    The invention relates to the technology of electrochemical production, in particular to electrolyzers for producing chlorine and alkali metal hydroxide solution.
    The purpose of the invention is to reduce power consumption by creating an optimal current distribution over the surface of the electrodes.
    Fig, 1 shows two cells of the electrolyzer; in fig. 2 - flat electrode.
    The cell of the electrolyzer consists of an electrically conductive body consisting of two halves 1 and 2 connected
    using frame sealing 3, between which membranes 4 are placed, flat electrodes (anode 5 and cathode 6) and elements 7 for supplying current to them are placed in each half of the body, contact tires 8 and 9 are placed on the outer side of the body,
    When several cells are connected to each other by means of the known fixture means, the cells are conductively connected to adjacent cells by contact tires 8 and 9. Electric current flows into the anode 5 from the contact bus 8 through the bottom and the stiffening elements. After passing through the membrane 4

    the current flows into the cathode 6E flows through the stiffening elements into the other bottom of the half-shell and then into the contact bus 9 of the same cell, after which it passes into the contact bus 3 of the next cell.
    FIG. 2 shows a contact bus 8 (or 9), as well as an electrode 5 (or 6), made in the form of blinds
    With this arrangement of the electrodes, the electrolyte and the gas formed during the electrolysis can easily flow into the space between the electrodes and be removed from the latter. If necessary, one or several spacer elements 31 can be positioned in front of the electrode, i.e., the anode or cathode. These distance elements should not be positioned vertically on a part or all of the electrode height.
    On the electrode (anode 5 or cathode 6) there are sections without holes. The reverse side of these sections is electrically conductively fixed on the elements of a rigid type according to FIG. 2. Contact tires 8 or 9 are located at the bottom of the half-shell in the same plane as the metal stiffeners. Such an arrangement minimizes the current transfer and its path from the contact bus to the electrode, minimizes the current density in the conductive elements and provides the possibility of an optical current distribution in the electrode. In addition, the proposed design allows to reduce the current losses in the cell or throughout the cell as much as possible. installation.
    The shape of the electrodes made, for example, of a perforated lattice 3 with rhombic holes or thin-sheet constructions with louver holes, as well as their location in the cell, allow easy passage of the gases produced during the electrolysis process; space behind the electrodes. With such a discharge of gases from the electrode space, the resistance of the gases decreases and the pressure on the cell decreases.
    Half shell can be made; iron, iron alloy or anode material, half of the shell on the anode side must be made of chlorine-resistant material,
    As a partition using traditional ion-exchange membranes,

    For example, from tetrafluoroethylene copolymer and sulfonic acid perfluoroether, the ion exchange membrane prevents hydrogen from being mixed with chlorine, and its selective permeability allows only alkali metal ions, i.e., to pass into the cathode space. the transition of halogen-Q nids into the cathode space and the entry of hydroxyl ions into the anode space are avoided.
    The electrolyzer can contain as many as 15 single cells, as well as a large number of cells connected in parallel, while the electrical contact is made through a conductive bus,
    The proposed technical solution allows usb-5 znt electricity consumption in the production of chlorine and alkaline metatl hydroxide as by reducing ohmic losses in the current-carrying parts of the electrolyzer, and by uniformly distributing the current density over the surface of the electrodes and the ion-exchange membrane.
