Water-washing softening system for waste incineration fly ash
The invention discloses a water-washing softening system for waste incineration fly ash. The filtrate outlet of a first-stage centrifuge B is sequentially communicated with a first intermediate water pond, a first reaction pond, a second reaction pond, a decalcification transfer tank and a decalcification centrifuge, wherein the filter cake outlet of the decalcification centrifuge is communicated with a second-stage filtrate tank; the filtrate outlet of the decalcification centrifuge is sequentially communicated with a second intermediate water pond, a water quality stabilization reaction pond, a first-stage stabilization regulating pond, a second-stage stabilization regulating pond, a filtration system, a PH regulating pond, a stabilized water pond, a MVR evaporator and a clean water pond; an alkaline solution storage tank is respectively communicated with the first intermediate water pond and the water quality stabilization reaction pond; sludge outlets of the first-stage stabilization regulating pond and the second-stage stabilization regulating pond are respectively communicated with a slurry storage pond, and the slurry storage pond is communicated with a first-stage filtrate tank through a pipeline. The water-washing softening system for waste incineration fly ash disclosed by the invention solves the problem that the content of chlorine in filter cakes is high, and two portions of sludge are respectively treated and are not deposited to block pipes, the performance is stable and reliable, the treatment effect is good and the quality of outlet water is stable.
