To provide the subject unit miniaturized as practicably as possible, causing no high cost of active carbon production, and bringing about no environmental problems.
This active carbon production/regeneration unit has such a scheme that the inside of a rotary kiln 1 is served as a reaction chamber 27 and heating pipes 15 are set up so as to traverse the reaction chamber 27; a high-temperature gas heated in a circulating gas heating device 8 is allowed to flow through the heating pipes 15 to heat the pipes 15, and the inside of the reaction chamber 27 is kept at the activation temperature by the aid of the radiated heat from the heating pipes 15; the steam sprayed via a steam inlet pipe 20 acts as an activation gas in the reaction chamber 27 and is finally exhausted via an activation gas exhaust pipe 17; a carbonaceous material 25 is fed from a carbonaceous material hopper 22 into the reaction chamber 27, the inside of which stands at the activation temperature and in an activation gas atmosphere, being in continuous rotation; the carbonaceous material 25 is activated under transfer from position A toward B-direction while being subjected to scraping-up agitation with a scraping-up blade 6, and finally, discharged via an active carbon discharge port 18.
