The main reasons for damage to dust filter bags are generally as follows:
1、 Filter wind speed
The high filtering wind speed of the bag filter is the main reason for the damage of the dust removal filter bag. In recent years, some units have blindly reduced equipment costs and increased profits by increasing the filtration wind speed when designing bag filters. Although there is no obvious response from users in a short period of time, it greatly shortens the service life of filter bags. In this way, not only does it not save customers money, but it also brings a significant economic burden and wastes time.
2、 Dust medium
The choice of bag fabric for dust collectors depends on the nature of the dust, taking into account whether the dust contains acidic, alkaline, or highly corrosive substances. Select the appropriate filter material based on the nature of the dust, so that the filter bag can absorb the dust normally without affecting its service life.
3、 Usage temperature
The correct selection of dust removal filter bags suitable for the corresponding dust temperature is the key to filter bags. If the temperature is too high, the selected dust removal filter bag may exceed the normal operating temperature, which can shorten the service life of the filter bag, and in severe cases, it may burn out in a short period of time. Therefore, when selecting filter bags, it is necessary to determine and calculate the inlet temperature of the dust collector before selecting the corresponding dust removal filter bag.
4、 Product Quality
The processing of cloth bags is particularly important. In recent years, some small manufacturers have adopted small sewing machines as processing equipment, and used inferior thread as raw materials during processing, resulting in fake and fake products, and their processing level is far behind. Causing the filter bag to develop issues such as loose threads, cracks, and bottom drops shortly after use. Although a slightly smaller bag size can still be used, after adsorbing dust with a higher specific gravity, the bag will fall off after a period of use.
