Definitions

  • electrolytic cells it is often of importance to make the spacing of anode and cathode as small as possible in order to reduce the voltage drop and hence the power consumed.
  • gas is produced at an electrode, it is of importance for the economy of the process that the gas is removed from the surface of the electrode and replaced by fresh liquid as quickly as possible.
  • the present invention relates to electrodes for electrolytic cells of the kind in which no deposition is taking place at the electrode concerned, but in which gas is developed at the electrode inside a diaphragm separating the anode and cathode compartments, which gas is collected in a hood above the electrode, and it is an object of the invention to achieve in this connection the aims above referred to in a particularly effective and simple manner.
  • the invention primarily consists in that the electrode is provided on both sides with low projections distributed over its surface and having a small top surface on which the diaphragm bears, and the resulting interstice below the liquid surface cormnunicates both near the top and near the bottom of the electrode with a liquid reservoir provided in the electrode under the hood, so that the produced gas rising in the interstice and entering the reservoir at the top, causes a circulation of the fluid upwards in the interstice and downwards in the reservoir.
  • Fig. 1 is a view in vertical cross-section of an anode according to the invention, placed in an electrolytic cell,
  • Fig. 2 is a fragmentary view of the anode in horizontal cross-section
  • Fig. 3 is a fragmentary front view of the anode without diaphragm and partly in section as indicated by the line IIIIII in Fig. 2.
  • the anode comprises a pair of parallel plane walls I mutually propped by suitably spaced cross-walls 2 and connected, at the top, to a positive pole 3 and closed by a rubber hood 4 for collecting oxygen gas which is separated at the anode by the reaction 2SO4+2H2O 2HzSO4+Oe.
  • the anode compartment is confined by a diaphragm 5, which is drawn tightly onto the anode like a bag and extends upwards into the rubber hood 4, in which it projects above the surface of both the anode and the cathode liquids contained in the electrolytic vessel, in which each anode is placed upright on a ledge 6 at a distance above the bottom I, so that the vessel forms a communicating cathode compartment for all the individual cells.
  • the adjacent starting cathodes of sheet iron are indicated on both sides at 8 in Fig. 1.
  • both walls I are provided, over their entire width, with shallow vertical ribs 9 of triangular cross-section, against which the diaphragm bears, partly because it is drawn taut onto the anode body I, 2 and partly by so controlling the flow of ferrous sulphate solution to the cathode compartment and of sulphuric acid solution from the anode compartment that the catholyte will have a higher static pressure than the anolyte and thereby exert a pressure on the diaphragm from outside.
  • the hollow space within the anode will form a reservoir for anolyte.
  • the oxygen gas is separated off at the anode surface under the diaphragm 5 and rises through the channels In from which it passes through the passages ll into the interior anode space, in which it rises further so as to be collected above the liquid within the hood 4.
  • the gas will entrain anolyte, so that a constant flow of anolyte will be maintained, which passes upwards through the channels Ill, then through the passages ll into the interior anode space, downwards through the latter and, through the notches I2, again out into the channels it, whereby the anolyte within these channels will constantly be renewed and, at the same time, the upward liquid flow within the channels It will cause immediate removal of the oxygen gases from the anode surface according as they are formed.
  • An electrode structure for electrolytic cells having a hood arranged at the top of the cell, said electrode structure comprising a plurality of vertically disposed wall members which are electrically conductive, said wall members being spaced apart and integrally connected forming a reservoir open at the top and bottom for receiving electrolyte, a plurality of vertically extending ribs on the outer surfaces of said wall members, a' diaphragm disposed about said Wall members, a resilient hood embracing the upper portion of said walls and securing said diaphragm in place and disposed against said ribs, said walls having passageways therethrough in the upper part of each wall for the passage of gas from the outer surface of said walls into the space between the walls and upward into said hood, said walls having notches along the bottom edges thereof to provide passageways for electrolyte.
  • each wall member wherein said passageways in the upper part of each wall member are spaced vertically and are upwardly inclined through the walls.
