Abstract

It is described an amalgam decomposer for mercury cathode electrolytic cells, provided with a liquid distributor (8) consisting of an arrangement of conduits comprising an external annulus (15), one or more internal annuli (16) and a central distributing tube (17) suitable for being crossed in sequence by a water flow. The distributor of the invention is suited to the upward feed of a graphite pack (7) crossed by the amalgam under gravity comprising at least one gas diffuser of anyone of the preceding claims. Arrangements of graphite packs disposed as a bundle of tubes, each fed by a distributor of the invention are also provided.
