METHOD FOR TREATING POLYCHLORINATED BIPHENYL-CONTAMINATED WASTE OIL, METHOD FOR TREATING POLYCHLORINATED BIPHENYL-CONTAMINATED SOLID, EQUIPMENT FOR TREATING POLYCHLORINATED BIPHENYL WASTE OIL AND EQUIPMENT FOR TREATING POLYCHLORINATED BIPHENYL-CONTAMINATED SOLID

摘要

PROBLEM TO BE SOLVED: To provide a method and equipment which permit PCB-contaminated waste oil and PCB-contaminated solids to be safely and surely detoxified and fuel gases to be collected from the PCB-contaminated waste oil for effective use.;SOLUTION: The thermal cracking section 52 of a gasification melting furnace 50 thermally cracks and gasifies compressed blocks and PCB-contaminated waste oil, a gas reforming section 53 reforms generated gases, and a melting section 54 melts the compressed blocks and incombustibles of a trace quantity of PCB-contaminated waste oil. A supply device supplies the PCB-contaminated waste oil to the thermal cracking section 52 in a supply quantity accounting for ≤20 wt.% of the supply quantity of the compressed blocks.;COPYRIGHT: (C)2012,JPO&INPIT
