ABSTRACT:
An apparatus for fluidizing regeneration of activated carbon which has adsorbed therein organic contaminants such as organic amines, organic sulfur compounds and organic solvents. The apparatus comprises; a horizontal grid disposed within the housing thereof; a port for supplying activated carbon as well as a regenerating gas discharge port, both of which are provided in one end wall of the housing; and a regenerating gas supply port and a regenerated activated carbon discharge port, both of which are provided in the other end wall thereof. The interior of the housing is divided by one or more vertical walls into a plurality of chambers, each wall has an opening above the grid through which activated carbon flows, each chamber has a top outlet opening and bottom inlet opening, which are connected to each other by means of a regenerating gas circulating path to form a circulating system for the chamber, each circulating system has a blower and heat exchanger, and the neighboring circulating systems are connected to each other by a gas passage.
