ABSTRACT:
A concentric tube ozonator which is designed from theoretical considerations to produce ozone efficiently with minimum electrical power consumption. Concentric tube assemblies in the ozonator are designed for ease of construction and replacement of the components thereof, with each concentric tube assembly providing for the relatively precise positioning of the components therein as is required for proper and efficient operation of the ozonator. Each concentric tube assembly is constructed with an outer tubular metal electrode and an inner tubular metal electrode positioned concentrically within the outer tubular electrode. A glass dielectric tube is positioned concentrically and centrally between the outer and inner tubular electrodes. This construction provides an inner concentric annular electrical field discharge gap between the glass dielectric tube and the inner tubular electrode, and an outer concentric annular electric discharge gap between the glass dielectric tube and the outer tubular electrode, in which the feed gas is converted into ozone. The efficiency of the ozonator is optimized by constructing the ozonator such that the inner and outer annular discharge gaps are maintained in the range of 0.45 mm to 0.55 mm, preferably at 0.5 mm, to provide a minimum discharge gap to convert oxygen to ozone to minimize the voltages required during operation thereof.
