采用隔吸声屏障治理抚顺发电厂双曲线冷却塔噪声

抚顺发电厂供热机组两座双曲线自然通风冷却塔的噪声对该厂北厂界和敏感点(抚顺卫校)构成危害,经测试昼间和夜间噪声均超过排放标准。经方案论证,设置弧形鱼鳞状吸声型声屏障,噪声均达到相关标准规定,取得较好的环境与社会效益。

There are two hyperbolic natural draft cooling towers of the heating units in Fushun Power Plant, the noise from the towers continually affects the sensitive point of Fushun Medical School and the north plant boundary. Based on the monitoring test, the noise exceeded the national noise standards in daytime and nighttime. The noise could reach the relevant standards and achieve better environmental and social benefits through setting the arc fish scale sound barrier by simulation and plan evaluation.
