    MVR evaporation

    MVR is the English abbreviation for vapor recompression, which is to increase the pressure of the vaporized secondary vapor after recompression (the corresponding temperature is also increased), and use the compressed vapor as the heating medium to drive the evaporation system to fully realize heat energy The recycling utilization of the new technology greatly reduces the energy consumption of the evaporation system.

    From the perspective of the evaporation process, it is divided into two situations: crystallization and no crystallization during the evaporation process

    1. When there is no crystallization in the evaporation process, the system is relatively simple. The system is composed of a preheater, an evaporator (either a rising film type or a falling film type), a separator, an MVR compressor and a receiving tank (as shown in the figure below). Equipped with discharge pump and control part to form a complete set of MVR evaporation system; evaporation can be at normal pressure or negative pressure, depending on the characteristics of the material, negative pressure evaporation should consider the cavitation allowance of the discharge pump to overcome the system vacuum.

    2. For the occasions where crystallization occurs during the evaporation process, the system is slightly more complicated, mainly because the fluidity of the solid after crystallization determines the difficulty of discharging the crystalline salt, especially in the case of negative pressure evaporation, it is the key to solve the solid discharging .

    The composition of the system adds a salt collector, a centrifuge and a forced circulation pump on the basis of the non-crystallization system;

    The operating cost of the MVR evaporation system is mainly electrical energy. Generally, the energy consumption of MVR is 20-30KW/ton of water (different working conditions have different energy consumption).

    As a professional manufacturer of evaporation systems, our company has rich experience in system design and control, realizes energy consumption, adopts automatic control, and basically can realize unmanned operation.
