Definitions

  • the present invention relates to an electrolytic cell, particularly adapted for electrolyzing alkali chloride solutions, and has for its purpose to attain a cell of high current capacity which at the same time occupies little space and is cheap to build.
  • rIhe invention is based on the cell type, well known in the art of electrolyzing alkali chloride solutions, in which a permeable cathode lo consisting of perforated sheet-metal, wire gauze and the like with a diaphragm adjacent to the cathode forms a container for the solution to be electrolyzed, in which container the anode or a row of anodes is placed.
  • a number of electrolyzing units or sets each consitingof cathode, diaphragm and anode are installed in one and the same outer container for the electrolyte emerging from the permeable cathode and for the hydrogen formed during electrolysis.
  • all the electrolyzing units are connected in parallel and the result is a cell of very high current capacity, which occupies very little space relatively to its capacity as compared with previous constructions7 in which each electrolyzing unit vconstitutes a separate cell.
  • More over the new cell is far cheaper to construct because a large number of partitions for the individual electrolyzing units are dispensed with and the several units ma y be placed much closer to one another.
  • Figs. 3 and 4 show plan views of the outer containers according to Figs. 1 and 2 respecl tively.
  • each electrolyzing unit is composed of the cathode c of perforated sheet-metal, wire gauze or the like, a diaphragm -con the inside. of the cathode and forming together with the latter 5o the trough-like container for the electrolyte,
  • the cell shown in Figs. 2 and 4 differs from that represented by Figs. 1 and 3 mainly by its having the electrolyzing units constructed as double-units, the cathode and the diaphragm forming two troughs located side 'by side and containing two anodes or two rows of anodes.
  • troughs -e For suspending these electrolyzing units in the common container -Z)- there are provided troughs -eextending along the upper edge of the container.
  • the troughs -eon two opposite sides of the container communicate by means of similar but somewhat broader troughs
  • the troughs eand -fform liquid-seals in which the electrolyzing units are suspended by means of a trame of angle iron extending along the whole periphery of the unit and vserving as fastening device for the cathode and the diaphragm and as support for the cell top and the anodes, said angle iron resting upon its turned-down flange in the troughs -eand
  • a cell for electrolyzing solutions of alkali chlorides comprising an outer unsubdivided tank for the electrolyzed liquid and the hydrogen, a trough for sealing liquid at the top of the tank on all its sides and trough extending across the tank andconnected to the afores
