[0018] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0019] like Figure 1-Figure 2 As shown, this embodiment provides a tail gas recovery and treatment device, including a three-stage cylinder.

[0020] The three-stage cylinder has a dust removal chamber 1, an adsorption chamber 2 and a liquid treatment chamber 3 from right to left.

[0021] The output end of the dust removal chamber 1 is connected to a cloth bag 12, the area of ​​the cloth bag 12 is larger than the vertical cross-sectional projection area of ​​the dust removal chamber 1, the cloth bag 12 is in a circular mesh shape, an air intake pipe 13 is arranged at the upper end of the dust removal chamber 1, and the dust removal chamber 1 is also formed with an activated carbon plate 11, the activated carbon plate 11 has a plurality of irregularly arranged through holes, the activated carbon plate 11 is located on the side of the cloth bag 12 close to the dust removal chamber 1, and the arrangement of the activated carbon plate 11 can deodorize the exhaust gas once.

[0022] An activated carbon cartridge 21 is disposed in the adsorption chamber 2. The activated carbon cartridge is formed with a plurality of air passages, and the plurality of air passages are interconnected. Specifically, the activated carbon cartridge 21 is in the shape of honeycomb coal, and the activated carbon cartridge 21 performs secondary deodorization.

[0023] The adsorption chamber 2 and the liquid treatment chamber 3 are formed with a baffle plate 35, the height of the baffle plate 35 is one-half or two-thirds of the height of the three-stage cylinder, and the outlet of the air passage of the adsorption chamber 2 is located above the baffle plate 35. Specifically, there is a gap between the activated carbon cylinder 21 and the baffle plate 35.

[0024] An exhaust gas tester is arranged in the liquid treatment chamber 3 to test whether the exhaust gas meets the emission standards. The side wall of the liquid treatment chamber 3 is formed with three nozzles 31 arranged at an interval up and down, and the nozzles 31 are fine water mist nozzles 31. A liquid outlet 37 is formed at the bottom of the liquid treatment chamber 3, and the liquid treatment chamber 3 is also provided with an air outlet. The liquid treatment chamber 3 has a circulating return air component, and the circulating return air component includes a circulating air duct 32 and an exhaust fan 36. One end of the circulating air duct 32 has an opening located on the side wall of the liquid treatment chamber 3, and the other end of the circulating air duct 32 has an opening located at the upper end of the liquid treatment chamber 3. The exhaust fan 36 is located between the circulating air duct 32, and the air inlet end and the air blowing end of the exhaust fan 36 are located in the circulating air duct 32. Specifically, the opening of the circulating air duct 32 on the side wall of the liquid treatment chamber 3 and the air outlet of the liquid treatment chamber 3 are the same, and an air outlet pipeline 33 is also formed in the middle section of the circulating air duct 32, and an electromagnetic valve 34 is provided between the air outlet pipeline 33 and the circulating air duct 32.

[0025] Working principle: the tail gas enters the dust removal chamber 1, passes through the activated carbon plate 11 for a deodorization, and then passes through the bag 12 to enter the adsorption chamber 2. When the tail gas enters the adsorption chamber 2 from the dust removal chamber 1, the bag 12 can hold a large number of dust particles to prevent too many dust particles from blocking the activated carbon cylinder 21 in the adsorption chamber 2. Then the tail gas enters the air passage of the activated carbon cylinder 21 for a second deodorization, and finally enters the liquid treatment chamber 3, where water is sprayed out through the fine water mist nozzle 31. The mist causes a chemical reaction between the exhaust gas and the water mist. When the exhaust gas just enters the liquid treatment chamber 3, the solenoid valve 34 between the circulating air duct 32 and the outlet pipe 33 is closed. Under the action of the exhaust fan 36, the exhaust gas circulates in the liquid treatment chamber 3, and repeatedly reacts through the fine water mist nozzle 31 area until the indicator of the exhaust gas tester reaches the emission mark. The solenoid valve 34 between the circulating air duct 32 and the outlet pipe 33 is closed, the exhaust fan 36 is turned off, and the purified exhaust gas is discharged from the outlet pipe 33.
