The coal dry distillation device is provided with a dry distillation device of their invention main body which is provided with an inner tube to which the dry coal is supplied and an outer tube which covers the inner tube, and which indirectly heats the dry coal in the inner tube by means of a heating gas supplied to the outer tube and generates dry-distilled coal and dry distillation gas. This coal dry distillation device is provided with a mercury adsorption suppressing means which suppresses adsorption of mercury contained in the dry distillation gas into the dry-distilled coal, wherein the mercury adsorption suppressing means is an exhaust tube which discharges a gas inside the inner tube. The gas inlet port of the exhaust tube is arranged in a region between the substantially central portion in the longitudinal direction and the coal heating unit outlet in the inner tube.
A coal pyrolysis device including a pyrolysis device main unit including an inner tube to which dried coal is fed and an outer tube which covers the inner tube, and configured to produce pyrolysis coal and pyrolysis gas by indirectly heating the dried coal in the inner tube with heating gas fed into the outer tube, characterized in that the coal pyrolysis device comprises low-mercury-content pyrolysis coal producing means for reducing adsorption of mercury contained in the pyrolysis gas to the pyrolysis coal, or removing the pyrolysis coal to which the mercury has adsorbed, to produce the pyrolysis coal containing a small amount of the mercury.
