[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1-3 As shown, an exhaust gas scrubbing tower purification treatment device includes a scrubbing tower 1. A drain pipe 3 is fixedly connected and communicated at the bottom side of the scrubbing tower 1. One end of the drain pipe 3 is provided with a solenoid valve 4 installed thereon. The top side of the scrubbing tower 1 is threadedly connected with a threaded top cover 19. A spray ring 20 is fixedly embedded at the bottom side of the threaded top cover 19. The spray ring 20 is fixedly connected with a water delivery pipe 21 through the threaded top cover 19. The middle part of the bottom side of the threaded top cover 19 is fixedly connected with a demisting layer 22. An air outlet pipe 23 is fixedly connected through the threaded top cover 19 at the top side of the demisting layer 22. An observation window 24 is fixedly embedded on one side of the scrubbing tower 1. The solenoid valve 4 is used to control the opening and closing of the drain pipe 3. By pouring water into the water delivery pipe 21, the spray ring 20 can be started, so that the spray ring 20 starts to spray water, thereby increasing the water content of the water storage plate 18. When the gas carrying fine solid particles passes through the water storage plate 18, the outer surfaces of these fine solid particles will be further covered with moisture, thereby increasing their weight and being unable to penetrate the water storage plate 18, and dripping onto the second spray plate 15. The demisting layer 22 can reduce the water content of the exhaust gas after washing. The observation window 24 is used to observe the internal situation of the device, so as to discover and handle problems in time.

The middle part of the inner wall of the bottom side of the scrubbing tower 1 is fixedly connected with a protection pipe 5. An air inlet pipe 6 is fixedly connected to the inner wall of the protection pipe 5. The bottom end of the air inlet pipe 6 extends a certain distance outward through the scrubbing tower 1. The protection pipe 5 is used to protect the air inlet pipe 6. At the same time, the water depth can be engraved on the surface of the protection pipe 5, so as to remind the staff to judge whether the washing liquid 7 is sufficient by observing the water depth of the washing liquid 7 through the observation window 24.
[0018] As a technical optimization scheme of the present utility model, an external box 8 is fixedly connected and communicated on one side of the scrubbing tower 1. A washing liquid 7 is arranged inside the scrubbing tower 1 and the external box 8. The top side of the external box 8 is threadedly connected with a sealing cover 9. A circulating water pump 10 is fixedly connected to the inner wall of the bottom side of the external box 8. The sealing cover 9 is used to pour new washing liquid 7.

The top end of the connecting pipe 11 is flange-connected to a filter cylinder 12. The top end of the filter cylinder 12 is flange-connected to a shunt pipe 13. The filter cylinder 12 is used to filter solid particles in the washing liquid 7, avoid blockage at the first spray plate 14 and the second spray plate 15, and at the same time reduce the solid particles contained in the washing liquid 7 inside the washing tower 1 and the external box 8, avoiding particle precipitation.
[0020] As a technical optimization solution of the utility model, one end of the shunt pipe 13 penetrates through the washing tower 1 and is fixedly connected to a first spray plate 14. One end of the shunt pipe 13 penetrates through the washing tower 1 and is fixedly connected to a second spray plate 15. Both the first spray plate 14 and the second spray plate 15 are horizontally and fixedly connected to the inner wall of the washing tower 1. The first spray plate 14 and the second spray plate 15 can spray atomized washing liquid 7, thereby improving the full reaction with some gases in the waste gas.

The first packing layer 16 and the second packing layer 17 are used to filter solid particles in the waste gas.
[0022] As a technical optimization solution of the utility model, when the utility model is in use, first close the solenoid valve 4, rotate and open the sealing cover 9 and pour sufficient washing liquid 7 into the inside of the washing tower 1 and the external box 8, and then rotate and seal the sealing cover 9 again. At this time, start the circulating water pump 10 to make the water circulation and spraying system of the device operate. Then, send the waste gas into the inside of the device through the intake pipe 6. After the waste gas washing is completed, close the circulating water pump 10 and open the solenoid valve 4 to make the waste washing liquid 7 drain out of the device through the drain pipe 3, thereby completing the washing work of the waste gas.
