The design and processing of the bag cage should reduce the deformation of the filter bag as much as possible.
Make the combination between the filter bag and the 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 must be combined with the dust removal bag.
20-24 high-temperature-resistant carbon steel bars are generally used for vertical reinforcement of the cage, each bar has a thick of 3.2 mm, the inner ring of the cage is made of a high-temperature carbon steel bar of Φ 4 mm thick, the distance between the first ring of the cage and the bottom of the cage from the bottom of the cage upwards is 50 mm, The distance between the second ring in the cage and the first ring in the cage shall be less than 155 mm and so on, the last ring in the cage shall be held at a distance of 50 mm from the bottom of the upper flange of the cage.
Also, the processing quality requirements of bag cages are very important. Special equipment for the manufacture of rings and spot welding should be used to reduce burrs and maintain verticality.
