PURPOSE: A manufacturing apparatus for activated bamboo charcoal is provided to be able to rapidly form more micro pores by supplying a part of the exhausted gas including carbon monoxide to the region in an outlet part of a rotary kiln furnace with reflux. CONSTITUTION: A manufacturing apparatus for activated bamboo charcoal comprises a rotary kiln furnace (2); a burner (3); a reflux gas supply pipe (20); an outer container (30); a steam supply pipe (31); and a steam discharging hole (32). The reflux supply pipe is installed within the rotary kiln furnace so that the exhausted gas is collected by a blower in an outlet part of the rotary kiln furnace to supply the reflux gas including carbon monoxide to the rotary kiln furnace. The steam supply pipe is formed through the outer container toward the outer periphery of the rotary kiln furnace. The steam discharging hole is punched on one side of the outer periphery of the rotary kiln furnace, and open only when the steam discharging hole corresponds to the steam supply pipe by rotation of the rotary kiln furnace so that steam is supplied according to the rotation cycle of the rotary kiln furnace. The steam supply pipe and the steam discharging hole are formed to supply steam on an emission aperture of the reflux gas supply pipe within the rotary kiln furnace. |
