OZONE GENERATION APPARATUS

PROBLEM TO BE SOLVED: To provide an ozone generation apparatus with a high generation efficiency.SOLUTION: An ozone generation apparatus comprises a container, a first metal electrode 13, a dielectric electrode 14, a heat pipe 15, a heat sink 16, and an electric power source C. The first metal electrode is a cylindrical electrode with its axial direction being a first direction d1 and has its outer peripheral surface supplied with a cooling medium. The dielectric electrode is a cylindrical electrode that faces an inner peripheral surface of the first metal electrode and that is coaxial with the first metal electrode. The heat pipe faces an inner peripheral surface of the dielectric electrode and has conductivity. The heat sink is disposed outside of a space outward of a space between the first metal electrode and the heat pipe, and is connected to the heat pipe. The electric power source applies voltage to the heat pipe, and at least one electric discharge gap I1 between the first metal electrode and the dielectric electrode and between the dielectric electrode and the heat pipe, electric discharge is caused to generate ozone. The ozone generation apparatus, as the heat sink can be cooled with a raw material gas D1, can increase cooling efficiency of the electric discharge gap.SELECTED DRAWING: Figure 2 【課題】高い発生効率のオゾン発生装置の提供。【解決手段】容器と第１金属電極１３と、誘電体電極１４とヒートパイプ１５と、ヒートシンク１６と電源部Ｃを備える。第１金属電極は、第１方向ｄ１を軸方向の円筒状の電極で、外周面に冷却媒体が供給される。誘電体電極は、第１金属電極の内周面に対向し設けられかつ第１金属電極と同軸の円筒状の電極。ヒートパイプは、誘電体電極の内周面に対向し設けられかつ導電性を有する。ヒートシンクは、第１金属電極とヒートパイプの間の空間の外方の空間の外部に設けられかつヒートパイプに接続され、電源部は、ヒートパイプに電圧を印加し、第１金属電極と誘電体電極との間、及び誘電体電極とヒートパイプの間の少なくとも一方の放電ギャップＩ１で放電させてオゾンを発生させる。原料ガスＤ１によりヒートシンクを冷却できるので放電ギャップの冷却効率を高めることができるオゾン発生装置。【選択図】図２
