Closed Cooling Tower noise and its prevention and control measures:
Closed Cooling Tower noise source strong
Closed Cooling Tower noise to fan sound and falling water noise. Fan noise is the noise generated when the fan is running, mainly aerodynamic noise, including rotating noise and eddy current noise, but also reducer noise and drive the motor noise. Dropping noise is the Closed Cooling Tower from the falling water when the device, and the tower chassis and the water generated by the impact of falling water, its value and the height of water and unit time of water flow, generally second only to the fan noise. In addition to the noise, there are circulating water pump, with the motor noise, pipeline radiation noise.
Closed Cooling Tower noise by line sound source attenuation; 1-0, the Closed Cooling Tower noise by point sound source attenuation. According to the actual measurement and expert consultation, when the Closed Cooling Tower is less than 2001, in the equivalent diameter range, the Closed Cooling Tower noise is the surface source, the noise level does not change; between 1 times the equivalent diameter and 2 times the equivalent diameter, When the predicted distance is greater than 2 times the equivalent diameter of the Closed Cooling Tower, the noise is attenuated by the law of the point source. For different models, the size of the Closed Cooling Tower, 0 and 0 should be based on the actual situation or consult the relevant experts to determine.
The forecasting model is suitable for small Closed Cooling Towers, according to the cost of public buildings for air conditioning with Closed Cooling Towers on the negative impact of the environment and countermeasures for the forecast model for civil building Closed Cooling Towers.
Since the noise of the Closed Cooling Tower affects the prediction mode and the size of the Closed Cooling Tower, the distance between the predicted point and the Closed Cooling Tower is different, and the delineation of the different prediction modes is not yet clear. In the Closed Cooling Tower mode selection and range division, the relevant experts can be consulted The
Prevention and Control Measures of Closed Cooling Tower Noise
The noise of the Closed Cooling Tower affects work and life, which brings inconvenience to people. There are four main ways to reduce the noise pollution of the Closed Cooling Tower: rational layout, reasonable choice of Closed Cooling Tower, control of transmission, to protect the body.
Reasonable layout is to achieve functional partition, static and dynamic separation. Closed Cooling Tower due to the large noise source, should be placed in the production area or the active area of the lower noise requirements of the region. To avoid distance from the office, dormitory, residential areas and other noise-sensitive buildings too close, affecting the work of workers and residents. Between the different functional areas set the noise protection distance, the ambient noise is higher in the functional area near the noise source side of the noise requirements of the relatively low construction or room.
