再生装置。 A plurality of adsorption towers that receive supply of raw material gas and adsorb and remove impurities in the raw material gas, an inlet switching valve and an outlet switching valve of the adsorption tower provided in the middle of a conduit at the inlet and outlet of the adsorption tower, and the adsorption tower. A regeneration gas supply switching valve and an exhaust switching valve provided in the middle of a conduit for supplying regeneration gas to the tower and a conduit for exhausting the tower;
A bypass valve is provided in the middle of a conduit that communicates with the outlet conduit of the adsorption tower, in which a gas containing a large amount of oxygen is used as the regeneration gas, and the gas contained in the exhaust gas in the conduit for exhausting the regeneration gas is An oxygen analyzer is installed that detects the oxygen concentration in the adsorption column and outputs a valve operation signal when the concentration falls below a predetermined concentration. An adsorption tower regeneration apparatus characterized in that, in the step of replacing gas with purified gas from which impurities have been removed, the exhaust switching valve on the side of the adsorption tower being regenerated is closed in response to a valve operation signal from the oxygen analyzer.
