[0025] A feed pipe 101 and an exhaust pipe 103 are provided on the top of the reactor shell 1, and a discharge pipe 102 and an air inlet pipe 104 are provided on the bottom of the reactor shell 1. The feed pipe 101 and the discharge pipe 102 as well as the exhaust pipe 103 and the air inlet pipe 104 are arranged diagonally. When in use, the gas and material convection is achieved through the design of diagonal and upper and lower gas-material reverse transportation, thereby improving the carbon capture effect.

[0026] Two notches are provided on the inner wall of the reactor shell 1 corresponding to the positions of the two gear rings 201, and the gear rings 201 are meshed and connected with the gear 107 through the notches. When in use, the notches are designed to mesh the gear rings 201 and the gear 107 to drive the heat preservation tube 2 to rotate.

[0027] A spiral fluidizing plate 301 is fixedly welded on the supporting shaft tube 3 and is provided with a plurality of drainage holes. When in use, the design of the spiral fluidizing plate 301 increases the contact time of carbon capture.

[0028] A plurality of nozzles 302 are fixedly mounted on the support shaft tube 3. When in use, the purified liquid in the support shaft tube 3 is sprayed through the nozzles 302 to evenly catalyze the material and the flue gas (the plurality of nozzles 302 are distributed between the plate gaps of the spiral fluidizing plate 301).

[0029] The filter assembly 4 includes a filter cartridge 401 and a cartridge cover 402. One end of the cartridge cover 402 is threadedly mounted on the filter cartridge 401 and the other end is threadedly mounted on the drain pipe.

At this time, the drive motor 105 can be controlled to drive the transmission shaft 106 to rotate, and the transmission shaft 106 drives the gear 107 to rotate. The gear 107 rotates and drives the insulation barrel 2 to rotate through the meshing action with the gear ring 201. The insulation barrel 2 rotates and contacts with the scraper 108 to scrape off the waste debris attached to the inner wall of the insulation barrel 2. Finally, the exhaust gas catalytic material is connected and discharged through the discharge pipe 102.
