Abstract

The invention provides a fly ash treatment system. The fly ash treatment system comprises a pretreatment system, a melting system, a water quenching system and a recovery system, wherein the pretreatment system is used for pretreating fly ash and outputting desalted semi-dry fly ash; the melting system is connected with the pretreatment system and burns Brown gas to heat the desalted semi-dry flyash, so that the desalted semi-dry fly ash forms a high-temperature melt and waste superheated steam; the water quenching system is connected with the melting system and used for performing water quenching on the high-temperature melt and at least outputting a vitreous body and concentrated high-salt wastewater; and the recovery system is connected with the water quenching system and the melting system correspondingly, recovers metal from the waste superheated steam discharged from the melting system and recovers industrial salt from the concentrated high-salt wastewater discharged from the water quenching system. The fly ash treatment system has a better fly ash treatment effect.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment, in particular to a fly ash treatment system. Background technique [0002] Fly ash contains a considerable amount of toxic substances such as dioxins and heavy metals. The "National Hazardous Waste List" determines that fly ash is a hazardous waste, and the number is HW18. [0003] In the prior art, the fly ash is mainly disposed of by landfill stabilization. This treatment method not only occupies a large amount of land, but also can only delay the leaching time of poisons, and it is difficult to fundamentally realize the harmless treatment of fly ash. With the rapid growth of waste incineration, the capacity of landfills for fly ash in many areas has been basically exhausted, which makes fly ash treatment a bottleneck problem that the waste incineration power generation industry urgently needs to break through. [0004] Another way to deal with fly ash in the prior art is c...
