摘要/Abstract

摘要：

提出一种基于溶液除湿技术对压缩空气进行深度除湿干燥的方法。搭建压缩空气溶液除湿系统性能测试实验台,以空气出口含湿量和除湿量作为除湿性能的评价指标,对LiCl-H₂O溶液用于压缩空气的逆流除湿过程进行实验研究。探讨压缩空气、溶液进口参数对空气出口含湿量以及除湿量的影响,结果表明:压力0.5 MPa下,空气出口含湿量能够达到0.9 g·kg^-1,且一定压力下系统除湿量随着空气流速、溶液质量流量、溶液质量分数的增加而增大,验证了压缩空气溶液深度除湿干燥方法在相关领域应用的可行性。

Abstract:

A novel compressed air drying method based on a pressurized liquid desiccant dehumidifier is proposed in this paper. An experimental setup of pressurized liquid desiccant dehumidifier associated with a compressed air module is established to verify the novel air drying method and further test the performance. The results show that, under the pressure of 0.5 MPa, the outlet moisture content of air can reach 0.9 g·kg^-1. The moisture removal rate increases with the increase of air velocity, solution flow rate and solution concentration under certain pressure. The feasibility of applying liquid desiccant technology to drying compressed air in related fields is verified.
