一级除盐系统重复再生原因分析

CAUSE ANALYSIS OF NEEDING REPEAT REGENERATION IN THE PRIMARY DESALTING SYSTEM

分析沙角发电C厂化学水处理一级除盐系统经常出现重复再生才能投入运行的情况 ,认为阳床的阳离子交换树脂再生时受到再生剂中铁的污染 。

Events often occurred in the primary desalting system of chemical water treatment facility, which can be put into operation again only after repeat regeneration, at Shajiao C Power Plant have been analysed. It is considered that the cation exchange resin in the cation bed was polluted by iron contained in regenerative agent during the time of regeneration. After replacing cation exchange resin and adopting top quality regenerative agent, the said problem has been solved.
