摘要:
加湿除湿淡化工艺是一种利用低位热能实现浓盐水淡化的水处理技术。该技术提高了设备热回收利用率，通过将加湿箱与除湿箱分离，使浓盐水和淡水部分严格分开，浓盐水可以限制在很小的区域，其他区域可以用非昂贵材料制造，降低了设备成本。介绍了浓盐水加湿除湿淡化技术原理、结构组成及开发研究历程进展，分析了影响浓盐水淡化效率的主要因素及相关改进研究，阐明了该工艺的技术特点，探讨了加湿除湿淡化技术亟待解决的技术问题。研究认为，以太阳能为热源的加湿除湿技术适用于浓盐水储量较大且太阳能丰沛的干旱半干旱地区，是解决民生饮水增量问题的有效措施。
Abstract:
Humidification and dehumidification desalination process is a kind of water treatment technology which uses low-level heat energy to realize brackish water desalination. This technology improves the heat recovery and utilization rate of the equipment. The equipment can separate the humidification box from the dehumidification box, so that the seawater and fresh water can be strictly separated. The brackish water can be limited in a small area, and other structure can be made of economic materials, thus reducing the equipment cost. In this paper, the principle, structure and research progress of brackish water humidification and dehumidification desalination technology are introduced. The main factors affecting the efficiency of brackish water desalination and related improvement were analyzed. The technical characteristics of the process were summarized in details, and the technical problems to be solved in humidification and dehumidification desalination technology were discussed. It is considered that the humidification and dehumidification technology with solar energy as the heat source is suitable for the arid and semi-arid areas with large reserves of brackish water and abundant solar energy, which is an effective measure to solve the problem of increasing drinking water for people’s livelihood.
