Abstract
Abstract Apparatus for producing ozone, wherein air or oxygen is passed through two high voltage electrodes mounted opposite each other in a housing and is converted into ozone by electrical discharge. The housing is constructed as a slender tube open at both ends and made from an electrically non-conductive material, while between the two electrodes, extending more or less over the entire inner length of the tube is mounted at least one bipolar electrode without an electrical input or output, which divides the inside of the tube into discharge channels. The bipolar electrode is formed by a surface, on which discharge points are mounted and directed at the earthed electrode. The discharge electrode, directed at the surface of the bipolar electrode, is similarly provided with a plurality of discharge points.
