Specific embodiment one:

Please refer to Figures 1-7. The utility model is a wet air curtain dust collector, and its structure includes a bellows 1, a plurality of first dust and water collectors 2, a plurality of second dust and water collectors 3, a sprayer 4 and a water collector 5. The bellows 1 includes an air inlet connection section 11, a flared pipe section 12 and a dust removal section 13 which are connected in sequence as one body. The air inlet connection section 11 is connected to the axial flow fan. The sprayer 4 is installed on the flared pipe section 12. The water collector 5 is installed on the bottom surface of the dust removal section 13. The water collector 5 includes a water trough 51. A flange 52 is fixedly connected to the open end of the water trough 51. A drain pipe 53 is fixedly passed through the center of the water trough 51. A row of first jacks 14 and a row of second jacks 15 that penetrate the dust removal section 13 are symmetrically provided on both sides of the top surface of the dust removal section 13 along the airflow direction. A row of V-shaped sockets 16 are provided in the middle of the top surface of the dust removal section 13, and the V-shaped sockets 16 are arranged alternately with the first sockets 14 and the second sockets 15 of the dust removal section 13. The first dust water collector 2 is installed on the first socket 14 through the top surface of the dust removal section 13. The second dust water collector 3 is installed on the second socket 15 through the top surface of the dust removal section 13. The first dust water collector 2 and the second dust water collector 3 are installed on the V-shaped socket 16 through the top surface of the dust removal section 13.

Wherein, the sprayer 4 includes an annular tube 41 arranged on the outside of the expanded pipe section 12. A plurality of branch pipes 42 pointing to the center line of the annular tube 41 are fixed on the annular tube 41, and the branch pipes 42 are fixed on the expanded pipe section 12. A spray head 43 is installed at the end of the branch pipe 42. A water inlet pipe 44 is fixedly connected to the annular tube 41. The sprayer 4 evenly sprays in an annular spray circle in the expanded pipe section 12 to form a mist curtain. Wherein, the angle between the first socket 14 and the side wall of the dust removal section 13 is 45°. The angle between the second socket 15 and the side wall of the dust removal section 13 is 45°. The angle between the V-shaped socket 16 is 90°. The first dust water collector 2 includes a rectangular vertical plate 21. A drain plate 22 with a right-angled trapezoidal structure is fixed on one side of the lower end of the rectangular vertical plate 21. A plug 23 of a right-angled trapezoidal structure is fixed on the same side of the upper end of the rectangular vertical plate 21, and a rubber ring 24 that is sealed and matched with the inner wall of the first plug hole 14 is embedded and installed on the peripheral side of the plug 23. An ear plate 25 with a threaded hole is fixed on the plug 23, and the first dust water collector 2 can be fixed on the top of the dust removal section 13 by passing a bolt through the ear plate 25. A stainless steel gas-liquid filter 26 is installed between the side of the rectangular vertical plate 21 and the drain plate 22 and the plug 23. The structural features of the second dust water collector 3 are symmetrically arranged with the structural features of the first dust water collector 2. During installation, the first dust water collector 2 and the second dust water collector 3 both correspond to the airflow with one side of the gas-liquid filter 26. The water mist containing dust is filtered when passing through the gas-liquid filter 26, and flows downward along the gas-liquid filter 26 by its own gravity under the gathering of dust-containing water, and finally enters the water collector 5 below through the drain plate 22 at the lower end of the dust water collector for gathering and collecting debris.

The axial flow fan draws the dust on the working surface into the dust collector bellows 1, and the dust is mixed with the mist curtain generated by the sprayer 4. The slightly larger dust settles after being humidified and weighted by the sprayer 4, and the dust that has not settled is moistened by the spray. The first dust water collector 2 and the second dust water collector 3 capture the remaining dust particles. The stainless steel gas-liquid filter 26 of the first dust water collector 2 and the second dust water collector 3 captures the dust-containing water mist. The first dust water collector 2 and the second dust water collector 3 are distributed in a zigzag shape in the dust collector box, forcing the dust-containing airflow to pass through multiple zigzag routes. The wet dust and sewage converge along the first dust water collector 2 and the second dust water collector 3 and flow into the water collector 5 for discharge, thereby achieving the purpose of dust reduction.

The inner bottom surface of the dust removal section 13 is located at the periphery of the first plug hole 14 and is fixed with a first confining groove 17. The inner bottom surface of the dust removal section 13 is located at the periphery of the second plug hole 15 and is fixed with a second confining groove 18. The inner bottom surface of the dust removal section 13 is located at the periphery of the V-shaped plug hole 16 and is fixed with a V-shaped confining groove 19. The first confining groove 17 and the second confining groove 18 are provided to ensure that the dust-containing water mist captured by the first dust water collector 2 and the second dust water collector 3 flows smoothly downward to the water collector 5 for discharge, and to prevent the converged water flow from being carried away backward by the air flow.
