我矿空压机站使用三台L-100/8型空压机,电机功率均为500千瓦。运转时空压机总进风口外一米处噪声级高达110～120分贝,加上空压机站的位置高于地势平坦的广大居民区,噪声辐射面广,严重地影响了附近居民的环境。虽然早年曾经采用地坑式通道(长约40米,通道截面积1.8×1.5米,红砖水泥砌筑),使空压机的进风口分别与此通道密闭连接,将噪声引向居民较少的方向,但问题并未根本解决。地坑式总进风口外一米处的噪声级仍为105分贝,远远超过了国家《工业企业噪声卫生标准》。
I mine air compressor station using three L-100/8 air compressor, motor power is 500 kilowatts. In operation, the noise level at the meter inlet of the air compressor reaches as high as 110 to 120 dB at a meter, and the location of the compressor station is higher than that of a broad residential area with flat terrain. The noise emission is broad and seriously affects the environment of nearby residents. Although early years have used the pit-type channel (about 40 meters long, the channel cross-sectional area of 1.8 × 1.5 meters, red brick cement masonry), the air inlet of the compressor were sealed with this channel, respectively, the noise to less residents The direction, but the problem has not been solved. The noise level at one meter outside the pit inlet is still 105 dB, far exceeding the national “noise level of industrial enterprises”.
