Multistage incineration equipment of rotary kiln garbage gasifying and carbon ash cosmelting

A multi-stage incineration equipment equipped with a rotary kiln for refuse gasification and carbon-ash co-fusion relates to the technical field of environment protection, which comprises a rotary kiln gasification furnace which consists of a kiln body, a hopper, a hydraulic valve, a piston feeder, a refuse inlet, a kiln-tip friction seal, a tail frication seal, an ash outlet, a scraper, a sorter and a disintegrator, a high temperature fusion combustion furnace consisting of a combustion chamber, a gas inlet, a fuel burner nozzle, a pneumatic delivery pump, a tangential second air port, a second blower and a slag water pound and, an flue gas purification equipment consisting of a quenching chamber, a water spray pipe, a flue gas purification tower, a slaked lime tank, a slaked lime spray device, an active carbon tank, an active carbon spray device and a bag dust catcher. The utility model not only radically eliminates a fly ash source which acts as the media to promote the generation of dioxin and heavy metal but is capable of increasing the carbon conversion ratio for the system combustion without increasing basically the energy consumption. Further, the utility model can realize a single recovery of metal resource.
