METHOD OF MAKING ZINC-CONTAINING WASTE INTO RAW MATERIAL UTILIZING WASTE PLASTIC CONTAINING VINYL CHLORIDE SUCH AS ASR AS HEAT SOURCE AND CHLORINE SOURCE

摘要

PPROBLEM TO BE SOLVED: To make waste plastics containing vinyl chloride resin such as ASR (Automobile Shredder Residue) into a heat source and a chlorine source without sorting, dry distillation or dechlorination process and to make lead contained in zinc-containing waste into resources as raw materials for refining zinc or lead by being subjected to chlorination volatilization. PSOLUTION: Pulverized waste plastics containing vinyl chloride such as ASR are directly blown into the high temperature part within a chlorination reaction furnace for Zn-containing waste, thus are effectively utilized as a heat source and a chlorine source in chlorination volatilization reaction, and heavy metals in the Zn-containing waste and the waste plastics such as ASR are separated into a Zn refining raw material and a Pb refining raw material.
