What should be done for the quality inspection of the dust filter bag?
The working mechanism of a filter bag dust precipitator is dust containing gas through the filter material, the dust is filtered, the filter material to trap coarse dust mainly depends on the inertial collision, collecting fine dust mainly by diffusion and sieving effect.
The advantages and disadvantages of the filter bag are related to many factors, but mainly depend on the filter material.Dust filter bag filter is a synthetic fiber fabric or felt natural fiber or glass fiber woven, according to the need to design the dust collector of the cloth or felt sewn into a cylinder or a flat shaped bag, according to the character of flue gas, selection of filter material, suitable for application in the premise of usually smoke temperature lower than 120 DEG C requirements the filter has acid resistance and durability of the case, often used in polyester velvet and polyester felt, in the treatment of high temperature gas (<250 C), using graphite glass cloth, in some special cases, using carbon fiber filter etc..
Filter dust layer also has a certain filtering effect, dust filter bag cleaning. Because of the use of the resulting abrasion, holes and other damaged filter bags for repair, to ensure a high rate of reuse.The instrument is used to check the cleaning bag to ensure the cleaning quality. Through the processing of the above process, the filter bag after cleaning can completely meet the application requirements
