First, the material will be pumped into the top of the tube, then fall along the tube’s inwall and forming a liquid film, In this process, the liquid film begins boiling as the tube’s heating, The residual liquid and steam will be separated in the bottom of the tube.
The flow of material in the exchange tube will be determined reasonably to avoid drying tube in the bottom, at the same time, it can ensure the thickness of the film and reach the best heat exchange efficiency and the lowest power consumption.
The falling film evaporator can be used cycle evaporation and single way evaporation
The highest capacity can reach 200T/h per unit.
Suitable for heat sensitivity material.
Suitable for low concentration,low solid content,low scaling material.
High heat transfer coefficient,low temperature difference,vacuum evaporation.
Ensure the material keep boiling in the heat exchange tube,avoid drying wall and scaling caused by intense evaporation.
Low circulation volume,low power consumption.
