摘要：研究了采用木质结构填料的液体干燥剂再生器对三甘醇（TEG）的再生性能。研究了空气和干燥剂流速、空气和干燥剂温度以及干燥剂浓度对再生过程的影响。从水分蒸发速率和再生过程的有效性方面评价了这些参数对干燥剂再生器性能的影响。研究发现，在本研究条件下，干燥剂进口温度是对再生过程最有利的变量，而进口干燥剂浓度是最不利的变量。气团通量增加了水的蒸发速率，但显著降低了蓄热器的效率。其他参数的影响可以忽略不计。本研究结果与Chung和Luo的相关关系及已发表的文献一致。
Abstract The performance of a liquid desiccant regenerator, equipped with structured packing made of wood, was investigated for the regeneration of triethylene glycol (TEG). The effects of air and desiccant flow rates, air and desiccant temperature, and desiccant concentration were studied to assess their impact on the regeneration process. The influence of these parameters on the performance of the desiccant regenerator was evaluated in terms of the rate of water evaporation and the effectiveness of the regeneration process. It was found that under the conditions of this study, the desiccant inlet temperature was the most favorable variable, while the inlet desiccant concentration was the least favorable with respect to the regeneration process. The air mass flux increased the rate of water evaporation, but reduced the regenerator effectiveness significantly. The other parameters had a negligible effect. The results of this study were in agreement with the Chung and Luo correlation and published literature.
