Roots compressor MVR system solution
Introduction of MVR principle
The mechanical vapor recompression evaporator, or MVR for short, is based on the principle that the secondary steam generated by the high-efficiency steam compressor compresses the evaporator, converts electrical energy into heat energy, and raises the pressure and temperature of the secondary steam. The steam is driven into the evaporation chamber to heat the material to evaporate, so as to achieve the purpose of recycling the latent heat of vaporization of the secondary steam. By using relatively little energy, ie the mechanical energy of the compressor wheel in the case of a compression heat pump, the energy is added to the process heating medium and enters a continuous cycle. In this case, no primary steam is required as a heating medium.
This compressor is suitable for the purification of organic working fluids, seawater desalination, vapor compression and transportation, concentra- tion and crystallization in the chemical, pharmaceutical, metallurgical, food industries and the secondary vapor recompression process of the MVR system for industrial waste liquid treatment.
Brief introduction of compressor structure
The compressor consists of a main and driven rotor group, a shell, a me- chanical seal, a bearing, a synchronous gear and a coupling: O Compressor rotor group: The compressor rotor group is composed of the main shaft and the fan blade assembly. The main shaft is made of high-strength alloy Steel; the fan blades are two blades, using advanced arc-involute profiles, and have passed the rotor dynamics calculations.
