MVR Evaporator

1. Summary
MVR evaporator is a kind of energy-saving evaporation equipment, mainly used in pharmaceutical, chemical industry, food, environmental protection and other industries. It uses low temperature and low pressure steam technology and clean energy to produce steam, thus effectively separating the water from the medium. As an international advanced evaporation technology, MVR evaporator is an upgrade product of traditional evaporator, which has significant energy saving effect and environmental protection advantages.

2. Characteristic
High efficiency and energy saving: MVR evaporator adopts the unique mechanical steam recompression (MVR) technology to compress the secondary steam produced in the evaporation process, improve its temperature and pressure, and then use it as a heat source, so as to realize energy recycling. Compared with conventional evaporators, MVR can save about 45% of the evaporator steam consumption.
Environmental protection and emission reduction: the MVR evaporator does not need to use raw steam during operation, reducing the thermal pollution and carbon emissions to the environment. At the same time, its low-temperature evaporation technology also reduces the corrosion of the equipment material, and extends the service life of the equipment.
High degree of automation: The MVR evaporator is equipped with an advanced control system, which can realize the automatic operation and remote control of the equipment, reducing the operation difficulty and labor cost.
Wide range of application: MVR evaporator is suitable for a variety of concentration, viscosity and heat sensitivity of the material evaporation, widely used in pharmaceutical, chemical, food, environmental protection and other industries.

3. Operational Principle
MVR evaporator is a single evaporator, a set of multi-effect lowering film evaporator in one. According to the different concentration of the required product, the segmented evaporation is adopted. When the product cannot reach the desired concentration after the first active body, the product can be pumped again to the upper part of the active body through the vacuum pump under the active body for cyclic evaporation. The effect body inside is a thin tube, the pipe inside is a product, and the outside is steam. During the flow of products from top to bottom, the product flows like a membrane due to the increasing area in the tube to increase the heating area. Through the vacuum pump, reduce the boiling point of water in the product, so as to achieve the concentration effect.

4. Technical Parameter
Evaporation temperature: 40℃ -100℃, which can be adjusted according to the material characteristics.
Power consumption per ton of water: 25KW-100KW, depending on the equipment model and process conditions.
Fresh steam consumption: less, to achieve the efficient use of energy.
Solid content: can be directly evaporated to crystallization to meet the production needs of high concentration products.

5. Sum Up
MVR evaporator has been widely used in many industries for its high efficiency and energy saving, environmental protection and emission reduction, high degree of automation and wide range of application. By adopting the advanced mechanical steam recompression technology and intelligent control system, MVR evaporator not only improves the production efficiency and product quality, but also reduces the operating cost and environmental protection pressure of the enterprise.
