The design and processing of bag cage should reduce the warp of filter bag as much as possible
- Make the matching between filter bag and bag cage as appropriate as possible, and it should not be too loose or too tight. Before the bag cage is manufactured in large quantities, it should be matched with the dust removal bag.
- Generally, 20-24 high temperature resistant carbon steel bars are used for the vertical reinforcement of the cage, each bar is Φ 3.2 mm thick, the inner ring of the cage is made of Φ 4 mm thick high temperature resistant carbon steel bar, the distance between the first cage ring and the cage bottom from the cage bottom upward is 50 mm, the distance between the second cage ring and the first cage ring shall be less than 155 mm, and so on, the last cage ring shall be kept at a distance of 50 mm from the top flange bottom of the cage.
- In addition, the processing quality requirements of bag cage are also very important. Special ring making and spot welding equipment should be used to reduce burr and maintain verticality.
