A system and method for short link fly ash resource utilization

Abstract

The present application relates to fly ash treatment and resource utilization technical field, disclose a kind of short link's fly ash resource system, including fly ash pulping unit and waste gas treatment unit, the fly ash pulping unit is used to proportionally mix fly ash with water and form uniform slurry, it is connected with dissolving reaction unit by initial pulp discharge pipe, also disclose a kind of energy-saving efficient fly ash water washing dechlorination method, comprising the following steps: S1, pre-solution: a certain amount of fly ash raw ash is weighed by metering scale system and is input into slurry tank, wash liquid from vortex separation unit and reclaimed water from waste water treatment unit are introduced into slurry tank.By optimizing the solid-liquid separation mode in fly ash resource process and the combination of backflow mode between units, the number of equipment and operation process are simplified, and the water consumption is reduced, the energy consumption of the system is reduced, so as to improve the economy and flexibility of fly ash resource.
