Abstract:
One ozone concentrating chamber is provided therein with a part of a cooling temperature range where ozone can be selectively condensed or an oxygen gas can be selectively removed by transmission from an ozonized oxygen gas, and a part of a temperature range where condensed ozone can be vaporized, and condensed ozone is vaporized by moving condensed ozone with flow of a fluid or by gravitation to the part where condensed ozone can be vaporized, whereby the ozonized oxygen gas can be increased in concentration. Such a constitution is provided that a particle material 13 for condensation and vaporization filled in the ozone concentrating chambers 11 and 12 has a spherical shape of a special shape with multifaceted planes on side surfaces, or an oxygen transmission membrane 130 capable of selectively transmitting an oxygen gas in an ozone gas is provided.

Abstract:
An apparatus for producing high-concentration ozone gas has a plurality of adsorption/desorption columns and a plurality of valves capable of switching opening/closing of the passage of gas flowing into or out of the adsorption/desorption columns, such that each of the adsorption/desorption columns can performs ozone adsorption processing, evacuation processing or desorption processing. At least two of the adsorption/desorption columns are placed in a serial cycle arrangement to constitute a main adsorption/desorption column group, and one or more of the other adsorption/desorption columns is placed in parallel with the main adsorption/desorption column group to constitute an auxiliary adsorption/desorption column. The auxiliary adsorption/desorption column performs desorption processing during a period in which none of the adsorption/desorption columns of the main adsorption/desorption column group is performing desorption processing.
