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(tǒng)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。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
我袋式除塵器應用技術的水平有很大提高，袋式除塵器在我各行業(yè)已經得到廣泛的應用。在鋼鐵、有色冶金、建材、化工行業(yè)的爐窯煙氣凈化中，遇到的各種復雜環(huán)境和不利因素，都被克，袋式除塵技術的應用領域不斷擴大。

把粉塵從煙氣中分離出來的設備叫除塵器或除塵設備。除塵器的能用可處理的氣量、氣通過除塵器時的阻力損失和除塵效率來表達。同時，除塵器的價格、運行和維護費用、使用壽命長短和操作管理的難易也是慮其能的重要因素。除塵器是鍋爐及工業(yè)生產中常用的設施。
袋式除塵器結構要由部箱、中部箱、下部箱（灰斗）、清灰系統(tǒng)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(tǒng)對袋式除塵器起著決定的作用。為此，清灰方法是區(qū)分袋式除塵器的特之，也是袋式除塵器運行中重要的環(huán)。
