火电设备噪声机理分析及综合整治

Analysis of Noise Mechanism and its Control in Thermal Power Station

本文分析了火电设备噪声产生的机理,对火力发电设备所产生的噪声进行了综合整治,对设备的进气处噪声采取安装消声器的方法,对未达到降噪标准的部分通过在发声设备外侧敷设吸声材料,通过吸声材料内耗衰减。该方法在控制生产性噪声上已取得较好效果,对火电厂降低噪声是一种有益的尝试。

The paper analyses the mechanism that leads to the noise in the thermal power station and introduces ways to control the noise by installing mufflers at the gas inlet of the equipment and laying sound deadening material on equipment for the unreachable parts and by doing so, good effects have been achieved.
