Product Description
The function of the single-effect falling film evaporator is to separate the ethanol from the feed liquid and condense and recover the extraction liquid through reduced-pressure vacuum evaporation. The single-effect falling film evaporator used for the production of ethanol solution is different from the general single-effect falling film evaporator for the production of aqueous solution. Ethanol has a lower boiling point and is volatile. Evaporation is easy to evaporate especially under vacuum and reduced pressure, so its evaporation area Smaller, the condensation recovery of alcohol vapor is more difficult, so the plate heat exchanger with higher heat exchange efficiency. In order to obtain a good cooling effect, a two-stage or multi-stage method is often used for cooling and recovery, which is also different from general aqueous solution evaporation.
Working Principle
Falling film evaporator can be used for solutions with higher viscosity, so the concentration of the discharged solution is higher than that of the natural circulation evaporator. Falling film evaporator has a large heat transfer coefficient and is not greatly affected by changes in the heat transfer temperature difference. It can be operated at a wide heat transfer temperature, so the heat transfer temperature difference can be changed to adapt to the unstable feed liquid volume. Falling film evaporator has the advantages of compact equipment, small heat transfer area, small amount of liquid storage, not easy to scale, and strong adaptability to easy foaming solutions.
