Detailed Factors Affecting Filter Bag Service Life 

In addition to the four core factors mentioned earlier, the service life of filter bags is also affected by three supplementary factors that are easily overlooked, which directly determine the stability of bag performance:

1. Filter bag quality: 

The weaving density, thickness, and processing technology of the filter bag affect its durability. Poor weaving density leads to rapid dust penetration and wear; insufficient thickness reduces tensile strength; shoddy sewing (e.g., loose seams) causes early damage at the bag mouth.

2. Pre-treatment effect: 

If the pre-treatment device (cyclone, sedimentation chamber) fails to remove large-particle and corrosive dust, these impurities will directly impact and corrode the filter bag, accelerating damage. For example, large-particle dust will scratch the bag surface, and corrosive dust will degrade the fiber material.

3. Operator operation level:

 Incorrect operation (e.g., improper start-up/shutdown, incorrect adjustment of cleaning parameters) shortens bag life. For example, starting the dust collector without pre-cooling (for high-temperature gas) burns the filter bag; excessive cleaning pressure breaks the bag surface.

To extend service life, in addition to standard maintenance, it is necessary to select high-quality filter bags, ensure the normal operation of pre-treatment devices, and train operators to master standard operation procedures.
