METHOD AND APPARATUS FOR PRODUCING OZONE BY CORONA DISCHARGE

摘要

The present invention relates to an apparatus (10) and method for producing ozone from a feed gas containing molecular oxygen by means of a corona discharge. The apparatus (10) and method comprise passing the feed gas (220) between two concentric tubes (20, 60) of a dielectric material. The inner tube (20) contains an electrode (30) with a plurality of windings of a conductive wire electrode around its inner surface (21) or a central rod inside its inner surface (21). The outer tube (60) has a plurality of windings (70) of a conducting wire electrode around its outer surface (62). Both electrodes are connected to a high voltage AC electric current device (280), whereby the current flowing between the electrodes (30, 70) through the dieletric tubes (20, 60) and the passing feed gas converts at least some of the molecular oxygen in the feed gas to ozone. This method and apparatus (10) for generating ozone have the advantages of being low cost, reliable, energy efficient, simple, compact, and easy to use and maintain.
