  • the asbestos slurry-type diaphragm has an important advantage in the cells inasmuch as the diaphragm conforms to the convoluted contours of the cathode and presents no attachment problems.
  • the cathode fingers are particularly fabricated from wire screen mesh so that the asbestos diaphragms can be deposited on the cathode from the asbestos slurry.
  • the use of other types of asbestos such as asbestos paper wrapped over the finger-type cathode and sealed at the top and bottom with cement and putty provide a poor seal and loss of current efficiency.
  • a diaphragm-type cell for the production of chlorine and caustic from aqueous alkali metal chloride solutions having a plurality of anodes mounted at the bottom of said cell, a cathode between adjacent anodes and spaced between each cathode and anode a diaphragm which divides the cell into anolyte and catholyte compartments the improvement which comprises:

  • FIG. 4 is a side cross-sectional view of the conventional diaphragm electrolytic cell wherein an optional modification of the invention has been installed.
  • the present invention is installed in a typical electrolytic diaphragm cell having cell bottom and bus bar means 10 which is coated a nonconductive sealant layer 12 and through which sealant layer 12 protrudes a series of spaced anode metal stems 40 for connecting anodes 24 with bus bar means 10.
  • the stem 40 is secured to the bus bar means 10 by use of nut 42.
  • the cell is completed with the installation of cell sides 16 and cell top 14 along with weak cell liquor outlet 18, hydrogen outlet 20 and chlorine outlet 22, the exact positioning of the foregoing outlets being a matter of choice.
  • the porous cathode 26 is typically made of a ferrous metal with a woven wire construction although other means of fabricating can be employed.
  • the cathode 26 is so formed that it will be one continuous piece but containing a series of openings or passageways through which the anodes 24 can pass and most of the surface of cathode 26 will be parallel to the anodes 24.
  • the cathode 26/diaphragm 36 assembly can be prepared prior to insertion of diaphragm 36 into the cell.
  • each of the continuous sheet or endless belt diaphragm 36 to the lower diaphragm support 30, then lowering the cathode 26 down onto the lower diaphragm support 30 so that the diaphragm 36 extends upwardly through the passageways previously provided for the anode 24 and, thereafter, applying the upper diaphragm support 32 to the other edge of the endless band diaphragm 36.
  • This assembly is then set into the cell so that the anode 24 extends through the passageways made by the diaphragm 36 which parallels the passageways of the cathode 26.
  • the cathode 26 and lower diaphragm support 30 are then placed in mechanical and electrical attachment with the cell so that proper position of the cathode 26 and diaphragm 36 will be maintained.
  • Gas seals (not shown) between sidewall 16 and lower diaphragm support 30 and between sidewall 16 and upper diaphragm support 32 complete the separation between the cathode and anode chambers.
  • FIG. 3' The invention is illustrated schematically in FIG. 3'
  • the expanded drawing shows an anode 24 embedded in cell bottom and extending through the nonconductive sealant layer 12.
  • the lower diaphragm support 30 contains slots or openings which accommodate the insertion of anode 24.
  • the cathode 26 is of woven wire-mesh construction and is so woven that it has openings shaped corresponding to the openings or slots in the lower diaphragm support 30 but of a slightly larger nature thereby accommodating the endless belt diaphragm 36 which is attached to the lower diaphragm support 30 and the upper diaphragm support 32 which has the same configuration as the lower diaphragm support 30.
  • the lower diaphragm support 30 and the upper diaphragm support 32 are constructed of a chemically inert, electrically non-conducting thermoplastic material such as polyolefin derived form an olefin containing 2 to 4 carbon atoms including polyethylene, polypropylene, polybutene-l and mixtures thereof; polytetrafluoroethylene, copolymers of tetrafluoroethylene and polyperfluoroalkoxy compounds, chlorofluoropolyethylene, polyvinylidene fluoride polymers and acrylonitrile butadiene styrene terpolymers.
  • a chemically inert, electrically non-conducting thermoplastic material such as polyolefin derived form an olefin containing 2 to 4 carbon atoms including polyethylene, polypropylene, polybutene-l and mixtures thereof; polytetrafluoroethylene, copolymers of tetrafluoroethylene and polyperfluoroal
  • the properties of these polymers are improved by adding inert, non-conducting yet reinforcing fillers such as asbestos, glass fibers, mica, kaolin or carbon black.
  • An exemplary composition for use in this invention is an asbestos filled polypropylene composition, e.g., as disclosed in British Patent 1,246,034, which for the sake of brevity is incorporated herein by reference.
  • Another equally suitable material is a polytetrafluoroethylene polymer or copolymer.
  • the upper diaphragm support 32 and the lower diaphragm support 30 are made from the foregoing polymeric materials in such a manner that the support members 30, 32 are both electrically non-conducting and are incapable of permitting the flow of electrolyte from one chamber to the other chamber. It is also within the scope of this invention to make the support frames 30, 32 out of a suitable metal or wire which is completely covered and encased with an insulating polymeric material disclosed above.
  • the endless belt diaphragm 36 can be made out of the same polymeric material as the diaphragm support members 30, 32 are made out of or it can be one of the other suitable polymeric materials, e.g., those enumerated above.
  • the endless belt diaphragm 36 is so fabricated with appropriate physical, chemical and electrochemical properties that it is porous and will permit the flow of electrolyte from one chamber to the other chamber.
  • the endless belt diaphragm 36 is attached to the diaphragm supports 30, 32 in any one of several conventional techniques used in fabricating polymeric objects such as heat-sealing, cementing or friction fit snap-in techniques.
  • the diaphragm 36 can be heat-sealed to the lower or bottom support 30 and mechanically, i.e., friction fitted, to the upper diaphragm support 32.
  • the fabricated diaphragm 36 may properly be classified as a porous membrane, or a felted fabric such as are presently employed in the various phases of electrolytic cell technology. It is also known in the cell technology to insert between diaphragm 36 and the electrodes, either or both anode 24 and cathode 26, an inert screen (not shown) to facilitate and improve the functioning of the cell. This modification can be used in conjunction with the present invention, if desired.
  • the anode 24 can be either a solid metal sheet, a woven wire arrangement or an expanded metal mesh as desired, the exact configuration of the anode 24 being beyond the scope of the present invention.
  • the anode 24 is made of a valve metal and, thereafter, coated.
  • a valve metal it is meant metal of tungsten, titanium, zirconium, tantalum and niobium.
  • titanium or tantalum is employed and it is normally a commercially pure grade such as electrolytic grade. Alloys of valve metals can be employed as long as the alloy meets the criterion of passivity, metal alloys which become passivated when polarized anodically and can remain passive well beyond anodic potential needed to convert a chloride ion to chlorine.
  • platinum group metal or metal compound e.g., oxide
  • the platinum group metals include platinum, ruthenium, osmium, rhodium, iridium and palladium and alloys of two or more of the foregoing metals.
  • Many means for applying and the formulations of platinum group metals and compounds for these coatings are known, for instance, see US. Pat. Nos. 3,632,498; 3,630,768; 3,616,446; 3,242,059; and 3,177,131 which for the sake of simplicity and brevity are herein incorporated by reference.
  • FIG. 4 shows an optical modification of the present invention which is designed to secure the benefits of the present invention to the diaphragm cell equipped with the conventional Hooker woven wire cathode employed therein.
  • the Hooker woven wire type cathode is well known in the art and generally disclosed in the Sconce textbook discussed above in the background section.
  • the cell bottom and bus bar 10 the nonconductive sealant layer 12 and anodes 24 with metal stem 40 and retaining nut 42 remain positioned without change as shown in FIG. 1.
  • the continuous sheet or endless belt diaphragm 36, the lower diaphragm support 30 and upper diaphragm support 32 are rearranged so that they form a series of equal distance-spaced closed openings on both sides. This is accomplished by attaching the endless belt diaphragm 36 to the anode 24 openings of the lower diaphragm support 30 as previously disclosed.
  • the upper diaphragm support 32 is now realigned so that the prior axial alignment of the openings in the lower diaphragm support 30 and the openings in the upper diaphragm support 32 are completely out of register. From a top view the openings in the upper support 32 are now spaced equidistant from each two adjacent openings in the lower support 30.
  • the cathode 26 is not encased by the diaphragm 36 and diaphragm supports 30, 32 and can be disengaged from the diaphragm 36 without disassembly of the diaphragm 36 diaphragm supports 32, 30 arrangement.
