Abstract

본 발명은 과망간산칼륨 수용액을 흡수액으로 하는 질소산화물 제거 흡수탑에 고착된 고형 물질을 용해시키는데 있어서 황산과 과산화수소의 혼합수용액을 세정제로 사용하는 것을 특징으로 하는 질소산화물 제거 흡수탑에 고착된 고형물질의 제거 방법에 관한 것이다.The present invention uses a mixed aqueous solution of sulfuric acid and hydrogen peroxide as a cleaning agent to dissolve a solid substance fixed in a nitrogen oxide removal absorption tower using an aqueous solution of potassium permanganate as an absorption liquid. It is about a method.
