分散式除尘器，每个除尘系统有单独的除尘器，分散式除尘器可以充分利用高层厂房的某个偏角，将回收的粉尘直接回到生产系统中。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                

简易袋式除尘器主要是依靠粉尘粒自重或风机启动、停止时滤袋的变形，而使粉尘层脱落淸灰，也有利用空气振动来淸灰的。淸灰操作只能在产尘装置停止工作后进行。手动振动机构进行清灰的袋式除尘器，滤袋下部固定在花板上，上部吊挂在水平框架上并与手柄机构相连，含尘气体由下部进入除尘器，通过花板分配到各滤袋内部，经净化后有上部排出。清灰时，通过手摇振动机构，是上部吊挂滤袋的框架作水平往复运动，使袋上粉尘脱落至灰斗中。
