摘　　要：在VD、VOD、RH等真空精炼系统使用干式机械泵系统抽真空时,钢液产生的大量粉尘会随着工艺气体进入真空管道,为保护真空泵,需在机械真空泵前设置除尘器对工艺气体进行除尘。普遍采用在袋式除尘器前加旋风除尘器,造成占地面积大、成本高、运行费用高。文章介绍的除尘器采用旋风布袋一体式的结构形式,分别将这两部分通过两舱的形式安装在一个除尘器里,占地小、成本低。同时通过优化的结构设计,一体式除尘器具有除尘效率高、压损小等特点,维护检修方便快捷,保证了干式机械真空泵长期安全运行。When dry mechanical pump system is used to vacuumize for such vacuum refining systems as VD,VOD and RH,a large amount of dust generated in liquid steel will enter vacuum pipe with process gas.In order to protect vacuum pump,the precipitator needs to be installed in front of mechanical vacuum pump to remove dust in process gas.It is common to add a cyclone dust collector in front of bag filter so that occupied area is large as well as costs and operating costs are high.The precipitator introduced in this article is with the integrated structure of cyclone and bag.These two parts are installed in two compartments mode within one precipitator so that occupied area is small and costs are low.The integrated precipitator is with such characteristics as high dust removal efficiency,small pressure loss as well as convenient and rapid maintenance and repair through optimizing structural design so that long-term safe operations of dry mechanical vacuum pump are ensured.
