【摘要】：在压缩空气溶液除湿实验平台上,分别以LiBr和LiCl水溶液作为除湿剂,实验研究了两种溶液在压缩空气溶液除湿系统中的除湿性能。以溶液表面水蒸气分压力作为比较基准,压缩空气出口含湿量和除湿量作为除湿性能的评价指标,对二者的除湿能力进行比较分析。同时基于压缩空气溶液除湿器传热传质模型,结合实验数据,研究了LiBr、LiCl溶液与压缩空气间的传质系数大小以及变化规律。结果表明:在相同的处理工况下,采用LiCl溶液对压缩空气进行除湿能得到更低的空气出口含湿量和更高的除湿量,LiCl溶液除湿过程的传质系数也高于LiBr溶液,即在压缩空气溶液除湿系统中LiCl溶液具有更优的除湿能力和传质性能。
[Abstract]:The dehumidification properties of LiBr and LiCl aqueous solutions in compressed air solution dehumidification system were studied on a compressed air solution dehumidification test platform. The moisture content and dehumidification at the outlet of compressed air were taken as the evaluation index of the dehumidification performance, and the dehumidification ability of the two was compared and analyzed. Based on the heat and mass transfer model of compressed air solution dehumidifier and experimental data, the mass transfer coefficient between LiBr,LiCl solution and compressed air is studied. The results show that under the same treatment conditions, the dehumidification of compressed air by LiCl solution can get lower air moisture content and higher dehumidification rate, and the mass transfer coefficient of LiCl solution is also higher than that of LiBr solution. In the compressed air solution dehumidification system, LiCl solution has better dehumidification ability and mass transfer performance.
