Title:
DRY DISTILLATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/128990
Kind Code:
A1
Abstract:
Provided is a dry distillation apparatus having a high recovery efficiency of tar and pitch, and an excellent energy saving property, wherein a straight cylinder-type furnace is used; inert gas generated in a molten layer on the lower side is used to form a dry distillation layer on the upper side; and an infusible substance can be discharged from the bottom of the furnace during an operation. The dry distillation apparatus is provided with a gasification furnace and a tar and pitch recovery device for recovering tar and pitch from gas generated in the gasification furnace, said gasification furnace having an inlet port for an object to be treated, seal dampers for hermetically dispensing the object to be treated toward the lower side by a predetermined amount, and an inclined floor portion inclined so that the molten substance discharge-side portion is lower than the other portion, said inlet port being provided on the upper portion of the gasification furnace, said inclined floor portion being provided on the lower portion of the gasification furnace. In the gasification furnace, hot air is introduced to the inclined floor portion through an air introduction port provided in the vicinity of the bottom portion, so that at least a molten layer and a dry distillation layer are formed upward in this order on the inclined floor portion. The tar and pitch recovery device separates gas generated from the gasification furnace into tar and pitch, water, and gas.
