Introduction of forced circulation evaporating crystallizer

- Nov 10, 2019-

Forced circulation evaporating crystallizer A slurry circulating continuous crystallizer. During operation, the feed liquid is added from the lower portion of the circulation pipe, mixed with the crystal slurry leaving the bottom of the crystallization chamber, and then pumped to the heating chamber. The crystal slurry is heated in a heating chamber (usually 2 to 6 ° C), but evaporation does not occur. The hot crystal slurry boils after entering the crystallization chamber, so that the solution reaches a supersaturated state, so that some solute is deposited on the surface of the suspended crystal grains to grow the crystal. The crystal slurry as a product is discharged from the upper portion of the circulation pipe. The forced circulation evaporative crystallizer has a large production capacity, but the product has a wide particle size distribution.
