ABSTRACT:
Electrolytic production of ozone by a process wherein an oxygen-saturated mixture of water and oxygen, or air, is led along both sides of a solid electrolyte (1), which acts as an ion-exchange membrane and carries coatings (2,3) of electrically conductive materials, both on the cathode side and on the anode side, ozone being evolved, in addition to oxygen, on the anode side and, on the cathode side, the evolution of hydrogen being suppressed by the depolarizing effect of the oxygen which is entrained in the water stream, and merely water being formed. The electrolysis is carried out under an increased pressure.
Individual electrolysis cell bounded by bipolar plates (6), and comprising a solid electrolyte (1), provided, in each case, with a surface coating (2,3), and centrally located between current-collectors (4) and adjoining open metallic structures (5). A plurality of individual cells integrated together between end plates (7), electrically connected in series and hydrodynamically connected in parallel, combined to form a block.
Use in water-treatment, and as a component of chemical processes (oxidation processes).
