Title:
廃棄物処理システム
Document Type and Number:
Japanese Patent JP4477758
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive waste treatment system having high reliability, capable of suppressing high-temperature corrosion of a metallic material by hydrogen chloride generated in a decomposition treatment of a polyurethane used as a heat-insulating material and chlorofluorocarbon. SOLUTION: This waste treatment system is equipped with a heat decomposition apparatus 11 for pyrolyzing the polyurethane used as the heat-insulating material expanded by chlorofluorocarbon and a gas-reforming apparatus 12, connected to the heat decomposition apparatus 11, in which pyrolyzed the polyurethane and chlorofluorocarbon of refrigerant is fed. A partial pressure of gas at the vicinity of the outlet of the gas-reforming apparatus 12 is controlled by a partial pressure controller 13. The partial pressure controller 13 controls oxygen partial pressure to a low level.
