Definitions

  • the invention relates to an electrolytic cell block consisting of a plurality of electrolytic cells arranged one behind the other, each electrolytic cell having two plate-shaped electrodes parallel to one another in a cell trough and a membrane parallel to these being arranged between adjacent electrodes, and the cell troughs each consisting of four, the electrodes and membranes between receiving profile plates which form electrolyte space halves are constructed and the profile plates of the cell troughs are clamped to one another in pressure-tight manner with two parallel end block plates arranged on the end face.
  • the invention is therefore based on the object of creating an electrolytic cell block of the type mentioned at the outset in a modular construction in which the membranes remain in their original position.
  • the profile plates are designed as injection molded parts with integrated membrane support grids and with clamping ribs and associated clamping grooves for holding the membranes and are arranged together with the block end plates in a block frame.
  • the invention is based on the knowledge that the membrane is not sufficient for reliable membrane fastening only to be clamped smoothly at the edge. Rather, the clamping ribs / clamping grooves mentioned are required in connection with the block frame bracing. In addition, the invention makes use of the knowledge that even this is still not sufficient to keep the membrane parallel to the electrodes. This can only be achieved with the membrane support grids integrated in injection molded parts.
  • the advantages achieved by the invention can be seen in the modular design, which allows simple adaptation to capacity requirements by removing or adding individual cells.
  • the compact design results in a significantly smaller space requirement, which results in greater ease of maintenance.
  • the profile plates can be produced more easily and at lower costs than conventional welded structures. Since the distances between the electrodes are smaller than before, the power consumption is low and the capacity is high.
  • the profile plates can also be optimally designed with regard to the hydraulic flows in the individual cells, so that there is also a high process yield.
  • a hydraulic tension e.g. B. with the help of at least one hydraulic cylinder piston assembly, but is also possible.
  • one block end plate is fixed and the other block end plate is mounted in the block frame so that it can be moved in parallel. In any case, it is advisable to provide the fixed block end plate with electrolyte supply and drain connections.
  • the electrolytic cell block shown in the figures consists of several electrolytic cells 1 arranged one behind the other.
  • Each electrolytic cell 1 has two plate-shaped electrodes 2, 3 (anode 2, Cathode 3) in a cell trough.
  • a membrane 4 parallel to the electrodes 2, 3 is arranged between adjacent electrodes 2, 3.
  • the cell troughs are each made up of four profile plates 6, the electrodes 2, 3 and membranes 4, between the receiving electrolyte space halves 5.
  • the profile plates 6 of the cell troughs are clamped together in a pressure-tight manner in a block frame 7 with two parallel block end plates 8, 9 arranged on the end face (cf. FIGS. 1, 2).
  • the profile plates 6 consist of injection molded parts. In their corner areas, they and also the anodes 2 are provided with electrolyte supply and drain holes 10 perpendicular to the profile plates 6. In addition, the profile plates 6 have integrated membrane support grids 11. To hold the membranes 4, the corresponding profile plates 6 are provided with clamping ribs 12 and associated clamping grooves 13. For pressure tightness, d. H. to seal the electrolyte spaces (anolyte, catholyte space), the profile plates 6 are also provided with grooves 14 for sealing cords or O-rings 15.
  • the profile plates 6 are provided with upper and lower guide recesses 16 for horizontal cross members 17 of the block frame 7.
  • the block end plates 8, 9 are made of steel. They are held together with the aid of tie rods 18. But you can too be clamped together using at least one hydraulic cylinder piston arrangement.
  • the one block end plate namely the block end plate 8 to be seen on the left in FIGS. 1 and 2 or the block end plate 8 shown in FIG. 3, is fixedly arranged in the block frame 7.
  • the other block end plate 9, on the other hand can be moved in parallel, namely after removing the tie rods 18. In this way, additional cells can be added or excess cells can be removed.
  • the fixed block end plate 8 is provided with electrolyte supply and drain connection 19.
