PROBLEM TO BE SOLVED: To provide a carbon dioxide recovery apparatus that recovers carbon dioxide in exhaust gas exhausted from a cogeneration device by using adsorbent and supplies the carbon dioxide to a plant cultivation facility, and dehumidifies the plant cultivation facility.SOLUTION: A carbon dioxide recovery apparatus 1 that recovers carbon dioxide contained in exhaust gas exhausted from an internal combustion engine 22 which drives a power generator of a cogeneration device 10 and supplies the carbon dioxide to a plant cultivation facility 2, comprises: an adsorption tank 60 in which a first adsorbent 72 is housed； and a storage tank 62 in which a second adsorbent 74 is housed, in which exhaust gas is pressure fed to the adsorption tank, the carbon dioxide is adsorbed to the first adsorbent, the internal pressure of the adsorption tank is reduced to eliminate the carbon dioxide from the first adsorbent, the carbon dioxide is pressure fed to the storage tank and adsorbed/stored to/in the second adsorbent, the carbon dioxide stored in the storage tank is supplied to the plant cultivation facility, and air in the facility is circulated toward the apparatus through water component removing means for removing a water component in the exhaust gas.SELECTED DRAWING: Figure 1
