Problems solved by technology
[0005] At present, the traditional Chinese medicine is usually concentrated by thermal steam recompression process. In the process of concentration, it is necessary to use an ejector to inject raw steam to the organic solvent in the traditional Chinese medicine, but this will reduce the concentration and quality of the organic solvent, which is not conducive to Recovery and reuse of organic solvents

The invention discloses a heat pump evaporation and concentration system to improve the recycling rate of an organic solvent and the energy utilization rate of the system. The heat pump evaporation and concentration system is used for evaporating and concentrating the organic solvent-containing raw material liquid, the heat pump evaporation and concentration system comprises an organic solvent water vapor generation system and an organic solvent-containing raw material liquid concentration system, and the organic solvent water vapor generation system comprises a first heat exchanger, and a rawvapor pipeline and a raw material liquid input pipeline which are communicated with the first heat exchanger; the organic solvent-containing raw material liquid concentration system comprises a steamejector, a second heat exchanger and an evaporator which are sequentially communicated, wherein the first heat exchanger is communicated with the steam ejector through a primary steam pipeline; the steam ejector is communicated with the second heat exchanger through a steam ejection pipeline; the second heat exchanger is communicated with an organic solvent extraction pipeline, and the second heat exchanger is communicated with the evaporator through a vapor-liquid mixing pipeline and a liquid pipeline; and the evaporator is communicated with the steam ejector through a secondary steam pipeline.
Description
technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a heat pump evaporation concentration system. Background technique [0002] Evaporation and concentration is a very typical chemical unit operation in industrial production, and is widely used in industrial production processes such as chemical industry, light industry, food, pharmaceuticals, seawater desalination and sewage treatment. [0003] The material that is often evaporated in industrial production is aqueous solution. Moreover, saturated steam is often used as a heating source, and the "secondary steam" evaporated from the solution is basically not up to the gas conditions due to its low pressure, low quality and unfavorable transportation. Therefore, this part of the secondary steam is directly discharged to the atmosphere, or condensed by the cooling system or used in some low-pressure steam equipment, causing pollution and energy waste. [0004] At pre...
