Abstract

본 발명은 열교환기의 세정액으로 가성소다 수용액 또는 가성소다 수용액과 알콜 혼합용액을 세정액으로 사용하고, 이 세정액을 열교환기의 내부로 순환시키므로서 세정과정이 매우 용이하며 냉각효과면에서도 우수한 안수 냉각용 열교환기의 세정방법을 제공하고자 하는데, 그 목적이 있다.The present invention uses caustic soda solution or caustic soda solution and alcohol mixture as a cleaning solution for the heat exchanger and circulates the inside of the heat exchanger to facilitate the cleaning process. An object of the present invention is to provide a method for cleaning a heat exchanger.

상기 목적을 달성하기 위한 본 발명은 안수 냉각용 열교환기를 세정하는 방법에 있어서, 0.1∼0.4N의 가성소다 수용액을 세정액으로 사용하고, 상기 세정액을 열교환기에 순환시키는 안수 냉각용 열교환기의 세정방법에 관한 것을 그 요지로 한다.In order to achieve the above object, the present invention provides a cleaning method of an ordination cooling heat exchanger in which a caustic soda solution of 0.1 to 0.4 N is used as a cleaning liquid, and the cleaning solution is circulated to the heat exchanger. Let that point be about that.
