冷却塔的落水噪声及其防治措施

A Discussion on Falling Water Noise from Cooling Tower and Metheds for Its Prevention and Control

根据冷却塔噪声的实测结果,就冷却塔噪声的成因、性质及其治理方法进行了分析。冷却塔的噪声可视为点声源,其治理方法可分为塔内和塔外两条途径。塔内治理可采用冷却塔落水消能降噪装置,塔外治理可采用声屏障方法。

Causes of formation of noise from cooling towers,characteristics of the noise as well as methods for controlling the noise are analyzed based on actual measurement of noise from cooling towers.Noise from cool - ing towers can be considered as a point source of sound and there are two ways for its control,i.e.,inside-tower method and outside-tower method.For inside-tower control,an energy-eliminating and noise-lowering device for the falling water from cooling towers may be used,while for outside-tower control,acoustic shielding method may be used.
