Coal deactivation processing device

摘要

The present invention makes it possible to prevent the spontaneous combustion of coal while causing oxygen to be adsorbed to the surface of the coal in an efficient manner. A coal deactivation processing device is provided with: a rotary kiln body (103) that is capable of rotation and into which coal and a processing gas are supplied; a feed pipe (142) that is provided so as to be capable of rotating together with the rotary kiln body (103), that extends along the lengthwise direction of the rotary kiln body (103), and within which a coolant flows; and a hat (143) that is provided to the outer circumferential section of the feed pipe (142) so as to protrude toward the rotation direction of the feed pipe (142). The feed pipe (142) and the hat (143) are arranged so as to pass through a coal layer resulting from the accumulation of coal (2) within the rotary kiln body (103) when the rotary kiln body (103) rotates.
