ABSTRACT:
A regeneration equipment for spent activated carbon comprises a regeneration reactor provided vertically through a vertical heating furnace and an integrated body of a longitudinal series of numerous spiral elements fixedly provided almost throughout the length of said regeneration reactor. Steam ducts are provided so that they are inserted in said regeneration reactor at about the middle portion thereof. On the outside surface of the wall of said regeneration reactor, fixedly provided are exhaust chambers, each of which communicates at its bottom portion with the inside of said regeneration reactor through exhaust holes provided in the wall of said reactor, and is filled with heat-resisting balls piled up in three layers so that the balls in the top and bottom layers are larger in diameter than said exhaust holes and those in the middle layer are similar in diameter to activated carbon particles. This equipment further comprises a drying hood provided on the top of said heating furnace, said drying hood includes a drying hopper provided through said drying hood and on the top of said regeneration reactor. The drying hopper includes a drying-process waste gas exhaust pipe having an opening in the vicinity of the upper most end of said integrated body of the spiral elements in the regeneration reactor.
