Research on pH Automatic Adjustment System in Radioactive Decontamination Waste Liquid Evaporation Treatment System

摘要: 废液蒸发处理系统在使用过程中曾出现上料废液pH值不稳定,导致蒸发器液位剧烈波动。对这一问题进行原因分析,探讨在上料管路中增设一套废液pH值自动调配系统来实现在线实时监测和自动调配上料废液pH值的技术方案,设计相应技术方案的工艺流程。该方案通过自动添加适量的酸或碱溶液,可以使上料废液pH值始终稳定在要求范围内。

Abstract: During the operation process of the waste liquid evaporation treatment system,the pH value of the radioactive decontamination waste liquid will change constantly,and lead to the violent fluctuation of the liquid level in the evaporator.In the paper,the causes of this phenomenon are analyzed,and the technical solution for this problem which introduces a waste liquid pH value online monitoring and automatic adjustment system into the waste liquid loading pipeline is designed.By adding suitable amount of acid or alkali solution automatically into the loading waste liquid,its pH valve can be stabilized within the given range.
