The main reasons for the damage of dust collector filter bags are generally as follows:


1. Dust medium


The choice of the filter bag of the dust collector depends on the dust properties of the dust, and it is necessary to consider whether the dust contains acid, alkali or strong corrosive substances. Select the suitable filter material according to the nature of the dust, so that the filter bag can absorb the dust normally without affecting its service life.


2. Filter wind speed


The filter wind speed of the bag filter is too high, which is the main reason for the damage of the filter bag. In recent years, some units have blindly reduced equipment costs and increased profits. When designing a bag filter, the filter wind speed was increased. In a short period of time, there was no obvious response from users, but the service life of the filter bag was shortened. In this way, instead of saving money for customers, it brings a very large economic burden and wastes time.


3. Use temperature


The key to filter bags is the correct selection of dust collector bags suitable for the corresponding dust temperature. If the temperature is too high, the selected filter bag will exceed the normal operating temperature, and the filter bag will shorten the service life in light, and will burn out in a short time in serious cases. Therefore, when selecting the filter bag, the temperature of the dust collector should be measured and calculated, and the corresponding dust collector cloth bag should be selected.


The pros and cons of the dust removal effect of general dust collectors are related to many factors, but mainly depends on the protective cover of the bag, which is a cloth or felt woven from synthetic fibers, fibers or glass fibers. The protective cover can be made of cotton wool fiber, glass fiber or various chemical fibers through weaving (or acupuncture) into a filter material, and then sewn into a vertical hanging filter bag. Different filter materials should be selected for different occasions. Sew the cloth or felt into a ball-type dust collector bag as needed.
