高炉槽下原料过筛,带来槽下粉尘飞扬,环境污染十分厉害,严重影响工人健康。天铁有4座550m~3高炉,1984年槽下采用了烧结矿过筛,槽下除尘未同时配上,直到1986年才在4号高炉上自行设计安装了槽下除尘,于1987年5月建成投入运行,运行情况良好,今将主要情况介绍于下。高炉槽下四周空地很少,对设置除尘装置较为困难,经过设备选型比较,确定采用某机械厂生产的LDB X/I—650立式除尘器。该器的优点是占地少,过滤面积大,结
The material under the blast furnace tank is screened, resulting in dust flying under the tank. The environmental pollution is very serious and seriously affects the workers’ health. Tiantie has 4 550m ~ 3 blast furnaces, and the sinter was used to sift it under the trough in 1984. The dust was not added to the trough at the same time. It was not until 1986 that it was designed and installed on the No.4 blast furnace. In 1987, Completion of the month put into operation, operating in good condition, the main situation will be introduced below. Blast furnace groove around the little space, the installation of dust removal device is more difficult, after the selection of equipment comparison, to determine the use of a mechanical plant production LDB X / I-650 vertical dust collector. The advantages of this device is small footprint, filter area, knot
