Abstract

1396019 Electrolyzers ENGELHARD MINERALS & CHEMICALS CORP 7 Sept 1972 [8 Sept 1971 20 March 1972] 41666/72 Heading C7B An electrolytic cell for continuous electrolysis of sodium chloride to form sodium hypochlorite, e.g. for addition to water supplies, comprises a cylindrical bi-polar electrode 24 and coaxial cylindrical electrodes 22 and 23 to form a continuous annular passage between the bi-polar electrode and the mono polar electrodes. As shown the electrodes are supported by insulating members 4, 5, 6 (and 30) and 7 (and 31) which also provide electrolyte inlets 39, 40 and outlets 41, 42. Alternatively the cell may be arranged with the bi-polar electrode exterior to the anode and cathode. The electrodes may be of Ti; the anode and anodic part of the bi-polar electrode being coated with a platinum metal, e.g. Pt, Rh or Ir or with ruthenium oxide. A plurality of cells may be connected in series by bolts 18-21. The two halves of the series may be electrically connected in parallel so that electrolyte enters and leaves the series at zero potential, with the mid-point of the series being at the highest potential Fig. 3 (not shown).
