Therefore, the adsorption and desorption rates of the CO2 humidifying adsorption film on CO2 are improved.

Description

Technical Field

[0001] The utility model relates to the technical field of CO2 direct air capture, and particularly relates to an assembly device for a carbon dioxide variable humidity adsorption membrane. Background Art

[0002] With the rapid development of the global industrial field, the combustion amount of fossil fuels has increased year by year, resulting in a rapid rise in the concentration of CO2 in the atmosphere, causing a more and more serious greenhouse effect, and bringing severe challenges to the living environment of human beings. The CO2 direct air capture technology uses adsorbents to physically or chemically react to directly capture CO2 from the air, and can deal with CO2 generated by mobile and small emission sources such as cars and airplanes. Due to its flexible and convenient characteristics and the ability to deal with mobile CO2 emission problems, the direct air capture technology is considered to be one of the most potential CO2 negative emission capture technologies.

[0003] In recent years, CO2 variable humidity adsorbents have been widely studied as a new type of low-energy-consuming capture material. CO2 variable humidity adsorbents will show different affinities for CO2 with the change of environmental humidity. Specifically, in a dry environment, the adsorbent can automatically adsorb CO2 in the ambient air; when the adsorbent is wetted, it will spontaneously release the adsorbed carbon dioxide to realize the regeneration of the adsorbent.

[0004] At present, the CO2 variable humidity adsorbents studied more in the field are mainly in powder form, such as ion exchange resins, activated carbon, quaternized biomass materials, etc. If the powder materials are directly used as adsorption materials, they are extremely easy to lose and agglomerate after absorbing water. Mixing the powder materials with substrate materials such as polypropylene to form a heterogeneous membrane can solve this problem. However, when the membrane materials are filled in the CO2 capture tower, they are easy to fit together, affecting the humidification or drying process of the membrane materials. How to reasonably fill the CO2 variable humidity adsorption membrane in the limited space of the CO2 capture tower, while ensuring good gas fluidity to promote drying, humidification, and the corresponding adsorption and desorption processes, is a technical problem urgently to be solved in this field. Summary of the Invention

[0005] In order to overcome the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide an assembly device for a carbon dioxide variable humidity adsorption membrane. The utility model utilizes the structural characteristics of the corrugated mesh to form uniform intervals and voids in the wound adsorption membrane and the corrugated mesh, avoiding the self-fitting of the CO2 variable humidity adsorption membrane, thereby ensuring the diffusion and transmission of gas and moisture, and effectively improving the drying and humidification efficiency of the CO2 variable humidity adsorption membrane, thereby improving the adsorption and desorption rates of the CO2 variable humidity adsorption membrane for CO2.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An assembly device for a carbon dioxide variable humidity adsorption membrane, comprising a metal mesh cover 1, a corrugated mesh 2, a CO2 variable humidity adsorption membrane 3, a cable tie 4, and a metal mesh frame 5; the CO2 variable humidity adsorption membrane 3 and the corrugated mesh 2 are laminated and then wound together, and the cable tie 4 bundles the wound CO2 variable humidity adsorption membrane 3 and the corrugated mesh 2 to form an adsorption membrane assembly, and there are uniform intervals and voids in the adsorption membrane assembly; the metal mesh frame 5 is used to fix the bundled adsorption membrane assembly in the frame, and a metal mesh cover 1 and the metal mesh frame 5 are combined into an integral structure.

[0008] The CO2 variable humidity adsorption membrane 3 is a variable humidity adsorption material that regulates CO2 adsorption and desorption based on humidity. It can automatically adsorb CO2 in a dry environment and automatically desorb CO2 in a humid environment after adsorption saturation.

[0009] The packing density of the CO2 variable humidity adsorption membrane is regulated by adjusting the wave amplitude of the corrugated mesh.

[0010] The corrugated mesh 2 is a mesh material with a periodic corrugated structure, and is made of metal or plastic.

[0011] The periodic corrugated structure includes triangular corrugations, sinusoidal corrugations, square corrugations or trapezoidal corrugations.

[0012] The main body of the CO2 variable humidity adsorption membrane 3 is rectangular sheet-shaped, and its length and width are the same as those of the corrugated mesh 2, so as to facilitate lamination and winding with the corrugated mesh 2.

[0013] The cable tie 4 is made of plastic or metal.

[0014] The metal mesh frame 5 is a net-shaped cylinder with a bottom surface, and its bottom surface is a net-shaped disc. The metal mesh cover 1 is also a net-shaped disc. The metal mesh frame 5 and the metal mesh cover 1 together fix the adsorption membrane assembly in the frame to form an adsorption membrane unit, and multiple adsorption membrane units can be stacked upwards.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By utilizing the structural characteristics of the corrugated mesh, the present utility model forms uniform intervals and voids in the wound CO2 variable humidity adsorption membrane and the corrugated mesh, avoiding the self-adhesion of the CO2 variable humidity adsorption membrane, thereby ensuring the diffusion and transmission of gas and moisture, effectively improving the drying and humidifying efficiency of the CO2 variable humidity adsorption membrane, and thus increasing the adsorption and desorption rates of the CO2 variable humidity adsorption membrane for CO2.

[0017] 2. The packing density of the CO2 variable humidity adsorption membrane in the CO2 capture tower (i.e., the mass of the CO2 variable humidity adsorption membrane per unit space) can be regulated by adjusting the wave amplitude of the corrugated mesh. When more materials need to be packed in the CO2 capture tower, reducing the wave amplitude of the corrugated mesh can achieve this, and this will not cause the self-adhesion of the CO2 variable humidity adsorption membrane itself, but only reduces the interval between the membranes.
