description The utility model discloses a fly ash water washing and salt separating crystallization mother liquor treatment system which comprises a crystallization mother liquor collecting tank, a Venturi atomizer, a gas-liquid mixing drying box, a wire mesh demister, a sediment unit, a heat exchanger, an evaporator, a condenser and a centrifugal fan, and further comprises a compressor and a refrigerant. The dry circulating air at 70-90 DEG C is utilized to realize complete solidification of mother liquor, and a specific heat recovery system is utilized to recover part of condensation heat, so that energy is saved, meanwhile, generated condensate water can be used as washing water to be recycled, secondary pollution to the external environment of the system is avoided, and the purpose of full-quantitative treatment in the fly ash washing water salt-separating crystallization process is realized; the method has the advantages of high treatment efficiency, low investment, low operation cost, small occupied area and the li
