METHOD AND DEVICE FOR TREATING MIXED WASTE

Japanese Patent JP3544834

B2

PROBLEM TO BE SOLVED: To reduce the inclusion of the decomposition product of a heat medium and thereby enable the reuse of a useful component as a raw material by bleeding an organic halide gas contained in a foam resin and separating/recovering each of components from mixed waste in a heat medium by specific gravity difference.
SOLUTION: Mixed waste including a foam resin containing an organic halide which is used as a heat insulation material in a refrigerator is loaded into a sealing machine 2 which stores a heat modium 1 at a normal temperature, then is sent into a thermal reaction tank 3 to uniformly heat the heat medium 1 at a specified temperature of 300°C or less using a heater 11 arranged encircling the outer wall of the thermal reaction tank 3, and thereby, the foam resin included in the mixed waste is softened or fluidized to bleed an organic halide gas contained in the foam resin. Further, the gas is quenched to separate the components originating from the mixed waste in a specific gravity separation tank 16 into a molten metal 13 and a slid matter 14 by specific gravity difference in the heat medium 1.
