CARBONIZER FOR WOOD, ETC., AND PYROLYTIC FURNACE USED FOR IT, AND COOLING RECOVERY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a device which can effectively carbonize wood pieces and recover the ingredients of generated wood vinegar, etc., by providing process regions of drying, carbonizing, and combustion within itself, and drying and carbonizing chip-form wood pieces under process, making use of the heat in a combustion process region.;SOLUTION: A carbonizer consists of a pyrolytic furnace A, a cooling recovery system B, and a cyclone C. The pyrolytic furnace A is divided into a hopper 2 of the intake for the chip-form wood 1 to be processed, a drying process region 3, a carbonizing process region 4, and a combustion process region 5 from above. The chip-form wood 1 cast in the hopper 2 goes on to each process region 3, 4, and 5 mentioned above. The chip-form wood 1 is dried in the drying process region 3 by the hot blast sent from the combustion process region 5, and is carbonized in the carbonizing process region 4 to generate smoke gas. The carbide is combusted with an indispensable minimum oxygen in the combustion process region 5. The cooling recovery system B cools the smoke gas sent from the pyrolytic furnace A, liquefies the components of the smoke gas, and recovers the components of the wood vinegar, etc.;COPYRIGHT: (C)2002,JPO
