MVR蒸發(fā)器概述/MVR evaporator overview
MVR蒸發(fā)器（mechanical vapor recompression）的簡稱，蒸發(fā)器產(chǎn)生的二次蒸汽經(jīng)過壓縮后再利用的新型蒸發(fā)器。只需開車啟動將物料加熱到蒸發(fā)溫度即可蒸發(fā)，正常運轉(zhuǎn)時基本無需外界能源，蒸發(fā)濃縮領(lǐng)域中的能耗節(jié)約的新技術(shù)。早在60年代，徳國和法國已經(jīng)開始的將該技術(shù)應(yīng)用于化工、制藥、造紙、污水處理、海水淡化等行業(yè)。
本MVR蒸發(fā)器采用蒸汽或電熱裝置進行啟動加熱；PLC自動控制；隨時開機、停機，自動化程度高。
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蒸發(fā)器的優(yōu)勢及特點/Advantages and Characteristics of MVR Evaporator
1、節(jié)-能：利用二次蒸汽預(yù)熱加熱，沒有廢熱蒸汽排放，相當于8效蒸發(fā)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、環(huán)-保：設(shè)備只需要預(yù)熱蒸汽，之后就無需熱源，直接變頻電機帶動壓縮機就可以機械壓縮式蒸發(fā)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、自動化程度高：MVR蒸發(fā)器全自動控制系統(tǒng)，整套蒸發(fā)器只需在中控室一人操作即可，降低了人力成本，提高了產(chǎn)品質(zhì)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、壓縮機選型：蒸發(fā)量0.2~2T一般選用低速羅茨壓縮機，2T以上選用高速離心式壓縮機。
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蒸發(fā)器應(yīng)用行業(yè)/MVR evaporator application industry
1、處理工業(yè)廢水（環(huán)保領(lǐng)域）
工業(yè)廢水的濃縮和水的循環(huán)再利用。如電鍍行業(yè)、涂料生產(chǎn)行業(yè)、醫(yī)藥和農(nóng)藥行業(yè)、金屬加工行業(yè)、造紙行業(yè)和原油生產(chǎn)行業(yè)等污水處理。從污水中去掉有機物和無機鹽。變廢為寶。如何低成本解決高含鹽工業(yè)廢水回用問題，是眾所知難題，MVR蒸發(fā)器是處理這類工業(yè)廢水的好方案。
2、化工工業(yè)
生產(chǎn)空心纖維分子的工藝用水的處理、香料的提純、亞氯酸鈉和過硫酸鈉等化工原料的生產(chǎn)、海水的淡化、有機添加劑的濃縮和結(jié)晶、提取液的精煉、把反應(yīng)生成物分析成溶劑和產(chǎn)品。
3、制藥工業(yè)
我國的制藥行業(yè)，是個傳統(tǒng)的行業(yè)，使用了大量的老化、舊式蒸發(fā)器，不僅降低藥品質(zhì)量，還浪費了大量的能源，急需升級換代減少二氧化碳的排放。MVR還用于生產(chǎn)西藥的蒸發(fā)、濃縮、結(jié)晶和干燥，中藥的濃縮。
4、食品行業(yè)
在食品深加工行業(yè)，大量采用蒸發(fā)技術(shù)實現(xiàn)脫水的功能。如濃縮玉米漿和提取葡萄糖、氨基酸等。從果膠中提取的異丙醇的濃縮、芳香物的提取和濃縮、食品與發(fā)酵香料的分餾沉淀物、溶劑的精煉。
5、制酒工業(yè)
制酒行業(yè)我國是個古老的行業(yè)。MVR蒸發(fā)器可以代替陳舊的蒸餾用的設(shè)備。
6、牛奶行業(yè)
因為牛奶行業(yè)需要的低溫、高度清潔、高度自動化等特點決定了傳統(tǒng)的蒸發(fā)器難達到這些要求，所以才有MVR蒸發(fā)器的大力發(fā)展的機遇。
7、飲料工業(yè)的濃縮
番茄醬、桃漿、杏漿、胡蘿卜漿、蘋果漿、獼猴桃漿
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.
