The invention relates to a
fly ash recycling
system and method. The
system comprises a
fly ash curing subsystem for curing and forming
fly ash raw materials into cured ash, a
water washing subsystem, a
water washing liquid post-
treatment system and a wet ash post-treatment subsystem, the washing subsystem comprises a washing hopper, n stages of washing liquid barrels and a pump, the washing hopper comprises a filter screen, a liquid
distributor, an air
pipe and a supporting plate, the liquid
distributor is connected with an inlet
pipe, the bottom of the washing hopper is connected with an outlet
pipe, an inlet of the pump is connected with the outlet pipe and an outlet of each stage of washing liquid
barrel, and an outlet of the pump is connected with the inlet pipe and an inlet of each stage of washing liquid
barrel. Valves are respectively arranged on the inlet pipe and the outlet pipe, and valves are respectively arranged on pipelines of an inlet and an outlet of each stage of washing liquid bucket. According to the
system and method,
solid-liquid separation is easy to achieve after
water washing, the water-
cement ratio in the water washing process is low, water in all stages of water washing liquid buckets is recycled, and the system and method have the advantages of being good in technological process economical efficiency, more convenient to operate, low in
energy consumption cost, efficient and the like.
