The main failures and avoiding methods of the bag filter

浏览 Author Admin Browse Published 19/01/03

The main failures and avoidance methods of the bag filter :

1. Burning: The reason for the burning of the dust collector bag is mainly due to the insufficient thickness of the initial layer on the surface of the dust collector bag, and the temperature of the flue gas is too high.

2. Abrasion: The abrasion dust bag mainly occurs in the middle of the dust collector, and on a single dust bag, it mainly occurs within 1 meter from the outlet.

3. The distance between the dust bag is too small, the cage bone is bent, etc., it is easy to cause wear between the bags.

4. When there is a hole or burr in the weld of the cage, or the rough surface caused by corrosion, it will also accelerate the wear of the bag.

5. Venturi tube or impulse tube is not aligned properly with the bag, it is easy for the air jet from the blow pipe to directly scour the upper part of the bag and cause wear.

6. Excessive filtration air speed will cause the initial dust layer to break up and the dust to impact the bag and cause excessive wear. If the number of cleaning of the bag is too high at this time, the fabric of the bag may be loosened and the wear of the bag will be accelerated.
