近年来,国外钢铁厂大力推广使用干式烟尘净化设备。采用干式净化设备不产生污水,同时又能回收捕收物。干式净化设备的特点是规格尺寸小、营运费低。目前,国外钢铁厂在大多数的情况下采用电除尘器,布袋除尘器及分层颗粒过滤捕集在高温冶金工艺过程中形成的细粒 In recent years, foreign steel mills vigorously promote the use of dry fume purification equipment. The use of dry cleaning equipment does not produce sewage, while recovering the collector. Dry purification equipment is characterized by small size, low operating costs. At present, foreign steel mills in most cases the use of electrostatic precipitator, bag filter and stratified particle filtration trapped in the pyrometallurgical process of the formation of fine particles
