ELECTROLYTIC CELL WITH POROUS TUBULAR CATHODES AND MEMBRANE BAGS SURROUNDING ANODES

摘要

An electrolytic cell for the ion exchange membrane method which comprises: (a) an electrolytic cell main body; (b) a plurality of porous and tubular cathodes disposed in the interior of the electrolytic cell main body; (c) an electrolytic cell bottom plate having therein a plurality of apertures; (d) a plurality of electrically conductive bars each provided with a flange at a lower portion thereof, which are each inserted through the aperture of the electrolytic cell bottom plate into the interior of the electrolytic cell main body and secured to the electrolytic cell bottom plate by the flange; (e) a plurality of porous anodes which are each connected to one of the electrically conductive bars and placed vertically in a face-to-face relationship to the cathodes, and which are disposed alone or in combination with each other between the cathodes; (f) a plurality of bag-shaped molds which have at least the portions facing the anodes and the cathodes being formed by a cation exchange membrane, which are each provided at the bottom thereof with an aperture through which one of the electrically conductive bars can be passed, and are open at the top; (g) a partition plate which is provided on the top of the electrolytic cell main body, and which has a plurality of openings at the positions corresponding to the top openings of the bag-shaped molds; and (h) a plurality of lid members each of which covers an opening of one of the bag-shaped molds.
