[0029] The working principle of the present utility model is:

[0030] Dust-containing gas enters the filtration and dust collection chamber from the air inlet 4. The sudden expansion of the air flow cross-section causes dust particles with large diameters to settle into the ash hopper 21 under the action of gravity and inertia. Dust with small particle sizes and low densities is deposited on the surface of the filter cartridge 3 under the combined effects of Brownian diffusion and sieving. The filtered air enters the inner cavity of the filter cartridge 3. Under the action of the fan 11, the air enters the air duct 13 and is then discharged from the air outlet of the fan 11 and finally discharged to the outside of the cabinet 1 through the air outlet 12;

[0031] As the thickness of the dust adhering to the surface of the filter cartridge increases, the resistance rises accordingly. When the resistance reaches the set value, the control system activates the pulse valve 67. The compressed air in the air storage tank 66 expands rapidly and surges into the inner cavity of the filter cartridge 3, causing the filter cartridge 3 to expand and deform to generate vibration, peeling off the dust adhering to the surface of the filter cartridge 3 and falling into the ash hopper 21. Manually pull out the baffle plate 22 to make the dust in the ash hopper 21 fall into the ash collection bucket 32. After the dust cleaning is completed, close the pulse valve 61 to restore the filtration state, and manually disassemble the ash collection bucket 32 to clean the internal dust.
