<p><P>PROBLEM TO BE SOLVED: To provide a production method and production device capable of stably producing an oxygen enriched air for a long period of time without being influenced by moisture in the air when the oxygen enriched air is produced from the air by utilizing an adsorber for adsorbing nitrogen such as a zeolite. <P>SOLUTION: Adsorbers for adsorbing moisture 3, 4, interposing an adsorber for adsorbing nitrogen 2 the adsorbed amount of which increases in accordance with the increase of pressure, are arranged on both sides thereof, the adsorbers are rotated around axial centers thereof, and airs with different pressures are supplied to the adsorbers from the opposite directions, respectively. The airs are passed through the adsorber for adsorbing moisture, the adsorber for adsorbing nitrogen and the adsorber for adsorbing moisture in sequence, the air with relatively increased pressure is subjected to a dehydration treatment, a denitrification treatment, and a moisture enrichment treatment in sequence, and the air with the relatively decreased pressure is subjected to a dehydration treatment, a nitrogen enrichment treatment, and a moisture oxygen enrichment treatment in sequence, thereby enriching oxygen in the air with relatively increased pressure. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
