Abstract
Abstract An ozone-generating apparatus comprises an ozonizer; one or more moisture exchangers in which synthetic zeolite having fine pore diameter for inhibiting adsorption of ozone but easily adsorbing moisture, is filled as a moisture adsorbent; and switching means which switches the moisture exchangers at the inlets and the outlets thereof to alternatively repeat a moisture-adsorbing operation for drying air by passing a wet air through one of the moisture exchanger before feeding it to the ozonizer and a moisture adsorbent-recovering operation for drying the synthetic zeolite by passing the dry ozone-containing air generated from the ozonizer through the other moisture exchanger.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
An ozone-generating apparatus which comprises: an ozonizer; first and second moisture exchangers, connected to said ozonizer, each containing a synthetic zeolite having a pore diameter of less than 4 Angstroms which adsorbs nitrogen oxides, said exchangers alternately repeating an operation for drying air fed into the ozonizer and an operation for regenerating the moisture adsorbent by the dry ozone-containing air obtained by the ozonizer; and, means for feeding nitrogen oxides which is operably connected to said first and second moisture exchangers.
Claim 2
Dependent Claim
81 words
An ozone-generating apparatus which comprises: an ozonizer; first and second moisture exchangers, connected to said ozonizer, each containing a synthetic zeolite having a pore diameter of less than 4 Angstroms which adsorbs nitrogen oxides, said exchangers alternately repeating an operation for drying air fed into the ozonizer and an operation for regenerating the moisture adsorbent by the dry ozone-containing air obtained by the ozonizer; and, means for feeding nitrogen oxides which is operably connected to said first and second moisture exchangers.
Claim 3
Dependent Claim
14 words
An ozone-generating apparatus according to claim 1, wherein nitrogen oxide is NO 2 .
Claim 4
Dependent Claim
23 words
An ozone-generating apparatus according to claim 1, which further comprises: valve means operatively interconnecting said ozonizer and said first and second moisture exchangers.
Claim 5
Dependent Claim
27 words
An ozone-generating apparatus according to claim 1, which further comprises: means for storing said nitrogen oxides which is operatively connected to said means for feeding nitrogen oxides.
Claim 6
Dependent Claim
41 words
An ozone-generating apparatus according to claim 1, which further comprises: means for supplying oxygen to said ozonizer operatively connected to said ozonizer; and means for separating said oxygen from ozone generated by said ozonizer and recycling said oxygen to said ozonier.
Claim 7
Dependent Claim
21 words
An ozone-generating apparatus according to claim 5, wherein said means for separating and recycling said oxygen comprises first and second towers.
