A circulation box 9 is connected, a pH detector 12 is installed on the side of the circulation box 9, a feeding pipe 11 is arranged on the top of the circulation box 9, an acid and alkali resistant pump 10 is connected to the side of the circulation box 9, and the acid and alkali resistant pump 10 is connected to the water inlet pipe 14, the motor 4 is connected to the vertical rod 19, and the vertical rod 19 is provided with two groups of rings 17 on the outer surface, and a stirring piece 18 is installed outside the ring 17, and the water inlet pipe 14 is connected to the ring plate 20, and the ring plate 20 has two groups, and the lower surface of the two groups of ring plates 20 is evenly distributed. The nozzle 21 is installed. When the acid waste gas is actually treated, the acid waste gas passes through the intake pipe 6 The acid waste gas enters the washing box 3. Under the action of the water in the washing box 3, the dust in the acid waste gas contacts the water, and the dust remains in the washing box 3. The water in the washing box 3 cools the acid waste gas, thereby reducing the temperature of the acid waste gas entering the tank body 1. Then the acid waste gas with reduced temperature and dust removal enters the tank body 1. At this time, the acid and alkali resistant pump 10 is turned on. The acid and alkali resistant pump 10 starts to pump the alkaline solution in the circulation box 9 to the water inlet pipe 14. Then the alkaline solution enters the ring plate 20. Then the alkaline solution enters the nozzle 21. Under the action of the nozzle 21, the acid waste gas is The waste gas is sprayed to discharge the acidic gas in the acidic waste gas, and the treated gas is discharged through the exhaust pipe 15. The pH value inside the circulation box 9 is monitored by the pH detector 12, and the alkaline reagent is added in time. When the acidic waste gas enters the water washing box 3, the motor 4 and the cooling component 2 are started synchronously. The motor 4 starts to drive the vertical rod 19 to rotate, and the rotation of the vertical rod 19 drives the ring 17 to rotate. The rotation of the ring 17 drives the stirring piece 18 to rotate. The stirring piece 18 rotates to stir the water inside the water washing box 3, and the cooling component 2 cools the water inside the water washing box 3.

The air cools the water in the cooling pipe 205, and the heat generated by the water is discharged through the air holes 204.

[0029] Working principle: When the acid waste gas is actually treated, the acid waste gas enters the water washing box 3 through the air inlet pipe 6. Under the action of the water body inside the water washing box 3, the dust in the acid waste gas contacts the water body and remains in the water washing box 3. The water body inside the water washing box 3 cools the acid waste gas, thereby reducing the temperature of the acid waste gas entering the tank body 1, thereby avoiding the acid waste gas temperature being too high to affect the normal operation of the equipment, and can reduce the formation of nitrogen oxides by nitrogen and oxygen in the acid waste gas at high temperature, reducing the emission of harmful gases. The acid waste gas after cooling and dust removal enters the tank body 1. At this time, the acid and alkali resistant pump 10 is turned on. The acid and alkali resistant pump 10 starts to pump the alkaline solution in the circulation box 9 to the water inlet pipe 14. Then the alkaline solution enters the ring plate 20. Then the alkaline solution enters the nozzle 21. Under the action of the nozzle 21, the acid waste gas is sprayed to discharge the acid gas in the acid waste gas. The treated gas is discharged through the exhaust pipe 15. The pH value inside the circulation box 9 is monitored by the pH detector 12, and the alkaline reagent is added in time.

[0030] When the acidic waste gas enters the water washing box 3, the motor 4, the axial flow fan 201 and the water pump 206 are started synchronously. The motor 4 starts to drive the vertical rod 19 to rotate, and the rotation of the vertical rod 19 drives the ring 17 to rotate. The rotation of the ring 17 drives the stirring blade 18 to rotate. The stirring blade 18 rotates to stir the water inside the water washing box 3, thereby improving the dust removal and cooling effect on the acidic waste gas. The water pump 206 starts to pump the water flow inside the water washing box 3 to the cooling pipe 205, and then the cooled water returns to the water washing box 3 to complete the cycle. The axial flow fan 201 starts to blow air into the connecting box 202, and then the air enters the wind box 203. The air cools the water in the cooling pipe 205, and the heat generated by the water is discharged through the air hole 204. Through the setting of the cooling component 2, the water inside the water washing box 3 is cooled, which ensures that the water temperature inside the water washing box 3 does not rise, thereby ensuring the cooling effect on the acidic waste gas.
