MVR evaporation system
MVR蒸發器，是英文mechanical vapor recompression的簡稱。mvr是重新利用它自身產生的二次蒸汽的能量，從而減少對外界能源的需求的一項技術。
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、主要特點 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）蒸發濃縮evaporation and concentration
2）蒸發結晶evaporation and crystallization
3）低溫蒸發low temperature evaporation
