COAL DRY-DISTILLATION DEVICE AND MODIFIED COAL PRODUCTION EQUIPMENT USING SAME

摘要

A rotary kiln-type coal dry-distillation device that: rotatably supports an inner tube inside an outer tube; supplies heating gas to the interior of the outer tube; moves dried coal from one end side of the inner tube to the other end side, and agitates and dry-distills the dried coal under heat by supplying the dried coal from the one end side of the inner tube to the interior, and rotating the inner tube; sends out dry-distilled coal and dry-distilled gas from the other end side of the inner tube; and has provided therein a pulverized coal supply device that supplies pulverized coal having a particle diameter of no more than 100 μm to the interior of the inner tube, such that the volume of the pulverized coal is 1-10 wt % relative to the amount of dry-distilled coal sent from the other end side of the inner tube.

主权项

1. A rotary kiln-type coal pyrolysis device that rotatably supports an inner tube inside an outer tube and that pyrolyzes under heat while moving and agitating coal from one end side of the inner tube to another end side thereof by rotating the inner tube upon heating gas being supplied to an interior of the outer tube and upon the coal being supplied from the one end side of the inner tube to an interior thereof, so as to send out pyrolyzed coal and pyrolyzed gas from the other end side of the inner tube, the coal pyrolysis device, comprising:
a pulverized coal supply means that supplies pulverized coal having a particle diameter of less than or equal to 100 μm to the interior of the inner tube, such that a volume of the pulverized coal is 1-10 wt % relative to an amount of the pyrolyzed coal sent from the other end side of the inner tube.
