1. Ozonising apparatus for the production of ozone from a gas being at least partially composed of oxygen, by means of glow discharges generated by a pulsed high voltage current, the apparatus comprising (a) a tube for the circulation of the gas to be ozonised, made from an electrically insulating material resistant against ozone and glow discharges, forming a cylindrical winding ; (b) as a first electrode, a conducting wire disposed in the interior of said tube ; and (c) a second large area electrode, characterized by the fact that the said tube is made of glass, quartz or ceramics, that it is wound on a metallic cylindrical mandrel, that the winding formed by the tube is covered by a metallic sheet or grid as a substantially cylindrical layer on the exterior surface of the spires forming the tube winding, said metallic layer being in turn covered by a layer of insulating material, that the mandrel and said metallic sheet or grid forming the second electrode are both earthed, and that the conducting wire is connected to a voltage feeder electrode disposed within a block of insulating material bearing borings allowing the passage of the gas to be ozonised. |
