The feed liquid is added from the top of the evaporator and flows down the tube wall in a film shape under the action of gravity. During this process, the solvent is continuously evaporated to increase the solute concentration, and its concentrated solution is obtained at the bottom of the heat exchanger.The secondary steam enters the MVR compressor. After being compressed by the compressor, the pressure rises and the temperature rises. It is used as a new heat source to heat the raw material.
1. Short preheating time, without any cross-contact between raw steam and product condensate;
2. The evaporation temperature is low, reaching 45-55℃;
3. The pump flow rate is small, the installed power is small, and the power consumption is low;
4. The concentration time is short, one evaporation process takes 6-10 minutes;
5. High heat transfer coefficient and high evaporation rate;
6. Since there is no liquid column in the heating tube, there is no temperature loss due to the static pressure of the liquid column. Each effect only needs a low heat transfer temperature difference (5~9℃) to operate, which determines this The liquid film heat transfer evaporator has extremely high heat transfer efficiency and evaporation intensity.
