Abstract

Abstract Ozone is produced when oxygen dissolved or absorbed in an inert liquid dielectric is irradiated with ultra violet (light) energy in the wave length range between 1100 and 2200 angstrom units. The apparatus wherein oxygen gas or air or mixtures thereof, converts a percentage of the oxygen to ozone is composed of special ultra violet 1100 to 2200 angstrom wave length transmitting glass or plastic liquid retainer structural material for the selected inert dielectric liquid used as the absorber liquid for the oxygen, air and ozone gases. The configurations for construction of the apparatus are adinfinitum as flat parallel sheets, paired-corrugated sheets, concentric tubes, etc., any of which control the thickness of the dielectric liquid passing by the source of irradiation.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 93 words
An apparatus for producing ozone comprising means to absorb or dissolve an oxygen containing gas selected from the group consisting of oxygen, air and mixtures thereof in an inert dielectric liquid under superatmospheric pressure to form an oxygen pregnant liquid, a source of ultra-violet radiation having a wavelength between 1100 and 2200 angstrom, transparent conduit means for exposing a stream of said oxygen pregnant liquid as a thin, non-turbulent sheet to said radiation to convert at least a portion of said oxygen to ozone, and means for maintaining superatmospheric pressure throughout the apparatus.
Claim 2
Independent Claim 93 words
An apparatus for producing ozone comprising means to absorb or dissolve an oxygen containing gas selected from the group consisting of oxygen, air and mixtures thereof in an inert dielectric liquid under superatmospheric pressure to form an oxygen pregnant liquid, a source of ultra-violet radiation having a wavelength between 1100 and 2200 angstrom, transparent conduit means for exposing a stream of said oxygen pregnant liquid as a thin, non-turbulent sheet to said radiation to convert at least a portion of said oxygen to ozone, and means for maintaining superatmospheric pressure throughout the apparatus.
Claim 3
Dependent Claim 36 words
The apparatus of claim 1 in which said transparent conduit means is provided with a reflective surface such that radiation passing through the oxygen pregnant liquid is reflected and caused to pass back through the liquid.
Claim 4
Dependent Claim 47 words
The apparatus of claim 1 in which said transparent conduit means is formed with a pair of spaced apart substantially parallel walls between which the sheet of oxygen pregnant liquid flows and wherein said walls are in the form of flat plates, corrugated plates or concentric tubes.
