Disclosed is a carbonizing device capable of eliminating the possibility of leakage of a carbonization gas to the outside of the device and the possibility of explosion of the gas. Specifically disclosed is a carbonizing device which comprises heating chambers (21 to 24) that heat an object to be processed so as to thermally decompose the object; preliminary chambers (11, 12) that are disposed between the heating chambers (21 to 24) and the outside of the device and that is used for carrying the object to be processed from the outside into the heating chambers (21 to 24) while the heating chambers (21 to 24) are substantially shielded from the outside; a plurality of cooling chambers (31 to 33) in which processes subsequent to the thermal decomposition of the object to be processed are performed; shielding doors (5) each closing the preliminary chambers (11, 12), the heating chambers (21 to 24), and the cooling chambers (31 to 33) aligned in series; a conveying means that opens and closes the shielding doors (5) and conveys the object to be processed; and exhaust pipes (3) that extract gas ejected from the preliminary chambers (11, 12), the heating chambers (21 to 24), and the cooling chambers (31 to 33). In the carbonizing device that carbonizes the object to be processed while the object to be processed sequentially passes through the preliminary chambers (11, 12), the heating chambers (21 to 24), and the cooling chambers (31 to 33), the preliminary chambers (11, 12) are kept unheated. |
