[0002] During the waste incineration process, the exhaust flue gas needs to be filtered, and the filtering dust removal device needs to use a filter bag. The surface of the polytetrafluoroethylene (PTFE) film is smooth and resistant to chemicals. It is laminated to the surface of various needle-punched felts to play the role of a disposable dust layer, which traps all the dust on the surface of the membrane to achieve surface filtration. The existing filter bags have been used for a long time and need to be replaced. The replacement operation is more troublesome and there is a lack of a suitable quick replacement mechanism.
