Abstract
In an apparatus for electrolyzing an aqueous solution, which includes a plurality of electrolytic cells disposed at a plurality of vertically spaced levels and divided by partitions from one another, each of said cells having at least one anode and at least one cathode, said cells including an uppermost cell having an inlet for said solution, and a lowermost cell having an outlet for said solution, the improvement wherein: PA1 (a) each cell being separated into at least two horizontally adjacent cell units; PA1 (b) the separation adapted to direct the solution flow from the top of one unit into the bottom of the adjacent unit enabling solution flow successively through each unit; PA1 (c) a last unit of each cell provided with a passage extending from the top of the last unit to the bottom of the unit at a lower level to direct solution flow downwardly; PA1 (d) the anode and cathode being vertical in each unit opposite each other forming a bipolar electrode assembly; and PA1 (e) each unit with a gas collecting zone above the anode and cathode and with a gas riser extending from a partition defining the bottom of each unit to the collecting zone with another end of the gas riser exte…
