基于声学模拟分析的大型火电厂降噪技术应用

Application of the Noise Reduction Technology in Large-scale Thermal Power Plants Based on Acoustic Simulation Analysis

通常情况下,电厂厂界噪声超标并非是由于单一的某个设备设施导致的,而是多种声源叠加贡献所致,简单的技术方法很难筛选出哪些噪声源是起主要超标贡献作用的,因而需要对全厂噪声源进行系统性的采集监测,借助声学仿真软件进行全厂噪声模拟分析,分析出每个厂界监测点的噪声来源,进而采取合理、有针对性地噪声治理措施。

Under normal conditions, it is not single equipment that leads to excessive noise at the boundary of power plant, but the superposed contributions of multiple acoustic sources, so it is very difficult to screen out which noise sources are the main contributors to noises out of limits by simple technical approaches. Therefore, it is necessary to systematically collect and monitor noise resources within the whole plant and conduct a whole-plant noise simulation analysis with the aid of acoustic simulation software. In this way, the noise source of each monitoring point at the plant boundary can be analyzed, and then reasonable and targeted noise control measures can be taken.
