The working principle of falling film evaporator:
Falling film evaporation is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liquid distribution and film forming device. Flow up and down. During the flow, it is heated and vaporized by the heating medium on the shell side, and the generated vapor and liquid phase enter the separation chamber of the evaporator together. After the vapor and liquid are fully separated, the vapor enters the condenser for condensation (single effect operation) or enters the next effect evaporator as a The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.
Features of tubular falling film evaporator:
1. Compact structure, reasonable layout, small footprint, easy installation and operation
2. High production efficiency and large evaporation
3. Significant energy saving effect
4. Fully automatic operation, the control of discharge concentration is very precise
5. The production operation is stable and reliable
