[0030] A cleaning rod 9 is connected to the bottom of the driving rod 4, and a filter screen 10 is arranged below the cleaning rod 9. A temporary storage block 11 is connected to the left side of the filter screen 10. Impurities are concentrated and processed through the temporary storage block 11 for easy cleaning. A stirring rod 13 is connected to the bottom of the driving rod 4, and a water tank 14 is arranged below the stirring rod 13. Water flow is stored through the water tank 14 for easy use. A circulation pipe 15 is connected to the right side of the water tank 14, and a nozzle 16 is arranged below the circulation pipe 15. The nozzle 16 is used to spray water to reduce dust.

[0031] See the attached drawings in the specification Figure 1-4 An air outlet 12 is also provided on the left side of the device body 1, and nozzles 16 are evenly and equidistantly distributed on the top of the device body 1. The nozzles 16 are connected to the water tank 14 through a circulation pipe 15. The circulation pipe 15 cooperates with the nozzles 16 to realize the recycling of water.

[0032] See the attached drawings in the specification Figure 1-4 Connecting rods 5 are evenly and equidistantly distributed on the outside of the center of the driving rod 4, and inclined plates 6 are evenly and equidistantly distributed on the outside of the connecting rod 5. The inclined plates 6 and the connecting rod 5 are installed in an integrated manner. The connecting rod 5 cooperates with the inclined plates 6 to allow air to circulate, so that dust and water are mixed.

[0033] See the attached drawings in the specification Figure 1-4 The baffle 7 is integrated with the device body 1. Spiral tubes 8 are symmetrically distributed on both sides of the baffle 7. The spiral tubes 8 penetrate the baffle 7 in a spiral state. The baffle 7 cooperates with the spiral tubes 8 to mix the water flow and the smoke and dust to ensure the dust removal effect.

[0034] See the attached drawings in the specification Figure 1-4 The cleaning rod 9 and the driving rod 4 are installed in an integrated manner. The cleaning rod 9 fits tightly against the filter screen 10. The filter screen 10 and the temporary storage block 11 are installed in an integrated manner.

[0036] Working principle: When in use, first, the flue gas enters the interior of the device body 1 through the air inlet 2, and the water pump of the circulation pipe 15 and the switch of the drive motor 3 are turned on. The circulation pipe 15 draws water through the water tank 14 and then discharges it through the nozzle 16 to remove dust from the flue gas. At the same time, the drive rod 4 is driven by the drive motor 3 to rotate, and the inclined plate 6 and the connecting rod 5 rotate together with the drive rod 4, so that the water flow and the flue gas are fully mixed. Then the water flow and the flue gas fall above the filter screen 10 through the spiral tube 8, and are fully mixed when passing through the spiral tube 8, ensuring that the dust is adsorbed by the water flow. Finally, the flue gas is discharged from the air outlet 12;

[0037] As mentioned above, after the smoke is discharged, the water flow is filtered by the filter 10, and the impurities remain above the filter 10. At the same time, the cleaning rod 9 and the stirring rod 13 rotate together with the driving rod 4. The cleaning rod 9 pushes the impurities into the temporary storage block 11. The staff can remove the impurities by opening the opening and closing door. The stirring rod 13 drives the water flow to rotate, accelerates the heat dissipation, and finally opens the valve port to let the water flow into the water tank 14.
