Sodium chloride wastewater forced circulation multi-effect MVR
evaporator
Introduction
Mechanical vapor recompression (MVR) evaporator uses two steam
generated in the evaporator, the compressor, pressure, temperature,
enthalpy increase, and then sent to the heating chamber of the
evaporator as heating steam, feed liquid to maintain the boiling
state, and heating steam is condensed into water. In this way, the
original steam abandoned has been fully utilized, the latent heat
recovery, and improve the thermal efficiency and economy of steam
is equivalent to 30 effect evaporation, reducing the external
heating and cooling resource demand, reduce energy consumption,
reduce pollution.
Usage
Mechanical vapor recompression (MVR) evaporator, suitable for low
temperature concentration in milk, glucose, organic acid, VC,
xylose, pharmaceutical, chemical, biological engineering,
environmental engineering, waste recycling, papermaking, salt and
other industries.
Main Characteristic
1. MVR energy-saving evaporator technology is currently the most
advanced technology of the evaporator, only need a very small
amount of steam (start-up small steam, in normal operation, almost
no need for steam), greatly reduces the enterprise operation cost,
reduce the pollution of the environment.
2.due to the use of the compressor to provide heat sources,
compared with the traditional evaporator, the temperature
difference is much smaller, can achieve moderate evaporation,
greatly improve product quality and reduce fouling.
3. Without the condenser or only a small area of condenser, the
structure and process are very simple, fully automatic operation,
continuous operation, safe and reliable.
4. equipped with CIP cleaning pipeline, can be achieved on-site
cleaning, the whole set of equipment is easy to operate, no dead
angle.
5. the evaporator is the material at low temperature (evaporation
temperature 35 degrees -100 degrees Celsius), and no foam in the
state of evaporation, uniform liquid, no running material, not easy
to coke, material heating denaturation minimum.
6. the traditional multi effect evaporator using fresh steam as an
energy source, such as the five effect evaporator 1 tons of water
consumption of 0.23 tons of fresh steam; MVR mechanical compression
evaporator the energy consumption of electricity, 1 tons of water
evaporation power consumption of 15-27, the general elevation
smaller material can reach below 20 tons of water consumption.
Energy saving and the degree of local fresh steam price and price
are closely related, such as steam price 180 yuan / ton, price 0.7
yuan per kilowatt and five evaporator evaporation ratio, per a ton
of energy consumption savings of 0.23*180-20*0.7=27.4 yuan, such as
evaporation is 100 tons, the annual operating time is 330 days, 24
hours a day, saving the energy cost is 27.4*100*24*330=21700800
yuan per year. The MVR evaporator saves more than 60% energy than
the five effect evaporator.
7.MVR mechanical compression evaporator price is multi effect
evaporator 2 times, up and down, for new projects, compare
investment differences, investment, purchase MVR more investment,
generally in 300 operating days can be recovered. For the energy
saving transformation project of replacing the original multi
effect evaporator with MVR mechanical compression evaporator, the
transformation investment can be recovered within 500 working days.
