[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4This utility model provides a technical solution: a dosing device for waste gas treatment, comprising: a waste gas treatment box 1, a booster pump 2 fixedly connected to the top of the waste gas treatment box 1, an inlet pipe 3 fixedly connected to the left side wall of the booster pump 2, and a connecting pipe 4 fixedly connected to the right side wall of the booster pump 2. The connecting pipe 4 is L-shaped. Waste gas enters the booster pump 2 through the inlet pipe 3, and after being pressurized by the booster pump 2, the flow rate of the waste gas is increased. A dosing tank 5 is fixedly connected to the right side wall of the waste gas treatment box 1, and a dosing pipe 6 is fixedly connected to the top of the dosing tank 5. A valve is fixedly connected to the dosing pipe 6. An observation window 7, made of transparent glass, is fixedly connected to the right wall of the dosing tank 5. A scale 8 is installed on the observation window 7, allowing observation of the amount of medicine inside the dosing tank 5. If the amount is insufficient, medicine can be added through the dosing pipe 6 to ensure adequate dosage. A water pump 9 is fixedly connected to the bottom of the dosing tank 5. A water outlet pipe 10 is fixedly connected to the top output end of the water pump 9. When the water pump 9 is started, the medicine in the dosing tank 5 is discharged through the water outlet pipe 10. The end of the connecting pipe 4 furthest from the booster pump 2 is fixedly connected to the water outlet pipe 10, and the connection between the connecting pipe 4 and the water outlet pipe 10 is angled. Not only does it facilitate the injection of waste gas, but it also atomizes the liquid medicine in the outlet pipe 10 under the action of the waste gas, thereby increasing the contact area between the waste gas and the liquid medicine and improving the treatment efficiency of the waste gas. The end of the outlet pipe 10 away from the water pump 9 is rotatably connected to a mixing pipe 11. The circumferential surface of the mixing pipe 11 is provided with a number of discharge holes 12, which are evenly distributed on the mixing pipe 11. A fixing rod 13 is fixedly connected to the bottom surface of the inner side of the mixing pipe 11. A mixing plate 14 is fixedly connected to the circumferential surface of the fixing rod 13, which is also evenly distributed on the fixing rod. On 13, the mixing pipe 11 is located inside the exhaust gas treatment box 1. The mixing pipe 11 is provided with a mixing chamber. The mixing plate 14 is located inside the mixing chamber. The mixing plate 14 is inclined and located above the discharge hole 12. When high-speed exhaust gas is injected into the water outlet pipe 10, the liquid medicine discharged from the water outlet pipe 10 is atomized and enters the mixing pipe 11 together, and hits the mixing plate 14. Because the mixing plate 14 is inclined, it rotates after being hit, thereby stirring the exhaust gas and the liquid medicine, so that they are fully mixed and reacted, improving the uniformity of exhaust gas treatment. The treated exhaust gas is discharged from the discharge hole 12.

[0025] A right flow valve 15 is fixedly connected to the circumference of the air inlet pipe 3 to facilitate control of the flow rate of the exhaust gas. A left flow valve 16 is fixedly connected to the circumference of the water outlet pipe 10 to facilitate control of the flow rate of the liquid medicine. An exhaust pipe 17 is fixedly connected to the circumference of the exhaust gas treatment box 1. The exhaust pipe 17 is located below the mixing pipe 11 and is used to discharge the treated exhaust gas. A support column 18 is fixedly connected to the bottom of the exhaust gas treatment box 1. There are multiple support columns 18, which are evenly distributed at the bottom of the exhaust gas treatment box 1.

[0026] Working principle: Exhaust gas enters the booster pump 2 through the inlet pipe 3. After being pressurized by the booster pump 2, the flow rate of the exhaust gas is increased. The water pump 9 is started, and the liquid medicine in the dosing tank 5 is discharged through the outlet pipe 10. The connection between the connecting pipe 4 and the outlet pipe 10 is set at an angle to facilitate the injection of exhaust gas. Under the action of high-speed exhaust gas, the liquid medicine in the outlet pipe 10 is atomized, thereby increasing the contact area between the exhaust gas and the liquid medicine. After being atomized, the liquid medicine discharged from the outlet pipe 10 enters the mixing pipe 11 together with the exhaust gas and hits the mixing plate 14. Because the mixing plate 14 is set at an angle, it rotates after being hit, thereby stirring the exhaust gas and the liquid medicine, so that they are fully mixed and reacted, improving the uniformity of exhaust gas treatment. The treated exhaust gas is discharged from the discharge hole 12 and then discharged from the exhaust pipe 17 into the exhaust gas treatment box 1.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
