Rising film evaporator

How the rising film evaporator works

The structure of the rising film evaporator is that the liquid enters the heating pipe according to the principle of the siphon pump, and the liquid and the steam are separated after flowing into the separator, and flows back to the evaporator through the circulation pipe to form a closed circuit cycle. Therefore, the evaporator is further It is called the external circulation evaporator.

The heating pipe of the rising film evaporator is composed of a heat exchange tube, and the raw material liquid is preheated to reach the boiling point or near the boiling point, and is introduced from the bottom of the heating chamber, and is driven by the secondary steam which rises at a high speed, and evaporates along the inner wall of the heat exchange tube, and is heated. The top of the chamber can reach the required concentration, and the finished liquid is discharged from the bottom of the separation chamber, and the generated secondary steam is set as the next heat source after being disposed in the upper separation plate group to remove bubbles, water drops and debris.https://www.heczb.com/
