How effective is the MVR evaporator in treating high salt wastewater? The secondary steam from the evaporator is compressed by the compressor, the pressure and temperature increase, and the enthalpy increases. It is then sent to the heating chamber of the evaporator to be used as heating steam, so that the material liquid keeps boiling, while the heated steam itself condenses into water. In this way, the waste steam has been fully utilized, latent heat has been recovered, and the thermal efficiency has been improved. The economy of steam generation is equivalent to 30 efficiency of multi-effect evaporation. Commonly known as MVR evaporator, also known as heat pump mvr.
The evaporation equipment is compact, occupies small area and needs small space. The cooling system can also be omitted. For the existing factories that need to expand evaporation equipment and supply steam, lack of water supply capacity and inadequate site, especially in the case of cryogenic evaporation requiring refrigerated water condensation, investment can be saved and better energy-saving effect can be achieved.
Because of the latent heat of vaporization of secondary steam, the energy consumption of evaporating a ton of water is only 30 kw. As a result of low temperature evaporation, 30 degrees can be evaporated, low temperature evaporation, COD content can be reduced to an order of magnitude.
Of course, the comprehensive treatment of saline wastewater also needs a comprehensive approach to deal with, from the energy consumption of evaporation, 30 kW evaporation to a ton of water is an inexpensive choice.
