工业锅炉是应用广泛的设备,其所配备的鼓、引风机产生的噪声污染严重,如何消除这种危害并考虑得更加经济合理,一直是环保工作者探求的目标.通常对鼓风机安装进口消声器,一般可使其噪声降低10—15分贝(A).若采用风机隔声罩,则可使鼓风机的噪声降低达30—40分贝(A).但由于引风机在较高的温度下运行,往往安装在机房外,因而其机壳等机械辐射噪声影响的范围很大,治理较困难.为了消除其噪声污染并
Industrial boilers are the most widely used equipment and their noise pollution caused by drums and induced draft fans is serious and how to eliminate such hazards and consider them more economical and reasonable has always been the goal of environmental protection workers. Generally, the noise can be reduced by 10-15 dB (A) .If the fan noise enclosure is used, the noise of the blower can be reduced by 30-40 dB (A), but because the induced draft fan operates at a higher temperature, Installed in the machine room, so its chassis and other mechanical radiation noise a wide range of governance more difficult.In order to eliminate its noise pollution and
