Abstract:
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.
Abstract:
To improve the durability of an ozonizer discharge cell, secure a high material-gas pressure, downsize a discharge cell, and improve the ozone producing efficiency. A discharge cell is constituted with a block 10 obtained by integrally superimposing a plurality of ceramic layers and/or glass layers 11, 12, ... on each other in the layer thickness direction. A discharge void 20 is formed between the ceramic layers and/or glass layers 12 and 14 at both the sides of the ceramic or glass layer 13 as a spacer by using the intermediate ceramic or glass layer 13 as a spacer. Planar electrodes 30 and 30 arranged at the anti-void side of the ceramic layers and/or glass layers 12 and 14 are sealed between two adjacent ceramic layers and/or glass layers 11 and 12 and between two adjacent ceramic layers and/or glass layers 14 and 15.
Abstract:
An ozone generating apparatus has a plurality of ozone generating units connected in series to form a plurality of stages along the path of a gas. Each ozone generating unit has an ozonizing chamber (3) having a material gas inlet (1) and a product gas outlet and ozonizer discharge electrodes (4) disposed in the ozonizing chamber and connected to an AC high-voltage source (7a,7b,7c). The voltage applied to said ozonizing discharge electrodes (4) of the successive stages is so varied that the ozonizing discharge electrodes of downstream stage as viewed in the direction of flow of the gas is supplied with a lower voltage than the voltage supplied to said ozonizer discharge electrodes (4) of upstream stage. A series connection of a plurality of ozone generating units may form a composite ozone generating unit, and a plurality of such composite units may be connected in series to form a plurality of stages. The voltages applied to such successive stages is varied in the same manner a above. The ozone generating unit and the AC high-voltage source (7a,7b,7c) can have module constructions.
