柴油发电机房的噪声控制技术

柴油发电机组是一种广泛使用的备用供电设备,机组引发的环境噪声污染问题日益得到重视.对某电信局紧急备用的柴油发电机组进行噪声频谱特性分析和周围环境状况的分析,针对性地提出吸声、隔声、消声、减振以及通风散热的治理措施.经过治理后,达到了环境噪声Ⅱ类区域排放标准的要求,同时也满足了柴油发电机组工作时的通风散热要求.

The Noise Control of Diesel-Electric Engines

Diesel generator set is one of stand-by electrical supply equipments which are widely used.The problems of environment noise pollution which is caused by diesel generator set have been attached more importance.Taking an emergency stand-by diesel generator set of a telecommunication bureau for instance,the noise spectrum analysis and the surrounding environmental condition analysis have been carried out in this paper.Some noise control treatment measures are introduced which include sound absorption,sound insulation,noise elimination,vibration reduction,airiness and heat elimination.After the measures have been taken,the environmental noise discharge standard of II class area and the airiness and heat elimination requirements of diesel generator set have achieved.
