Coal deactivation treatment device

摘要

A coal deactivation treatment device for deactivating of coal by means of a treatment gas that is a mixture of air and nitrogen gas is provided with, among other things: a treatment column inside of which coal flows from the top to the bottom; treatment gas feed means, and the like, for feeding treatment gas to the inside of the treatment column; humidifying heaters for heating and humidifying the treatment gas such that the treatment gas fed to the inside of the treatment column can maintain a relative humidity of 35% or greater, even at 95° C.; a temperature sensor and a control device for adjusting the temperature inside the treatment column such that the inside of the treatment column is maintained at a relative humidity of 35% or greater and a temperature of 95° C. or lower.

主权项

1. A coal deactivation processing apparatus configured to deactivate coal with a processing gas containing oxygen, comprising:
an apparatus main body in which the coal flows from one side to another side; processing gas feeding means for feeding the processing gas into the apparatus main body; processing gas humidifying heating means for heating and humidifying the processing gas to be fed into the apparatus main body in such a way that a relative humidity of the processing gas is maintainable to be 35% or more even when a temperature of the processing gas is 95° C.; and apparatus main body internal-environment adjusting means for adjusting a temperature inside the apparatus main body in such a way that the relative humidity inside the apparatus main body is 35% or more and the temperature inside the apparatus main body is 95° C. or less.
