Abstract
An ozone generator of simplified construction comprising a tubular first metallic electrode surrounded by a concentric tubular dielectric member having on its outer surface a second metallic electrode, the dielectric member being longer than the first electrode, and identical end members for slidably receiving and mounting the first electrode and the dielectric member to form an ozone generator, whereby compressive forces are borne by the first metallic electrode.
Claims10
In an ozone generator comprising an inner tubular metallic electrode, an outer electrode comprising a tubular dielectric having on its outer surface an outer metal electrode, said dielectric and said inner electrode defining a corona discharge ozone generation zone, and means for contacting the outer surface of said outer electrode with a cooling fluid, and two end members cooperating with said inner and outer electrodes to form a unitary module, the improvement wherein:
- (a) The longitudinal dimension of said outer tubular dielectric is greater than the longitudinal dimension of said tubular metallic electrode;
- (b) Each of said end members comprises an end plate having:
- (1) On the inner surface thereof a first projection for receiving in slidably engaging, fluid-tight contact said tubular dielectric;
- (2) On the inner surface of said first projection, a second projection for receiving in slidably engaging fluid-tight contact said inner electrode;
- (3) The side wall of said second projection being provided with a circumferential recess extending therearound, and in fluid communication with the annulus between said inner electrode and said dielectric;
- (c) Said end member being further provided with:
- (1) A passage extending from said circumferential recess to the outer face of said end member for transmitting oxygen-containing gas between said annulus and the outside of said module;
- and
- (2) A passage extending from the inner face of said projection to the outer face of said end member for transmitting cooling fluid between the core of said inner cylinder and the outside of said module.
- (d) Means for securing end members being secured by applying to said members an axial compressive force, the axial dimensions of said end members, said tubular metallic electrode and said outer tubular dielectric being such that substantially all of said axial compressive force is applied to said tubular metallic electrode and said tubular dielectric is free to slide longitudinally and is not subjected to said axial compressive force.
