MVR evaporation system
MVR蒸发器，是英文mechanical vapor recompression的简称。mvr是重新利用它自身产生的二次蒸汽的能量，从而减少对外界能源的需求的一项技术。
MVR evaporator is the abbreviation of mechanical vapor recompression. By reusing energy from second steam to reduce energy requirement from outside.
After compression, pressure and temperature of second steam will be increased as well as the enthalpy. After that, second steam will enter into the heating chamber and used as fresh steam to keep evaporation of the liquid. Therefore, steam will be recycled and heating efficiency will be increased.
2、主要特点 Main characteristics
Main driven power of MVR evaporation system is electric energy. Electric energy transfer to mechanical energy and improve the quality of second steam which is more economic than produce or purchase fresh steam.
Under most of the evaporation process, system no need fresh steam during operation. Only need some steam compensation for pre-heating the raw material when heat energy from product discharged or mother liquid cannot be recycled due to process requirement.
No need independent condenser for second steam condensation, so no need circulating cooling water. Water resource and electric energy will be saved.
Low heat exchange temperature difference and mild evaporation strength, scaling possibility of some product will be reduced.
Evaporation temperature of system can be controlled and very suitable for evaporation an concentration of thermal sensitive product.
Less equipment and compact layout with less occupation.
1）蒸发浓缩evaporation and concentration
2）蒸发结晶evaporation and crystallization
3）低温蒸发low temperature evaporation
4）盐溶液沸点升不超过15度salt solution with boiling point rise no more than 15℃
