Definitions

  • the present invention relates to improvement in cells for the electrolysis of aqueous saline so-' to keeping the bath voltage as low as possible, it
  • the present invention aims at providing an apparatus for the electrolysis i aqueous solutions of sodium sulphate by the amalgam process, which has horizontally disposed electrodes and diaphragm which is free from the foregoing drawbacks, by virtue of the anode being located below,
  • the diaphragm, '0 the mercury being separated from the diaphragm by allowing it to flow in suitably designed channels of electrically insulating and chemically resistant material, superposed directly on the dia- Phras I with a view to lowering the bath voltage
  • the anode is preferably in sheet form and preferably also of corrugated cross section, the channels containing the mercury being located in the troughs of the corrugations.
  • This arrangement enables the diaphragm to be laid directly on and to fol- 5 low the curvatureoi the undulating anode, the corrugations of which are preferably sinusoidal in form.
  • the anode is perforated to enable the anolyte'to pass therethrough into a collecting chamber beneath it.
  • Fig. 1 is a top plan view
  • Fig. 2 is a cross section along the line o-b of Fig. l:
  • I denotes a vat having a bot tom outlet 2 for the anode liquor.
  • a perforated lead anode 3 Horizontally disposed in the lower part of said vat I is a perforated lead anode 3.
  • a diaphragm 4 of asbestos paper is laid directly on the anode and is in turn covered by a slotted framework comprising a series of troughs 5 which framework is stamped out of corrugated sheet iron and is covered with a 2 mm. layer of hard rubber.
  • the space between the middle of adjacent troughs is 60 mm.
  • Thetroughs oi the corrugations serve as channels for the mercury forming the cathode which "is admitted at 6 and issues, in
  • the electrolyte consisting of sodium sulphate solution is denoted by 8.
  • the mercury surface of the cathode is freely accessible.
  • a cell for the electrolysis of aqueous saline solutions, by the malgam process comprising a container, a substantially horizontally disposed diaphragm, an anode disposed below said diaphragm, electrically insulating and chemically resistant means for conducting a liquid, disposed above said diaphragm, and mercury serving as a cathode contained in said means, said means being so disposed and so constructed as to allow. passage of the electric current between said mercury cathode and said anode;
  • a cell for the electrolysis of aqueous saline solutions, by the amalgam process comprising a container, a substantially horizontally disposed diaphragm, an anode disposed below said diaphragm, at least one substantially horizontally disposed trough-shaped channel of electrically insulating and chemically resistant material superposed directly on the diaphragm and out of contact with the walls of said container along its length, and mercury serving as a cathode contained in said trough-shaped channel.
  • a cell for the electrolysis of aqueous saline solutions, by the amalgam process comprising a container, a substantially horizontally disposed corrugated anode provided with perforations, superposed thereon a diaphragm or pliable material, a plurality of trough-shaped channels of electrically insulating and chemically resistant material disposed in and resting on the troughs formed by the corrugations of said diaphragm,
  • mercury serving as a cathode contained in said trough-shaped channels.
  • a cell for the electrolysis of aqueous saline solutions, by the amalgam process comprising a container, a substantially horizontally disposed corrugated anode provided with perforations, superposed thereon a diaphragm oi pliable material, a plurality of trough-shaped channels of corrugated sheet iron stamped to shape and provided with 'a coating of hard rubber disposed in and resting on the troughs formed by the corruas a cathode contained in said trough-shaped gations of said diaphragms', and mercury serving ⁇ 2 channels. 5
