Bag house dust bag is the most important part, but also the most easy to wear bag house parts when precipitators work, in order to prevent damage to the bags of a certain impact on the bag house work place in bag damage should have some treatment. In general, the dust bag is gradually worn, the main cause of wear of the grinding force is dust, filter deterioration and chemical corrosion caused by high temperature, dust when grinding very strong, the bottom of the bag and wear the most serious , causes an increase in system capacity can be increased filtration rate accelerated wear. ESP can not use a damaged dust bag work, otherwise it will accelerate precipitator scrapped. When the individual dust bag breakage occurs when a small area, you can use the old dust bag or the same material will be used on new cloth patch the hole, fill the hole method is to use a silicone rubber compound for bonding, as long as the temperature of the adhesive chemical properties and process conditions can be adapted. When most of the damage to the bag, should be completely replaced (when filter after long-term work, accumulated in the filter layer of fine dust it reduces permeability, while the system affect the amount of wind, although not damaged, it should be completely replaced) replace dust bag is best when the work stopped, this time should be cleaning unit is switched off, open the top of Manhole, will removable bag, disassembly, first remove the bag cage, and then the bag catchy coil shape into a concave, pulled up the bag, before installing the new bag, the dust should be spent on the clean plate hole.
