roots blower has insufficient lubricant, the fan will continue to operate without oil. Impeller failure friction and gear wear will increase, which will increase the motor load, which will only increase the motor load and accelerate the loss.

      3. Misoperation

      During operation, current overload can also be a problem. For example, if a non-return valve is installed in reverse and the gate valve is not fully opened, this operation may cause the motor to burn instantly and should be performed as specified during operation. Don't just cause unnecessary trouble.

      4. Problems with Roots Blower itself

      Roots fan manufacturers have their own quality problems. When installing a fan, the clearances of many components are poor, which will cause additional friction. In addition, some components may be damaged, increase the load on the motor, and the fuse may blow.

      The high-pressure fan itself also generates a certain temperature when it is operating normally, but that is normal. However, there are also some reasons that cause the high-pressure blower temperature to be high. The main reasons are as follows:

      (1) Poor lubrication quality. The purpose of lubrication is to prevent the dynamic and static parts from directly contacting to produce friction, but to form friction between solid and liquid. If the quantity of lubrication is insufficient or the quality is poor, the dynamic and static parts will be directly heated by friction, or the heat cannot be taken away by the lubrication, and the high-temperature fan bearing temperature will rise.

      (2) Poor assembly of rolling bearings. If the tightness between the inner sleeve and the shaft is insufficient, the gap between the outer sleeve and the bearing seat is too large or too small.

      (3) The sealing felt is too tight and generates heat.

      (4) The bearing of the high-pressure blower is too large to bear the impact load, which seriously affects the stability of the lubricating film.

      (5) Insufficient or interrupted cooling water in the bearing of the high-pressure blower, which affects the generation of heat and raises the bearing temperature.

      (6) The quality of high-pressure blower bearings is poor. The quality of the sliding bearing is poor, and the contact of Ugin is not good or the child is born; cracks, chipping, peeling, etc. on the rolling bearing surface of the rolling bearing will destroy the stability and uniformity of the oil film, and the surface will cause the bearing to heat up.
