OZONISERS

摘要

An ozoniser comprises a plurality of parallel electrode assemblies each consisting of concentric metal and dielectric tubes with a gap between them through which air or other oxygen containing gas is passed, the metal tube forming one electrode and a conductive liquid being provided on the surface of the dielectric remote from said gap to form the other electrode. The metal tube is cooled by a liquid flowing therethrough and the liquid of the liquid electrode is used to cool the dielectric tube. One of the electrodes may be earthed; the liquid or coolant for the other electrode is passed through long tubes of electrical insulating material to reduce the current through the liquid if the liquid is conductive.
