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 vacu-um 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 inte-grated 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 vac-uum pump are ensured.
