Ozone generator

DETAILED DESCRIPTION Having now described my invention and the manner in which it may be used, I claim: 1.
An ozone generator comprising: (a) an elongated hollow housing closed at both ends, (b) an air inlet adjacent one end of the housing, (c) an ozone outlet adjacent the opposite end of the housing, (d) a plurality of elongated electrode assemblies in the housing extending longitudinally therein and spaced apart from each other, and (e) an electrically non-conductive air barrier wall disposed transversely within the housing intermediate the ends of the housing and electrode assemblies, forming a seal about the inner wall of the housing and the outer surfaces of the outer electrodes of the electrode assemblies for preventing the passage of air between the spaced electrode assemblies from the air inlet to the ozone outlet, (f) each electrode assembly comprising: (1) elongated inner and outer electrodes of tubular form disposed concentrically with respect to each other and arranged for connection across a source of high voltage, (2) an elongated insulator member of dielectric material of tubular form disposed concentrically between the inner and outer electrodes and forming with one of said electrodes an elongated passageway therebetween communicating at one end with the air inlet end of the housing and at the opposite end with the ozone outlet end of the housing, and (3) a multiplicity of spaced protrusions on the surface of one of the electrodes facing the other electrodes, forming a multiplicity of electrical discharge points between said electrodes.
2.
The ozone generator of claim 1 wherein the inner surface of the outer electrode and the outer surface of the tubular insulator are smooth, the multiplicity of protrusions project outwardly from the inner tubular electrode of each assembly, the opposite ends of the tubular insulator member are sealed against the entrance of contaminants, and the air passageway is formed between the confronting smooth surfaces of the tubular insulator member and outer electrode
