背景技术Background technique
随着淡水资源的短缺，海水淡化技术日益受到各个国家的重视。海水淡化就是将海水中的盐分和水分分离的过程，最终得到淡水和浓缩盐水。传统的海水淡化方法主要有蒸馏法、反渗透法、电渗析法、冷冻法、水合物法和溶剂萃取法等。目前蒸馏法已经实现工业化生产，但是传统的蒸馏法能耗高，经济效益低且存在海水淡化装置结构复杂，操作运行困难，海水腐蚀较大和换热效率低等问题。反渗透法以其设备结构简单，易于维护等优点已经逐渐取代蒸馏法成为目前海水淡化市场最广泛应用的技术。With the shortage of fresh water resources, seawater desalination technology has been paid more and more attention by various countries. Desalination of seawater is the process of separating the salt and water in seawater to obtain fresh water and concentrated brine. Traditional seawater desalination methods mainly include distillation, reverse osmosis, electrodialysis, freezing, hydrate and solvent extraction. At present, the distillation method has achieved industrial production, but the traditional distillation method has high energy consumption, low economic benefits, complex structure of seawater desalination equipment, difficult operation, large seawater corrosion and low heat transfer efficiency. Reverse osmosis has gradually replaced distillation as the most widely used technology in the seawater desalination market due to its simple equipment structure and easy maintenance.

The basic idea is to use air to pass into hot seawater to form bubbles, and absorb the heat of seawater and evaporated water vapor during the rising process of the bubbles, which is the humidification process; collect water vapor and condense to obtain fresh water, which is the dehumidification process . Wet dehumidification seawater desalination method is currently a research hotspot. It has the advantages of flexible scale, moderate equipment investment and operating costs, low heat energy utilization, low technical level requirements, and miniaturization of devices. Foreground method. In the industry, there are relatively few studies on humidification and dehumidification seawater desalination devices; therefore, the development of new and efficient humidification and dehumidification solar seawater desalination devices is of great significance.
