METHOD AND APPARATUS FOR TREATING REFUSE BY CARBON DIOXIDE

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for treating refuse with carbon dioxide while suppressing the generation of dioxins. SOLUTION: A refuse treatment chamber 1 and a gas heating tank 10 are provied and the gas heating tank 10 is equipped with an electric heater 11 for heating a heat accumulation material 13 and a heat transfer pipe 12 heated by the heat accumulation material 13 and a gas supply part 2 of carbon dioxide G is connected to the inlet of the heat transfer pipe 12 and the refuse treatment chamber 1 is connected to the outlet of the heat transfer pipe 12. The gas supply part 2 is equipped with a gas cylinder 3 filled with carbon dioxide G and carbon dioxide G is sent to the heat transfer pipe 12 from the gas cylinder 3 and the gas heating tank 10 heats carbon dioxide G sent to the heat transfer pipe 12 to form high temperature carbon dioxide (high temperature gas g1) and refuse D is heat-treated by the high temperature gas g1, which is sent from the gas heating trank 1, in the refuse treatment chamber 1.
