The flow of the evaporation process can be divided into several categories according to the pressure
The heating medium is in direct contact with the solution for heat transfer, such as immersion combustion evaporator.
Evaporation device in the course of operation, to consume a lot of heating steam, in order to save the heating steam, can be used multi-effect evaporation device and steam recompression evaporator.
The boiling solution is heated in the heating chamber at one time by heating the surface without circulation, that is, discharging the concentrate, such as the rising film type, falling film type, stirring film type and centrifugal film type.
The boiling solution is heated several times in the heating chamber through a heated surface, such as a central circulation tube, a hanging basket type, an external heat type, a column type, and a forced circulation type.
