At present, bag dust removal is the main method for large-scale industry to deal with waste gas, and the filter bag is the key part in the operation process of the dust collector. The filter bag is required to be able to filter dust efficiently, be convenient to replace and easy to clean. However, in the process of filtering dust flue gas by the filter bag, when the filtering effect of the middle and upper parts of the filter bag has not been normally exerted, the dust accumulation at the bottom is large, and the filtering effect cannot be fully exerted, resulting in a decrease in air permeability and poor filtering effect. Therefore, it is necessary to remove the filter bag for cleaning every short period of time. During the process of multiple installations and dismountings, the filter bag is prone to damage, which in turn leads to dust leakage, affecting the use effect of the filter bag and reducing the production efficiency. For example, the Chinese invention patent with the patent number CN 114768405 B discloses a special cage provided with a corrugated filter bag and an installation method.
