Noise and Prevention of Cooling Tower

Cooling tower plays an important role in modern industry, but the noise problem is gradually concerned by people. The noise of cooling tower mainly comes from the air flow noise generated by the interaction between water flow and air, water noise and mechanical noise generated by fan operation. These noises not only affect the working environment, but also may affect the lives of the surrounding residents.

Characteristics of 1. Cooling Tower Noise

Cooling tower noise generally belongs to the low frequency noise, the sound pressure level is high, the propagation distance is far. Especially in the dead of night, the noise of the cooling tower is more prominent, which can easily affect people's rest.

Hazards of 2. noise

Long-term exposure to the noise environment of the cooling tower will not only affect people's rest and work efficiency, but also may cause damage to people's physical and mental health, causing irritability, insomnia and other problems.

Prevention and Control of 3. Cooling Tower Noise

1. Source control: optimization of cooling tower design, selection of low-noise equipment, such as the use of high-efficiency low-noise fan, muffler spray water system. In addition, the operation mode of the cooling tower can be improved, such as adjusting the wind speed, flow rate, etc., to reduce noise.
2. Transmission control: add muffler, sound insulation cover and other noise reduction equipment around the cooling tower to reduce the transmission of noise. At the same time, through the establishment of sound insulation walls, green belts, etc., to block the transmission of noise.
3. Transmission area control: In the area where the noise is more affected, personal protection can be taken, such as wearing earplugs, earmuffs, etc. In addition, publicity and education can be used to raise public awareness of noise hazards and encourage everyone to participate in noise prevention and control work.
Policies and regulations: The government should issue relevant laws and regulations to limit and manage the noise of cooling towers. Cooling towers with excessive emissions should be required to be rectified or discontinued.

4. Summary

Cooling tower noise problem can not be ignored, should take a variety of measures to prevent and control. Through source control, transmission route control, transmission area control and the formulation and implementation of policies and regulations, the impact of cooling tower noise on people can be effectively reduced. At the same time, the public should also raise awareness of noise hazards and participate in noise prevention and control work.
