The heat pump flash evaporation evaporative concentration system comprises a material inlet pipeline, a waste water circulation pipeline, a heating separator, a discharge pipeline, a distilled water condensation system, a distilled water cooling system, and a heat pump refrigerant circulation system; a circulation pipeline is composed of the heating separator and the waste water circulation pipeline; an outlet of the waste water circulation pipeline is provided with the discharge pipeline; the material inlet pipeline is arranged at the middle part of the heating separator; the heat pump refrigerant circulation system is arranged between the heating separator and the waste water circulation pipeline; andthe heating separator is communicated with the distilled water cooling system through the distilled water condensation system.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a heat pump flash evaporation concentration system. Background technique [0002] The problems of energy technology and environmental pollution have become increasingly prominent in daily production. Sewage is produced in the production process of various industries, and these polluted water contain various pollutants, which can no longer be directly discharged into the natural environment. All kinds of materials, biology, chemistry, etc. can only be discharged after the treatment reaches the standard. The oily wastewater, salty wastewater, and difficult-to-treat mother liquor generated during the treatment process will be reduced and concentrated by evaporation. The traditional multi-effect evaporation system needs to use a large amount of steam as a heat source to evaporate and concentrate: [0003] 1. In the actual process, there are a large number of sma...
