Zusammenfassung:The present invention relates to a resource circulation system, which allows efficient reuse of resources such as carbon dioxide absorber, comprising: a pretreatment unit which receives exhaust gas from an exhaust gas emission source and removes pollutants from the exhaust gas; a desulfurization unit which receives the exhaust gas from the pretreatment unit, removes sulfur oxides from the exhaust gas, and discharges the exhaust gas; a carbon dioxide absorption tank which receives the exhaust gas from a front end or rear end of the desulfurization unit, removes carbon dioxide and sulfur oxides from the exhaust gas by reaction with a carbon dioxide absorber, and discharges the treated gas; a primary precipitation tank which receives a reaction solution from the carbon dioxide absorption tank and precipitates foreign matter by coagulation with a coagulant; a secondary precipitation tank which receives the reaction solution from the primary precipitation tank, produces calcium carbonate by reaction with calcium oxide, and simultaneously removes carbon dioxide captured from the reaction solution to regenerate the carbon dioxide absorber; a receiving tank which receives the calcium carbonate from the secondary precipitation tank and stores the same; and a regenerated carbon dioxide absorber storage tank which receives the regenerated carbon dioxide absorber from the secondary precipitation tank and circulates the same to the carbon dioxide absorption tank. 본 발명은 배기가스 배출원에서 배출되는 배기가스를 유입받아 배기가스로부터 오염물질을 제거하는 전처리부; 상기 전처리부에서 배기가스를 유입받아 배기가스로부터 황산화물을 제거하여 배출하는 탈황부; 상기 탈황부 전단 또는 후단에서 배기가스를 유입받아 이산화탄소 흡수제와 반응에 의해 배기가스로부터 이산화탄소 및 황산화물을 제거하고 처리가스를 배출하는 이산화탄소 흡수조; 상기 이산화탄소 흡수조로부터 반응액을 유입받아 응집제와 응집반응에 의해 이물질을 침전시키는 1차 침전조; 상기 1차 침전조로부터 반응액을 유입받아 산화칼슘과 반응시켜 탄산칼슘을 생성함과 동시에 반응액으로부터 포집된 이산화탄소가 제거됨에 의해 이산화탄소 흡수제가 재생되는 2차 침전조; 상기 2차 침전조로부터 탄산칼슘을 전달받아 저장하는 수득조; 상기 2차 침전조로부터 재생된 이산화탄소 흡수제를 전달받아 상기 이산화탄소 흡수조로 순환시키는 재생 이산화탄소 흡수제 저장조;를 포함하는 것을 특징으로 하는 자원순환 시스템에 관한 것이다.
