2031201 9009843 PCTABS00002 An ozone generator (14) utilizes one or more cylindrical anodes (66) having disposed centrally therein an elongated cylindrical dielectric tube (58). The dielectric tube (58) is filled with an inert gas at low pressure and contains at a first end thereof beyond the encirclement of the anode (66) a relatively short electrode. In a preferred embodiment, the electrode takes the shape of a cone having the small end (102) thereof coupled through the first end of the dielectric envelope (58) to a source of high energy alternating electric power. The large end of the cone is open and directed toward the far end of the dielectric envelope (58). Electrons are emitted from the electrode and focused down the length of the dielectric envelope (58), creating an electron haze which induces a variety of electron focusing phenomena in an annular reaction space (72) between the dielectric envelope (58) and the encircling anode (66). These electron focusing phenomena include a corona an the outside of the dielectric envelope (58), high voltage spikes between the dielectric envelope (58) and anode (66), and a virtual plasma filling the annular reaction space (72). The electron focusing phenomena induce ozone formation when oxygen bearing feed gas is pumped down the length of the reaction space (72). The exterior of the anode (66) is provided with a water jacket (76) for heat removal. Use of the ozone generator in a water purification system is disclosed for illustrative purposes.
