Carbonizing furnace for processing wood vinegar and method for producing wood vinegar using the same

摘要

Disclosed herein are a carbonizing oven for processing pyroligneous liquor and a method for preparing pyroligneous liquor using the same. More specifically, the present invention provides a carbonizing oven which exhibits a high yield of pyroligneous liquor due to no thermal loss and is not only capable of improving working efficiency due to the feasibility of a continuous process but is also capable of significantly preventing environmental contamination. For this purpose, the carbonizing oven is so configured that a raw material is processed into a proper size using a grinder chopper, the chopped raw material is introduced into an airtight combustion chamber, the thus-transferred raw material is carbonized and dried using an ignition device such as a burner, and the dried material is cooled and stored, while main ingredients of pyroligneous liquor, contained in combustion gases generated during the carbonization process, are subjected to low-temperature condensation to thereby recover the pyroligneous liquor, the residue is re-combusted in the recombustion chamber to thereby minimize the emission of noncombustible volatile materials in combustion gases discharged to the outside, and simultaneously the combustion gases are recycled into the combustion chamber such that a temperature of the combustion chamber can be elevated.
