Abstract:
A control system for an ozone generating system includes a temperature responsive portion which is responsive to the temperature of the ozonized gas by interrupting the coupling of high voltage to the electrodes of an ozone generating unit when the temperature of the ozonized gas reaches a level below the temperature at which said ozonized gas rapidly dissociates, the circulation of the gas to be ozonized through said unit continuing during the interruption of high voltage, and a timer sequencing portion for automatically initiating circulation of air through the ozone generating unit a given predetermined period prior to the coupling of high voltage to the electrodes of the ozone generating unit and for automatically terminating the coupling of high voltage to said electrodes of the ozone generating unit a given period prior to termination of air circulation when ozonization is to be terminated.
Abstract:
A unique combination of one and preferably a pair of gas drying units for drying oxygen containing gas to be ozonized and a corona discharge ozone generating unit is provided by a vortex tube unit having an inlet for receiving dried air to be ozonized, a cool air outlet carrying the slow moving molecules of the gas to the inlet of the ozone generating unit and a warm air outlet connected through passageways extending to openings in the drying units for circulating warm air for drying saturated gas drying units. Where two drying units are provided, the air to be dried and ozonized is preferably alternately automatically fed to the inputs of the two drying units, and the warm air outlet of the vortex tube unit is alternately fed through the air drying unit so the drying unit which at a given instant is not receiving air to be dried is itself being dried by warm de-moisturizing air.
