Definitions

  • the invention relates to an electrode and a method for gas-generating electro-chemical processes, which in the installed state of a
  • Ion exchange membrane is arranged parallel opposite one another, consisting of a plurality of horizontal lamellar elements which consist of a flat c-section of a flat belly part and one or more flank parts, and between the flat belly part and the one or more other flank parts one or more arbitrarily shaped transition areas are arranged, wherein the
  • Lamella elements have a plurality of through openings.
  • Electrolysis apparatus can be used. These electrodes are known inter alia from DE 198 16 334 A1 of the applicant. Herein, an electrolyzer for producing halogen gases from aqueous alkali halide solutions will be described. Since the flow conditions in the production of gas in the electrolyte are adversely affected by the resulting product gas in the membrane electrode area, it is proposed in DE 198 16 334 A1 to incorporate the louvered single ribs of the electrode inclined to the horizontal. This causes a laterally directed flow in the cell, since the gas bubbles located under the individual lamella follow the constructive opening upwards.
  • DE 44 15 146 A1 proposes to provide holes or bores in the downwardly directed fin part and thus the
  • CONFIRMATION COPY still remains in the vicinity of the contact point and the obstructed there flow of the electrolyte.
  • Lamellar elements which in turn are structured and shaped in three dimensions and with a partial surface in direct contact with the membrane, wherein the
  • Slats elements have grooves and holes, and wherein the plurality of holes are arranged in grooves, and wherein the hole surfaces are wholly or partially in the grooves or protrude into this.
  • the disadvantage is that the groove arrangement, a surface is formed which has constructive elevations and depressions, which leads to a disadvantageous gas stagnation and thereby due to an uneven
  • the problem is solved by the use of the electrode of an electrolytic cell for gas-generating electro-chemical processes.
  • the electrode comprises a plurality of horizontal lamellar elements, which in the nature of a flat C-profile consist of a flat belly part and one or more flank parts, and between the flat belly part and the one or more
  • Flank parts are arranged one or more arbitrarily shaped transition regions, wherein the lamellar elements have a plurality of through openings and a flat surface without constructive elevations and depressions, and wherein the flat waist portion has a plurality of in-line through holes arranged diagonally to each other.
  • the present invention differs from a continuous one
  • Perforated plate as proposed, for example, in DE 69600860 T2, in DE 243256 A1, and DE 2630883 A1, in that the electrode is composed of a multiplicity of lamellar elements which are shaped in three dimensions by deliberate stretching by cold deformation. This bend will make the
  • the area of the abdominal part is optimally utilized to accommodate the largest possible number of openings and thus to further reduce gas stagnation.
  • the flank parts are provided with through openings.
  • ion exchange membrane arranged when the electrode is installed in an electrolytic cell. This arrangement serves the purpose of supplying the ion exchange membrane with electrolyte during operation of the electrolytic cell, as well as ensuring gas discharge.
  • the through openings are formed as punched holes.
  • these openings may have any geometric shape, with openings with a round cross section are preferred.
  • the lamellar elements at round through openings to a plate thickness which is smaller than the hole diameter or have the lamellar elements in non-round through openings to a plate thickness which is smaller than the hydraulic cross section.
  • Electrode is the one or more other flank parts in the installed state in an electrolytic cell at an angle of at least 10 degrees angle away from the membrane, the transition areas are advantageously formed as a rounded edge.
  • the distance between the individual horizontally arranged Lammellen shame in C-profile with each other 0 to 5 mm, preferably 0 to 2 mm and more preferably 0 mm.
  • the process is optimized, since about 6 to 10% of the membrane surface are recovered and are available for the actual electrolysis process.
  • the electrolysis process which is the subject of the present invention is characterized by the use of a planar electrode as described above.
  • Fig. 1 A plan view of a fin element according to the invention in
  • Fig. 1 shows a lamellar element 1 in the embodiment of a flat C-profile.
  • the folded back flanks 2 and 3 are kept very short in relation to the flat belly part 8, which is designed to be many times wider. Between the flanks 2 and 3 and the belly part 8 are the transition areas 4a and 4b.
  • the lamellar element 1 has in the flat abdominal region 8 arranged in rows holes 5, wherein these rows of holes are arranged parallel to each other and the
  • Openings are arranged from one row of holes to the next diagonally to each other.
  • the available area of the abdominal part 8 can be used most effectively for the electrolysis.
  • a significant advantage of this embodiment is that the belly part 8 is arranged in the installed state plane-parallel to the membrane 7, in which the electrochemical reaction can proceed.
  • the membrane 7 is supplied via the holes 5 with brine or brine.
  • the cell voltage of an electrolytic cell was determined using an electrode which was constructed from a C-profile-like configuration of the lamellar elements of the present invention.
  • the cell voltage of an electrolytic cell was determined using an electrode which was constructed from a C-profile-like configuration of the lamellar elements of the present invention.
  • Cell voltage of an electrolytic cell using an electrode which consists of a C-profile-like embodiment of the invention disclosed in DE 102005006555 A1 invention, which differs in that the holes provided are arranged in grooves and the surface of the lamellar elements thus constructive elevations and
  • the experiment used C-profiles had 11 x 62 holes, which in the case of inventive design were arranged in rows of holes which are arranged diagonally to each other.
  • the hole diameter was 1, 5 mm and the height of the C-profile was 23 mm.
