Description
MVR evaporator is an MVR evaporator coupling technology composed of
falling film evaporator. Its main components: steam compressor,
heater exchanger, separator, preheating system, automatic control
system and etc..
The falling film evaporator specified with film, the liquid be sent
from the top to the end in the heater through the pump, to let the
material liquid evenly distributed in each heat exchanger of the
inner surface, and keep the heat exchanger tube surface wet to
achieve a higher heat transfer coefficient of the evaporator. The
material liquid is film flow, so this evaporator has the advantages
of high heat transfer coefficient, low energy consumption, low
pressure drop, the residence time is short.
Distributor design: to consider the liquid viscosity, density,
surface tension, combined with the heater parameter, and to ensure
the minimum design of falling liquid density. Falling film
evaporator distributor is critical, if the performance defects will
appear uneven film,dry cloth tube, coking, evaporation intensity
insufficient.
Heater selection:plate heat exchanger or tubular heat exchanger
MVR falling film Evaportor Application: food, fermentation,
pharmaceutical industry,feed concentration, salt concentration, the
concentration of heat sensitive materials.
Feature characteristics:
1.Energy saving: The secondary vapor produced by evaporation can be
used as heat steam at next effect
2.High automatic: Applying PLC automatic control system, automatic
control feed time and discharge time, CIP automatic cleaning,
automatic generation of operation data, automatic alarm
3.High manufacture standard, high quality parts ,stable to run.
4.The liquid flow down as film, short residence time, evenly
heated, suitable for temperature sensitive or foaming material
The
liquid to be concentrated is supplied to the top of the heating
tubes and distributed evenly into the heat tubes through liquid
distributor, and under the force of gravity and air flow, the
liquid flow down from top in the form of liquid
film.
