  • the temperature of the secondary vapor generated during evaporation is always lower than the liquid temperature due to the rising boiling point, which creates technical difficulties for the energy-saving utilization of the secondary vapor.
  • the multi-effect evaporator uses the latent heat of vaporization of externally supplied vapor for many times. However, whatever happens, the externally supplied vapor enters and flows out of the system in a steam state so that the enthalpy difference of the steam entering and leaving the system is very small. For example, after the saturated steam (1.0MPa(G), 185°C) enters the evaporation system for multi-effect evaporation, it will become 45° C secondary steam and then be discharged from the system, with the enthalpy difference less than 250kJ/kg and the heat utilization rate of the externally supplied vapor less than 9%. Not only that, a large amount of circulating water will be used to condense the secondary steam with the purpose of ensuring the vacuum degree during evaporation. The circulating water consumption as well as other energy consumption decreases the heat utilization rate of second law of thermodynamics.

Its working process is to compress the steam (secondary steam) at low temperature through a compressor, increase the temperature, pressure and the enthalpy, and then condensate steam in an evaporator to make full use of the latent heat of steam. Except for start-up, the externally supplied steam is not used in the whole evaporation process, so as to fully utilize the secondary steam, recover latent heat and improve thermal efficiency, thus the economy is equal to 20-effect evaporation. However, one-time investment of MVR is greater than that of multi-effect evaporation, which is generally 1.5 times more than multi-effect evaporation.
