Continuous crystallizer.
Background technique
In the production of actual industrial metaplasia, more commonly used crystallization processes have decrease temperature crystalline and evaporative crystallization.Decrease temperature crystalline and
The solubility of solute in a solvent is all utilized by this characteristic of temperature limiting in evaporative crystallization, and decrease temperature crystalline is that solute is utilized
The characteristics of saturation solubility in a solvent reduces with temperature and reduced, solute is separated from solvent；And evaporative crystallization
It is then by evaporation, the solvent persistently reduced in solution system makes solute concentration reach satiety state with respect to raising, thus
The process that Crystallization Separation comes out from solvent.Temperature change is used than more sensitive solution system typically for solubility and is dropped
Temperature crystallization, and the system insensitive to temperature change for solubility uses evaporative crystallization.
