Cooling tower noise control primarily involves fan noise management, noise control, pump noise management, and vibration pollution control.
The cooling tower generates significant noise pollution during operation, which affects the residents' living and working environments. The noise sources of the cooling tower are composed of the following parts:
1. Fan intake and exhaust noise
2. Spraying noise
3. Fan speed reducers and noise;
Cooling tower pumps, piping, and valve noise.
The primary noise sources are the intake and exhaust noise of the fan, as well as the spray noise. The fan radiates noise through its intake and exhaust ports and the tower body. The exhaust port noise is 5-10 dB(A) higher than the intake port noise, with a frequency spectrum primarily consisting of low-frequency continuous noise. The spray noise, produced when the recirculating hot water falls from the spray device and impacts the accumulated water in the bottom water pan, is a high-frequency noise. The intensity of the spray noise is related to the spray height and the flow rate per unit time.
Hangzhou Su Tai's years of engineering experience conclude: The overall noise level of the cooling tower is around 85dB(A).
The primary modes of noise transmission are through air and solid transmission.
