高炉煤气减压阀组是炼铁生产中的重要设备之一,它在工作时,产生强烈的气流噪声,在减压阀组出口处管道外测量,声压级达130dB(A)左右,成为炼铁厂的主要噪声污染源之一。噪声除了污染减压阀组周围地区外,还能沿管道传播,污染煤气管线附近地区。我国在1986年以前对该噪声未加治理,1986年开始,冶金部建筑研究总院在消化移植宝钢一期消声器的基础上,开展了该噪声治理的研究工作,经过几年的努力,研制出了GMT型煤气减压阀组消声器系列,经唐钢和宣钢一年多的使用证明,设备性能可靠,消声效果很
Blast furnace gas pressure reducing valve group is one of the most important equipment in ironmaking. When working, it produces strong air flow noise, which is measured outside the pipeline at the outlet of the reducing valve group. The sound pressure level reaches about 130dB (A) Ironworks one of the main sources of noise pollution. In addition to pollution noise around the valve area, but also along the pipeline spread, polluting the gas pipeline near the area. China did not deal with the noise before 1986, and from 1986, the Research Institute of Architecture and Research of the Ministry of Metallurgical Construction carried out the research work of noise control on the basis of digesting Baosteel Phase I muffler. After several years of hard work, The GMT series of gas valve muffler series, the steel and Xuanhua more than a year of the use of steel that equipment reliability, noise effect is very
