[Object] Provided is an absorption-type carbon dioxide removal and concentration device that is capable of ensuring a high level of collection efficiency based on carbon dioxide removal or concentration. [Solution] A honeycomb rotor (1) maintaining a carbon dioxide absorbing agent is provided, the honeycomb rotor (1) is divided into a treatment zone (2) and a regeneration zone (4) at the least, one or both of air for heating regeneration and treatment air are humidified by humidification means (7) and are allowed to pass through the respective zones, and then absorption and concentration performances can be improved. The absorption and concentration performances can be further improved when the honeycomb rotor (1) is divided into treatment zones (2, 3) and the regeneration zone (4) at the least, treatment target air is humidified by the humidification means (7) for treatment and is allowed to pass through the treatment zone (2), and part or all of the treatment air passing through the treatment zone (2) is allowed to pass through the treatment zone (3) again. |
