The main way to promote the use of power continuous evaporation process operation is to use MVR technology, mechanical vapor recompression technology) the use of secondary steam compressor compresses high salt crystallization evaporator separator produced by direct sales, raising steam, compressed steam as a heat source High salt crystallization evaporator, heater heating, and so on. By consuming a small amount of electricity wholesale high salt crystallization evaporator, compressor low-grade steam reforming become a high-grade steam vapor equivalent to a multiple effect evaporator utilization efficiency of 20-30. Evaporator Scope This equipment is widely used in water or an organic solvent solution is concentrated by evaporation of medicine, food, chemical, light industry, especially for heat-sensitive materials (such as water Jianzhi medicine, traditional Chinese medicine alcohol, fruit juice and other liquids) in low temperature and concentrated under vacuum to obtain a high proportion of the extract, and efficient high salt crystals evaporator sales, less wear and tear extract, defoaming good, the heating pipes is not easy scaling, low installation height, less investment advantages.
