PPM gas box pulse bag dust collector; The main body is divided into several box areas, with 32, 64, 96 filter bags in each box. There is a lift valve driven by a cylinder on the outlet pipe on the side of each box. When the dust collector is filtering the dusty gas, the dust cleaning controller will send a signal, and the lift valve of each chamber will start to close and cut off the filtered airflow; Then the pulse valve in the chamber is opened, and compressed air greater than 0.4 MPa is injected 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 PPM gas box pulse bag dust collector 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, thus achieving the effect of compressed air cleaning. The entire box design adopts an outlet main pipe structure, 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 gas box pulse bag filter can not only handle dust containing gases of general concentration, but also handle dust containing gases.

PPM gas box pulse bag dust collector; Installation requirements:

1. The installation of dust collectors should be carried out in accordance with the design drawings and relevant installation specifications.

2. After cleaning, the flange connections (including compressed air pipelines) of the dust collector should be embedded with sealing gaskets on the inside and outside of the screw holes, and then tightened with bolts (there are sealing gaskets on the inside of the screw holes) to prevent air leakage.

3. The sealing gaskets of each inspection door and hole shall be tightly bonded with adhesive, and there shall be no gaps left at the overlap, and they must be diagonally connected without falling off.

4. Special attention should be paid to the handling and parking of filter bags to prevent them from coming into contact or colliding with surrounding hard or sharp objects. It is also prohibited to step on or press heavily to prevent damage.

5. The installation of the filter bag should be closely attached to the hole opening of the flower plate, without leaving any pores, to prevent detachment and air leakage.

6. Before installation, check whether there is any weld detachment in the inlet and outlet ducts, filter chamber, and clean room of the shell. During the installation and welding of various components for disassembly and transportation, special attention should be paid to the sealing of the above chambers and air ducts to prevent air leakage.

7. Each transmission component should be installed correctly, rotate flexibly, and lubricated with oil.

8. If the dust collector is installed outdoors, a rain shelter should be built on top.
