At the same time, various agents can be mixed in the mixing bin 1206 according to requirements, avoiding direct contact with the agents, reducing the safety risks of operators, avoiding the harm of harmful agents to the human body, and accurately controlling the dosage of the agents. Embodiment 2

[0026] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described below:

[0027] As a preferred implementation manner, an air outlet 15 is provided on the upper end surface of the spray tower body 1, an air inlet 16 is provided on the left side at the lower end of the spray tower body 1, and a drain valve 17 is provided below the air inlet 16; further, the air outlet 15 is used to discharge the gas treated by the spray tower to meet the environmental protection standards. The external gas is introduced into the spray tower body 1 through the air inlet 16 for treatment, and the drain valve 17 effectively discharges the wastewater or sewage generated in the tower to ensure the cleanliness of the operation in the tower.

[0028] As a preferred implementation manner, an observation window 18 is provided on the left side of the outer surface of the spray tower body 1, a maintenance port 19 is provided on the left side of the air outlet 15, and a demister 11 is provided below the air outlet 15; further, the observation window 18 enables the operator to conveniently check the operation status inside the spray tower body 1 and promptly discover abnormal situations. When the spray tower needs to be maintained or cleaned, access can be made through the maintenance port 19 for quick necessary maintenance and cleaning. The demister 11 removes the fine droplets in the gas to ensure the smoothness of the air outlet 15 and improve the purity of the gas.

[0029] As a preferred implementation manner, a water suction pipe 4 is provided at the center of the inner cavity of the circulation water tank 3, a heating pipe 7 is provided on the left side of the water suction pipe 4, a vertical water pump 5 is provided on the upper end surface of the circulation water tank 3, and a water supply pipe 6 is provided on the left side of the vertical water pump 5; further, the water suction pipe 4 extracts the water in the circulation water tank 3, enters the water supply pipe 6 through the vertical water pump 5, and then is connected to the spray mechanism 8 for water supply.

[0030] As a preferred implementation manner, a medicine supply pipe 13 is provided on the left side of the mixing bin 1206, a dosing pump 14 is provided at the center of the medicine supply pipe 13, and one end of the medicine supply pipe 13 far from the mixing bin 1206 is connected to the water supply pipe 6; further, the medicine supply pipe 13 is used to transport the agent, and the dosing pump 14 extracts the agent and sends it into the water supply pipe 6 through the medicine supply pipe 13.

[0031] As a preferred embodiment, the filler in the inner cavity of the filler layer 10 is polypropylene plastic multi-faceted hollow balls 101. A spiral nozzle 9 is arranged below the spraying mechanism 8, and several groups of spiral nozzles 9 are provided. Further, the polypropylene plastic multi-faceted hollow balls 101 have a high gas velocity, many blades, small resistance, and a large specific surface area, which can fully solve gas-liquid exchange, have small resistance, large operating flexibility, light weight, high strength, can withstand high temperatures above 120 degrees, have corrosion resistance to a variety of organic solvents, acids and alkalis, and have a service life of greater than or equal to 5 years. The spiral nozzle 9 sprays the liquid of the spraying mechanism 8, and the spiral structure is not easily blocked, making maintenance and management convenient.

[0032] The working process of the present utility model is as follows: First, when the spray tower body 1 works, the outside gas is introduced into the spray tower body 1 through the air inlet 16 and enters the filler layer 10 for treatment. The water in the circulation water tank 3 is heated by the heating wire on the surface of the heating pipe 7. The water in the circulation water tank 3 is pumped through the water extraction pipe 4 connected by the vertical water pump 5, and the water is transported to the spraying mechanism 8 through the water supply pipe 6. The spraying mechanism 8 is equipped with a spiral nozzle 9 inside, which can atomize the water and uniformly distribute it on the surface of the filler layer 10. When the gas passes through the filler layer 10, it makes full contact with the water sprayed down. Due to the high gas velocity, many blades and small resistance of the polypropylene plastic multi-faceted hollow balls 101, and the large specific surface area, gas-liquid exchange can be fully solved. After the water is sprayed, it will flow back to the pool 2 and then be pumped back to the circulation water tank 3 to form a circulation system, saving water. Through the medicine inlet 1203, the operator can conveniently put medicine into the medicine adding bucket 1201. The three groups of medicine storage pools 1202 can store different types of medicine at the same time to meet various treatment requirements. The valve 1205 is used to control the opening and closing of the medicine discharge port 1204. By controlling the multi-way switch, different medicine storage pools 1202 can be selected to mix the medicine in the medicine mixing bin 1206, and then the medicine is pumped out by the medicine adding pump 14, flows into the medicine delivery pipe 13 and is sent into the water supply pipe 6 to be mixed with the liquid of the circulation water tank 3 connected to the spraying mechanism 8. The demister 11 uses the physical separation principle to intercept the liquid droplets in the gas, and the clean gas is discharged through the air outlet 15. The operator observes the gas-liquid distribution and the state of the filler in the tower through the observation window 18. When a certain amount of wastewater accumulates in the spray tower body 1, the excess liquid can be quickly discharged through the drain valve 17. When maintenance or cleaning of the spray tower is required, access can be made through the inspection port 19. The above is the working principle of this gas-liquid spray tower.

[0033] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
