Title:
OZONE GAS CONCENTRATION METHOD AND OZONE GAS CONCENTRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/187787
Kind Code:
A1
Abstract:
Provided are an ozone gas concentration method and an ozone gas concentration device (1) that facilitates same, said ozone gas concentration method including; a step in which ozone gas is caused to be adsorbed by an adsorption agent inside a first adsorption vessel (20A); a step in which the interior of a concentration vessel (30) is depressurized in a state in which same does not communicate with the first adsorption vessel (20A); a step in which some of the gas inside the first adsorption vessel (20A) is discharged; a step in which a first concentrated mixed gas is guided inside the concentration vessel (30) by desorbing ozone gas inside the first adsorption vessel (20A) and conveying same to inside the concentration vessel (30); a step in which ozone gas is caused to be adsorbed by an adsorption agent inside a second adsorption vessel (20B); and a step in which the concentration vessel (30) having the first concentrated mixed gas guided therein and the second adsorption vessel (20B) holding the adsorption agent that has adsorbed the ozone gas are switched to a communicated state and the second concentrated mixed gas is guided inside the concentration vessel (30).
