Abstract In order to solve the problem of energy saving of MVR and energy waste in MEE in the field of low vacuum and low temperature evaporation, a heat pump system and a double effect evaporation concentration system are combined to propose a high temperature heat pump double effect evaporation concentration system. It replaces the high-temperature steam heat source and makes full use of the heat of the last-effect secondary steam, and at the same time realizes the recycling of the intermediate water. In this paper, an industrial experimental platform is designed and built. The experimental results showed: the total evaporation of this system can reach 1985 kg/h, the heat pump COP is 4.92, the unit power consumption evaporation is 11.86 kg/(kW·h). Besides, the thermal characteristics and influencing factors of high-efficiency heat pump double-effect evaporation system are studied, which provides experimental basis and guidance for the practical engineering application, efficient design and optimization of such systems.
