As shown in fig. 6-8, the application adopts the independent air inlet channel 402 and air outlet channel 403 to divide the gas before and after treatment, so as to avoid the gas before and after treatment from being mixed together and discharged; moreover, the gas needs to directly pass through the adsorption assembly 10, so that the contact area between the gas and the adsorption assembly 10 is larger, and the adsorption effect is better.
Compared to the air carbon capture adsorption device provided in example 1, the gas needs to pass through the adsorption assembly 10 during gas treatment, while resulting in additional resistance, but benefiting from a reasonable shaping design, so that the gas contact area is much larger than that of example 1 under the determined volume condition, namely, the wind speed is reduced and the resistance is reduced.

The application realizes the heating of the heating element and the partial blocking of the air outlet channel 403 and the air inlet channel 402 through the functions of the first conductive baffle 301 and the second conductive baffle 302, so that the gas can realize the switching from the air inlet channel 402 to the air outlet channel 403, and the gas can pass through the adsorption component 10, thereby improving the contact between the gas and the adsorption component 10; the structure design is more compact, and the space design is more reasonable.
The cross-sectional shape of the concave-convex surface may be a wave shape, an arc shape, or the like.
The application designs the adsorption component 10 specifically, so that the adsorption layer 1 is wrapped by the support body 2, the adsorption layer 1 is distributed more uniformly in the inner cavity defined by the support body 2, and the possibility that substances in the adsorption layer 1 are discharged outside along with gas is reduced; the concave-convex surface increases the contact area between the body and the adsorption layer 1, thereby improving the adsorption effect.
Wherein, the supporting body 2 comprises a ventilation filter cloth, and the sealing part of the ventilation filter cloth can be treated by adopting modes of hot melting, viscose, sewing and the like. The heating layer comprises net-shaped heating filaments, has certain mechanical strength and can be combined with the breathable filter cloth into a whole.
