Coal deactivation processing device

A coal deactivation processing device performing deactivation of coal with a processing gas that includes oxygen, comprising:

• a kiln body provided rotatably into which the coal and the processing gas are supplied;
• and
• a feed pipe provided so as to be able to rotate along with the kiln body, extending along a lengthwise direction of the kiln body, and having a coolant flowing therein, the feed pipe being supported by jigs arranged at a plurality of locations in a lengthwise direction of the kiln body,
• a pair of blades being provided on an outer circumferential section of the feed pipe and protruding in a radial direction, and
• the feed pipe and the pair of blades being arranged so as to pass through an accumulated coal layer of the coal within the kiln body upon rotation of the kiln body, and such that an angle formed by a tangent line of a path along which a central axis of the feed pipe passes and a bisector line of the pair of blades is from 0 to 40°,
• wherein the pair of blades is arranged such that a blade angle formed by one blade of the pair of blades and the bisector line of the pair of blades is from 45 to 85°.
