Working principle: When in use, the user uses the universal wheel 8 to move the device body 1 to the required place. If it is necessary to control the dust, the user adds water to the water tank 16 through the water filling port 15, and then presses the first water pump start button. 28, start the first water pump 32, draw the water in the water tank 16 to the fixed nozzle 17 through the rigid water pipe 26, and then spray the drawn water obliquely upward by the first nozzle hole 27 opened on the side of the fixed nozzle 17, to the high place. The dust is treated. If there is an area with a serious dust concentration, the user can press the second water pump start button 30 to start the second water pump 32, and the water in the water tank 16 is drawn to the movable nozzle 13 through the flexible water pipe 14. The second nozzle hole 29 opened on the surface of the movable nozzle sprays the drawn water, and the user can spray the movable nozzle 13 in different directions by holding the flexible water pipe 14, which can effectively control the area with serious dust concentration, while the lower part can spray the water in different directions. The fugitive dust is treated by the cyclone 19, and the induced draft fan 20 introduces the fugitive dust into the air inlet pipe 21, and the fugitive dust enters the cylinder 23 and the cone 24 through the air inlet pipe 21. Under the action, the dust in the dust will fall into the collection box 25, and the air containing no or very little dust will be discharged through the air outlet pipe 22, and then the clean air will be discharged to the cyclone separator placement box 11 through the air diffuser 12.
