Description
Product DescriptionMVR is the abbreviation of mechanical vapor recompression.
The working process of MVR is to compress the low temperature steam through the compressor, increase the temperature and pressure, increase the heat enthalpy, and then enter the heat exchanger to condense to make full use of the latent heat of steam. In addition to starting of the operation, there is no need to use new steam for heating. The secondary VAPOR is compressed by the compressor, the pressure and temperature are raised, the heat is increased, and then sent to the heating chamber of the evaporator as a heating steam to keep the liquid boiling, and the heating steam itself is condensed into water. In this way, the steam that was originally planned to be discarded turns to be fully utilized, the latent heat is recovered, and the thermal efficiency is improved. The economy of the steam generation is equivalent to the 30 effect of multi-effect evaporation. In order to make the evaporation device as simple as possible and easy to operate, a centrifugal compressor or a Roots type compressor can be used. These machines have a high volumetric flow rate in the range of 1:1.2 to 1:2 compression ratio. The evaporation equipment has a small footprint and a small space required. The cooling system can be omitted.
Advantages and Characteristics of MVR Evaporator1, Energy Saving: the use of secondary Vapor preheating, no Heat Waste, Working Efficiency is equivalent of 8 effect evaporator.
2, Environmental Friendly: Equipment only needs Preheat Steam which brings high economics.
3, High Automatic Control: Equipped withevaporator automatic control system, the whole system only needs one person working in Control Room for Full Control Coverage, reducing Labor Costs and Operation Errors.
4, The Compressor Selection: Evaporator will be designed with suitable Steam Compressor mainly from the Roots Compressor and Centrifugal Compressor, in compliance with the Capacity of the MVR System.
