Kind Code:
A1
Abstract:
The present invention relates to an exhaust gas cleaning liquid purifying system and, more specifically, to an exhaust gas cleaning liquid purifying system comprising: a scrubber for removing contaminants such as sulfur oxide from exhaust gas by using a cleaning liquid; a cleaning liquid purifying portion for purifying the contaminated cleaning liquid discharged from the scrubber; a cleaning liquid re-supply portion for re-supplying the cleaning liquid purified by the cleaning liquid purifying portion to the scrubber; and a sludge processing portion for processing and storing sludge discharged from the cleaning liquid purifying portion, wherein the cleaning liquid purifying portion comprises: a circulation buffer tank for temporarily storing the contaminated cleaning liquid discharged from the scrubber; a coagulant supply device for supplying a coagulant for coagulating contaminants in the contaminated cleaning liquid discharged from the scrubber; a precipitating device for holding the contaminated cleaning liquid discharged from the scrubber for a predetermined period of time such that contaminants are precipitated, thereby primarily purifying same; and a filtering device for filtering out contaminants from the contaminated cleaning liquid, thereby secondarily purifying same.
