Embodiment Construction
[0031] See attached Figure 1~3 , a fly ash harmless treatment resource recycling device, which includes sequentially connected solid-phase catalytic dechlorination detoxification and removal of dioxin system Ⅰ, waste incineration fly ash three-stage water elution desalination system Ⅱ, heavy metal removal system Ⅲ, membrane Distillation concentration system IV and salt crystallization system V; the solid-phase catalytic dechlorination detoxification and dioxin removal system uses mineral catalysts to induce dioxin dechlorination and remove dioxins in fly ash. After dechlorination, the phenyl parent A non-toxic and harmless high-polymer product is generated through a condensation reaction; the waste incineration fly ash three-stage water elution desalination system washes off a large amount of salt in the fly ash from which dioxins have been removed, and in the three-stage water washing filtrate after water washing There are also some heavy metal ions remaining; the heavy meta...
