Zusammenfassung:A carbon dioxide capture system includes: a washing unit which uses cleaning water to clean absorption unit exhaust 5 gas or stripping unit exhaust gas; and a gas-liquid separation device which allows condensed water generated by cooling washing unit exhaust gas to be separated from the washing unit exhaust gas. The condensed water is mixed into the cleaning water by a condensed water line. If the amount of the cleaning 10 water becomes more than a predetermined amount, the cleaning water is mixed into an absorbing liquid by a cleaning water line. A controller controls a condensed water valve.
