Normal Temperature Vacuum Evaporator
The boiling point of the liquid decreases as the pressure in the evaporator decreases. The boiling point temperature changes with the external pressure. The empirical relationship between the boiling point T (K) and the pressure P (Pa) is Log(P1/P2)=L/(2.303R)(1/T2-1/T1) Under the action of the vacuum system, the vacuum degree in the low-temperature evaporator reactor is about 6.2744KPa->37℃, and the evaporation temperature of water under normal atmospheric pressure is 101.325KPa->100℃. The pressure when the evaporation temperature is 0℃ is 0.6105KPa->0℃. The boiling point of water at this pressure is 6.2774KPa is 37℃.
Heating and cooling during the evaporation process, heat exchange is realized by the work done by the compressor on Freon (refrigerant). The liquid is heated and boils to evaporate into water vapor, and the water vapor is liquefied into distilled water when cooled.
After the high-salt waste liquid (solution) loses its water (solvent) through evaporation, the metal salt (solute) in the solution precipitates into crystals.

1. Fully automatic operation, remote wireless monitoring by mobile device terminals, truly unattended2. Solve the impact of ambient temperature on the low-temperature evaporation system and ensure the normal operation of the equipment in high-temperature environments3. Distribute liquid through atomization to achieve maximum evaporation efficiency and reduce energy consumption4. Independent water ring vacuum system, reaching the liquid filling state in 3 minutes, with intermittent automatic start and stop function5. Avoid or reduce the problem of internal scaling of the equipment after long-term use and increase the service life of the equipment.6. Ensure that the remaining liquid will not freeze inside the equipment and protect the equipment and pipelines.7. Continuous evaporation mode, replenishing liquid while evaporating, automatically discharging after reaching concentration, no need for system venting and shutdown.8. The system only requires industrial power supply for operation, and the equipment valves are all electric valves, making the operation stable and reliable.
