[0039] Among them, the water mist carrying dust will fall to the bottom of the inner cavity of the dust suppression hood 1, and then be discharged into the water collecting box 9. After being filtered by the filter component inside the water collecting box 9, the clean water will gather at the bottom of the water collecting box 9.

[0044] Among them, when the nozzle seat 27 moves inside the rectangular groove 28, since one side of the rubber wheel ring 37 is located on the outside of the nozzle seat 27, the rubber wheel ring 37 contacts the inner wall of the rectangular groove 28, and the rubber wheel ring 37 will rotate inside the track groove opened inside the nozzle seat 27 due to the friction between the rubber wheel ring 37 and the side wall of the rectangular groove 28, thereby driving the connecting ring 38 to rotate, prompting the pressure rod 42 to move. The bottom of the pressure rod 42 is arranged in an arc shape, and the pressure rod 42 is against the wave protrusion 39, which can reduce the friction resistance of the pressure rod 42 when the pressure rod 42 contacts and moves with the wave protrusion 39, and the movement is smoother. When the pressure rod 42 rotates, the bottom of the pressure rod 42 contacts the wave protrusion 39, and with the cooperation of the spring 44, the wave protrusion 39 will swing up and down, thereby causing the atomizing nozzle 41 to swing, changing the direction of the spray hole of the atomizing nozzle 41, making the spraying range wider, and improving the dust reduction effect.

[0046] Among them, the water mist carrying dust will fall to the bottom of the inner cavity of the dust suppression hood 1, gather in the water collecting tank 19 opened on the top of the water collecting seat 18, and then be discharged into the interior of the water collecting box 9 through the water leakage hole 20, and then be initially filtered through the filter hole 29 inside the filter partition 34 to filter out large particles in the sewage. After that, the sewage will infiltrate into the interior of the activated carbon layer 33, and after adsorption and filtration by the activated carbon layer 33, fine particles and residual pollutants will be removed, and then it will be finally filtered through the filter hole 29 at the bottom of the filter frame 10, and the final filtered water will fall into the bottom of the inner cavity of the water collecting box 9, which is convenient for subsequent recycling, saving resources, and improving the use effect of the device.

[0047] The specific working principle and use method of the present invention are explained in detail below: First, the device is installed at the outlet end of the exhaust gas exhaust pipe by connecting the installation tube 2.
