摘要
针对火电厂自然通风冷却塔的噪声污染,通过分析研究冷却塔噪声特性,以辽宁某电厂冷却塔噪声控制为例,根据厂界及敏感点噪声控制目标,利用CADNA_A软件进行分析和预测,采取消声装置和声屏障相结合的噪声控制技术,使厂界及敏感点噪声达到相关标准,取得了理想效果,为同类工程噪声治理提供参考。
This paper focused on the noise pollution of natural ventilation cooling tower in power plant. Taking cooling towers in a power plant in Liaoning as an example,the noise characteristics and noise control of cooling towers were analyzed and studied. According to the noise control target of factory circle and sensitive points,the noise distribution was analyzed and forecasted by CADNA_ A software. The result showed that the noise in factory circle and sensitive points reached the relevant standards and achieved the desired results by the combined applica-tion of silencer and sound barrier. This approach provides a reference for similar project.
