[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a self-priming dust purification device, including a housing 1. A dust collector 2 is fixedly connected to the front side of the inner wall of the housing 1. A filter cylinder 21 is provided inside the dust collector 2. A dust collection trough 22 is provided below the dust collector 2. The bottom wall of the filter cylinder 21 is connected to the dust collection trough 22 through a dust collection trough 26. A spray cylinder 3 is fixedly connected to the middle of the inner wall of the housing 1. The dust collector 2 and the spray cylinder 3 are connected through a smoke conveying pipe 36. A sedimentation chamber 32 is provided below the spray cylinder 3. The interior of the spray cylinder 3 is connected to the interior of the sedimentation chamber 32. A sterilization chamber 4 is opened on the rear side of the inner wall of the housing 1. The spray cylinder 3 and the sterilization chamber 4 are connected through a connecting pipe 41. A water storage chamber 31 is provided below the sterilization chamber 4. A smoke inlet pipe 5 is fixedly sleeved on the front top of the housing 1. The inside of the smoke inlet pipe 5 is connected to the inside of the filter cartridge 21. A fan 6 is installed in the groove of the inner wall of the smoke inlet pipe 5. A rotating rod 24 is fixedly sleeved inside the fan 6. The bottom end of the rotating rod 24 is rotatably connected to the top end of the cross plate 25. The end of the cross plate 25 is fixedly connected to the inner wall of the dust collection trough 26. A scraper 27 is fixedly connected to the surface of the rotating rod 24. One side of the scraper 27 is in contact with the inner surface of the filter cartridge 21. A dust collection drawer 23 is slidably connected to the inner wall of the dust collection trough 22. A water pump 33 is fixedly installed on the inner wall of the water storage chamber 31. A water supply pipe 34 is fixedly connected to the output end of the water pump 33. One end of the water supply pipe 34 passes through the inner wall of the water storage chamber 31 and is fixedly connected to a water distribution tank 35. The water distribution tank 35 is located inside the spray cylinder 3 and above. Several water mist nozzles are threadedly connected to the bottom end of the water distribution tank 35. Several baffles 42 are fixedly connected to the inner wall of the sterilization chamber 4, and several ultraviolet lamps 43 are also fixedly installed on the inner wall of the sterilization chamber 4. An air outlet slot 7 is provided on the rear side of the housing 1. A magnetic suction slot is provided inside the air outlet slot 7. An activated carbon plate 8 is slidably connected to the inner wall of the magnetic suction slot. A magnetic suction head is provided at one end of the activated carbon plate 8.

[0019] During use, the fan 6 is started, allowing the dust-laden flue gas to enter the filter cylinder 21 inside the device through the flue gas inlet pipe 5. When the flue gas passes through the filter cylinder 21, larger dust particles are intercepted by the filter screen and adhere to the inner wall of the filter cylinder 21. While the fan 6 is rotating, the scraper 27 is rotated through the rotating rod 24 to continuously scrape off the dust accumulated on the inner wall of the filter cylinder 21. The dust falls into the dust collection trough 22 below through the dust collection trough 26 and is stored in the dust collection drawer 23. After preliminary filtration, the flue gas enters the spray cylinder 3 through the flue pipe 36. The water pump 33 is started, and the water pump 33 transports the water inside the water storage chamber 31 to the water distribution tank 35 above the spray cylinder 3 through the water supply pipe 34. Fine water mist is sprayed out through the water mist nozzle at the bottom of the water distribution tank 35, which mixes thoroughly with the flue gas, captures the fine dust and harmful particles remaining in the flue gas, forms wastewater droplets, and falls into the sedimentation chamber 32 below the spray cylinder 3 by gravity, where the dust settles. After washing, the flue gas enters the sterilization chamber 4 through the connecting pipe 41. The baffle plate 42 in the chamber guides the airflow in an "S" shaped path to prolong the residence time. The ultraviolet lamp 43 continuously irradiates the air, destroying the DNA structure of bacteria, viruses and other microorganisms in the flue gas, thereby achieving sterilization and disinfection. After sterilization, the airflow flows to the outside through the air outlet slot 7. During the flow, the sterilized airflow first passes through the activated carbon plate 8, which adsorbs residual odors, volatile organic compounds (VOCs), and fine particles, further purifying the air. Finally, the clean air that meets the standards is discharged from the device through the air outlet slot 7, completing the entire purification process.

[0020] Reference Figures 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a through pipe 37 is fixedly connected between the water storage chamber 31 and the sedimentation chamber 32. A hemispherical filter head 38 is fixedly connected to one end of the through pipe 37 extending to the sedimentation chamber 32. A cleaning door 39 is movably connected to one side of the sedimentation chamber 32.

[0021] During use, the wastewater after washing the dust in the spray cylinder 3 falls into the sedimentation chamber 32 below. Larger dust particles settle to the bottom, and the upper wastewater flows into the water storage chamber 31 through the hemispherical filter head 38 at one end of the pipe 37, realizing the recycling of water resources. When there is a lot of dust accumulation at the bottom of the sedimentation chamber 32, the side cleaning door 39 can be opened to directly clean the sediment, avoiding clogging of the pipe 37 or affecting the water quality.

[0022] Reference Figures 1-4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a handrail is fixedly connected to the top rear side of the box 1, and movable wheels are fixedly installed at the four corners of the bottom of the box 1.

[0023] During use, the four corners of the bottom of the box 1 support the device to move flexibly, making it easy to deploy quickly in different work areas and adapt to the purification needs of multiple scenarios; the handrail on the top rear side of the box 1 provides a gripping point when carrying or moving the device, and together with the moving wheels, it can be easily pushed or turned by a single person.
