Household waste incineration fly ash melting harmless co-treatment system
The invention discloses a household waste incineration fly ash melting harmless co-treatment system which comprises a waste incineration subsystem and a waste fly ash gasification melting harmless treatment subsystem. The waste incineration subsystem conveys collected fly ash to the waste fly ash gasification melting harmless treatment subsystem for gasification melting harmless treatment. Fly ash and a carbon-based fuel form a formed fly ash fuel, the formed fly ash fuel is subjected to an oxidation-reduction reaction through a hot melting gasification furnace to generate fuel gas mainly containing CO and H2 and liquid molten ash residues, and the high-temperature fuel gas is introduced into the waste incineration subsystem as supplementary fuel, so that the fly ash is treated in a harmless mode and recycled in situ, the management and operation cost brought by waste incineration fly ash transfer or chelating landfill is greatly saved, and the operation income of a waste incineration power plant is improved.
本发明公开了一种生活垃圾焚烧飞灰熔融无害化协同处置的系统，包括垃圾焚烧子系统和垃圾飞灰气化熔融无害化处置子系统，垃圾焚烧子系统将收集的飞灰输送至垃圾飞灰气化熔融无害化处置子系统进行气化熔融无害化处理，飞灰、碳基燃料形成成型的飞灰燃料，通过热熔融气化炉进行氧化还原反应，生成以CO、H2为主的燃料气和液态熔融灰渣，将该高温燃料气引入垃圾焚烧子系统作为补充燃料，从而可以就地实现飞灰的无害化处置与资源化利用，大幅节约垃圾焚烧飞灰转运或者螯合填埋带来管理和运营费用，提高垃圾焚烧电厂运营收益。
