[0023] Reference Figure 1-4 The utility model embodiment is a device for carbon dioxide adsorption and filtration, which includes: a bottom plate 4, the upper surface of the bottom plate 4 is fixedly connected with a primary treatment box 1, which is used for preliminary adsorption and filtration of carbon dioxide gas, the left surface of the primary treatment box 1 is fixedly connected with a feed pipe 13, which is used for the carbon dioxide gas to be treated to enter the primary treatment box 1, the feed pipe 13 is connected with the primary treatment box 1, the inner wall of the primary treatment box 1 is slidably connected with a filter placement bin 14, which is used to place an adsorbent, and the inner wall of the primary treatment box 1 is provided with a limiting groove, which is used to limit the filter placement. The filter placement bin 14 is moved, and the filter placement bin 14 is located inside the limiting groove. The front surface of the filter placement bin 14 is fixedly connected with a sealing plate 2, which is used to ensure the sealing of the primary treatment box 1 after the filter placement bin 14 is taken out. The front surface of the sealing plate 2 is fixedly connected with a handle, which is used to facilitate the pulling of the filter placement bin 14. The lower bottom wall of the filter placement bin 14 is provided with filter holes. The left surface of the primary treatment box 1 is fixedly connected with a fan B11 for moving power of the gas. The left surface of the fan B11 is fixedly connected with a discharge pipe 12 for the channel of the discharged gas.

[0024] A fan A3 is fixedly connected to the right surface of the primary treatment box 1 for providing power for conveying gas. Both the fan B11 and the fan A3 are connected to the primary treatment box 1. A delivery pipe 9 is fixedly connected to the right surface of the fan A3 for conveying the gas channel. The end of the delivery pipe 9 away from the fan B11 is fixedly connected to the secondary treatment tank 6 for further filtering and adsorbing the carbon dioxide gas. The delivery pipe 9 is connected to the secondary treatment tank 6. An output pipe 7 is fixedly connected to the right surface of the secondary treatment tank 6 for discharging the treated gas. The output pipe 7 is connected to the secondary treatment tank 6. A valve 8 is provided on the side surface of the output pipe 7 for controlling the flow rate of gas discharge. A sealing cover 10 is rotatably connected to the upper surface of the secondary treatment tank 6 through a hinge for convenient opening of the secondary treatment tank 6. A pull ring is fixedly connected to the upper surface of the sealing cover 10 for convenient opening and closing of the secondary treatment tank 6. A support 5 is fixedly connected to the upper surface of the bottom plate 4 for supporting the secondary treatment tank 6. The upper end of the support 5 is fixedly connected to the lower surface of the secondary treatment tank 6.

[0025] Working principle: The gas containing carbon dioxide enters the primary treatment box 1 through the feed pipe 13. In the primary treatment box 1, the gas contacts the adsorbent (such as activated carbon) in the filter placement bin 14. Through physical adsorption, some carbon dioxide molecules are captured on the surface of the adsorbent. The filter placement bin 14 allows the adsorbent to be easily removed and replaced from the primary treatment box 1, so as to facilitate regular maintenance and renewal of the adsorbent. The carbon dioxide content of the gas after preliminary filtration in the primary treatment box 1 has been reduced. At this time, the fan B11 is started to extract part of the gas and discharge it through the discharge pipe 12 for random inspection. The purpose of the random inspection is to check whether the gas after primary treatment meets the preset emission standards. If it meets the standards, it is directly discharged. If the gas does not meet the emission standards, the fan A3 is started. The fan A3 transports the gas that does not meet the emission standards to the secondary treatment tank 6 through the delivery pipe 9. In the secondary treatment tank 6, the gas further contacts the chemical adsorbent in the tank. Through chemical adsorption, the remaining carbon dioxide molecules are more thoroughly removed. This chemical adsorption usually has higher adsorption capacity and selectivity, which can ensure that the gas meets the emission standards when leaving the secondary treatment tank 6. Finally, the gas filtered by the secondary treatment tank 6 is discharged through the output pipe 7. The valve 8 on the output pipe 7 can control the emission speed and flow of the gas. When it is necessary to replace or maintain the adsorbent in the secondary treatment tank 6, it can be operated by opening the sealing cover 10.
