Customized Pillow plate heat transfer equipment for Mechanical vapor compression(MVR)
MVR Description
Mechanical vaporization re-compression system, which is called MVR which principle is to compress the second steam generated by evaporator by high efficiency steam compressor; this process transfers electric energy to heating energy and higher the pressure and temperature of second steam. The second steam with higher temperature will be sent to evaporation room to heat the product for evaporation. So the latent heat of vaporization of the second steam can be circularly used. Making use of less energy which is the mechanical energy of compressor blade wheel as the compression heat pump, energy is added into the heating medium and is circularly used in heating process. Under this circumstance, no need to add first steam as heating medium.
MVR evaporator components:
Evaporator:
The liquid material inside the evaporator heated by steam for evaporation. Choose different type evaporator according to different liquid material features.
Separator(crystallizer):
use to separate vapor and liquid, according to different liquid features choose different type separator(crystallizer), such as normal separator, gravity separator, special design separator (crystallizer ).
Vacuum system:
Use to keep the whole system vacuum degree, pump some air, fixed gas, liquid entrainment of gas from the evaporator, so as to obtain the whole system stable evaporation process.
Pump:
Use to transfer liquid and concentrated liquid. According to different liquid features choose different pumps, such as centrifugal pump, displacement pump,screw pump.
Compressor:
Use to compress secondary vapor to supply heating source, improve secondary vapor enthalpy. According to different flow and compression ratio choose different compressor, in the case of pressure rise increase, multistage compressor can be used in series.
Control system:
MVR Evaporation system control center, by regular motor speed, control valve,flow meter, temperature and pressure, to realize automatic evaporation, cleaning, stop operations and so on. Automatic alarm, automatic protection system is not damaged, keep dynamic balance.
Cleaning system:
Different liquid after period of evaporator, there maybe scaling phenomenon, general speaking, 99% of the scale can be removed by adding chemical solvent, and can use CIP clean in situ or disassemble to clean.
Scope of application:
Mechanical vapor compression(MVR) evaporator, suitable for milk, glucose, organic acid, VC, xylose, pharmaceutical, chemical and biological engineering, environmental engineering, waste recycling, paper making, salt industry for low temperature concentration.
Best possible energy efficiency
Compared to multiple-effect evaporators, MVR evaporators consume
considerably less energy.
Non-foaming design
Low vapor velocities inside the evaporator, low shear rates, and
the free flow falling film construction are advantages of the
design in minimizing foam creation. This is especially important in
MVR evaporators, not only to maximize the production of clean
condensate, but also for protection of the compressor or fan.
Non-plugging design
Uniform liquor distribution of the liquor over the lamellas, and
the continuous redistribution of the liquor created by the dimpled
shape of the lamella surface, ensure a completely wetted heating
surface and eliminate local scaling or over-concentration of
liquor. The lamella heating surface ensures that water-soluble
scaling can be washed away by a simple dilution wash, eliminating
the need for time-consuming and costly outages for cleaning.
Cleanest condensates
Highly efficient condensate segregation in the evaporator ducts and
lamellas, plus the integrated stripping of foul condensate
fractions, produce clean and re-usable water.
