  • Intermittent ozonizing apparatus
    Patent number: 4462965
    Abstract: An intermittent ozonizing apparatus comprises an ozonizer for producing ozonized oxygen from an oxygen source, an adsorption-desorption tower which adsorbs ozone from the ozonized oxygen fed from the ozonizer to store the ozone, the ozone being desorbed by suction under a reduced pressure, a recycling passage for returning oxygen to the ozonizer after the ozone is adsorbed in the adsorption-desorption tower, and a blower connected in the recycling passage whereby oxygen gas containing ozone is recycled to the ozonizer during ozone adsorption and the ozone stored in the adsorption-desorption tower is desorbed by suction under a reduced pressure during ozone desorption to feed to an ozone outlet.
