摘要： The present invention provides a double-cylinder type apparatus for the regeneration of active carbon, which comprises a heating furnace provided with at least one burner and at least one annular regeneration chamber composed of at least one set of an inner cylinder and an outer cylinder installed concentrically inside said heating furnace, said outer cylinder having a plurality of holes penetrating the side wall thereof, wherein the spent active carbon is supplied to the upper part of said annular regeneration chamber and the regenerated carbon is to be taken out at the lower part of the same. The heating of said annular regeneration chamber from the side of said inner cylinder is performed either by introducing the flue gas arising in said heating furnace into the inner cylinder or by providing at least one burner within said inner cylinder and utilizing the combustion gas from said burner. The spent active carbon can be regenerated by subjecting the same to the process comprising drying, calcination and reactivation by the use of the flue gas.

摘要： The apparatus comprises an outermost, an intermediate, and an innermost compartment, the outermost compartment being provided with burners, activated carbon being supplied into, treated in, and removed from the intermediate compartment, and there being communication for gas between the three compartments. In revivification by the direct heating process, reactor gas is supplied into the outermost compartment, heated by the burners, passed into the intermediate compartment to contact the activated carbon being treated, and is then passed into the innermost compartment and exhausted therefrom. In revivification by the indirect heating process, reactor gas is supplied into the innermost compartment, passed into the intermediate compartment for treatment of activated carbon, and then passed into the outermost compartment and is exhausted therefrom, the innermost and intermediate compartments and elements therein being indirectly heated by the burners of the outermost compartment.
