The Research and Development of Mechanical Vapor Recompression Evaporation Energy-Saving System

In order to solve the problem of high energy consumption for evaporators, the energy-saving evaporation technology of Mechanical Vapor Recompression (MVR) was purposed in this paper. The enthalpy of the thermal steam compressed by the compressor was increased, and the vapor was used to heat the raw material of the evaporator. The fresh steam is saved and the energy consumption was reduced too. And the energy-saving system of mechanical vapor compression evaporation was researched and developed. It is mainly composed of fluid tanks, preheaters, evaporator, separator, vapor compressor and on-line monitoring and controlled system. In addition, the operating costs were compared between MVR system and the traditional there-efficient evaporator. The results show that the economic benefit of MVR system is more remarkable than traditional there-efficient evaporation.
