我厂职工宿舍区的一台2吨链条快装炉,运行时产生强烈的振动和噪声。据测定主要噪声源鼓风机和引风机附近噪声级为91分贝(A),工人操作处为 90分贝(A),职工宿舍内平均噪声级为 72.5分贝(A)。为了保护职工健康,采取了消声、减振、隔声、除尘等综合治理措施(见图1)。 引风机型号为Y I plant workers quarters area of ​​a 2 tons of fast chain furnace, run-time produce strong vibration and noise. It was determined that the noise level near the main noise source blower and induced draft fan was 91 dB (A), that at the operator’s operation was 90 dB (A) and that of the staff quarters was 72.5 dB (A). In order to protect the health of workers, taken comprehensive measures to eliminate noise, vibration damping, sound insulation, dust removal and other measures (see Figure 1).
