    1451400 Alkali metal chloride electrolysis ORONZIO DENORA IMPIANTI ELETTROCHIMICI SpA 30 Oct 1974 [30 Oct 1973] 18449/76 Divided out of 1451399 Heading C7B An alkali metal chloride solution is electrolyzed to produce an active chlorine compound, e.g. hypochlorite or chlonate, by passing the solution upwards in laminar flow through a plurality of vertically stacked electrolytic cell units so that electrolytically generated hydrogen bubbles increase in concentration towards the top so as to progressively increase the upward velocity of the electrolyte. Apparatus as described and claimed in Specification 1451399 is used.

    The invention relates to the field of electrochemical production, in particular to the design of electrolyzers for the production of chlorine-oxygen compounds. . A vertical diaphragm-free bipolar electrolyzer for producing oxygen-chlorine-oxygen-containing compounds is known, including a housing with a lid and a bottom, horizontal partitions placed in it along the height, with holes, fitted with grooves for installing electrodes. from the plates at the same distance and each electrode, except the extreme ones, enters the space between two adjacent ones. The electrolyzer in the lower part is equipped with a nozzle for the input of the electrolyte, and in the upper part - with a nozzle for the output of products. The disadvantage of this electrolysis is the low current efficiency. In order to eliminate this drawback, a vertical diaphragm-free bipolar electrolyzer for producing oxygen-oxygen-containing compounds is proposed, including, with a cover and a bottom, horizontal partitions with openings in it, on which electrodes are fixed at one end with one end, an electrolyte inlet pipe is placed, and in the upper part is a product outlet pipe, with the extreme partitions located at a distance from the cover and the bottom, the partitions are made of non-conductor The material and the holes are equally spaced from each other, while the other ends of the electrodes are passed through the holes of the aftermath of the partition and fixed to the next highest partition. Figure 1 shows the proposed electrolyzer, the cross section; figure 2 is a cross section along the line aa of figure 1; on fig.Z - electrolyzer, top view; in FIG. 4, a septum of non-conductive material with bipolar electrodes. The electrolyzer includes a housing 1, in which partitions 2 are placed along the height, made of a non-conductive material. The outermost partitions are placed from the lid 3 and from the bottom 4 at a distance and at the same time
    an input chamber 5 and an output chamber 6 are formed. The electrolyzer is equipped with anode and cathode current leads 7 and 8, respectively, for extreme monopolar electrodes. Bipolar electrodes 9 are fixed in electroconductive partitions 2. In the lower part of the electrolyzer there is a nozzle 10 for the inlet of the electrolyte, in the upper part a nozzle 11 for the outlet.
    Only the anodes are placed in the input chamber 5, cathodes are installed in the output b chamber, therefore no electrolysis will be observed in these chambers. The bipolar electrodes 9 are fixed in non-conductive partitions. The ends of the electrodes, opposite the fixed ends, pass through the openings 12 of the subsequent partition and are fixed on the next in. height of the septum.
    3 during the course of electrolysis, the electrolyte is fed into the input chamber 5, then it rises into the next chamber / formed by non-conductive partitions 2, from where it enters the next. The electrolyte flows in a longitudinal direction parallel to the electrodes; the resulting hydrogen bubbles do not stagnate and do not create gas inclusions. In separate compartments there is no recirculation space, therefore the hydrogen bubbles are dispersed into the electrolyte and rise with them upwards, as a result of which the lifting force of these bubbles is used to increase the speed of the electrolyte from
    the compartment to the compartment and thereby creating gradually increasing flow rates in the compartments in the upward direction.
    Due to a similar movement of the electrolyte, a decrease in the gas filling of the interelectrode space, the current efficiency increases, ceteris paribus.
