大型双曲线自然通风冷却塔的噪声治理

Noise elimination of large hyperbolic natural-draft cooling tower

对为上海吴泾第二发电有限责任公司2×600MW火电机组建造的大型双曲线冷却塔投用后造成的噪声污染进行了分析,并就噪声治理的方案、设计、施工和效果作了详细的介绍,为我国首次针对大型双曲线自然通风冷却塔的噪声治理,所取得的宝贵经验可供同类冷却塔的建设借鉴。

Noise contamination rose after the commission of the large hyperbolic naturaldraft cooling tower constructed for 2×600 MW coalfired units of Shanghai Wujing 2nd generation Co. Ltd.. The noise source of the cooling tower was analyzed and studied. The plan of the noise treatment, the design, construction and installation of the sound proof shield were introduced in detail. The field test for the effect of the sound barrier was made and the results were given. The valuable experiences achieved in the unprecedented noise treatment in our country for large hyperbolic naturaldraft cooling tower will provide a guidance for construction of similar cooling tower.
