摘要 基于增湿去湿原理,设计了1种新型的含盐废水处理系统,这套系统包括热源、填料塔、翅片管换热器以及水泵等部件,介绍了各部件的工作原理和结构大小,同时研究了影响系统性能特征的各种因素。结果表明,各因素影响程度依次为填料塔顶部含废水进口温度、填料塔底部通入空气量、通入系统的含盐废水流量、上下2级冷凝室的进口空气流量比。在填料塔顶部含废水进口温度75℃、填料塔底部通入空气体积流量35 m^3/h、通入系统的含盐废水体积流量140 L/h、上下2级冷凝室的空气进口流量比为2:1的优化条件下,冷凝水产量和系统效率分别为3.58 kg/h和40.88%。 A new type of brine wastewater treatment system has been designed based on the principle of humidification-dehumidification. This system included heat source, packed column, finned tube heat ex-changer, water pump and other accessories. The working principle, structure and size of each part, and effect of various factors on system performance were researched. The results showed that, the influencing extent of various factors was inlet temperature of brine wastewater at top part of the packing tower, the air volume at the bottom of the packing tower, the flow rate of brine wastewater into the system, the inlet air flow ratio of upper and lower second level condensing chambers. When inlet temperature of brine wastewater at top part of the packing tower, the air volume at the bottom of the packing tower, the flow rate of brine wastewater into the system, the inlet air flow ratio of upper and lower second level condensing chambers was 75 ℃, 35 m~3/h, 140 L/h and 2:1 respectively, condensate water production and system efficiency was3.58 kg/h and 40.88% respectively.
