Method and device for chemical-looping incinerating garbage

The invention discloses a method and a device for chemical-looping incinerating garbage. The method comprises the following steps of firstly, pouring the garbage into a fuel reactor, and pretreating;then introducing an oxidation-state oxygen carrier into the fuel reactor, and carrying out oxidation reaction on a treated garbage product and the oxidation-state oxygen carrier; further introducing an oxidation reaction product into a fuel cyclone separator, wherein CO2 and water vapor are used as a fluidizing gas so as to be cyclically imported into the fuel reactor, and a reduction-state oxygencarrier is imported into an air reactor through a classifier; and finally, carrying out reduction reaction on the reduction-state oxygen carrier and air in the air reactor, and re-importing a generated oxidation-state carrier into the fuel reactor for circulating the oxygen carrier. The device comprises the fuel reactor, the air reactor, a first circulator and a second circulator. The method forchemical-looping incinerati
