阅读说明：本技术 串联式电镀废水热泵膜蒸发系统及方法 (Tandem type electroplating wastewater heat pump membrane evaporation system and method ) 是由 岳晨 彭有德 高鹏举 徐阳 于 2021-08-31 设计创作，主要内容包括：本发明公开了一种串联式电镀废水热泵膜蒸发系统及方法,属于节能环保领域。其特征在于：该系统的热泵侧冷冻水(26)以并联方式通过n级冷凝器,可保证通过膜蒸发器的渗透侧冷冻水维持较低温度；电镀废水料液以串联方式,依次通过n级膜蒸发器,可以使进入每一级膜蒸发器的料液维持较高的温度,保持高的传质驱动力。相比于常规热泵耦合膜蒸发系统,该系统可以借助多级膜蒸发器大幅度提升浓度,实现降温结晶资源化回收。此外,该系统还可以根据料液浓度提升要求,灵活的进行级数选择。由于该系统与热泵构成闭式循环,因此整体的节能性能也显著提升,并且通过多级膜蒸发器获得的冷冻水(26)也可再次进行循环使用,实现了电镀废水的“零排放”。(The invention discloses a tandem type electroplating waste water heat pump film evaporation system and method, and belongs to the field of energy conservation and environmental protection. The method is characterized in that: the chilled water (26) on the heat pump side of the system passes in parallel n The stage condenser can ensure that the chilled water passing through the permeation side of the film evaporator maintains a lower temperature; the electroplating wastewater feed liquid passes through in series n The stage film evaporator can maintain the feed liquid entering each stage of film evaporator at a higher temperature and maintain a high mass transfer driving force. Compared with a conventional heat pump coupling film evaporation system, the system can greatly increase the concentration by means of a multistage film evaporator, and realize the resource recovery of cooling crystallization. In addition, the system can also improve the requirement according to the concentration of the feed liquidThe selection of the number of stages can be carried out. Because the system and the heat pump form closed circulation, the integral energy-saving performance is also obviously improved, and the chilled water (26) obtained by the multistage film evaporator can be recycled, thereby realizing 'zero emission' of electroplating wastewater.)
