MVR蒸发器概述/MVR evaporator overview
MVR是蒸汽机械再压缩技术（mechanical vapor recompression ）的简称。
MVR is the abbreviation of mechanical vapor recompression.
MVR its work is the low temperature of the steam by the compressor compression, temperature, pressure increases, increased enthalpy, and then into the heat exchanger condensation, in order to take full advantage of the latent heat of steam. In addition to the start of the car, the entire evaporation process without the need for steam from the evaporator out of the secondary steam, the compressor compression, pressure, temperature increases, the enthalpy increases, and then sent to the evaporator heating chamber as heating steam, So that the feed liquid to maintain the boiling state, while the heating steam itself is condensed into water. So that the original steam to be abandoned to be fully utilized, the recovery of latent heat, improve thermal efficiency, raw steam economy is equivalent to multi-effect evaporation of 30 effect. For the manufacture of the evaporator as simple as possible and easy to operate, a centrifugal compressor, a Roots compressor may be used. These machines have a higher volume flow in the 1: 1.2 to 1: 2 compression ratio range. The compact space for the evaporation equipment is also small. But also save the cooling system. For the need to expand the evaporation equipment for the steam, the site is not enough existing plant water supply capacity, especially low-temperature evaporation needs of frozen water condensation occasions, you can receive both to save investment and achieve better energy efficiency.
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: I designed the 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
In summary, MVR applications are very wide, so that the traditional multi-effect evaporator applications, MVR evaporator can also be replaced. MVR evaporator and traditional evaporator, not only has a great advantage of energy saving and environmental protection, but also reduces operating costs, is the traditional multi-effect evaporator the best upgrading system. With the country's emphasis on environmental protection and energy conservation and emission reduction policies, MVR evaporator will replace the traditional evaporator, for the national environmental protection, energy conservation and sustainable development play a huge role. But also to the enterprise to bring the actual social and economic benefits.
