Apparatus for production of sodium hypochlorite

Electrolyzer apparatus for electrolyzing synthetic and natural brines for producing hypochlorite therefrom comprising

• a. an elongated electrically non-conductive casing having a horizontally disposed longitudinal axis, said casing having unobstructed openings at both ends thereof,
• b. removable cover means secured to each of said casing open ends, each of said cover means having an opening therethrough communicating with interior of casing from exterior thereof,
• c. gasket means interposed between said cover means and casing open ends,
• d. a first fluid flow passageway through a wall of said casing in the proximity of one end thereof and a second fluid flow passageway through a wall of said casing in the proximity of its other end,
• e. a self-standing bipolar electrode assembly of a plurality of at least two cells contained within said casing such that longitudinal axis of said electrode assembly substantially registers with longitudinal axis of said casing, said cell including arrays of interleaved electrode plates consisting of anode plates and cathode plates supported by a framework comprising
• i. at least one electrically non-conductive partition disposed normally to said casing longitudinal axis and spaced intermediate the ends of said electrode assembly, said partitions serving to baffle said cells and provide cell compartments therefor
• ii. a conducting stud provided at each end of said framework to engage said opening provided in each of said cover means to provide a projecting positive binding post and a projecting negative binding post, and
• iii. gasket means interposed between said conducting studs and said cover means.
