Classification and main components of the evaporator
The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, which promotes the boiling and vaporization of the liquid; the evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber carries a large amount of liquid foam. After reaching the evaporation chamber in a large space, these liquids can be separated from the vapor by the action of self-condensation or defoamer. Tube condensers are usually equipped with demisters on top of the evaporation chamber.
Evaporators are divided into two types: circulating type and membrane type. According to the movement of the solution in the evaporator, it is divided into circulation type. The boiling solution passes through the heating surface many times in the heating chamber, such as the central circulation tube type, suspension basket type, external heating type, Levin type and forced circulation type. One-way type. The boiling solution passes through the heating surface once in the heating chamber without circulating flow, and the concentrated liquid is discharged, such as rising film type, falling film type, stirring film type and centrifugal film type.
Direct contact type. The heating medium is in direct contact with the solution for heat transfer, such as an immersion combustion evaporator. During the operation of the evaporation device, a large amount of heating steam is consumed. In order to save heating steam, a multi-effect evaporation device and a steam recompression evaporator can be used.
