Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus for regenerating activated carbon, in which used activated carbon, which is used for purifying a cleaning solvent and on which a contaminant is adsorbed, can be regenerated in high production efficiency and further in high energy efficiency.SOLUTION: The apparatus 1 for regenerating activated carbon includes: a hopper 2 into which the used activated carbon is thrown; a plurality of continuous heating furnaces 3 for separating and desorbing a solvent from the used activated carbon; a regeneration furnace 4 for regenerating the solvent-desorbed activated carbon; a solvent liquefaction recovery tank 5 for liquefying/recovering the solvent vapor to be generated from the plurality of continuous heating furnaces 3; and a hot air generator 6 so that the solvent is vaporized/separated stepwise from the activated carbon at different temperatures and then the adsorbed contaminant is removed therefrom to regenerate the activated carbon.
