OZONE GENERATOR

摘要

An ozone generator for generating ozone by supplying oxygen gas to discharge taking place between two electrodes arranged on the opposite sides of a dielectric sheet across a constant gap, wherein the ozone generation efficiency is enhanced by making narrower the gap. Since the efficiency is lowered due to heating of the electrode, a cooling path (23) is provided in an electrode in order to cool the electrode with water, or the like, but an extremely narrow gap can not be realized because the electrode is deformed by water pressure or heat or the dielectric sheet (4) is warped or cracked. A first recess (600) is made in the surface of an electrode in order to receive a spacer (601) and gap adjusting sheets (603), and the gap is adjusted by selecting the number of the gap adjusting sheets.
