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.

Abstract:
PROBLEM TO BE SOLVED: To solve the problem that a series of works such as manufacturing ozone liquid and transport of a medical use container finishing sterility or the like to an sealed container cannot be carried out without causing invasion of bacillus from outside and ozone cannot be positively used in a medical field. SOLUTION: An ozone liquid converter 1 which converts a liquid held in a sealed vessel 3 into ozone liquid includes: a liquid closing pass 5 in which both ends are attachably/detachably connected to the sealed vessel 3 in an internally communicating state and which forms a liquid circulation pathway with the sealed vessel 3; an ozone gas taking in part 11 or the like which is arranged in the middle of the liquid closing pass 5; and an ozone gas discharge part 27 or the like which discharges ozone gas which has not dissolved in the liquid to the outside of the pathway. Since the liquid in the sealed vessel 3 is converted into an ozone liquid and ozone gas does not enter, whereby the container is not broken, and the converter is directly used as a medical application bag for a normal saline solution or injection solvent.

Abstract:
An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).
Abstract:
An apparatus includes a first production line configured to generate aqueous ozone with a first ozone concentration. The apparatus also includes an additional production line configured to generate aqueous ozone with an additional ozone concentration. The first production line and the additional production line include a flow switch, where fluid is configured to flow through the flow switch. The first production line and the additional production line include an ozone generator, where the ozone generator is configured to generate ozone when the fluid flows through the flow switch. The first production line and the additional production line include a fitting coupled to the flow switch and the ozone generator, where the fitting is configured to combine the generated ozone and the fluid to generate the aqueous ozone. The first production line is configured to generate aqueous ozone independently from the additional production line.
Abstract:
A method includes: storing a first flow rate from an oxygen mass flow controller for supplying an oxygen with an ozone generator turned off and measuring a flow rate of the oxygen supplied to the ozone generator, and a second flow rate from at least one ozone mass flow controller provided in flow paths; supplying the ozone into a processing container via the flow paths to perform multiple times a predetermined ozone-based process; acquiring a third flow rate from the oxygen mass flow controller and a fourth flow rate from the at least one ozone mass flow controller, by supplying the oxygen with the ozone generator turned off during a predetermined period between the ozone-based processes; and determining whether the fourth flow rate is a normal value by comparing the first and second flow rates with the third and fourth flow rates, respectively.
