Vacuum refining waste gas treatment system

The utility model provides a vacuum refining waste gas treatment system. The vacuum refining waste gas treatment system comprises a primary gas cooling dust remover (1), a pipeline (2), a secondary gas cooling dust remover (4), a dust removal filter group (5) and a vacuum pump group (6) which are sequentially connected in series. According to the vacuum refining waste gas treatment system, through rough dust removal of the first-stage gas cooling dust remover and the second-stage gas cooling dust remover and fine dust removal of the dust removal filter, any dust and impurities can be prevented from entering the mechanical vacuum pump, and the vacuum pump is protected to the maximum extent. 本实用新型提供了一种真空精炼废气处理系统，所述真空精炼废气处理系统包括依次串联的一级气体冷却除尘器(1)、管道(2)、二级气体冷却除尘器(4)、除尘过滤器组(5)和真空泵组(6)。该真空精炼废气处理系统通过一级气体冷却除尘器、二级气体冷却除尘器的粗除尘，以及除尘过滤器的细除尘，可避免任何粉尘和杂物进入到机械真空泵内部，做到最大程度保护真空泵。
