MVR蒸发系统概述/MVR evaporators overview
       MVR蒸发系统（mechanical vapor recompression）的简称，蒸发器产生的二次蒸汽经过压缩后再利用的新型蒸发器。只需开车启动将物料加热到蒸发温度即可蒸发，正常运转时基本无需外界能源，蒸发浓缩领域中的能耗节约的新技术。早在60年代，徳国和法国已经开始的将该技术应用于化工、制药、造纸、污水处理、海水淡化等行业。
       本MVR蒸发系统采用蒸汽或电热装置进行启动加热；PLC自动控制；随时开机、停机，自动化程度高。
It is Short for MVR evaporator (mechanical vapor recompression). It is a new kind of evaporator which may reuse secondary steam (after compression after compression) produced by the evaporator after compression. You only need to start up the equipment and heat the material to evaporation temperature. Almost no external energy source is needed for normal operation. This is a new kind of technology which requires least energy in evaporation and concentration area. Since 1960s, Germany and France have begun to apply this technology in chemical, pharmaceutical, paper-making, sewage treatment, seawater desalination and other industries.
This MVR evaporation starts and heats by steam or electric heating device; it is of automatic control by PLC; it can start and stop at any time with high automation degree.
