Abstract
A coal deactivation processing device includes: a rotary kiln body provided rotatably into which coal and a processing gas are supplied; and a feed pipe provided so as to be able to rotate along with the rotary kiln body, extending along a lengthwise direction of the rotary kiln body, and having a coolant flowing therein. A pair of blades is provided on an outer circumferential section of the feed pipe and protrudes in a radial direction. The feed pipe and the pair of blades are arranged so as to pass through an accumulated coal layer of the coal within the rotary kiln body upon rotation of the rotary kiln body, and such that an angle formed by a tangent of a path along which the central axis of the feed pipe passes and the bisector of the pair of blades is from 0 to 40 degrees.
