Mechanical vapor recompression (MVR) evaporator & compressor from Leheng
Multiple effect evaporator is the combination of several sets single effect evaporator. The characteristic is to heat the next effect evaporator by used steam produced from the front effect, so as to reduce energy consumption. Usually there is double effect evaporator, three effect evaporator or even more effect evaporation system. More effects with more control points; the driving force of temperature difference at different effect is smaller. The system should be selected according to the job condition.
The multiple effect evaporator can be divided into a common multiple effect evaporation system and a forced circulation multiple effect evaporator. Forced circulation multiple effect evaporator (FCMEE). FCMEE system is designed with several sets external circulation pump based on several sets evaporator; Increasing the flow velocity of the material in the evaporating tube, improving the heat transfer effect and increasing the intensity of evaporation.
