Definitions

  • the invention relates to a monopolar electrolytic filter press cell which is suitable for the electrolysis of an aqueous, halide-containing electrolyte (brine) in order to produce an aqueous alkali metal hydroxide solution (cell liquid) and halogen and hydrogen.
  • the cell consists of the two end pressure plates with tension anchors, a large number of alternately arranged anolyte and catholyte chambers, the electrolyte chambers, each made up of two anode and cathode plates, each separated by a flat ion-permeable element, the membrane.
  • an electrolytic membrane cell which, in the manner of the filter press cells, consists of a large number of anode and cathode plates lined up with intermediate membranes and spacer plates.
  • the anode and cathode plates according to the invention also have a non-conductive part which is provided with passages for the formation of channels for the supply and discharge of the process media.
  • the process media flow from the channels into the electrolyte chambers or from the electrolyte chambers into the channels via specially corrugated passages.
  • the thickness of the spacer plates between each membrane and anode plate or cathode plate defines the intended distance between two membranes.
  • the membrane cell described is characterized by a large number of different components with a large number of sealing points.
  • the invention has for its object to reduce the variety of different elements and thus the variety of sealing points.
  • the advantages achieved by the invention are, in particular, that the number of components is significantly reduced, so that the number of sealing points also and that the cell can be easily manufactured and assembled.
  • Anode plate 1 and cathode plate 2 are metal plates made of different materials and have an openwork, finely divided, ie . H. for liquid and gas permeable structure.
  • the non-active part 6 is not broken, but dense, except for the at least four passages 7, 8, 9 and 10 for the process media brine, cell liquid, halogen and hydrogen.
  • the electrolytically inactive part of the plates still has the current conducting part 1 for the connection of the current-carrying elements.
  • the membrane 3 between the plates 1 and 2 prevents electrical contact between the two plates and creates the reaction spaces for the brine and the cell fluid.
  • the material of the membrane 3 is any suitable cation exchange material with appropriate storage or coating.
  • the seals 4 are usually made of an elastomeric material, such as. B. natural or synthetic rubber.
  • the seal 4 receives four passages 14, 15, 16 and 17 with transverse bores 18, 19 to the corresponding reaction spaces in a known manner.
  • the electrolysis cell is assembled in a known manner with the aid of end plates and tie rods, the end plates themselves being able to be inactive or already as an anode or cathode Act.
  • the alternating series of a plurality of two anode plates, which form the anolyte chambers 12, the membrane and the two cathode plates, which form the catholyte chambers 13, form the monopolar electrolytic filter press cell.
  • the passages in the plates in combination with the seals between the plates and around the inner edges of the plates, form the individual channels for the process media.
  • the passages 7 in the lower part of the plates form the channel 20 for the supply of the brine into the cell and, via the transverse bore 18, the transmission into the anolyte chamber 12.
  • Cell liquid is formed via the channel 21, which is formed by the passages 8 with the corresponding seals and is connected to the catholyte chambers via the transverse bore 19.
  • halogen is discharged together with used brine and hydrogen with alkali metal hydroxide.
  • the seals 4 around the chambers and channels are such that, on the one hand, they act absolutely tight against the other cell part and, on the other hand, do not create any electrical contact between the anode and cathode plates.
  • the inventive design of plates, membranes and seals consequently create the electrolyte chambers and the channels with the necessary open connections to one another.
  • the non-active part 6 of the anode and cathode plates can be bent plane-parallel and offset from the active part 5. This ensures that the seal 4, e.g. as double U-shaped, approximately the same thickness sealing lips or webs.
