PROBLEM TO BE SOLVED: To reduce the energy required in the recovery of carbon dioxide by enhancing the energy efficiency of a whole carbon dioxide recovering system. SOLUTION: The carbon dioxide recovering system 2, which separates carbon dioxide in combustion exhaust gas from the combustion exhaust gas to recover the same, is equipped with an adsorbing part riser 20 wherein the adsorbant 6 fluidized in a combustion exhaust gas flow channel is reacted with the combustion exhaust gas 5A to adsorb carbon dioxide 7 in the combustion exhaust gas 5A by the adsorbent 6, a cyclone 30 for separating the adsorbent 6A having adsorbed carbon dioxide from the combustion exhaust gas 5B, a desorbing part riser 21 for heating the adsorbent 6A, which is separated by the cyclone to flow in a flow channel 25A, to carbon dioxide desorbing temperature to desorb adsorbed carbon dioxide, a cyclone 32 for separating carbon dioxide 7 from the adsorbent 6 and a transport pipe 33 for moving the separated adsorbent 6 so as to circulate the same between the adsorbing part riser 20 and the desorbing part riser 21. |
