ABSTRACT:
The present invention provides an apparatus, and a method for the regeneration of spent wet active carbon, which apparatus comprises a drier for substantially drying the spent carbon, a heating furnace provided with at least one burner and at least one duct, and a regeneration chamber consisting of at least one set of inner cylinder and outer cylinder installed concentrically and vertically inside said heating furnace to penetrate the top and bottom walls of the furnace, wherein said inner and outer cylinders have respectively a multiplicity of holes penetrating the side walls thereof, said inner cylinder is connected with a supply tube for a regeneration gas capable of effecting regeneration of the dried carbon-to-be-regenerated upon contact therewith, the upper end of said outer cylinder is connected with said drier so as to receive said dried carbon therefrom while the lower end thereof forms an outlet for the regenerated carbon, and said duct is connected with the drier so as to facilitate direct or indirect utilization of the sensible heat of the combustion exhaust gas in drying the spent active carbon.
