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.

主权项

1. A coal deactivation processing device configured to deactivate coal with processing gas containing oxygen, characterized in that the coal deactivation processing device comprises:
a device main body in which the coal flows from one side to another side; processing gas feeding means for feeding the processing gas into the device main body; processing gas circulating means for circulating used processing gas used in the device main body to the processing gas feeding means; and carbon monoxide processing means for adjusting a carbon monoxide concentration in the processing gas such that the carbon monoxide concentration in the processing gas is reduced.
