摘要
介绍一种电站方舱的降噪设计。根据降噪要求、方舱舱体大小、发电机组特性,重点进行了进排风道降噪和排烟降噪设计,既保证了机组的正常运行,又有效地解决了噪声问题。试验结果表明:本电站方舱噪声由原来的108 dB(A)降至75dB(A)以下,达到设计要求。
The paper introduces a noise suppression of an electric power shelter. According to the noise demand, the size of shelter body and the performance of the diesel generator group, it concentrates on the noise suppression of inhaling air and exhausting gas pipes. The test shows that the noise of the electric power shelter is less then 75 dB ( A ) and the design fulfils the demand.
