Definitions

  • the present invention relates to an electrolyser of the filter press type equipped with bipolar electrodes provided with "pre-electrodes" in the form of grids or perforated plates which are applied against the opposite faces of each diaphragm.
  • electrolysers with electrodes provided with "preelectrodes” are familiar to a person skilled in the art, and are for example described in French patents 2,338,060, 2,416,274 and 2,448,582.
  • the present invention relates to an electrolyser of this type, in which the electrodes are constituted by solid metal plates, while the pre-electrodes are constituted by mesh or perforated plates parallel to the electrode plates and separated from the latter by tabs. of bracing, said electrolyser being of design significantly improved compared to known electrolysers, such as that according to French patent 2,448,582 of the applicant, both from the point of view of ease of manufacture and from the point of view of precautions against corrosion.
  • each spacer strip has an S shape and is welded on the one hand to the associated pre-electrode on a solid strip thereof and on the other hand to the associated electrode plate so as to leave a slight offset with the tongue located almost continuously on the opposite face of said electrode plate, and in that the bracing tongues are staggered, seen in a plane parallel to the electrodes.
  • the electrolyser comprises a stack of insulating frames 10, usually called "spacer joints", which are partially shown. From the electrolysis cells are housed inside this stack of insulating frames 10. These cells, partially shown, are identified for example 1 or l 'in FIG. 1.
  • Each cell is delimited between two 2-plane electrode plates.
  • Each electrode plate 2 is metallic and has a small thickness. It is bathed on its two opposite faces 21 and 22 by the electrolyte.
  • Each electrode plate 2 is bipolar. One of its faces, 21 for example, is an anode on which oxygen is formed, the opposite face 22 then being a cathode on which hydrogen is formed. It is for example made of nickel.
  • Each cell is divided into two compartments 31 and 32 by a diaphragm 4. The compartment 31 located on the side of the face 21 contains the anolyte, the compartment 32 located on the side of the face 22 containing the catholyte.
  • Each diaphragm 4 is stretched in the bore of a bracing frame 10. It is for example produced using an asbestos fabric.
  • Each cell also comprises two electrode plates 5 and 6, usually called “pre-electrodes", which are arranged on either side of the diaphragm 4 of this cell so as to be pressed against this diaphragm and at a certain distance from the two electrode plates 2 limiting this cell.
  • Each pre-electrode plate 5 or 6 is constituted by a sheet of expanded metal discontinuously, so that the pre-electrode obtained is presented as a sheet of expanded metal provided at regular intervals with solid metal strips (61,62 , 63) of small width and parallel to the horizontal plane.
  • Each electrode plate 2 is housed between a plate 5 called the pre-electrode of a cell and a plate 6 called the pre-electrode of the neighboring cell.
  • Each diaphragm 4 is sandwiched between the two pre-electrodes 5 and 6 which contribute to its maintenance.
  • the pre-electrode plates are connected to the electrode plates by spacer tabs 7 all identical, but having, in accordance with the present invention, an S shape as is see in Figure 1, which avoids the creation of sharp angles favorable to corrosion.
  • the bracing tongues 7 are, seen in a plane parallel to the two electrodes, arranged in staggered rows. They are welded at one of their ends to the pre-electrodes 2 on the metal strips such as 61, and at their other end to the corresponding pre-electrode 2. As can be clearly seen in FIG.
  • This construction method has the enormous advantage of allowing online transparency welding both on the solid strips such as 61 of the pre-electrodes and on the electrode plates, the online transparency welding being carried out for example by beam. of electrons in a direction parallel to the bands (61,62,63), as indicated by the arrow F in Figure 2.
  • the pre-electrode plate 6 is here made up of a set of tiles ( 601, 602, etc.) at least one side of which is parallel to the welding direction F, the counter tiles having a square shape, and the side tiles being optionally cut so as to produce the outer shape of the pre-electrode 6.
  • the solid electrode 2 is constituted by a set of bands (201,202,204,205,206,207,208) of substantially equal width, except for the extreme bands (201,208), at the height of the tiles (601,602, etc ...), and which are joined by welding along the weld line F by transparency of the bracing tongues, that is to say parallel to the strips (61, 62, 63, etc.).
