摘要
分析了锅炉房风机噪声产生的机理及危害,综合利用治理噪声的三种措施:吸声、隔声、消声,针对锅炉房风机噪声治理提出两种方案:保证风机压力系数不变的前提下,增大风机叶轮的直径;将风机集中于隔声室中,降噪节能。
This article analyzes noise gennerated mechanism and harm,three measures for comprehensively utilizing noise governing, sound absorption,sound insulation and silencing.Being directed against the fan noise governing,both governing plans are proposed,under pressure coefficient unchanged to increase the diameter of fan centrifugal impeller,to concentrate fan into a sound insulation room for noise reduction and energy saving.
