我厂采用3.9MPa锅炉蒸汽带动汽轮机,生产压缩空气供发酵车间使用.汽轮机由于锅炉蒸汽压力变化或发酵车间用气量的变化而要间断排气,排气口近1m处噪声高达130dB(A),严重影响汽机房及其附近车间的工作环境和工人的身心健康,长此以往,还影响职工下班后的休息和睡眠.为解决这一问题,我们决定在排气口上安装一个消声器.购买这么大一个消声器需要10万元左右,效果还不一定好,最后决定自行设计制作一个.结果只花了1400多元,使距排气口1m处的噪声由原来的130dB(A)降低到90dB(A),而其重量不到250kg.基本上消除了噪音污染问题.
Our factory adopts 3.9MPa boiler steam to drive the steam turbine to produce compressed air for the fermentation workshop.As the steam pressure of the boiler changes or the change of the gas consumption in the fermentation workshop is interrupted, the noise of the exhaust outlet is up to 130dB (A) Seriously affecting the work environment and the workers ’physical and mental health in the steam turbine engine room and its nearby workshops. After a long period of time, it also affected employees’ rest and sleep after get off work hours. To solve this problem, we decided to install a muffler on the exhaust port. Need about 100,000 yuan, the effect is not necessarily good, and finally decided to design their own. The result only spent 1400 yuan, so that the noise from the exhaust port 1m from 130dB (A) to 90dB (A), and Its weight is less than 250kg. It basically eliminates the problem of noise pollution.
