By discussing the flow laws of hot and cold fluids in heat exchangers,changing the flow states of hot and cold fluids,and simulating the precipitation process of mirabilite as the temperature drops,the tem-perature difference of freezing and cooling of sulfate-rich brine in the freezing link is reduced from 16 ℃ to 4 ℃,reducing the power required for freezing by more than 70％.At the same time,the process equipment is optimized to achieve the purposes of initial investment reduction and energy saving and consumption re-duction.
