The main reason for the damage of the dust collector bag

First, filter wind speed

The filter wind speed of the bag filter is too high, which is the main reason for the damage of the bag of the dust collector. In recent years, some units have blindly reduced equipment costs and increased profits. When designing bag-type dust collectors, the filtration wind speed is increased, and the user has no obvious reaction in a short time, but the service life of the dust collector bag is greatly shortened. In this way, instead of saving money, the customer has a very large economic burden and wasted time.

Second, the dust medium

The choice of the fabric of the dust collector bag is determined by the dust properties of the dust, taking into account whether the dust contains acid, alkali or corrosive substances. According to the nature of the dust, the filter material suitable for it is selected, so that the filter bag can properly absorb the dust without affecting its service life.

Third, the use temperature

Proper selection of the dust collector bag suitable for the corresponding dust temperature is the key to the filter bag. If the temperature is too high, the selected dust collector bag will exceed the normal use temperature, the filter bag will shorten the service life, and it will burn out in a short time. Therefore, when selecting the filter bag, be sure to calculate the inlet temperature of the precipitator, and select the corresponding dust collector bag.

The advantages and disadvantages of the dust removal effect of the general dust collector bag are related to various factors, but mainly depend on the bag protection cover. The protective cover is a cloth or felt woven from synthetic fiber, natural fiber or glass fiber. The protective cover can be woven (or needled) into a filter material by cotton fiber, glass fiber or various chemical fibers, and then sewn into a vertical hanging filter bag. Different filter materials should be used in different occasions. If necessary, sew the cloth or felt into a ball-type dust collector bag.
