摘要

吸附式海水淡化利用蒸发器的水蒸气的离散吸附，并能够被排放到冷凝器。这项研究阐明了床层、冷凝器和蒸发器之间质量和热回收的高级循环。此外，还研究了不同操作条件下吸附脱盐系统的热力学模型。分析了其对蒸发器产蒸气和吸附床中水蒸气吸附与解吸的影响。最后，用实验数据对ADS热力学数学模型进行了验证。此外，通过床层、冷凝器和蒸发器之间的质量和热回收进行了先进的ADS建模。除了淡化水的用量外，还说明了在有和没有热回收和质量回收的过程中应用的设备的时间历史图。最后，在此工况下，先进ADS比常规ADS的比日产水量(SDWP)提高了153%。

A thermodynamic modeling of 2-bed adsorption desalination to promote main equipment performance

Adsorption desalination utilizes the discrete adsorption of the water vapor from the evaporator, and is capable of being discharged to the condenser. This study illuminated an advanced cycle of mass and heat recovery among beds, condensers, and evaporators. Morover, the thermodynamic modeling of adsorption desalination systems (ADS) under different operating conditions was investigated. Furthermore, its effect on the evaporator vapor production and the water vapor adsorption and desorption in the adsorption beds were accounted for. Parenthetically, the mathematical model of ADS thermodynamics was validated with the experimental data. Besides, the advanced ADS modeling was conducted via mass and heat recovery among beds, condensers, and evaporators. In addition to the amount of desalinated water, the time history chart of the equipment applied in the process with and without the thermal and mass recovery is also illustrated. Finally, under such operating conditions, the specific daily water production (SDWP) advanced ADS is 153% higher than conventional ADS.
