[0027] Specifically, when in use, the exhaust gas enters the cavity of the tower body 10 through the fan and the pipe, and the spraying device in the cavity of the tower body 10 begins to spray the gas entering the cavity of the tower body 10. The sprayed gas is absorbed by the liquid. At this time, the liquid is mixed with harmful gases. By disassembling and connecting the square purification box 19 in the cavity of the tower body 10, the liquid mixed with harmful gases drips into the cavity of the square purification box 19. The cavity of the square purification box 19 is provided with corrugated packing. The corrugated packing (CN202110702443.5) is a prior art and will not be described again. The harmful liquid dripped into the cavity of the square purification box 19 and the square The corrugated filler in the cavity of the purification box 19 reacts. By setting a square purification box 19 and a corrugated filler in the cavity of the square purification box 19, the contact area of ​​the harmful liquid is increased, the full contact and reaction of the harmful gas and the absorption liquid are promoted, the content of harmful substances in the liquid is reduced, and the harm of harmful gases to the environment and human body is effectively reduced. The square purification box 19 is clamped and fixed by setting two clamping plates 18. The operator can pull out and replace the square purification box 19 according to the usage, which is convenient for the operator's operation, improves the working efficiency of the exhaust gas spray absorption tower, and ensures the absorption effect and the normal operation of the equipment.

[0028] like Figure 2 and Figure 4 As shown, the purification clamping assembly also includes a connecting ring 20 and a diverter 21. The connecting ring 20 is fixedly connected to the inner wall of the tower body 10. The diverter 21 located on the bottom of the connecting ring 20 is fixedly connected to the connecting ring 20. A plurality of flow holes 22 are provided on the surface of the diverter 21. The flow holes 22 penetrate the diverter 21, and the diverter 21 is conical.

[0029] Specifically, during use, when the spray device in the cavity of the tower body 10 is opened and working, the amount of liquid sprayed out will be relatively large. By setting a connecting ring 20 and a diverter 21 below the spray port, the sprayed liquid falls into the cavity of the diverter 21. A plurality of flow holes 22 are set on the surface of the diverter 21. The liquid can flow out from the cavity of the diverter 21 through the flow holes 22. The flow holes 22 are evenly distributed on the surface of the diverter 21. The liquid first accumulates on the bottom surface of the diverter 21. When the speed at which the liquid at the bottom is discharged from the cavity of the diverter 21 is lower than the speed at which the liquid drips into the cavity of the diverter 21, the liquid level in the cavity of the diverter 21 rises. When the liquid level rises, the liquid flows out from other flow holes 22. By setting the diverter 21 and the flow holes 22, the dripping speed of the liquid is controlled, thereby controlling the purification of the liquid and improving the purification rate.

[0030] like Figure 1 and Figure 5As shown, the purification clamping assembly also includes a sealing plate 13 and a sealing ring 14. The sealing plate 13 located on the wall of one side of the tower body 10 is detachably connected to the tower body 10, and the sealing ring 14 located on one side of the sealing plate 13 is fixedly connected to the sealing plate 13. The sealing ring 14 is in the shape of a "mouth". The purification clamping assembly also includes multiple groups of screws 12. The surface of the sealing plate 13 is provided with multiple groups of through holes adapted for the screws 12. The screws 12 pass through the through holes and are threadedly connected to the tower body 10.

[0031] Specifically, during use, the operator can rotate the screw 12, and the screw 12 passes through the sealing plate 13 and is threadedly connected to the tower body 10. When the screw 12 is removed, the operator can remove the sealing plate 13 from the surface of the tower body 10, and then the operator can pull out the square purification box 19 in the cavity of the tower body 10. Because both sides of the square purification box 19 are elastically provided with the same clamping plates 18, the clamping plates 18 on both sides clamp and fix the square purification box 19, the operator can pull out the square purification box 19 and replace it, and push the replaced square purification box 19 into the cavity of the tower body 10, and the clamping plates 18 on both sides are clamped by the square purification box. The square purification box 19 is squeezed, and the clamping plates 18 on both sides clamp and fix the square purification box 19. Because one side wall of the sealing plate 13 is fixedly connected to the sealing ring 14, the sealing ring 14 is in close contact with the wall of the square purification box 19. When the operator places the sealing plate 13 on the surface of the tower body 10 and fixes the sealing plate 13 by rotating the screw 12, the sealing ring 14 is in close contact with the wall of the square purification box 19.

[0032] Working principle: exhaust gas enters the cavity of the tower body 10 through the fan and the pipe, and the spray device in the cavity of the tower body 10 starts to spray the gas entering the cavity of the tower body 10. The sprayed gas is absorbed by the liquid. At this time, the liquid is mixed with harmful gases. By disassembling and connecting the square purification box 19 in the cavity of the tower body 10, the liquid mixed with harmful gases drips into the cavity of the square purification box 19. The cavity of the square purification box 19 is provided with corrugated packing. The harmful liquid dripped into the cavity of the square purification box 19 reacts with the corrugated packing in the cavity of the square purification box 19. By setting the square purification box 19, the square purification box A corrugated packing is arranged in the cavity of the chemical box 19 to increase the contact area of ​​the harmful liquid and promote the full contact and reaction between the harmful gas and the absorption liquid. When the spray device in the cavity of the tower body 10 is opened and working, the amount of liquid sprayed out will be relatively large. By arranging a connecting ring 20 and a diverter 21 connected below the spray port, the sprayed liquid falls into the cavity of the diverter 21. The surface of the diverter 21 is provided with multiple groups of flow holes 22. The liquid can flow out of the cavity of the diverter 21 through the flow holes 22. The flow holes 22 are evenly distributed on the surface of the diverter 21. The liquid first accumulates on the bottom surface of the diverter 21. When the bottom When the speed of the liquid discharged from the diverter bucket 21 cavity is lower than the speed of the liquid dripping into the diverter bucket 21 cavity, the liquid level in the diverter bucket 21 cavity rises. When the liquid level rises, the liquid flows out from other flow holes 22. The operator can rotate the screw 12, and the screw 12 passes through the sealing plate 13 and is threadedly connected to the tower body 10. When the screw 12 is removed, the operator can remove the sealing plate 13 from the surface of the tower body 10, and then the operator can pull out the square purification box 19 in the cavity of the tower body 10. Because both sides of the square purification box 19 are elastically connected to the same clamping plates 18, the clamping plates 18 on both sides will hold the square purification box 19. The square purification box 19 is clamped and fixed, and the operator can pull out the square purification box 19 and replace it, and push the replaced square purification box 19 into the cavity of the tower body 10. The clamping plates 18 on both sides are squeezed by the square purification box 19, and at the same time, the clamping plates 18 on both sides clamp and fix the square purification box 19. Because the sealing ring 14 is fixedly connected to the wall of the square purification box 19 on one side of the sealing plate 13, the sealing ring 14 is tightly attached to the wall of the square purification box 19. When the operator places the sealing plate 13 on the surface of the tower body 10 and fixes the sealing plate 13 by rotating the screw 12, the sealing ring 14 is in contact with the wall of the square purification box 19.
