NITROGEN SUPPRESSION OZONE GENERATOR AND NITROGEN SUPPRESSION OZONE GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a nitrogen suppression ozone generator which promotes an ozone production reaction by adding a micro amount of nitrogen gas.;SOLUTION: A photocatalytic substance having a band gap of 2.0-3.6 eV is prepared in a dielectric or an electrode of a discharge region, and ozone gas is generated by applying an AC voltage from a power source and injecting discharge electric power to the discharge region, supplying oxygen gas to the discharge region together with nitrogen gas which is supplied to the oxygen gas for promoting an ozone production reaction in the range of 10-500 ppm, dissociating the oxygen gas which passes through the discharge region into oxygen atoms by the interaction between discharge light having a light wavelength of at least 344-620 nm which is emitted by an electric discharge and the photocatalytic substance, and bonding the oxygen gas with the dissociated oxygen atoms.;COPYRIGHT: (C)2011,JPO&INPIT
