CARBON DIOXIDE CAPTURING APPARATUS CAPABLE OF INHIBITING VOLATILIZATION OF ABSORBENT IN CARBON DIOXIDE CAPTURING PROCESS

摘要

The present invention relates to a carbon dioxide capturing apparatus. More particularly, the present invention relates to a carbon dioxide capturing apparatus, comprising: an absorption tower into which an absorbent liquid including a carbon dioxide absorbent and exhaust gas containing carbon dioxide are supplied such that the absorbent liquid and the exhaust gas containing carbon dioxide may flow in the same direction, in which the carbon dioxide from the exhaust gas containing carbon dioxide is absorbed by the absorbent liquid, and which discharges the carbon dioxide that is contained in the absorbent liquid and exhaust gas from which the carbon dioxide has been removed; an absorption tower cleaning end arranged at the top of the absorption tower so as to absorb the volatilized absorbent of the absorbent liquid using cleaning water and absorb the carbon dioxide remaining in the exhaust gas from which carbon dioxide was removed and which was discharged from the absorption tower; a regeneration tower for vaporizing, by means of heating, carbon dioxide from the absorbent liquid containing carbon dioxide that was discharged from the absorption tower, and separately discharging the vapor-phase carbon dioxide and the absorbent liquid and regenerating the absorbent liquid; and a regeneration tower cleaning end arranged at the top of the regeneration tower so as to absorb the carbon dioxide that was discharged from the regeneration tower and the volatilized absorbent from the regenerated absorbent liquid using cleaning water.
