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 to an electrolyser which is the subject of French Patent No. 2,448 .583.
an electrolyser of the filter-press type consists of a stack of several hundred elementary electrolysis cells, this stack being presented 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, nickel in general, with a low coefficient of expansion.
the ' diaphragms are made up either of an asbestos cloth or a reps of nickel or of "TEFLON" materials with low coefficient of expansion, and are often set in a rigid frame in nickel or other material which also expands very little.
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 slidingly.
the electromagnetizer of the invention is equipped with diaphragms 1 in nickel reps, each set in a rigid frame 2, also in nickel.
Each frame 2 is engaged with the possibility of sliding in a corresponding groove dante 3 made in the spacer frame 4 made of PTFE which, in a very conventional manner, serves both as a seal 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 2 of which is shown 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 middle 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 discharge 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 produce the electrolyser of the invention by providing, in accordance with the teaching of the aforementioned French patent 2,448,583, the frames 4 thereof "distributing" 212 and “collecting” 211 grooves, using the terms and references of said patent, the "distributing" 212 grooves 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 sufficient sliding space 31 at room temperature.
the fixed points such as 62 can be produced in other ways than by that described with reference to FIG. 3. They can, for example, simply consist each of a screw and nut assembly or be produced, as shown in the figure 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 cells of small dimensions, of fifty centimeters on side for example.
the side of which may for example be of the order of one hundred and fifty centimeters, it will be preferable to match the stack of frames each made up 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 represents an exemplary 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.
