Abstract:
The purpose of the present invention is to provide an inactivation treatment apparatus whereby it becomes possible to produce an inactivated carbide within a short time while preventing the occurrence of spontaneous ignition of coal. The apparatus is equipped with: a rotary kiln main body (103) which is arranged rotatably and in which coal (4) is allowed to flow from an end side toward a tip side; a cooling tube (123) which is arranged rotatably in conjunction with the rotary kiln main body and is provided so as to extend in the direction of the length of the rotary kiln main body, and in which cooling water can flow; and a treatment gas supply tube (131) which is arranged rotatably in conjunction with the rotary kiln main body, and is provided so as to extend in the direction of the length of the rotary kiln main body, and can supply a treatment gas (13) into the rotary kiln main body. In the apparatus, each of the cooling tube and the treatment gas supply tube is so arranged as to move past through a coal layer (5), which is a layer formed as the result of the sedimentation of the coal, in the rotary kiln main body when the rotary kiln main body rotates.
