Abstract

PROBLEM TO BE SOLVED: To provide a carbonization furnace capable of converting waste plastics and shredder dust in an inner vessel into a high-purity active carbon by forming the furnace into a double vessel type, increasing the temperature of a combustible gas, simply carrying out the cleaning, repairing and mending due to the separability of the double vessel type into an inner vessel part and an outer vessel part and removing dioxin due to the shutoff of oxygen. SOLUTION: This carbonization furnace for waste plastics and shredder dust is obtained by forming a carbonization furnace into a double vessel type of an inner vessel 14 and an outer vessel 15 and is capable of rotating the inner vessel 14, thereby accelerating the carbonization rate, carbonizing the waste plastics and shredder dust in the inner vessel 14, filling the resultant produced combustible gas in a combustion gas storage tank 16 on the outside with a combustible gas guide tube 3, taking out the combustible gas under a constant pressure with a combustible gas regulator 7, heating the outer vessel 15 with combustible gas burners 8, accelerating the takeout of the combustible gas, shutting off oxygen and thereby removing dioxin.
