What are the measures to solve the noise problem of Industrial Boiler Fan in Chemical Plant
What are the measures to solve the noise problem of industrial boiler fans in chemical plants? At present, in many enterprises, industrial production and heating demand, the use of boilers is very popular. However, due to the many influencing factors of boiler noise, which affects the work and life of the surrounding residents and endangers people's health, it is urgent to control the fan noise of industrial boilers in chemical plants. The sound shell of blower and induced draft fan in boiler room is generally about 90 dB.
Because the flue gas temperature of boiler is as high as 180 ��, if closed sound insulation is used, the heat dissipation will be poor, the motor temperature is too high, and even burn out the motor. Therefore, in this process, the combination of general purpose Fan noise reduction and energy saving. The practice shows that the comprehensive treatment scheme of energy saving and noise reduction of boiler fan is to keep the technological arrangement of boiler room unchanged, put the blower and induced draft fan in the sound insulation room respectively, and connect with the main engine through t-shaped joint. Ventilation ducts, open air intake on the top or wall of the soundproof chamber, and installation of silencers for the intake of the engine room.
When arranged, the fan is close to the side of the boiler room, the air inlet is in the upper part, and the motor is placed in the center of the air flow channel. When the boiler is in operation, a large amount of outdoor fresh air will automatically enter the sound insulation room because of the negative pressure produced by the blower in the sound insulation room. First of all, heat transfer cooling with induction fan motor, indoor temperature Keep it at about 50 ��.
