一、固安飞越除尘布袋的清洗：
1、清灰：采用高频振动、将进入除尘布袋表面的较大的灰尘粒子尽量清除、并不会对纤维的缠结牢度产生影响、保持滤袋良好的耐剥离性。
2、化学实验处理：提取布袋样品、采用专业仪器化验检测滤袋油污成分、从而选用相适应的洗涤原料、最大限度的洗净滤袋而又不对滤袋造成任何损害。
3、清洗：选用合适的洗涤原料并严格配比、低温水清洗、水流均匀、强度适中、对除尘布袋没有机械损伤。

6、检测：采用仪器对清洗后的滤袋进行物理指标检测、确保清洗质量达到要求，经过以上工序的处理、清洗后的除尘布袋完全可以达到使用要求。
二、除尘布袋除尘效果的优劣与多种因素有关，但主要取决于滤料.除尘布袋滤料就是合成纤维、天然纤维或玻璃纤维织成的布或毡。根据除尘器的设计需要再把布或毡缝成圆筒或扁平形滤袋。根据烟气性质，选择出适合于应用条件的滤料。通常，在烟气温度低于120℃，要求滤料具有耐酸性和耐久性的情况下，常选用涤纶绒布和涤纶针刺毡；在处理高温烟气（<250℃）时，主要选用石墨化玻璃丝布；在某些特殊情况下，选用炭素纤维滤料等.除尘布袋除尘的工作机理是含尘烟气通过过滤材料，尘粒被过滤下来，过滤材料捕集粗粒粉尘主要靠惯性碰撞作用，捕集细粒粉尘主要靠扩散和筛分作用。滤料的粉尘层也有一定的过滤作用。

The pros and cons of the dust bag dust effects related to a variety of factors, but mainly depends on the filter. Dust bag filter material is synthetic fiber, natural fiber or glass fiber woven into cloth or felt. According to the the precipitator design of need and then cloth or felt sewn into a cylinder or flat shaped bag. Gas properties, select a filter suitable for application conditions. Typically, the flue gas temperature is below 120 ° C, the filter case with acid resistance and durability, and are often used in polyester flannel and polyester needle felt; temperature flue gas treatment (<250 ℃), the main choice of graphitization glass fiber cloth; in some special cases, the choice of carbon fiber filter. working mechanism of the dust bag dust dust flue gas through the filter material, the dust particles are filtered down, filter material trapping coarse dust depends mainly on the role of inertial impaction , trapping fine particles the dust mainly by diffusion and sieving effect. Filter dust layer also has a certain role in the filtering.
