The problem that water is produced to water efficiency is low, can&#39;t directly drink in order to solve desert arid area air intaking. The system consists of an adsorption type refrigerator system, a solution type air moisture collecting system, an air water taking and purifying system, a heat recovery and heat exchange system and a solar heat collecting system. The adsorption refrigerator is a cold source and a heat source, provides cold energy required by moisture accumulation for the solution moisture accumulator, and provides heat required by solution regeneration and air moisture accumulation enhancement for the air moisture accumulator through condensation heat and adsorption heat recovery. Forming high-humidity air through a two-stage solution moisture accumulation and air moisture accumulation process; then the water is enriched by an air adsorption type water taking device, and the water is heated, desorbed and released to a water taking evaporator to be condensed and taken, and the water quality is deeply purified. The invention can be combined with a plurality of heat recovery devices at the same time to synchronously realize the recovery and utilization of the adsorption heat and the condensation heat.)

一种沙漠、干旱区吸附制冷系统驱动的溶液-空气聚湿取水系 统及方法

技术领域

本发明涉及一种溶液-空气聚湿取水系统及方法。

背景技术

从空气中取水是为沙漠、干旱区域提供淡水资源的重要方法。通过电动压缩式制冷系统从空气中进行直接冷凝取水是干旱、沙漠地区常用的空气取水方式;但存在制冷系统耗电量大和产水效率低等问题。与直接冷凝取水技术相比,太阳能吸附式取水技术可在一定程度上降低电能消耗,但因其难以实现连续运行,从而限制了该技术的产水效率和应用范围。利用金属盐溶液吸收取水技术在一定程度上提高了空气取水效能,但存在水质不适合直接饮用的问题,从金属盐溶液提取淡水同样需要消耗大量的能源。因此,高能效、产率高、可直接饮用的绿色节能型空气取水技术与装置的研发具有重要的应用价值。
