1、除尘布袋的质量
简易布袋除尘器依靠粉尘自重或人工拍料使其脱落，在清灰过程中对除尘布袋几无损伤，可采用质量一般，价格低廉的布作为除尘滤袋。Simple bag filter depends on dust weight or material artificial shoot it off, dust filter bag in the cleaning process, a few non-injury can be the general quality of cheap cloth as a dust filter bag。
2、过滤时间的长短
随着过滤时间的增加，除尘滤袋表面的集尘量增加，压力损伯也不断增加，在实际操作中，由于除尘滤袋压力损失的增加，使系统中的气量减少，压力损失则由于气量减少而降低至。因此，这个压力损失的极限是气量趋于0时的风机压头，在不同的含尘气体浓度和负荷下，随着过滤时间的增加，其浓度大的压力损失增加得快，负荷 大的压力损失也增加得快。 With increasing filtration time, the increase in the amount of the surface of the dust filter bag dust, the pressure loss JOB also increasing, in the actual operation, since the increase in pressure loss in the dust filter bag, so that the quantity of gas in the system to reduce the pressure loss due to gasreduced reduced to. Therefore, the limit of the pressure loss is the pressure head of the fan in the gas tends to 0, in different dusty gas concentrations and under a load, to increase faster with increasing filtration time, the concentration of a large pressure loss, a large pressure load The loss also increased quickly.
3、清灰方式
简易布袋除尘器清灰方式有除尘布袋自行清灰和人工拍打清灰。除尘布袋自行清灰于只依靠附着于除尘滤袋表面上粉尘层自行脱落，所以粉尘下落量不大，压力损失只降低。人工拍打清灰，除尘滤袋压力损失下降一般为300pa,但除尘效率在重新操作的短时间内有所下降。Easy bag filter cleaning methods have the dust bag self-cleaning and manual tapping cleaning. Dust bag self-cleaning only rely attached to the layer of dust on the surface of dust filter bag off on their own, so the dust whereabouts not only reduce the pressure loss. Manual tapping ash, dust filter bag pressure loss dropped 300pa, collection efficiency decline in re-operation within a short time.
