摘要
介绍高电流密度自然循环复极式离子膜电解槽改造为膜极距电解槽过程中,对阴极液循环系统进行化学清洗,消除铁离子富集在阴极网造成的槽电压升高。
During the transformation of high electrolyzers with natural circulation into ion-exc current density bipolar type ion-exchange membrane hange membrane electrolyzer with membrane interpolar gap, the circulation system of cathode liquor was cleaned by chemical method to avoid cell voltage raising caused by iron ions being deposited on cathode net.
