Ozone generating apparatus

Abstract

An ozone generating apparatus according to one embodiment includes a hollow cylindrical sealed container provided with an inlet for a feed gas containing oxygen gas and an outlet for an ozonized gas. A discharge tube including a dielectric tube arranged within the container and a first electrode arranged within the dielectric tube is provided in the container. A second electrode is arranged within the container and surrounds the first electrode, spaced apart from the dielectric tube to form a discharge gap between the second electrode and the dielectric tube. The apparatus further includes a discharge voltage source configured to apply a discharging voltage across the first and second electrodes, and a cooling water jacket surrounding the second electrode. The dielectric tube has an outer diameter of 12 mm or more, but 19 mm or less.

Description

[0001] Cross-reference to related applications: This application is based on Japanese patent application 2010-284495 (filing date: December 21, 2010), and enjoys the priority right of this Japanese application, and by referring to this Japanese application, the entire content of this application is included . technical field [0002] Embodiments of the invention generally relate to ozone generating devices. Background technique [0003] Generally, an ozone generator includes a dielectric tube formed of a dielectric such as glass, and a conductive mold is formed as a first electrode on the inner surface of the dielectric tube. The conductive mold forms a dielectric electrode together with the dielectric tube. A cylindrical second electrode is provided outside the dielectric tube so as to surround the first electrode. A spacer is interposed between the dielectric tube and the second electrode, forming a tiny discharge gap. A source gas containing oxygen flows in the discharg...
