摘要
第1期和第2期氯工程电解槽共用盐水供应系统,在操作条件均相同的情况下,第2期电解槽电压比第1期高。从盐水品质、开停车、操作方法、离子膜等多角度,结合电压变化曲线进行分析,结论是:第2期电解槽电压高是第2期离子膜电解槽阴极活性涂层的变化引起的。
The first-stage and the second-stage electrolyzers of Chlorine Engineering Co. used the same brine system but the cell voltage of the second-stage was higher than that of the first-stage at the same operation conditions. On the basis of analysis of many aspects such as brine quality, start-up and shutdown, operation methods and ion-exchange membrane, and on the basis of combination of the curve of voltage change, the causes of high-cell voltage of the second-stage electrolyzers were found. The cause was the change of cathode active coating of the second-stage ion-exchange membrane electrolyzers.
