冶金部建筑研究总院环保所噪声控制研究室近几年在开发高炉消声系列产品过程中,研制出GLX型高炉放风消声器,经模拟试验后,用于国内高炉生产,其中在攀钢1号和2号高炉(炉容为1000m~3和1200m~3)的放风消声器。最近进行了现场验收,由攀钢劳卫所测定冷风放风时消声器出口噪声降至81dB(A),消声量达50dB(A)。该消声器于1985年和1986年先后投入使用,经受了考验,满足了生产工艺要求,取得了显著效
The noise control laboratory of the Environmental Protection Institute of the Ministry of Metallurgical Construction Research Institute has developed a GLX type blast furnace muffler in the course of the development of blast furnace anechoic products in recent years. After the simulation test, it was used for domestic blast furnace production, including Panzhihua Iron and Steel No.1. Blower muffler for No. 2 blast furnaces (capacity 1000m~3 and 1200m~3). Recently, on-site acceptance was carried out. The noise from the muffler at the outlet of cool air when measured by the Panzhihua Iron and Steel Institute fell to 81dB (A), and the noise reduction reached 50dB (A). The muffler has been put into use in 1985 and 1986, has stood the test, has met the production process requirements, and has achieved remarkable results.
