Abstract
An energy efficient and durable thermal swing type carbon dioxide recovery and concentration device can be made smaller and use low-temperature heat waste of 100° C. or less. A honeycomb rotor carries adsorption particles having a sorption capacity for carbon dioxide. The rotor is rotated in a sealed casing divided into at least an sorption zone and a desorption zone and is brought into contact with material gas that contains carbon dioxide in a state wherein the honeycombs in the sorption zone are moist so as to adsorb the carbon dioxide while carrying out evaporative cooling of water. Then, the honeycombs that have adsorbed the carbon dioxide are moved to the desorption zone and brought into contact with low pressure vapor so as to desorb high concentration carbon dioxide. Thus, it is possible to continuously recover carbon dioxide at a high recovery rate and high concentration.
