锅炉房的噪声污染是目前我国环境保护中一个比较突出的问题,特别是引风机,由于散热需要,常常被安装在车间外面,或设置在不能密闭隔声的机房内,因而受机壳辐射的机械声直接影响的范围很大,成为一种难以治理的污染源。消除这种公害一直是环保工作者探求的目标。本文提出的方案是在调查研究和工程实践的基础上,利用锅炉房的特有工艺条件,把节能和降低鼓风机和引风机的噪声综合起来解决作一个新的尝试。这样做不仅使锅炉房的噪声得到根本改善,而且有一定的经济效益。其投资仅比普 Noise pollution in boiler room is a prominent problem in environmental protection in our country. In particular, induced draft fan, which is often installed outside the workshop due to heat dissipation, is installed in the engine room which can not be sealed and soundproof, Mechanical sound has a direct impact on the scope of a difficult source of pollution control. Elimination of such pollution has always been the goal sought by environmentalists. The solution proposed in this paper is to make a new attempt to solve the problems of energy saving and reducing the noise of blower and induced draft fan on the basis of investigation and engineering practice and using the unique process conditions of boiler room. This will not only make the boiler room noise has been fundamentally improved, but also have some economic benefits. Its investment is only more than Pu
