ABSTRACT:
The ozone generating and condensing system includes an oxygen generator for isolating oxygen from an air, an ozonizer provided downstream of the oxygen generator for generating ozone from the oxygen, two parallel-connected ozone absorption towers provided downstream of the ozonizer, an ozone absorption switching mechanism for allowing the ozone to flow into one of the absorption towers from the ozonizer and for recirculating to the ozonizer residual oxygen discharged from the one of the ozone absorption towers after an ozone absorption cycle therein, and an ozone release switching mechanism for introducing the nitrogen generated by the oxygen generator as a carrier gas to the one of the absorption towers after completion of ozone absorption cycle to release the absorbed ozone from the one of the ozone absorption towers and further for causing the released ozone to flow into a reactor tower located downstream of the absorption towers. A purge valve unit is incorporated in the system to purge the carrier gas toward the reaction tower from one of the absorption tower which completes its ozone releasing cycle prior to initiation of its ozone absorption cycle.
