Pickling apparatus and pickling method

Provided is a device for the destructive distillation of coal, said device suppressing increases in the concentration of mercury within destructively distilled coal generated by the device. The device for the destructive distillation of coal is a rotary kiln in which an inner cylinder is rotatably supported inside an outer cylinder, thermal gas is supplied to interior of the outer cylinder and dried coal is supplied to the interior of the inner cylinder from one end side thereof, the dried coal is subjected to thermal destructive distillation while being moved and agitated from the one end side of the inner cylinder to the other end side thereof due to the inner cylinder being rotated, and destructively distilled coal and destructively distilled gas are delivered from the other end side of the inner cylinder.
