矿用通风机的降噪结构设计研究

Study on Noise Reduction Structure Design of the Mine Fan

针对煤矿通风机在运行过程中的噪声较大的现象,分析了通风机噪声产生原因,并对进气口和出气口分别进行降噪结构设计,有效解决了矿场中的噪声污染问题,达到了较好的降噪效果。

In order to reduce the noise and create a better work ing environment in the mine, the noise reduction structure design of the air inlet and the air outlet, the noise reduction structure design of the absorption body and the diffusion cylinder core barrel are carried out respectively, and the noise is well controlled The noise reduction effect of the system can effectively solve the problem of noise pollution in the mine.
