Technical Field
[0001] This utility model relates to the field of dust removal device technology, and in particular to a wet dust removal device for air pollution control. Background Technology
[0002] Wet scrubbing devices use atomizing nozzles to spray water into fine droplets, which collide with dust particles in the exhaust gas through inertial collisions, diffusion, interception, agglomeration, and adsorption. This causes the dust to adhere to the water droplets or be wrapped by the water film, forming dust-laden wastewater, thereby achieving gas-solid separation.
[0003] The wet dust removal device disclosed in patent CN221131560U improves dust removal efficiency through stirring blades and atomizing nozzles, but it was found during long-term operation that:
[0004] Dust easily adheres to the inner wall of the dust collector chamber due to centrifugal force, requiring regular manual cleaning, which affects the continuous operation efficiency of the equipment. Furthermore, the atomizing nozzles inside the dust collector chamber are easily clogged by dust and impurities, thus affecting the dust reduction efficiency. Therefore, this application proposes an air pollution control wet dust removal device based on the existing technology to solve the problems mentioned in the background technology.

The bottom end of the discharge pipe 12 is fixedly connected to the collection box 13.
[0021] The working principle of this utility model is as follows: Dust-laden exhaust gas enters the dust collector 1 through the inlet pipe 10 at the rear end of the dust collector 1. The airflow direction is parallel to the axis of the dust collector 1. An external water supply device supplies water to the semi-annular water storage tank 4 through the water supply pipe 5. The water in the water storage tank 4 is evenly sprayed into the dust collector 1 through the spray holes 7 at the top of the dust collector 1, forming a dense water mist that covers the upper space of the dust collector 1. After the drive motor 6 starts, it drives the coaxially mounted rotating shaft 2 to rotate at high speed. The stirring rods 3 at both ends of the rotating shaft 2 rotate with the shaft, forming a strong airflow vortex field inside the dust collector 1. The vortex field forces the exhaust gas and water mist to fully mix in turbulent flow. Dust particles collide with the water mist due to inertial forces, agglomerate, and are adsorbed. The rotating stirring rods 3 drive the airflow to make circular motion, generating centrifugal force, so that the "water- The dust-laden composite is thrown against the cylindrical inner wall of the dust collector 1, forming a dust-laden water flow that slides down the wall. The cleaning bracket 8 at the bottom of the rotating shaft 2 rotates with the shaft, causing the cleaning brush 9 to scrape against the inner wall of the dust collector 1, peeling off the attached dust layer and preventing dust accumulation from affecting airflow distribution. The cleaning brush 9 can also clean the dust clogging inside the spray holes 7, preventing the spray holes 7 from becoming blocked. The clean gas after water mist capture and centrifugal separation is discharged through the exhaust pipe 11 on the left side of the dust collector 1. The dust-laden water flow that slides down the wall and the dust settled at the bottom enter the collection box through the discharge pipe 12. This utility model cleans the spray holes 7 while cleaning the inner wall of the dust collector 1, preventing the spray holes 7 from becoming blocked. Compared with using atomizing nozzles, it is easier to clean.
