袋式除塵器是種干式濾塵裝置。濾料使用段時(shí)間后，由于篩濾、碰撞、滯留、擴(kuò)散、靜電等效應(yīng)，濾袋表面積聚了層粉塵，這層粉塵稱為初層，在此以后的運(yùn)動(dòng)過(guò)程中，初層成了濾料的要過(guò)濾層，依靠初層的作用，網(wǎng)孔較大的濾料也能獲得較高的過(guò)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(yīng)的增加，當(dāng)濾料兩側(cè)的壓力差很大時(shí)，把有些已附著在濾料的細(xì)小塵粒擠壓過(guò)去，使除塵器效率下降。另外，除塵器的阻力過(guò)高使除塵系統(tǒng)的風(fēng)量顯著下降。因此，除塵器的阻力達(dá)到定數(shù)值后，要及時(shí)清灰。清灰時(shí)不能破壞初層，以免效率下降。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
袋式除塵器結(jié)構(gòu)要由部箱、中部箱、下部箱（灰斗）、清灰系統(tǒng)和排灰機(jī)構(gòu)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(duì)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(yùn)行中重要的環(huán)。
