Abstract
Изобретение относитс к конструкци м электролизеров и позвол ет увеличить степень регенерации и снизить расход электроэнергии. Указанна цель достигаетс в электролизере дл регенерации серно-кислых травильньк растворов, включающем корпус, нераст- воримьш свинцовый анод и катод, раз- деленные анионитовой мембраной, патрубки подвода рабочих растворов и отвода продуктов реакции, причем катод выполнен из алюмини . 1 табл.The invention relates to the design of electrolysis cells and allows an increase in the degree of regeneration and a reduction in power consumption. This goal is achieved in an electrolytic cell for the regeneration of sulfuric acid pickling solutions, including a housing, an insoluble lead anode and a cathode, separated by an anion-exchange membrane, working solution supply connections and removal of reaction products, the cathode made of aluminum. 1 tab.
Description
