[0018] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0019] like Figure 1-3 The waste gas treatment device based on carbon neutralization shown includes a housing 1, and a partition 13 is provided in the housing 1 to divide the interior of the housing 1 into a filter area 11 and an absorption area 12, and the filter area 11 and the absorption area 12 are independent of each other. The filter area 11 and the absorption area 12 are respectively equipped with sealed doors and windows (not shown), so as to facilitate disassembly and observation. The filter area 11 and the absorption area 12 are connected by a connecting pipe 15, and the waste gas of the filter area 11 can enter the absorption area 12 through the connecting pipe 15.

[0020] The filter area 11 is provided with a faceplate 2, and the faceplate 2 is provided with a plurality of through holes. The through holes include a first through hole 21 and a second through hole 22 that are connected to each other, the first through hole 21 is a Venturi structure, and the second through hole 22 is a threaded hole. The end of the air filter element 23 is provided with a boss 24, and the boss 24 is screwed into the second through hole 22, which saves a lot of labor costs for welding seams, and the structure is more concise, convenient and easy to disassemble.

[0021] A back-blowing nozzle 25 is provided above the through hole, which can back-blow compressed air through the through hole into the air filter element 23, thereby realizing self-cleaning of the air filter element 23. The first through hole 21 is a Venturi structure, that is, a through hole having the same internal structure as the Venturi tube is directly opened on the faceplate 2, thereby avoiding welding the Venturi tube to the faceplate 2, thereby ensuring the acceleration effect of the Venturi on the airflow, saving a large amount of labor cost for welding, and reducing the material cost.

[0022] The absorption zone 12 is provided with absorption liquid 8, a motor 4, a hollow shaft 5 driven by the motor 4, and a plurality of hollow stirring blades 51 connected to the lower part of the hollow shaft 5. The motor 4 is connected to the housing 1. The absorption liquid 8 is a carbon dioxide absorption liquid. The hollow shaft 5 is sealed and connected to the shaft of the motor 4.

[0023] The connecting pipe 15 is connected to the hollow rotating shaft 5, so that the exhaust gas can enter the hollow rotating shaft 5 through the connecting pipe 15. A plurality of air outlets 50 are provided on the lower part of the hollow rotating shaft 5 and the hollow stirring blade 51, so that the exhaust gas entering the hollow rotating shaft 5 can escape through the air outlets 50. The lower part of the hollow rotating shaft 5 is located in the absorption liquid 8, so that the exhaust gas directly enters the absorption liquid 8 after coming out of the air outlet 50, so that the carbon dioxide in the exhaust gas is absorbed by the absorption liquid 8. The motor 4 drives the hollow rotating shaft 5 and the hollow stirring blade 51 to rotate, stirring the absorption liquid 8 while releasing the exhaust gas, so that the exhaust gas can fully contact with the absorption liquid 8, thereby improving the absorption efficiency of carbon dioxide in the exhaust gas, thereby improving the reaction efficiency of carbon neutralization.

[0024] The connecting tube 15 is provided with a through hole 150 and an annular wall 151 extending along the edge of the through hole 150 toward the inside of the connecting tube 15 . A first opening 152 is formed between the upper and lower annular walls 151 . The first opening 152 is cylindrical.

[0025] The hollow shaft 5 is clamped with a plurality of O-rings 6. Specifically, a clamping groove is provided on the surface of the hollow shaft 5, and the O-rings 6 are located in the clamping groove. The hollow shaft 5 is provided with a plurality of second openings 53, and a support rod 52 is provided between adjacent second openings 53.

[0026] The hollow shaft 5 passes through the through hole 150 , and the O-ring 6 squeezes the ring wall 151 . The hollow shaft 5 can rotate freely in the through hole 150 when driven by the motor 4 , and the O-ring 6 plays a sealing role to prevent exhaust gas from leaking from the connection between the connecting pipe 15 and the hollow shaft 5 .

[0027] The first opening 152 and the second opening 53 are connected, so that the exhaust gas in the connecting pipe 15 enters the second opening 53 through the first opening 152, and then enters the hollow rotating shaft 5. Since the first opening 152 is cylindrical and the plurality of second openings 53 are arranged in a ring, when the hollow rotating shaft 5 rotates freely in the through hole 150, the exhaust gas in the connecting pipe 15 can always smoothly enter the hollow rotating shaft 5.

[0028] It also includes an air intake pipe 14 connected to the filtration area 11, an exhaust pipe 16 connected to the absorption area 12, and a liquid discharge pipe 17 connected to the absorption area 12. The air intake pipe 14 is provided with a first air pump 31, the connecting pipe 15 is provided with a second air pump 32, and the exhaust pipe 16 is provided with a third air pump 33.

[0029] It also includes a carbon dioxide detector 7 connected to the exhaust pipe 16, which is used to detect whether the carbon dioxide concentration in the treated exhaust gas meets the standard. If it meets the standard, it is directly discharged. If it does not meet the standard, it re-enters the filtering area 11.

[0030] The working principle is as follows: the exhaust gas enters the filter area 11 under the action of the first vacuum pump 31, and is filtered by the air filter element 23 to remove particulate impurities in the exhaust gas. The exhaust gas enters the connecting pipe 15 under the action of the second vacuum pump 32, and enters the hollow shaft 5 from the connecting pipe 15. The hollow shaft 5 rotates under the drive of the motor 4, and the exhaust gas finally emerges through the air outlet 50. The exhaust gas can fully contact with the absorption liquid 8, thereby improving the absorption efficiency of carbon dioxide in the exhaust gas, thereby improving the carbon neutralization reaction efficiency, and the treated exhaust gas is discharged from the exhaust pipe 16.

They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
