Definitions
- the present invention relates to the construction of an electrolyser of the filter press type, and more particularly to an electrolyser intended to operate under high pressure and at high temperature, for example an electrolyser which is the subject of French patent No 2448583.
- an electrolyser of the filter press type consists of a stack of several hundred elementary electrolysis cells, this stack appearing as an alternating succession of electrodes and diaphragms delimiting spaces in which circulates the 'electrolyte. Also conventionally, and in order to obtain maximum power, this stack is placed in a sealed enclosure filled with an inert gas and brought into operation at high pressure and temperature.
- the temperature inside the pressurized enclosure can vary considerably, being for example of the order of 160 ° C during operating hours and 20 ° C during operating hours. Eve.
- the stacking of cells being mounted at room temperature, it is necessary, to ensure the proper functioning of the electrolyser at its operating temperature, that the geometric shapes of the initial stacking are kept at working temperature in despite the expansions due to the rise in temperature.
- the electrodes are made of a metallic material, generally nickel, with a low coefficient of expansion.
- the diaphragms are formed either by an asbestos cloth or by a nickel or Tefton reps ", materials with a low coefficient of expansion, and are often crimped in a rigid frame made of nickel or other material which also expands very little.
- a material resistant to corrosion such as a fluoropolymer, possibly loaded with nickel or asbestos, for example polytetrafluorethylene, known as PTFE.
- This type of material if it has excellent qualities of creation of sealing, electrical insulation, and resistance to corrosion , unfortunately has the disadvantage of expanding five to ten times more than the other constituent materials of the stack, so that it is found that, in the case of use of non-crimped diaphragms in a nickel frame, many tears occur in the diaphragms, and in addition in all cases the stack does not keep its initial geometric shape so that the performance of the electrolyser is deeply affected.
- the electrolyser of the filter press type of which it is the object is characterized in that it is equipped with bracing frames each consisting of at least two frame portions, each of these portions comprising a fixed point and being assembled to the adjacent portion or to the two adjacent portions by sliding junctions.
- the electrolyser of the invention is equipped with diaphragms 1 in nickel reps, each crimped in a rigid frame 2, also in nickel.
- Each frame 2 is engaged with the possibility of sliding in a corresponding groove made in the spacer frame 4 made of PTFE which, in a very conventional manner, serves both as a joint and as a support for the electrodes 5 and the diaphragm 1.
- each bracing frame 4 consists of four portions (41,42,43,44) which are mounted end to end so as to form said frame, using sliding assemblies of which FIG. 2 shows in more detail and by way of example that surrounded by dashed lines at the bottom left of FIG. 1. Furthermore, each frame portion is provided in its central part with a fixed point, respectively 61, 62, 63, 64, having the role of preventing at this location any deformation by expansion of the frames 4 relative to the electrodes 5.
- a fixed point 62 is constituted by a set of nickel washers 7 force-fitted into a channel 8 previously pierced longitudinally in the cell stack.
- the fixed points 61 and 63 are located respectively between the evacuation channels 91 and 92 and the supply channels 101 and 102, and the fixed points 62 and 63 are located respectively at the other two angles of the square formed by a frame 4.
- FIG. 2 shows that it is possible to make the electrolyser of the invention by providing, with formally to the teaching of the aforementioned French patent No 2448583, the frames 4 thereof of distributing grooves 212 and collecting collectors 211, using the terms and references of said patent, the distributing grooves 212 being supplied with demineralized water as explained in detail in said French patent.
- the rigid frames 2 are fitted into the grooves 3 so as to leave, at room temperature, a sufficient sliding space 31.
- the fixed points such as 62 can be produced in a manner other than that described with reference to FIG. 3. They can for example be simply constituted each by a screw and nut assembly or be made, as shown in FIG. 4, simply by riveting using the electrodes themselves, then slightly folded along the orifice 8 so as to firmly hold the frames 4.
- FIGS. 1 to 4 rather relates to an electrolyser equipped with small cells, 50 cm side for example.
- the side of which may for example be of the order of 150 cm, it will be preferable to match the stack of frames each consisting of more than four sliding portions, one in the other, each of these portions also being equipped with a fixed point preferably located in its median plane.
- Fig. 5 shows an embodiment of such an electrolyser of larger dimensions.
- each frame 4 is constituted by eight sliding portions 411 to 418, each of these portions being provided in its median plane with a fixed point, respectively 611 to 618.
- each of these could be made up of a number of sliding portions with fixed point according to the invention which may be equal to 12 or more.
