袋式除塵器是種干式濾塵裝置。濾料使用段時間后，由于篩濾、碰撞、滯留、擴散、靜電等效應，濾袋表面積聚了層粉塵，這層粉塵稱為初層，在此以后的運動過程中，初層成了濾料的要過濾層，依靠初層的作用，網孔較大的濾料也能獲得較高的過濾效率。隨著粉塵在濾料表面的積聚，除塵器的效率和阻力都相應的增加，當濾料兩側的壓力差很大時，把有些已附著在濾料的細小塵粒擠壓過去，使除塵器效率下降。另外，除塵器的阻力過高使除塵系統的風量顯著下降。因此，除塵器的阻力達到定數值后，要及時清灰。清灰時不能破壞初層，以免效率下降。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
袋式除塵器結構要由部箱、中部箱、下部箱（灰斗）、清灰系統和排灰機構等部分組成。

袋式除塵器能的好壞，除了正確選擇濾袋材料外，清灰系統對袋式除塵器起著決定的作用。為此，清灰方法是區分袋式除塵器的特之，也是袋式除塵器運行中重要的環。
