Description
Mechanical vaporization re-compression system, which is called MVR whose principle is to compress the second steam generated by evaporator by high efficiency steam compressor; this process transfers electric energy to heating energy and higher the pressure and temperature of second steam. The second steam with higher temperature will be sent to evaporation room to heat the product for evaporation. So the latent heat of vaporization of the second steam can be circularly used. Making use of less energy which is the mechanical energy of compressor blade wheel as the compression heat pump, energy is added into the heating medium and is circularly used in heating process. Under this circumstance, no need to add first steam as heating medium.
This kind of evaporation system will use electricity to do the evaporate operation. Based on the difference of material
characters, the energy cost by the compression will be different.
Application:
"zero release" solution for industrial waste water
1) Ammonia and chloride waster water, multiple inorganic salt waster water
2) electroplating waste water
3) printing and dyeing waste water
4) food industry waste water
5) paper waste water
6) petrochemical, metallurgy waste water
Evaporation and concentration for process industry
1) food fermentation (aginomoto, citric acid, starch and sugar)
2) pharmacy (traditional Chinesemedicine preparation, low temperature concentration of western medicine)
3) fine chemical (pesticide, synthetic dyes, organic pigments, paints, spice and essence, cosmetic)
4) chlorine chemical (salt water concentration)
5) seawater desalt
6) metallurgical in
