我厂从事铸钢件的生产,现有电弧炉两座。在电弧炉冶炼过程中,排放出大量烟尘,每炼一吨钢可产生5—8公斤,经测定操作现场的粉尘浓度达17.6mg/m~3,污染周围环境,对天车工、炼钢工及与之相毗邻岗位作业的工人危害极大。1974年初,我们在一座苏式五吨电弧炉上安设了四台DMC型脉冲袋式除尘器,采取两台串联两台并联的方式,总过滤面积为360平方米。投产近十
I plant engaged in the production of cast steel, the existing two arc furnace. In the electric arc furnace smelting process, a large amount of smoke and dust emissions, each refining a ton of steel can produce 5-8 kg, the measured operating site concentration of dust up to 17.6mg / m ~ 3, polluting the surrounding environment, the crane workers, steelworks And the workers who work adjacent to them are extremely harmful. In early 1974, we installed four DMC-type pulse bag filters on a Soviet five-ton electric arc furnace, using two tandem units in series with a total filtration area of 360 square meters. Put into operation nearly ten
