COAL DEACTIVATION PROCESSING DEVICE AND EQUIPMENT FOR PRODUCING MODIFIED COAL USING SAME

摘要

Provided is a coal deactivation processing device that can suppress an increase in carbon monoxide concentration in processing gas regardless of the fact that used processing gas is circulated and refused. The present invention is provided with: a device main body (141) that causes coal therewithin to flow from one side to another; a processing gas feed means (142-144, 144a, 145,145a, 146, 146a, 147, 148) that feeds processing gas to the interior of the device main body (141); a processing gas circulation means (148) that circulates used processing gas (33) used in the device main body (141) to the processing gas feed means; and a carbon monoxide processing device (170) that adjusts the carbon monoxide concentration in the processing gas in a manner so as to reduce the carbon monoxide concentration in the processing gas.
