Abstract:
A spiral manifold assembly for a bipolar electrolyzer comprising:a first outer assembly member having inner and outer ring members positioned at least substantially concentric one to the other and providing a central aperture within said inner ring member, a circumferential band member extending between and connecting to said ring members and having a front, at least substantially flat circumferential surface, a back circumferential surface having a recessed circumferential channel therein, a radial barrier member across said channel and a channel aperture adjacent said barrier member that penetrates through said band member;a second outer assembly member spaced apart from said first outer assembly member and having inner and outer ring members positioned at least substantially concentric one to the other and providing a central aperture within said inner ring member, a circumferential band member extending between and connecting to said ring members and having a front, at least substantially flat circumferential surface, a back circumferential surface which has a recessed circumferential channel therein, a radial barrier member across said channel and an inwardly extending channel passageway adjacent said barrier member, which passageway extends from said recessed channel inwardly to said central aperture that is within said inner ring member; anda center assembly member, between said first and second outer assembly members, and comprising inner and outer ring members positioned at least substantially concentric one to the other and providing a central aperture within said inner ring member, a circumferential band member extending between and connecting to said ring members and having front and back circumferential surfaces, with each surface having a recessed circumferential channel therein, with a radial barrier member across each channel, with one recessed channel having an aperture through said band member and adjacent a barrier member, and one recessed channel having adjacent a barrier member, an inwardly extending channel passageway extending from said recessed channel inwardly to said central aperture that is within said inner ring member, said center assembly member being in releasible interengagement with said first and second outer assembly members.
