Alkali metal hypochlorite generation-storage unit

An alkali metal hypochlorite generation-storage unit comprising at least one tank [1] provided with an electrolyte level mark [2], a bottom [7], one or more drain valves [6], an opening for inlet of the electrolyte feed materials, supports [8], and at least one pair of electrodes, namely at least one cathode [10] optionally provided with an electrocatalytic coating for the evolution of hydrogen gas separated from at least one anode [11] provided with an electrocatalytic coating for chlorine generation, said electrodes being electrically connected to an external direct current power source by suitable connections [9], and a means for promoting circulation of electrolyte by hydrogen gas-lift consisting in at least one assembly positioned inside or outside said tank and comprising a support plate [15], gasket [14], a lower portion [3] of a gas-lift tubular body provided with openings [4] for the in-flow of substantially gas-free electrolyte, an upper portion [5] of the gas-lift tubular body having an open top for the discharge of the hydrogen gas/electrolyte dispersion, and a zone for separating electrolyte from the hydrogen gas. In addition said electrolyzer may comprise a perforated hydrogen/electrolyte drip plate above said tubular body.
