一、前言节流降压小孔喷注消声器,已经广泛应用于工厂汽体排放噪声控制中.尤其在锅炉排放中消声效果十分显著.贵州铝厂热电厂在锅炉小孔喷注消声器制作过程中,作了一些行之有效的探索.二、小孔喷注消声器参数改进贵州铝厂热电厂有六台75T锅炉,主要排放过热蒸汽及安全阀排汽,排汽噪声为A声级70～120dB(距排汽管1500m～5m处测).噪声污染区间约为2000m~2,在该区间内的办
I. Introduction Throttle orifice injection muffler, has been widely used in the factory emissions of noise control in the body, especially in the boiler emissions muffler effect is very significant. Guizhou aluminum plant thermal power plant in the production process of small hole injection muffler , Made some effective exploration.Second, hole injection muffler parameter improvement Guizhou Aluminum Plant Thermal Power Plant has six 75T boiler, the main discharge of steam and safety valve exhaust steam exhaust noise is A sound level 70 ~ 120dB ( From the exhaust pipe 1500m ~ 5m at the test.) Noise pollution interval is about 2000m ~ 2, within the range
