Description

La présente invention concerne un électrolyseur constitué par un empilage de cellules entouré d'une enceinte tubulaire horizontale.The present invention relates to an electrolyser constituted by a stack of cells surrounded by a horizontal tubular enclosure.

Les électrolyseurs, tels que ceux destinés à la production industrielle d'hydrogène et d'oxygène par électrolyse de l'eau, sont constitués par un empilage d'un très grand nombre-de cellules élémentaires, ledit empilage étant placé dans une enceinte tubulaire, généralement pressurisée et cylindrique.Electrolysers, such as those intended for the industrial production of hydrogen and oxygen by electrolysis of water, consist of a stack of a very large number of elementary cells, said stack being placed in a tubular enclosure, generally pressurized and cylindrical.

Une telle enceinte doit pouvoir être rapidement et aisément démontée, afin de permettre l'entretien des cellules avec le minimum de perte de temps.Such an enclosure must be able to be quickly and easily dismantled, in order to allow the maintenance of the cells with the minimum loss of time.

La présente invention se rapporte à un électrolyseur à enceinte tubulaire horizontale à démontage rapide. Il est caractérisé en ce que ladite enceinte tubulaire est constituée par un socle fixe vertical et par un corps tubulaire horizontal mobile longitudinalement et monté sur un disposif de roulement.The present invention relates to an electrolyser with a quick-disassembly horizontal tubular enclosure. It is characterized in that said tubular enclosure is constituted by a vertical fixed base and by a horizontal tubular body movable longitudinally and mounted on a rolling device.

La présente invention concerne également un procédé de démontage d'un électrolyseur de ce type caractérisé en ce qu'il consiste à enlever ledit corps tubulaire par translation horizontale et à placer au fur et à mesure dudit enlèvement, des cales de soutien sous le corps de la pile de cellules d'électrolyse laisse à nu par ledit enlèvement.The present invention also relates to a method for dismantling an electrolyser of this type, characterized in that it consists in removing said tubular body by horizontal translation and in placing, as and when said removal, support wedges under the body of the stack of electrolysis cells left bare by said removal.

L'invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation, en référence aux dessins annexés dans lesquels :

  • - la figure 1 représente schématiquement un électrolyseur conforme à l'invention, son enceinte tubulaire étant en position de fermeture ;
  • - la figure 2 représente schématiquement l'électrolyseur de la figure 1, avec son enceinte tubulaire en cours d'ouverture ;
  • - la figure 3 est une coupe schématique axiale de l'électrolyseur de l'invention, suivant la ligne AA' de la figure 1.
The invention will be better understood using the following description of an exemplary embodiment, with reference to the accompanying drawings in which:
  • - Figure 1 schematically shows an electrolyser according to the invention, its tubular enclosure being in the closed position;
  • - Figure 2 schematically shows the electrolyser of Figure 1, with its tubular enclosure being opened;
  • - Figure 3 is a schematic axial section of the electrolyser of the invention, along the line AA 'of Figure 1.

En se reportant à l'ensemble des figures 1 et 3, l'électrolyseur de l'invention est constitué d'un empilage horizontal 4 d'un très grand nombre de cellules élémentaires d'électrolyse, cet empilage étant maintenu en place sur le socle de base 2 à l'aide de la plaque de maintien 14 et de huit tirants 3.Referring to all of FIGS. 1 and 3, the electrolyser of the invention consists of a horizontal stack 4 of a very large number of elementary electrolysis cells, this stack being held in place on the base. base 2 using the retaining plate 14 and eight tie rods 3.

La plaque de base 2 de l'électrolyseur est verticale et est fixée à demeure à un socle horizontal 8 constituant le chassis de l'appareil. Par ailleurs, l'empilage 4 est entouré d'un corps cylindrique 1 horizontal et amovible venant, en position de fermeture telle que représentée sur la figure 1, s'accoler contre la plaque de base 2, l'ensemble (1,2) constituant l'enceinte de l'électrolyseur. L'empilage 4 repose sur deux rampes de roulement 5, elles-mêmes reposant sur la partie inférieure de l'enveloppe 1 par l'intermédiaire de galets de roulement 6 et de galets de guidage latéraux 11. Par ailleurs, l'enveloppe cylindrique 1 repose elle-même, par des pieds 15, sur le socle horizontal 8 par l'intermédiaire de galets porteurs 7 portés par les pieds 15, et de galets de guidage latéraux 13 également portés par les pieds 15.The base plate 2 of the electrolyser is vertical and is permanently fixed to a horizontal base 8 constituting the chassis of the device. Furthermore, the stack 4 is surrounded by a horizontal and removable cylindrical body 1 coming in the closed position as shown in the Figure 1, attach against the base plate 2, the assembly ( 1 , 2 ) constituting the enclosure of the electrolyser. The stack 4 rests on two rolling ramps 5, themselves resting on the lower part of the casing 1 by means of rolling rollers 6 and lateral guide rollers 11. Furthermore, the cylindrical casing 1 itself rests, by feet 15, on the horizontal base 8 by means of support rollers 7 carried by the feet 15, and lateral guide rollers 13 also carried by the feet 15.

Comme on le voit sur la figure 1, l'enceinte est attachée, par une fixation 16 à un cable horizontal placé dans le creux du socle 8, et s'entourant autour d'une poulie motrice 10 et d'une poulie de renvoi 17, de manière à pouvoir exercer sur l'enceinte 1 une traction horizontale vers la droite ou vers la gauche permettant respectivement l'ouverture et la fermeture de l'enceinte de l'électrolyseur, comme il sera montrÉ en référence à la figure 2.As can be seen in FIG. 1, the enclosure is attached, by a fastening 16 to a horizontal cable placed in the hollow of the base 8, and surrounding itself around a drive pulley 10 and a return pulley 17 , so as to be able to exert on the enclosure 1 a horizontal traction towards the right or towards the left allowing respectively the opening and the closing of the enclosure of the electrolyser, as it will be shown with reference to FIG. 2.

La figure 2 montre l'opération d'ouverture de l'enceinte par dégagement latéral de l'enveloppe tubulaire 1.FIG. 2 shows the operation of opening the enclosure by lateral release of the tubular envelope 1.

Pour cette opération, on entraîne la poulie motrice 10 dans le sens des aiguilles d'une montre, ce qui tire la partie tubulaire 1 vers la droite. L'enveloppe 1 se déplace alors en roulant par l'intermédiaire des galets 7 sur le socle 8, la partie de l'empilage 4 restant à l'intérieur de l'enceinte 1 étant soutenue à l'aide des galets de roulement 6. Par ailleurs, conformément à l'invention, on place, au fur et à mesure de l'ouverture de l'enceinte de l'électrolyseur, des cales de soutien 12 sous la partie apparente de l'empilage 4 comme figuré sur le dessin.For this operation, the driving pulley 10 is driven in a clockwise direction, which pulls the tubular part 1 to the right. The envelope 1 then moves while rolling by means of the rollers 7 on the base 8, the part of the stack 4 remaining inside the enclosure 1 being supported by means of the rolling rollers 6. Furthermore, in accordance with the invention, place, as and when the enclosure of the electrolyser is opened, support wedges 12 under the visible part of the stack 4 as shown in the drawing.

Le positionnement des cales 12 au fur et à mesure de l'ouverture de l'enceinte peut être soit manuel soit automatique : par exemple, les cales 12 peuvent être des cales parallèlépipédiques couchées lorsque l'enveloppe 1 les recouvre sur le socle 8, et se relevant, par un dispositif classique de déclenchement à ressort, lorsque ladite enveloppe cylindrique 1 ne les recouvre plus.The positioning of the wedges 12 as the enclosure is opened can be either manual or automatic: for example, the wedges 12 can be parallelepipedal wedges lying when the envelope 1 covers them on the base 8, and rising, by a conventional spring release device, when said cylindrical envelope 1 no longer covers them.

L'invention trouve son utilisation pour la production d'hydrogène et d'oxygène à l'aide d'électrolyseur industriel.The invention finds its use for the production of hydrogen and oxygen using an industrial electrolyser.
