Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] A kind of crystalline anhydrous lithium chloride production method of the present invention, please refer to Fig. 1, concrete steps are:
[0029] a. Solution mixing: Lithium chloride purification solution and lithium chloride magma separation mother liquor are mixed in feed tank 2, in this step the mother liquor that contains the solution of lithium chloride and the separation of lithium chloride magma separation is in the mother liquor of circulation Mixing in the trough;
[0030] b. Forced circulation evaporative crystallization: pump the mixed solution of lithium chloride solution and lithium chloride magma separation mother liquor into the forced circulation evaporative crystallizer 3 and circulate evaporative crystallization at 170°C-180°C to obtain and discharge the magma concentration It is a crystal slurry of 30%-35% solid lithium chloride.
