Air carbon capture adsorption device and low-resistance carbon capture system

An air carbon capture adsorption device, comprising:

• a support body;
• a heat exchange assembly, provided in the support body;
• airflow dividing assemblies, provided on two sides of the support body, communicated with the heat exchange assembly and used to divide an airflow in an internal space of the support body while performing heat exchange in the internal space of the support body to form at least two small airflows;
• an adsorption group, dispersedly filled in a space formed by the airflow dividing assemblies and the support body and used to capture carbon by using the small airflow, reduce an operation resistance of the adsorption group or desorb by using heat provided by the heat exchange assembly;
• outer sealing assemblies, provided on two sides of the support body, positioned outside the airflow dividing assemblies and used to limit a movement area of the adsorption group and pre-distribution or redistribution of a gas entering the support body;
• wherein
• the airflow dividing assembly comprises:
• at least two communicating members, staggered between an input end and an output end of the heat exchange assembly and used to enable an airflow to continuously undergo acceleration, deceleration and collision with the communicating members in a micro air duct formed by the communicating members and an extension member, so that the airflow is fully in contact with the adsorption group, and a gap of the adsorption group is kept uniform through pneumatic flow;
• an extension member, provided outside the communicating member, positioned between any two adjacent communicating members as a vortex sheet, and used to divide an airflow flowing through the extension member to form the small airflow while increasing a heat dissipation area of the communicating member;
• the adsorption group is arranged in the extension member and is used for carbon desorption and/or carbon capture;
• the extension member comprises:
• a first portion, provided between the two communicating members;
• a second portion, symmetrically provided with the first portion and used to form a space between the first portion and the second portion while improving a heat exchange area of the communicating member;
• and
• the adsorption group is arranged in the space and used to ensure that a porosity of the adsorption group is controlled during carbon capture;
• and
• the first portion and the second portion are arranged to be V-shaped members and used to enable a cross-section of the airflow in the micro air duct to continuously change, so that the airflow is accelerated and decelerated continuously in the flowing process, a micro negative pressure area is formed, and the adsorption group in the micro air duct is blown up and loosened continuously.
