Description
Eleetrolyseur ä diaphragmes verticaug. L'invention a pour objet un el:eetrolys-eur ä diaphragmes vertvcaug et anocdes de :char- bon. Vertical diaphragm electrolyser. The subject of the invention is an electrolyser with green diaphragms and carbon anodes.
Daus, lies electrolyseram .de to type, la,du- r6e des. anoides, compte tenu naturellement de la. quantite intrinseque des charbons, est in fluenc6e par lt plus ou moins grand degre :de perfection du paradl6lisme des anocdes et des cathodes. Daus, links electrolyseram .de to type, la, du- r6e des. anoides, given naturally the. intrinsic quantity of the carbons, is influenced by the greater or lesser degree of perfection of the parallelism of the anodes and the cathodes.
En effet, si ce parallelis:me n'est pas par fait, des afflux de courant s'etabliss,ent dans les charbons formant ano:d:es" aua endroits oü ils sont plus rapproche:s des catho:dm. Ces s@ur- charges lo:cale:s accasionnent natureldement leur desagrega@tion et leur usure prematuree. Indeed, if this parallelis: me is not perfect, current influxes are established, ent in the coals forming ano: d: es "at the places where they are closer: s catho: dm. These s @ur- loads lo:cale:s naturally cause their disintegration and premature wear.
L'electrolyseur falsant 1'objet de 1'inven- tion comporte au moins. une anode constitu & par un bloc de forme cylindrique ou prisma tique perfüre d'un trau borgne et enfile sur une tige de suppoirt de diamMre plus faible que celui de la perforation, mais voisin de cedui- ci, cette anode rep,osant pair 1e fand dudit trau borgne sur lachte tige, dont .1e pied reposs.e sur 1e fand de 1'electrolys:eur -oü il,est immobilis:e, 1e tout etant etabli de faqon ä assurer 1e pa- rallelis#me .de lachte anode et d'au moins une cathode. The electrolyzer falsant the object of the invention comprises at least. an anode consisting of a block of cylindrical or prismatic shape perforated with a blind trau and threaded onto a support rod of smaller diameter than that of the perforation, but close to this one, this anode rests, daring even the first fand of said blind trau on the lachte rod, whose .1e foot rested.e on the 1e fand of the electrolyser: eur - where it is immobilized: e, the first everything being established so as to ensure the 1e parallelis#me .de lachte anode and at least one cathode.
Le bloc peutdone etre,cylindrique ou pris- matique, 1e trou borgne etant de p@reference axial:. The block can therefore be cylindrical or prismatic, the blind hole being preferably axial.
Le fond de la perforation de 1'anode peut etre ferme par un crayon de chaxbon, s:odidaire de 1'anode, dopt il constitue 1'amenee :de eou- rant, et traversant 1e plafond de 1'eleetrody- ,seur ä travers un joint Manche, 1'etanchäite de ce joint pouvant etre :abtenue par une sim ple eoulAe de mastic de joint. The bottom of the anode perforation can be closed by a chaxbon pencil, separate from the anode, since it constitutes the current supply, and crossing the ceiling of the electrodyseur at through a Channel joint, the sealing of this joint being able to be: abtenuated by a simple eoulAe of joint mastic.
Le fand .de 1'äleetrolys,tur peut comporrter au moinss une aWole pour re evoir et immo- biliser 1e pied de Iadite tige de suppo:rt. The fand of the aleetrolys, tur may comprise at least one flange to receive and immobilize the foot of said support rod.
Le dessin annege repräsente, ä eitre d'exemple, une forme d'execution de 1'6lec- trolyseur faisant 1'objet de 1'invention. The accompanying drawing shows, by way of example, one form of execution of the electrolyser which is the subject of the invention.
Fig. 1 est une elevation perspective, avec arrachements partiels:, de cette forme d':exe- cution. Fig. 1 is a perspective elevation, with partial cutaways, of this form of execution.
Fig. 2 en est une coupe transversade. L'electrodyseur repr6sente :au,dessin com- porte, à la manière habituelle, un cadre 1, sur les deux faces duquel sont appliqués et maintenus, par un dispositif approprié connu, les éléments de cathode ?. On voit en 3 (fig. 2) les diaphragmes casuels. Dans la se melle inférieure du cadre 1 sont ménagées de; alvéoles 4, équidistantes des deux éléments de cathode ?, 3. Dans c-s alvéoles sont post e:r verticalement des tiges de verre 5. Sur cha cune de ces tiges est enfilée une anode W- menta.ire 7, munie à cet effet d'un trou axâal 8, de diamètre légèrement supérieur à celui de la tige 5. Le fond du trou 8 est fermé par un crayon en charbon 9, situé clans la partie supérieure de .l'anode élémentaire 7. C'est par l'extrémité inférieure de ce crayon 9 que l'anode est ainsi suspendue sur l'extrémité su périeure de la tige 5. Le crayon 9 traverse .le plafond 7 0 de l'éleetrolyseur. Le joint entre le crayon. 9 et le plafond 10 est obtenu en coulant sur le plafond 10, qui est placé un peu en contrebas de la. partie supérieure du cadre 1, un coulis de mastic goudronneux, tel que ceux utilisés habituellement pour réaliser les joints dans les électrolyseurs. Fig. 2 is a transverse section. The electrodyseur represents: in the drawing comprises, in the usual way, a frame 1, on the two faces of which are applied and maintained, by a known suitable device, the cathode elements ?. We see in 3 (fig. 2) the case diaphragms. In the lower sole of the frame 1 are provided; cells 4, equidistant from the two cathode elements?, 3. In c-s cells are post e: r vertically glass rods 5. On each of these rods is threaded an anode W- menta.ire 7, provided for this purpose with an axâal hole 8, of diameter slightly greater than that of the rod 5. The bottom of the hole 8 is closed by a carbon pencil 9, located in the upper part of the elementary anode 7. It is by the lower end of this pencil 9 that the anode is thus suspended on the su périeure end of the rod 5. The pencil 9 crosses .the ceiling 7 0 of the éleetrolyseur. The joint between the pencil. 9 and the ceiling 10 is obtained by casting on the ceiling 10, which is placed a little below the. upper part of the frame 1, a grout of tarry mastic, such as those usually used to make joints in electrolysers.
Par ce qui a été exposé ci-dessus, on se rend compte que la, position des anodes élé- menta-ires, par rapport aux éléments de catho des, est assurée de façon correcte en ce qui concerne le pa.rallélisme entre anode et ca thode, car les anodes élémentaires ne peuvent subir de glissement latéral; elles reposent par leur poids sur un support rigide, en un point qui n'est susceptible ni d'usure ni de dété rioration et qui est situé au-dessus, de leur centra de gravité. Ces anodes élémentaires conserveront toujours: dans l'électrolyseur, tant qu'il restera quelque épaisseur de char bon autour de la baguette 5 ou tige de sup- port, leur position verticale rigide et leur ali gnement parfait dans. .le plan médian des ca thodes. Leurs écartements par rapport .à ces derniers seront donc toujours identiques et réguliers. Il est d'autre part facile, par une rotation des anodes autour de leur axe, de modifier leur -orientation pour présenter en face des cathodes de nouvelles portions d'a nodes élémentaires, lorsque ces anodes ont subi une usure suffisante pour amener une augmentation indésirable de la tension entre anode<B>et</B> cathode. By what has been explained above, we realize that the position of the elementary anodes, relative to the cathode elements, is ensured in a correct manner with regard to the parallelism between anode and ca thode, because the elementary anodes cannot undergo lateral sliding; they rest by their weight on a rigid support, at a point which is not liable to wear or damage and which is situated above their center of gravity. These elementary anodes will always retain: in the electrolyser, as long as there remains some thickness of good coal around the rod 5 or support rod, their rigid vertical position and their perfect alignment within. .the median plane of the ca thodes. Their spacings relative to the latter will therefore always be identical and regular. It is on the other hand easy, by rotating the anodes around their axis, to modify their -orientation to present in front of the cathodes new portions of elementary nodes, when these anodes have undergone sufficient wear to bring an increase voltage between anode<B>and</B> cathode.
Enfin; la perforation axiale de anodes élémentaires permet une imprégnation plus régulière de celles-ci, la pénétration du liquide d'imprégnation (huile de lin par exemple) se faisant à la fois par l'intérieur et par l'exté rieur. De plus, l'air emprisonné dans les pores (les charbons pouvant plus facilement s'échap- pe.r ,lors de l'imprégnation, il est moins à craindre que des parties des charbons ne soient pas imprégnées. Finally; the axial perforation of the elementary anodes allows a more regular impregnation thereof, the penetration of the impregnating liquid (linseed oil for example) taking place both from the inside and from the outside. In addition, the air trapped in the pores (the carbons being able to escape more easily during impregnation, it is less to be feared that parts of the carbons are not impregnated.
L'élee,trolyseur objet de l'invention peut être utilisé pour électrolyser des lessives chlorées. The electrolyser object of the invention can be used to electrolyze chlorinated detergents.
