MVR蒸发器概述/MVR evaporator overview
MVR蒸发器（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蒸发器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.
MVR蒸发器的优势及特点/Advantages and Characteristics of MVR Evaporator
1、节-能：利用二次蒸汽预热加热，没有废热蒸汽排放，相当于8效蒸发器的效率。
1, energy saving: the use of secondary steam preheating heating, no waste heat steam emissions, the equivalent of 8 efficiency evaporator efficiency.
2、环-保：设备只需要预热蒸汽，之后就无需热源，直接变频电机带动压缩机就可以机械压缩式蒸发器。
2, environmental protection: equipment only need to preheat steam, then no heat, direct inverter motor can drive the compressor can be compressed compressor.
3、自动化程度高：MVR蒸发器全自动控制系统，整套蒸发器只需在中控室一人操作即可，降低了人力成本，提高了产品质量。
3, a high degree of automation: MVR evaporator automatic control system, the entire evaporator only in the control room can operate a person, reducing labor costs and improve product quality.
4、压缩机选型：蒸发量0.2~2T一般选用低速罗茨压缩机，2T以上选用高速离心式压缩机。
4, the compressor selection: evaporation of 0.2 ~ 2T general selection of low-speed Roots compressor, 2T above the choice of high-speed centrifugal compressor.
MVR蒸发器应用行业/MVR evaporator application industry
1、处理工业废水（环保领域）
工业废水的浓缩和水的循环再利用。如电镀行业、涂料生产行业、医药和农药行业、金属加工行业、造纸行业和原油生产行业等污水处理。从污水中去掉有机物和无机盐。变废为宝。如何低成本解决高含盐工业废水回用问题，是众所知难题，MVR蒸发器是处理这类工业废水的好方案。
2、化工工业
生产空心纤维分子的工艺用水的处理、香料的提纯、亚氯酸钠和过硫酸钠等化工原料的生产、海水的淡化、有机添加剂的浓缩和结晶、提取液的精炼、把反应生成物分析成溶剂和产品。
3、制药工业
我国的制药行业，是个传统的行业，使用了大量的老化、旧式蒸发器，不仅降低药品质量，还浪费了大量的能源，急需升级换代减少二氧化碳的排放。MVR还用于生产西药的蒸发、浓缩、结晶和干燥，中药的浓缩。
4、食品行业
在食品深加工行业，大量采用蒸发技术实现脱水的功能。如浓缩玉米浆和提取葡萄糖、氨基酸等。从果胶中提取的异丙醇的浓缩、芳香物的提取和浓缩、食品与发酵香料的分馏沉淀物、溶剂的精炼。
5、制酒工业
制酒行业我国是个古老的行业。MVR蒸发器可以代替陈旧的蒸馏用的设备。
6、牛奶行业
因为牛奶行业需要的低温、高度清洁、高度自动化等特点决定了传统的蒸发器难达到这些要求，所以才有MVR蒸发器的大力发展的机遇。
7、饮料工业的浓缩
番茄酱、桃浆、杏浆、胡萝卜浆、苹果浆、猕猴桃浆
1, treatment of industrial wastewater (environmental protection)
Concentration of industrial wastewater and recycling of water. Such as electroplating industry, paint production industry, pharmaceutical and pesticide industry, metal processing industry, paper industry and crude oil production industry and other sewage treatment. Remove organic and inorganic salts from the effluent. Turning waste into treasure. How to solve the problem of high-salt industrial wastewater reuse is a well-known problem. MVR evaporator is the best solution to deal with such industrial wastewater.
2, chemical industry
Production of hollow fiber molecules, treatment of water, purification of spices, production of chemical raw materials such as sodium chlorite and sodium persulfate, desalination of seawater, concentration and crystallization of organic additives, refining of the extract, and analysis of the reaction product into Solvents and products.
3, the pharmaceutical industry
China's pharmaceutical industry, is a traditional industry, the use of a large number of aging, old evaporator, not only reduce the quality of drugs, but also a lot of waste of energy, the urgent need to upgrade to reduce carbon dioxide emissions. MVR is also used to produce western medicine for the evaporation, concentration, crystallization and drying of Chinese medicine.
4, the food industry
In the deep processing of food industry, a large number of evaporation technology to achieve the function of dehydration. Such as concentrated corn steep liquor and extraction of glucose, amino acids and so on. Extraction of isopropanol from pectin, extraction and concentration of aromatics, fractionation of food and fermented fragrances, refining of solvents.
5, wine industry
Wine industry China is an ancient industry. MVR evaporator can replace the old distillation equipment.
6, the milk industry
Because the milk industry needs low temperature, high degree of cleanliness, high degree of automation and other characteristics of the traditional evaporator is difficult to meet these requirements, so have the MVR evaporator development opportunities.
