The invention discloses an efficient household garbage
incineration fly ash two-stage washing process. According to the efficient household garbage
incineration fly ash two-stage washing process,
electrolysis dechlorination is performed on
effluent after second-stage rinsing, the
chlorine content of the second-stage rinsing entering first-stage rinsing is reduced, meanwhile, medium-temperature electrolytic plate frame pressing filtering is adopted, the pressing filtering
fly ash water content is controlled to be less than 25%, the
dissolution and adsorption effects of
bound water on
chloride ions are reduced, so that the
chloride ion content in fly ash after the second-stage rinsing is guaranteed to be less than 0.8%, and the requirements for entering a
cement kiln are met; and meanwhile, according to the efficient household garbage
incineration fly ash two-stage washing process, the
chlorine ion dissolution process in the first-stage rinsing process is promoted by reducing the
chlorine ion content in the second-stage rinsing pressing filtering
effluent, and the efficient household garbage incineration fly ash two-stage washing process is one efficient and economical household garbage fly ash washing process.
