Title:
Coal inactivation processing unit
Document Type and Number:
Japanese Patent JP6226422
Kind Code:
B2
Abstract:
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 includes: a rotary kiln body provided rotatably into which coal and a processing gas are supplied; 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 (103), and having a coolant flowing therein, and a protruding portion provided to the outer circumferential section of the feed pipe so as to protrude toward the rotation direction of the feed pipe. The feed pipe and the protruding portion are arranged so as to pass through a coal layer resulting from the accumulation of coal within the rotary kiln body when the rotary kiln body rotates.
