Title:
蓄熱式廃棄物焼却システム
Document Type and Number:
Japanese Patent JP2004520565
Kind Code:
A
Abstract:
Provided is a regenerative thermal waste incineration system for incinerating industrial waste sludge, urban waste, food refuse and sewage sludge originating from final by-products of chemical factory or sewage treatment plant using a regenerative thermal material. The regenerative thermal waste incineration system includes first and second ceramic layers for accumulating heat from high-temperature gas in backward operation and regenerating accumulated heat to low temperature gas in forward operation, a third ceramic layer and a fourth ceramic layer for accumulating heat from high-temperature gas in forward operation and regenerating accumulated heat to low temperature gas in backward operation, a first waste inlet valve located between the first ceramic layer and the second ceramic layer for introducing waste in forward operation, a second waste inlet valve located between the third ceramic layer and the fourth ceramic layer for introducing waste in backward operation, a burner located between the second ceramic layer and the third ceramic layer for supplying heat for incinerating, a first air valve for introducing air into the system through the first ceramic layer in forward operation, and a second air valve for introducing air into the system through the fourth ceramic layer in backward operation. Since the ceramic layers are directly heated using the exhaust gas that is not brought into direct contact with raw waste, and then the regenerated heat is used for drying and incinerating the waste, the regenerative thermal waste incineration system is a cost-effective system.
