我厂设备陈旧,运转中产生噪声较大,噪声污染比较严重,特别是沸腾炉的D60—200罗茨风机(SO_2)发出的噪声危害尤为严重,经测定其噪声数据如下: D60—200罗茨风机噪声测定值测点位置距离高度噪声级 (m) (m) [dB)A)] 风机 1 1.2 108 机房东面 2 1.2 93 机房南面 2 1.2 92 机房西面 2 1.2 98 机房北面 2 1.2 90
I plant outdated equipment, operating noise, noise pollution is more serious, especially the boiling furnace D60-200 Roots blower (SO_2) issued by the noise hazards are particularly serious, the measured noise data are as follows: D60-200 Roots blower Noise Measurement Point Location Distance Height Noise Level (m) (m) [dB] A)] Fan 1 1.2 108 East of the engine room 2 1.2 93 South of the engine room 2 1.2 92 West of the engine room 2 1.2 98 North of the engine room 2 1.2 90
