PROBLEM TO BE SOLVED: To provide a fixed carbon production device which has high strength and can have a compact device volume, which can produce high-quality fixed carbon with high yields and in large amounts, which can keep the dry distillation temperature low, which has few restraints in the compositional material, which, having a low dry distillation temperature and low heat input amount, has excellent energy efficiency, and which has excellent safety and operation stability for solving the problem of failure due to a tar component.SOLUTION: A fixed carbon production device includes: a quench chamber 2 for collecting fixed carbon 6; a dry distillation furnace 3 which is erected and fixed in the quench chamber and into which raw material carbon is fed; a dry distillation unit 3 which is polygonal in horizontal cross-section and is segmented by a separating wall 3a which segments the inside of the dry distillation furnace in the vertical direction; a dry distillation mini-furnace which is polygonal in horizontal cross-section and which is partitioned by a partition 3b which partitions the inside of the dry distillation unit in the vertical direction; pipe-shaped heating means which is arranged on the separating wall of the dry distillation unit and the partition of the dry distillation mini-furnace and which dry-distills the raw material carbon; and a collection path for collecting fixed carbon collected in the quench chamber. |
