Abstract

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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 177 words
An intermittent ozonizing apparatus comprising: an adsorption-desorption tower; an ozonizer; first conduit means connecting said ozonizer to one end of said adsorption-desorption tower; second recycling conduit means connecting another end of said adsorption-desorption tower to said ozonizer; blower means in said second conduit means for blowing a gas through said second conduit means in a flow direction; an oxygen source; third conduit means connecting said oxygen source to said second conduit means at a position downstream from said blower means; fourth outlet conduit means connected to said second conduit means at a position between said blower means and said third conduit means; and means associated with at least one of said second and fourth conduit means for selectively discharging a gas in said second conduit means to said fourth outlet conduit means, whereby oxygen from said oxygen source is ozonated in said ozoner and said ozonizer is adsorbed at a reduced pressure in said adsorption-desorption tower, and whereby desorbed ozone from said adsorption-desorption tower can be discharged to said fourth outlet conduit means by said blower means.
Claim 2
Dependent Claim 177 words
An intermittent ozonizing apparatus comprising: an adsorption-desorption tower; an ozonizer; first conduit means connecting said ozonizer to one end of said adsorption-desorption tower; second recycling conduit means connecting another end of said adsorption-desorption tower to said ozonizer; blower means in said second conduit means for blowing a gas through said second conduit means in a flow direction; an oxygen source; third conduit means connecting said oxygen source to said second conduit means at a position downstream from said blower means; fourth outlet conduit means connected to said second conduit means at a position between said blower means and said third conduit means; and means associated with at least one of said second and fourth conduit means for selectively discharging a gas in said second conduit means to said fourth outlet conduit means, whereby oxygen from said oxygen source is ozonated in said ozoner and said ozonizer is adsorbed at a reduced pressure in said adsorption-desorption tower, and whereby desorbed ozone from said adsorption-desorption tower can be discharged to said fourth outlet conduit means by said blower means.
Claim 3
Dependent Claim 45 words
An intermittent ozonizing apparatus according to claim 1 wherein said means for selectively discharging comprises a first valve in said second conduit means between said fourth conduit means and said ozonizer, said first valve to be opened during ozone adsoprtion and closed during ozone desorption.
Claim 4
Dependent Claim 32 words
An intermittent ozonizing apparatus according to claim 2 which comprises a second valve in said fourth discharge conduit means, said second valve being closed during ozone adsorption and opened during ozone desorption.
Claim 5
Dependent Claim 17 words
An intermittent ozonizing apparatus according to claim 3 wherein said first and second valves are electromagnetic valves.
Claim 6
Dependent Claim 27 words
An intermittent ozonizing apparatus according to claim 3 including a vacuum device in said fourth discharge conduit means, said vacuum device being actuated only during ozone desorption.
Claim 7
Dependent Claim 20 words
An intermittent ozonizing apparatus according to claim 5 wherein at least one vacuum blower is used as said vacuum device.
Claim 8
Dependent Claim 18 words
An intermittent ozonizing apparatus according to claim 5 wherein a vacuum pump is used as said vacuum device.
Claim 9
Dependent Claim 37 words
An intermittent ozonizing apparatus according to claim 1 including a refrigerator for cooling said adsorption-desorption tower in which said refrigerator is actuated during ozone adsorption to reduce a temperature of an ozone-adsorbent held in said adsorption-desorption tower.
Claim 10
Dependent Claim 36 words
An intermittent ozonizing apparatus according to claim 8 including a heater for heating said ozone-adsorbent in which said heater is actuated during ozone desorption to increase a temperature of said ozone-adsorbent held in said adsorption-desorption tower.
