The noise source of the closed cooling tower is generally the noise of the fan inlet and exhaust, the noise of the fan reducer and the motor, the noise of the closed cooling tower centrifugal water pump, the noise of the pipeline and the valve and the noise of splashing water. The operation of the cooling fan will produce rotating noise, mechanical noise and intermediate noise. Their noise has broadband characteristics. Its noise value is not very large, but it is very penetrating. It will endanger the surrounding citizens and buildings. This is also one of the factors that generate noise sources.
The operation of the fan is the noise of the air inlet and exhaust and the noise of water splashing. The fan discharges heat according to the exhaust port and the tower. Therefore, the noise of a closed cooling tower has the following treatment methods. Before the falling water hits the water immediately, the falling water first uses a silent friction method according to the excessive on the slope, which can reasonably reduce the knocking sound of the falling water and achieve the treatment effect.
Noise solutions of closed cooling towers:
1. Muffler: Install a muffler at the inlet and outlet of the exhaust fan of the closed cooling tower to control the noise reasonably.
2. Installation of sound insulation wall: It can be installed for the noise of the inlet and outlet of the closed cooling tower, the splashing sound of water, the mechanical noise of the reducer and the motor, to control and reduce the noise of the sound insulation wall.
3. Choose silencer pad: put the silencer pad in the lower part of the closed cooling tower, and support it with a metal mesh or put it on the drain pan to reduce the noise of water splashing.
The above is the relevant introduction about the closed cooling tower, I look forward to some assistance to everyone.
