<p>This invention provides a carbonization apparatus which can easily bring a material to be treated to a desired carbonized state, can be installed in a narrow space, and can lower the concentration of a harmful gas contained in a waste gas. The interior of a cylindrical furnace body having a vertically extended axial line (82) is comparted by a partition wall (83) into an upper furnace body which functions as a combustion part (80), and a lower furnace body which functions as a carbonization part (6). Through-holes for supplying carbonization gas to the combustion part (80) are provided in the partition wall (83). In order to render a material (1) to be treated movable by self-weight toward a carbide take-out part (35), the carbonization part (6) is of such a vertical type that a supply part (33) for the material (1) to be treated is disposed in the upper part and the take-out part (35) and a first blowout part (36) for air for self-combustion are disposed in the lower part. An agitating device (39) comprising an agitating member (43), which can be rotated about the vertical axial line, is provided. A premixing combustion part (81) is provided on the combustion part (80) side of the partition wall (83), for mixing a carbonization gas passed through through-holes with a waste gas discharged from a discharge part (34) and burning the mixture. Gas passed through the premixing combustion part (81) is supplied to the combustion part (80).</p> |
