<p>PURPOSE:To quickly restore adsorption performance by bringing an adsorbent of which the adsorption performance is deteriorated by the carbon component sticking thereto into contact with air or O2-contg. gas heated to 500-650 deg.C thereby burning away the carbon component. CONSTITUTION:Valves 3, 6 are opened and the gas to be dried enters an adsorption column 1 where the moisture is adsorbed by an adsorbent bed 2 and the dry gas is emitted from a dry gas outlet 13 in the stage of adsorbing the moisture. Valves 4, 7 are opened and part 14 of the dried product gas is heated to 200-300 deg.C by a heater 9, then the gas is passed through the bed 2 to desorb the moisture therefrom in the stage of desorbing the moisture. The valves 4, 5 are opened and the O2-contg. gas is fed by a blower 10 and is heated to 500-650 deg.C by a gas heater 8, then the heated gas is passed through the bed 2 to burn away the carbon component sticking thereto in the stage of regenerating the adsorbent. The adsorption performance is thus restored.</p> |
