[0023] like Figure 1-4 As shown, the utility model discloses a through-type shot blasting dust treatment device, including a cyclone tower 1 and a spray component, wherein the spray component is arranged at the upper part of the cyclone tower 1, and a rotatable fan blade 12 is arranged at the upper part of the cyclone tower 1 and below the spray component. During operation, the dust gas is sucked into the cyclone tower 1 by an exhaust fan, and the dust gas can enter the cyclone tower 1 from the lower part or the middle part of the cyclone tower 1. The dust gas moves upward in the cyclone tower 1 through the fan blade 12, and the high-pressure gas drives the fan blade 12 to rotate. After the liquid sprayed by the spray component is fully mixed with the dust gas above the fan blade 12, the dust in the dust gas is melted into the liquid, and the liquid adsorbed with dust moves downward in the cyclone tower 1 under the action of gravity, and the gas after the dust is removed moves upward, and the dust in the dust gas is separated by the liquid. By setting the rotatable fan blade 12, the contact time between the liquid and the gas is increased, and the dust in the dust gas is fully separated.

[0024] Furthermore, the gas coming out of the top of the cyclone tower 1 contains some liquid, and the liquid in the gas needs to be adsorbed before the gas is discharged to protect the environment. An adsorption component is arranged above the spray component, and the adsorption component includes an adsorption box 2. The lower part of the adsorption box 2 is connected to the top of the cyclone tower 1, and a filler demister box 11 is arranged in the adsorption box 2. The gas coming out of the top of the cyclone tower 1 enters the adsorption box 2, and the gas passes through the filler demister box 11 when flowing upward. The filler in the filler demister box 11 adsorbs the liquid and dust in the gas to improve the treatment effect.

[0025] Furthermore, the adsorption box 2 is provided with multiple packing demisting layers in the vertical direction, and each packing demisting layer is provided with multiple packing demisting boxes 11. By providing multiple packing demisting layers, the gas passes through the multiple packing demisting boxes 11 when flowing upward, so as to fully separate the liquid and dust in the gas.

[0026] Furthermore, the packing demister box 11 is opened at both upper and lower ends, and a plurality of porous floating balls are arranged in the packing demister box 11 .

[0027] Furthermore, a spiral sheet in the shape of a DNA double helix structure is arranged inside the cyclone tower 1 and below the spray component to fully utilize the space of the cyclone tower 1, increase the residence time of the gas in the cyclone tower 1, and improve the separation effect.

[0028] Furthermore, the side wall of the cyclone tower 1 is provided with an exhaust gas inlet 4, and the top of the adsorption box 2 is provided with an exhaust gas outlet 3. The exhaust gas inlet 4 is connected to the exhaust fan through an air inlet pipe, and the exhaust fan inhales the dust gas, and the dust gas enters the cyclone tower 1 through the exhaust gas inlet 4 and is discharged from the exhaust gas outlet 3 after separation treatment.

[0029] Furthermore, there are two cyclone towers 1 , which are arranged in parallel; and the exhaust gas inlet 4 is connected to the side walls of the two cyclone towers 1 at the same time.

[0030] Furthermore, the spraying component includes a nozzle, the spraying direction of the nozzle is downward, the nozzle is connected to a connecting water pipe 7, one end of the connecting water pipe 7 away from the nozzle extends out of the cyclone tower 1 and is connected to the water tank 10, and a pump 9 is provided on the connecting water pipe 7. The pump 9 pumps the water in the water tank 10 to the nozzle, and the nozzle sprays water downward, the water contacts the dust gas and dissolves the dust into the water, and the water containing the dust is finally discharged from the bottom of the cyclone tower 1.

[0031] Furthermore, a waste liquid outlet 8 is provided at the bottom of the cyclone tower 1, and the waste liquid outlet 8 is connected to a water collecting tank 5. Water containing dissolved dust is discharged through the waste liquid outlet 8 and collected in the water collecting tank 5.

[0032] Furthermore, the water collecting trough 5, the cyclone tower 1, the adsorption box 2, and the water tank 10 are integrated on the working frame 6. The water collecting trough 5, the cyclone tower 1, the adsorption box 2 are arranged on the working frame 6 from bottom to top, and the water tank 10 is arranged on the side of the working frame 6 to facilitate the movement and transportation of the entire dust treatment device.

[0033] The working principle of a through-type shot blasting dust treatment device is as follows: the dust gas is sucked into the cyclone tower 1 by an exhaust fan, and the dust gas moves upward in the cyclone tower 1 through the fan blades 12. The high-pressure gas drives the fan blades 12 to rotate. After the liquid sprayed by the spray component and the dust gas are fully mixed above the fan blades 12, the dust in the dust gas is melted into the liquid. The liquid adsorbed with dust moves downward in the cyclone tower 1 under the action of gravity, and the gas after the dust is removed moves upward into the adsorption box 2. The gas passes through the packing demister box 11 to remove the liquid and dust in the gas, and is finally discharged from the exhaust gas outlet 3. By setting the rotatable fan blades 12, the contact time between the liquid and the gas is increased, and the dust in the dust gas is fully separated.
