FILTER-PRESS ELECTROLYZER Russian patent published in 1994 - IPC

FIELD: preparing oxygen and hydrogen through electrolyzing aqueous alkaline solutions, securing operating environments, feeding gas-flame burners. SUBSTANCE: unit has perforated diaphragms made of dielectric and having cone projections and holes with shoulders located in the openings of bipolar electrodes. The diaphragms are fixed by means of a cone shoulder and end edge of cylindrical dielectric bushings having radial openings located on them. The bushings are sufficiently numerous to form discontinuous channels for oxygen and hydrogen to be discharged through. Flexible packings are interposed between the above-mentioned electrodes and diaphragms and rest on the inner perimeter of frames which thickness is 10-20% percent less than that of the bushings. EFFECT: sealed and rigid construction thanks to the bushings coinciding well with the frames in size. 13 cl, 1 dwg
