袋式除尘器是种干式滤尘装置。滤料使用段时间后，由于筛滤、碰撞、滞留、扩散、静电等效应，滤袋表面积聚了层粉尘，这层粉尘称为初层，在此以后的运动过程中，初层成了滤料的要过滤层，依靠初层的作用，网孔较大的滤料也能获得较高的过滤效率。随着粉尘在滤料表面的积聚，除尘器的效率和阻力都相应的增加，当滤料两侧的压力差很大时，把有些已附着在滤料的细小尘粒挤压过去，使除尘器效率下降。另外，除尘器的阻力过高使除尘系统的风量显著下降。因此，除尘器的阻力达到定数值后，要及时清灰。清灰时不能破坏初层，以免效率下降。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
我袋式除尘器应用技术的水平有很大提高，袋式除尘器在我各行业已经得到广泛的应用。在钢铁、有色冶金、建材、化工行业的炉窑烟气净化中，遇到的各种复杂环境和不利因素，都被克，袋式除尘技术的应用领域不断扩大。

把粉尘从烟气中分离出来的设备叫除尘器或除尘设备。除尘器的能用可处理的气量、气通过除尘器时的阻力损失和除尘效率来表达。同时，除尘器的价格、运行和维护费用、使用寿命长短和操作管理的难易也是虑其能的重要因素。除尘器是锅炉及工业生产中常用的设施。
袋式除尘器结构要由部箱、中部箱、下部箱（灰斗）、清灰系统和排灰机构等部分组成。

袋式除尘器能的好坏，除了正确选择滤袋材料外，清灰系统对袋式除尘器起着决定的作用。为此，清灰方法是区分袋式除尘器的特之，也是袋式除尘器运行中重要的环。
