Abstract:
An ozone generator module of the electirc discharge field type is provided having at least one cell comprising an assembly of three concentric tubular members, the inner and outer tubular members being electrodes separated by a tubular dielectric member spaced from one of the electrodes a distance sufficient to define a high density electric discharge zone between them, the cell or cells being disposed within a liquid container. Substantially optimum conditions for the production of ozone are provided by making the cross sectional dimension of the field uniform throughout to within a very small range of tolerance and by controlling the temperature of the electrodes by cooling them with liquid coolants one of which is a dielectric liquid, and limiting the density of the field by regulating the voltage across the field and the frequency employed.
Abstract:
A periodically reversed gas flow method and apparatus for ozone production is described. Because moisture reduces the efficiency of most ozonizers, moisture is removed from an oxygen containing fluid before it passes through the ozonizer and the moisture is returned to the oxygen and ozone containing fluid after the ozonizer. At least two moisture adsorbent material columns are used so that the oxygen containing fluid is first passed serially through the two columns with the ozonizer interposed and then periodically reversed to pass serially through the three components in the opposite direction so that at least one column is always in an adsorbent cycle while at least another column is always in a desorber cycle. The pressure of the oxygen containing fluid may be increased immediately upstream of the adsorber column and reduced immediately downstream of the adsorber column, for increased efficiency. The heat of adsorption is transferred from the adsorber column to the desorber column to provide the heat of desorption at the latter column, with the ozonizer serially interposed; the coolant fluid flow is preferably cocurrent to the oxygen fluid flow and reversed everytime that the oxygen containing fluid flow is reversed.
Abstract:
Tubular ozonizer substantially comprising an oxygen chamber, an ozone chamber, a discharge chamber and a coolant container surrounding the discharge chamber bounded by two metal electrodes, which are concentrically telescoped one into the other, have an open upper end and a closed lower end, and have an associated dielectrical tube arranged therebetween so as to leave two discharge spaces. The partition plate between the ozone chamber and oxygen chamber is formed with a bore into which the dielectrical tube is telescoped so as to be radially spaced therefrom, and a packing ring is provided in the annular gap left between the dielectrical tube and the wall of the bore in the partition wall, the packing ring having a centering ring mounted thereon to provide support for the upper flanged edge of the tensionally held, inner electrode.
