Title
(EN) ION EXCHANGE MEMBRANE CELL FOR HIGH PRODUCT CAPACITIES
(FR) CELLULE A MEMBRANE ECHANGEUSE D'IONS A FORT DEBIT DE PRODUIT
Abstract
(EN)
The product capacity of an ion exchange membrane cell for the generation of chlorine and alkali caustic solutions is limited by mechanical design facts. A cell according to this invention allows a substantial increase of its product rates by assembling of several individual electrode plates (4A, 4B) in each single cell element, which are placed piece by piece in the halfshells of the cells, aligned, adjusted and fastened by adjustment members (16) piece by piece. Dependent on the capacity the cell elements can be equipped with different numbers of inlet and outlet pipes. With respect on the recoating procedures of the electrode surfaces outside of the cells the fastening means (16) of the electrode plates are removable in such a manner that the plates can be replaced multiple times without mechanical destruction of cell or plate parts.
(FR)
La capacité de production des cellules à membrane échangeuse d'ions servant à produire des solutions caustiques de chlore et d'alcali se trouve limitée par des considérations d'ordre mécanique. Les cellules de l'invention permettent de substantielles améliorations du débit de produits du fait du groupement dans une même cellule de plusieurs plaques électrodes placées pièce par pièce dans les demi coquilles des cellules, puis alignées, réglées et fixées pièce par pièce. En fonction de leur capacité les cellules sont dotées d'un nombre plus ou moins grand de conduits d'entrée et de sortie. Pour d'effectuer les procédures de réenrobage des surfaces des électrodes hors des cellules, les moyens de fixation des plaques d'électrodes sont amovibles de manière à pouvoir remplacer les plaques de nombreuses fois sans avoir à détruire mécaniquement certaines parties de cellules ou de plaques.
