ELECTROLYTIC OZONE-GENERATING APPARATUS AND THE PROCESS FOR MANUFACTURING THE SAME

摘要

The present invention relates to an electrolytic ozone-generating apparatus and the process for manufacturing the same. The apparatus comprises an ozonizer, an anode water box, a cathode water box, an equilibrium device, and circulating tubes between water boxes and the ozonizer, and is characterized in that said ozonizer comprises (a) a cation-exchange membrane, (b) an anodic catalyst sheet (comprising mainly of PbO2), (c) a cathodic catalyst sheet (comprising mainly of Pt-C powder), (d) a porous anode current-collecting plaque, and (e) a cathode current-collecting plaque. Whereby said anodic and cathodic catalyst sheets contact closely with the corresponding side of the membrane, and said anode and cathode current-collecting plaques are in contact with the corresponding side of the anodic and cathodic catalyst sheets. This apparatus can be produced in mass-scale with low cost, and operated stable with high ozone generation efficiency under pressure.
