After the QMC-I pulse bag filter starts operating, the dusty gas enters the filter bag chamber through the inlet, and is filtered by the dust removal bag and directly discharged into the atmosphere through the clean air chamber or discharged into the atmosphere through the chimney. The pulse bag filter in dust collectors, also known as filter dust collectors, is a type of dry dust removal equipment in factory workshops. It relies on bag filter elements made of fiber textiles to capture solid particulate matter in dusty gases. The dust removal effect and results are very satisfactory.

The operating principle of QMC-I pulse bag filter:

When dust or dust particles are filtered through the filter cloth fibers, they are intercepted by the machine according to inertia and fiber contact. These polluting dust particles are collected by the filter bag and then swept into the ash hopper through the dust cleaning equipment. They are collected outside the dust collector by the ash removal system. The design of PLC controlled dust cleaning and fault alarm is user-friendly, reducing the labor intensity of workers and shortening maintenance time.

The QMC-I pulse bag filter body is divided into several box areas, with 32, 64, 96 filter bags in each box. There is a lifting valve driven by a cylinder on the outlet pipe of each box. When the pulse bag filter is filtering dusty gas, the dust cleaning controller will send a signal. The lift valve of each chamber begins to close and cut off the filtered airflow, and then the pulse valve of the pulse bag filter chamber opens, injecting compressed air greater than 0.4 MPa into the clean air chamber to remove the dust on the filter bag. After this action is completed, the lift valve will reopen, allowing the chamber to resume filtering work, and complete all dust cleaning actions one by one according to the above procedure.

The QMC-I pulse bag filter adopts a separate box room for dust cleaning. During dust cleaning, each box is isolated and rotated The pulse and cleaning cycle of each compartment are automatically and continuously carried out by the cleaning program controller according to the pre-set program, thereby ensuring the effectiveness of compressed air cleaning. The entire design of the pulse bag filter box adopts the structure of the outlet main pipe, and the ash hopper can be extended below the main pipe, allowing the incoming dusty flue gas to directly enter the expanded ash hopper to achieve the effect of pre dust removal So the QMC type pulse bag filter can not only handle general concentration dusty gases, but also handle high concentration dusty gases.
