PROCESS AND DEVICE FOR TREATING WASTE MATERIAL

摘要

PROBLEM TO BE SOLVED: To effectively use treated matters by heating chlorine organic matters such as vinyl chloride films without synthesizing any dioxins. SOLUTION: A waste material 16 containing a chlorine organic matter is supplied from one end 4a of a horizontally laid dry distillation oven 4 at a sealed state. The waste material 16 is heated by an electric heating means within a heating temperature range of <=800 deg.C while stirred in the revolving dry distillation oven 4 for dry distillation. Through heating, the waste material 16 emits a dry distilled gas without synthesizing any dioxin. The dry distilled gas is discharged through a dissolution liquid 152. The remaining dry distillation residue 16' of the waste material 16 is allowed to cool by migrating within the dry distillation oven 4, and a chlorine absorbent is added to this to remove chlorine components from the dry distillation residue 16' to inhibit dioxin generation. The dry distillation residue 16' thus obtained is taken out as a high-quality activated charcoal.
