An absorption tower 2 is provided above the liquid storage tank 1. An observation pipe is provided at the side end of the absorption tower 2. Two corrugated packings 3 are equidistantly arranged in the absorption tower 2. Packing support plates 4 are provided at the bottom ends of the corrugated packings 3. An air inlet 10 is provided at the side end of the absorption tower 2. Through the arrangement of the corrugated packing 3 and the packing support plate 4, the contact surface area between the gas and the liquid can be better increased, and the mass separation efficiency can be improved; the liquid storage tank 1 is divided into a collection tank 11 and a liquid extraction tank 12. A liquid outlet pipe is provided on the side wall of the collection tank 11, and a butterfly valve is provided on the liquid outlet pipe. A liquid inlet pipe is provided above the liquid extraction tank 12. A second lift pump 8 is provided at the side end of the liquid storage tank 1. A first connecting pipe for communicating with the collection tank 11 is provided at the side end of the second lift pump 8. A second connecting pipe for communicating with the liquid extraction tank 12 is provided on the top surface of the second lift pump 8. Through the separated structure of the collection tank 11 and the liquid extraction tank 12 and the arrangement of the second lift pump 8, the feed liquid can be better diluted in cooperation with the liquid inlet pipe, so as to realize the recycling of the feed liquid; a first lift pump 5 is provided at the side end of the top surface of the liquid storage tank 1 and the absorption tower 2. A transfer pipe 6 is provided at the upper end of the first lift pump 5. A suction pipe for extending into the liquid extraction tank 12 to suck the feed liquid is provided at the lower end of the first lift pump 5. The ends of the transfer pipe 6 are respectively provided with a first sponge drip plate 7 and a second sponge drip plate for adding the feed liquid. Through the arrangement of the first lift pump 5 and the transfer pipe 6, the feed liquid can be better conducted onto the corrugated packing 3.

[0021] In the present utility model, a detection mechanism 9 is provided on the inner bottom surface of the liquid extraction tank 12. The detection mechanism 9 is composed of an alarm box 13 and a floating block 14. A fixed connecting pipe is provided at the lower end of the alarm box 13, and a sliding groove for sliding the floating block 14 is opened on the fixed connecting pipe. Through the setting of the detection mechanism 9, the liquid level in the liquid extraction tank 12 can be detected to avoid affecting the liquid material suction of the first lift pump 5 when the liquid level in the liquid extraction tank 12 is relatively low; the floating block 14 is a round block with magnetism, and the first sponge drip plate 7 and the second sponge drip plate are porous sponge plates. Through the setting of the magnetic floating block 14, the warning of the alarm box 13 can be better closed when the floating block 14 abuts against the alarm box 13. Through the setting of the porous sponge plates, the airflow can be better dispersed to increase the contact area between the airflow and the liquid material, thereby increasing the reaction rate of the liquid material; the corrugated packing 3 is composed of porous corrugated plates 15 and connecting hole plates symmetrically arranged up and down. A plurality of dense attachment holes are opened on the porous corrugated plates 15. Through the setting of the connecting hole plates, the air mass can be re-separated and better contact with the wet attachment holes, thereby improving the reaction efficiency of the absorption tower 2.

[0022] Working principle: When the present utility model is in use, first, the power supply of the lift pump of the device is connected. Then, an initial liquid material is added to the liquid extraction tank 12, so that the liquid material can lift the floating block 14, making the alarm box 13 in a non-alarm state. Subsequently, the gas to be treated is introduced into the air inlet 10. The separated structure of the collection tank 11 and the liquid extraction tank 12 and the setting of the second lift pump 8 can better cooperate with the liquid inlet pipe to dilute the liquid material, thereby realizing the recycling of the liquid material. At the same time, the first lift pump 5 transports the liquid material to the first sponge drip plate 7 and the second sponge drip plate through the transmission pipe 6. Then, the wet first sponge drip plate 7 and the second sponge drip plate drip the liquid material onto the corrugated packing 3. The setting of the porous sponge plates on the corrugated packing 3 can better disperse the airflow to increase the contact area between the airflow and the liquid material, thereby increasing the reaction rate of the liquid material. Subsequently, the gas to be treated passes through the corrugated packing 3 and finally is discharged from the absorption tower 2.
