90T/H Sodium Chloride MVR+ Three-Effect Evaporation Crystallization
Project
The mechanical vapor recompression (MVR) evaporator uses two steam
sources: the evaporator and the compressor. This creates heating
steam, which is then sent to the evaporator's heating chamber where
it condenses into water after increasing in temperature, pressure,
and enthalpy. In this manner, the original steam that was abandoned
has been fully utilized, the latent heat recovery has improved the
thermal efficiency and economy of steam, comparable to 30 effect
evaporation, lowering the demand for external heating and cooling
resources,lowering energy consumption, and lowering pollution.

Features
1. Low energy consumption and operating cost;
2. Small floor space;
3. Less supporting facilities for public works, less total project
investment,
4. Stable operation and high degree of automation;
5. No primary steam is required;
6. Because of the common single effect, the product stays for a
short time
7. Simple process, strong practicality and excellent operation
characteristics under partial load
8. Low operating cost, evaporating below 40℃ without refrigeration
equipment, especially suitable for heat-sensitive materials.
Working principle
The working process is that the steam at low temperature is
compressed by the compressor, the temperature and pressure are
increased, the enthalpy is increased, and then the steam is
condensed into the heat exchanger to make full use of the latent
heat of the steam. No steam is generated during the entire
evaporation process except for starting the engine.
In the process of multi-effect evaporation, the secondary steam of
a certain effect of the evaporator can not be used as the primary
effect heat source directly, but only as the secondary effect or
secondary effect heat source. For example, as an effective heat
source, it must be given extra energy to raise its temperature
(pressure). The steam jet pump compresses only part of the
secondary steam, while the MVR evaporator compresses all of the
secondary steam in the evaporator.
Advantages:
Finished has high purity, shiny appearance, free liquidity and
stable iodine content.
Low loss, the loss of NaCl is under 8%.
