FIXED CARBON PRODUCTION DEVICE

摘要

Provided is a fixed carbon production device excellent in operation stability and safety which has high strength and may have a compact device volume, which makes possible production of high-quality fixed carbon with high yields and in large amounts, which is capable of keeping 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-saving efficiency, and which is capable of solving problems due to a tar component. This fixed carbon production device is provided with: a quench chamber for collecting fixed carbon; a dry distillation furnace which is erected and fixed in the quench chamber and into which raw material coal is fed; a dry distillation unit which is polygonal in horizontal cross-section and is partitioned by a separating wall which partitions 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 which partitions the inside of the dry distillation unit in the vertical direction; a 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 coal; and a collection path for collecting fixed carbon collected in the quench chamber.

1. A fixed carbon production device comprising: a quench chamber for collecting fixed carbon; a dry distillation furnace which is erected and fixed in the quench chamber; a dry distillation unit which is partitioned into a rectangular or a polygonal shape in the vertical direction on a horizontal cross-section in the dry distillation furnace by a separating wall from an upper portion to a lower portion; a dry distillation mini-furnace which is partitioned into a rectangular or a polygonal shape in the vertical direction on the horizontal cross-section in the dry distillation unit by a partition from an upper portion to a lower portion; a 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 a collection path for collecting fixed carbon produced in the quench chamber by feeding raw material coal from an upper portion of the dry distillation unit and performing dry distillation in each of the dry distillation mini-furnaces by the pipe-shaped heating means.
