The principle of evaporation system mainly refers to the process of removing the solvent from the solute by heating the solvent in the solution to be treated, that is, the operation of reducing the water in the solution by heating the solute in the solution. The external heatingevaporator method of is generally to heat the solution to evaporate it to a certain concentration (or saturated solution), and then cool the solution. There will be crystal precipitation. The crystal size and purity of the precipitate are related to the cooling rate. 1. Fast cooling of hot solution or stirring will produce fine crystal particles with higher purity. Seeds can also be added to facilitate crystal formation. 2. Regular crystals with large particles can be obtained by slowly cooling the solution or standing the solution, but the crystal purity is not high. The principle of natural external heating evaporator is that the solution decreases continuously, the solution concentration increases until it is saturated, and then it crystallizes and precipitates. Evaporative crystallization requires heating to evaporate the solvent, heating the solution from unsaturated solution to saturated solution, and then continuing to evaporate. At this time, the excessive solute will precipitate into crystals, which are called evaporative crystallization.
