Carbon dioxide recovery system

A carbon dioxide recovery system configured to separate and recover carbon dioxide from a carbon dioxide containing gas, the carbon dioxide recovery system comprising:

• an adsorption unit that includes an adsorbent material which is configured to adsorb and desorb the carbon dioxide, wherein:
• the adsorbent material is configured to radiate heat in response to adsorption of the carbon dioxide and is configured to absorb the heat in response to desorption of the carbon dioxide;
• the adsorption unit is one of a plurality of adsorption units, and adjacent two adsorption units among the plurality of adsorption units contact with each other;
• when one of the adjacent two adsorption units adsorbs the carbon dioxide, another one of the adjacent two adsorption units desorbs the carbon dioxide;
• heat is exchanged between the one of the adjacent two adsorption units, which adsorbs the carbon dioxide, and the another one of the adjacent two adsorption units, which desorbs the carbon dioxide;
• the adjacent two adsorption units are defined as a primary adsorption unit and a secondary adsorption unit, respectively;
• the primary adsorption unit is one of a plurality of primary adsorption units among the plurality of adsorption units;
• the secondary adsorption unit is one of a plurality of secondary adsorption units among the plurality of adsorption units;
• and
• the plurality of primary adsorption units and the plurality of secondary adsorption units are alternately stacked in a predetermined direction.
