[0065] The use method and advantages of the present application are as follows:

[0066] As Figure 1 , Figure 2 ,Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 as shown in FIG. 6:

[0067] S1: when the adsorption starts, the driving motor 601 starts to operate, driving the rotating shaft 602 to rotate, while the rotating shaft 602 rotates, the bottom cone-shaped driving wheel set 603 rotates, in turn, driving the rotating shaft 604 to rotate, the trigger block 605 at the top of the rotating shaft 604 also starts to move in a circular motion, the second gear 607 at the top of the rotating shaft 602 meshes with the second gear ring 802 in the temperature control mechanism 8, providing power for the temperature control mechanism 8, the control box 501 starts the pump body, delivering liquid through the main pipe 502 to the spray pipe 503 above the first adsorption bed 402 and the third adsorption bed 404, spraying the first adsorption bed 402 and the third adsorption bed 404, at the same time, the spray wastewater enters the water storage tank 201 through the through hole 302 and the filter plate 202, the water pump 504 in the water storage tank 201 delivers water through the water delivery pipe 505 to the rotary spray arm 506, which rotates under the drive of the third gear 807, spraying and cooling the area between the second adsorption bed 403 and the third adsorption bed 404, the liquid produced by spraying is guided by the water guide table 301 at the bottom of the inner tower 3, flows into the water storage tank 201 at the bottom of the outer tower 2 through the through hole 302, and the filter plate 202 at the inlet of the water storage tank 201 filters the liquid to prevent impurities from blocking the pipeline for subsequent recycling, the gas treated by the first adsorption bed 402, the second adsorption bed 403 and the third adsorption bed 404 is discharged through the exhaust pipe 405 at the top of the inner tower 3, the fan 406 delivers the gas to the filter box 407, which further filters the gas to ensure that the discharged gas meets the emission standard;

[0068] S2: The waste gas containing carbon dioxide enters the inner tower 3 through the inlet pipe 401, and most of the waste gas enters the air pipe 701 because the position of the air pipe 701 is higher than that of the inlet pipe 401. In the air pipe 701, the driving mechanism 6 drives the gas gathering impeller 702 to rotate through the conical driving wheel set 603, the gas gathering impeller 702 gathers the waste gas, and the waste gas flows upward into the air pipe 701, and at the same time, in the rotating process of the rotating shaft 604, the trigger block 605 intermittently abuts against the push bar 709 on the sidewall of the rotating frame 708. When the trigger block 605 pushes the push bar 709, the rotating frame 708 overcomes the elastic force of the spring 707 and rotates on the circular ring 706 by a small amplitude, the rotating frame 708 drives the synchronous frame 713 and the first lifting arc strip 714 to rotate, the first lifting arc strip 714 pushes the first mounting block 716 on the side of the cover 715, so that the cover 715 slides downward in the shunt 705, and the cover 715 blocks the top hole 712. At this time, the rotating frame 708 opens the side hole 710, so that the waste gas in the shunt 705 flows from the side hole 710. When the trigger block 605 is separated from the push bar 709, the spring 707 is reset, the rotating frame 708 is reset, the first lifting arc strip 714 pushes the first mounting block 716 on the side of the cover 715, so that the cover 715 slides upward in the shunt 705, the top hole 712 is opened, and the side hole 710 is closed at the same time, the waste gas flows from the top hole 712, and the waste gas is alternately shunted and further uniformly dispersed;

[0069] S3: After the waste gas is fully contacted with the first adsorption bed 402, it continues to flow upward and is contacted with the second adsorption bed 403, and further carbon dioxide adsorption is performed. In the adsorption process, heat is released, which causes the adsorption capacity of the adsorption bed to decrease. When the temperature between the second adsorption bed 403 and the third adsorption bed 404 increases, the second gear 607 at the top of the rotating shaft 602 drives the outer ring body 801 in the temperature control mechanism 8 to rotate, the second lifting arc strip 805 on the inner wall of the outer ring body 801 is in contact with the second mounting block 804 on the outer surface of the third adsorption bed 404, and as the outer ring body 801 rotates, the second lifting arc strip 805 pushes the second mounting block 804, so that the third adsorption bed 404 slides upward in the gap 803 of the inner tower 3, the third adsorption bed 404 is lifted, the distance between the third adsorption bed 404 and the second adsorption bed 403 is increased, air circulation is promoted, and cooling treatment is performed.
