CARBON DIOXIDE CAPTURING DEVICE

Provided is a carbon dioxide recovery apparatus including a flue gas cooling unit that brings flue gas cooling water into contact with a flue gas to cool the flue gas, a circulation channel through which the flue gas cooling water that cools the flue gas and condensed water generated by cooling the flue gas are returned to the flue gas cooling unit, an absorption unit including a carbon dioxide absorbing section that brings the flue gas cooled in the flue gas cooling unit into contact with an absorbent and causes the absorbent to absorb carbon dioxide included in the flue gas, and a flue gas washing section that brings the flue gas including carbon dioxide absorbed in the carbon dioxide absorbing section into contact with flue gas washing water and washes the flue gas, a regeneration unit that removes carbon dioxide from the absorbent including carbon dioxide absorbed in the absorption unit, a supply channel through which circulating water circulating through the flue gas cooling unit and the circulation channel is guided as the flue gas washing water to the flue gas washing section, and a discharge channel through which the circulating water circulating through the flue gas cooling unit and the circulation channel is discharged to outside of a system.
