Tail gas recovery device for polypropylene production

The utility model discloses a tail gas recovery device for polypropylene production, which is characterized in that a tail gas purification mechanism is arranged for filtering and purifying tail gas, the purified tail gas is guided into a water tank gas filtering mechanism for absorbing water-soluble substances, and then the tail gas is discharged into a condensation mechanism for condensation treatment and recovery of water vapor in the tail gas; a filter bag type filter structure in the tail gas purification mechanism can be pulled out from the interior of the purification box body in a manner of pulling a baffle plate, and a filter plate made of an activated carbon material is exposed after being pulled out, so that the filter plate and a filter bag can be cleaned more conveniently. 本实用新型公开一种聚丙烯生产用尾气回收装置，通过设置有尾气净化机构对尾气进行过滤净化，净化后的尾气导入水箱滤气机构内进行水溶性物质吸收，随后尾气排入冷凝机构内冷凝处理回收其中水汽；尾气净化机构中的滤袋式过滤结构可通过抽拉挡板的方式从净化箱体内部抽离，抽离后活性炭材质的滤板暴露出来，更便于对滤板和滤袋进行清理。
