The subjective reasons for the damage of the dust filter bag

The dust filter bag is an important part of the dust removal efficiency of the bag filter. The cost of replacing the filter bag is also the maintenance cost of the bag filter. Therefore, the service life of the filter bag is related to the operation form and cost of the filter.

Chongxin Dust Removal Equipment Co., Ltd. believes that there are 4 subjective reasons for the damage of dust removal bags:

1. Product quality

The processing of cloth bags is particularly important. In recent years, some small manufacturers have used small sewing machines as processing equipment, and used inferior threads as raw materials during processing, which are fake and real, and the processing level is far behind. So that the filter bag will appear open lines, cracks, loss of bottom and other phenomena in a short time of use. Although the size of the cloth bag is slightly smaller, it can also be used, but after absorbing the dust with a larger specific gravity, the phenomenon of the lost bag will appear after a period of time.

2. Operating temperature

Selecting a dust filter bag that responds appropriately to the dust temperature is the pivot of the filter bag. If the temperature is too high, the selected dust filter bag will exceed the normal operating temperature, the filter bag will shorten the service life, and will be destroyed in a short time. Therefore, when selecting a filter bag, it is necessary to measure and calculate the temperature of the dust collector, and select a corresponding dust filter bag.

3. Filter wind speed

The filter wind speed of the bag filter is too high, which is the main reason for the damage of the dust bag. In recent years, some units have blindly aimed to reduce equipment costs and increase profits. When designing a bag filter, the filter wind speed has been increased. In a short period of time, the user has no obvious response, but the service life of the filter bag is greatly shortened. In this way, instead of saving money for customers, it has brought a huge economic burden and extra time.

4. Dust medium

The choice of the bag cloth for 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 appropriate filter material according to the nature of the dust, so that the filter bag can absorb the dust normally without affecting its service life.


Products are widely used in steel, cement, chemical industry, power plants, road construction, metallurgy, food processing, etc.
