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。
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, energy saving: the use of secondary steam preheating heating, no waste heat steam emissions, the equivalent of 8 efficiency evaporator efficiency.
2, environmental protection: equipment only need to preheat steam, then no heat, direct inverter motor can drive the compressor can be compressed compressor.
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, 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, 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.
7, the concentration of the beverage industry
Tomato sauce, peach pulp, apricot pulp, carrot pulp, apple pulp, kiwi pulp
