no. 1 approach

[0025] based on figure 1 A first embodiment of the coal deactivation processing apparatus of the present invention will be described.

[0026] Such as figure 1 As shown, a supply chamber 112 for supplying the coal 1 to the inside of the processing tower 111 is provided on the upper part of the processing tower 111 through which the carbonized coal 1 flows from the upper side to the lower side. In the lower part of the processing tower 111, there is provided a cooling chamber 113 which receives the processed coal 2 flowing through the inside of the processing tower 111 and discharges it after being cooled.

[0027] On the upper side (one side) above the center of the processing tower 111, a plurality of upper sides that transfer the oxygen-containing processing gas 5 to the upper side than the center of the processing tower 111 are respectively connected along the vertical direction. The head end side of the introduction pipe 121 that is introduced into the inside of the proc...

Abstract

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.

Description

technical field [0001] The present invention relates to a coal deactivation treatment device for deactivating coal with treatment gas containing oxygen. Background technique [0002] Carbonized coal is easily bonded to oxygen due to surface activation, and if stored as it is, it may spontaneously ignite due to the heat of reaction with oxygen in the air. Thus, by exposing dry-distilled coal to an oxygen-containing treatment gas atmosphere, oxygen is first bonded to the surface of the coal to deactivate the coal and prevent spontaneous combustion during storage. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2007-237011 [0006] Patent Document 2: International Publication No. 95 / 13868 Pamphlet Contents of the invention [0007] The problem to be solved by the invention [0008] If the above-mentioned coal is intended to be deactivated as described above, in the initial stage, the coal may react easily ...
