MVR Multi-effect Evaporator

MVR Multi-effect Evaporator

MVR Evaporator Overview
MVR Evaporator (Mechanical Vapor Recompression), a novel evaporator that reuses secondary steam after compression. It can evaporate materials by simply heating them to the evaporation temperature with the system running, requiring minimal external energy during normal operation, representing a new energy-saving technology in the evaporation concentration field. As early as the 1960s, Germany and France began applying this technology to industries such as chemicals, pharmaceuticals, papermaking, wastewater treatment, and seawater desalination.
       This MVR evaporator is initiated and heated using steam or electric heating equipment; PLC automatic control; can be started or stopped at any time, with a high degree of automation.
       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. 

Advantages and Characteristics of MVR Evaporator
       1. Energy-saving: Utilizes secondary steam preheating for heating, with no waste heat steam emitted, equivalent to the efficiency of an 8-effect 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-friendly: The equipment only requires preheating steam initially, then no additional heat source is needed. The variable frequency motor directly drives the compressor for mechanical compression evaporation.
       2. environmental protection: equipment only need to preheat steam, then no heat, direct inverter motor can drive the compressor can be compressed compressor.
       3. High Automation Level: MVR Evaporator with full automatic control system, the entire evaporator unit requires only one person to operate from the central control room, reducing labor costs and improving product quality.
       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. Compressor Selection: For evaporation rates of 0.2~2T, a low-speed screw compressor is generally used; for evaporation rates above 2T, a high-speed centrifugal compressor is recommended.
       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 Evaporator Application Industry
1. Industrial Waste Treatment (Environmental Protection Sector)
Concentration of industrial wastewater and water recycling. Applications include electroplating, paint production, pharmaceuticals and pesticides, metal processing, papermaking, and crude oil production industries. Treatment of wastewater to remove organic matter and inorganic salts. Turning waste into treasure. How to solve the problem of low-cost reuse of high-salinity industrial wastewater, a well-known challenge, is a key issue. MVR evaporators are an excellent solution for treating such industrial wastewater.
2. Chemical Industry
The treatment of process water for the production of hollow fiber molecules, purification of spices, manufacturing of chemicals like sodium persulfate, desalination of seawater, concentration and crystallization of organic additives, refining of extracts, and analysis of reaction by-products into solvents and products.
3. Pharmaceutical Industry
Our pharmaceutical industry, a traditional sector, relies heavily on outdated, old-style evaporators, which not only degrade the quality of medicines but also squander vast amounts of energy, urgently requiring an upgrade to reduce CO2 emissions. MVR is also used in the evaporation, concentration, crystallization, and drying of Western medicine, as well as the concentration of traditional Chinese medicine.
4. Food Industry
In the deep processing of the food industry, evaporation technology is extensively used for dehydration purposes, such as concentrating corn syrup and extracting amino acids. This includes the concentration of isopropanol extracted from pectin, extraction and concentration of fragrances, distillation sediment of food and fermented spices, and the refining of solvents.
5. Winemaking Industry
The wine-making industry is a time-honored profession in our country. MVR evaporators can replace outdated distillation equipment.
6. Dairy Industry
Due to the need for low temperatures, high cleanliness, and high automation in the dairy industry, which traditional evaporators struggle to meet, this has created a great opportunity for the vigorous development of MVR evaporators.
7. Beverage Industry Concentrates
Tomato Sauce, Peach Puree, Apricot Puree, Carrot Puree, Apple Puree, Kiwi Puree
       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.
