摘要
建立了动态法测量除湿溶液表面蒸汽压的实验台,测量了LiCl溶液、CaCl2溶液及不同配比的LiCl和CaCl2混合溶液的表面蒸汽压。结果显示,随着LiCl在混合溶质中质量分数的增加,对降低溶液表面蒸汽压的作用逐渐减小。综合分析除湿工况下混合溶液的表面蒸汽压及其成本,认为50%CaCl2+50%LiCl混合溶液是一种性能优良、价格合理的液体除湿剂。
Sets up an experimental table for dynamically measuring surface vapor pressure of liquid desiccant, and measures the surface vapor pressure of LiCl solution, CaCl2 solution and mixed solution of LiCl and CaCl2 in different proportions, The results show that the more the LiCl mass percentage is, the less the surface vapor pressure reduction is by adding LiCl, By a rounded analysis of surface vapor pressure and costs of the mixed solution, considers that the mixed solution of 50% CaCl2 and 50% LiCl is a liquid desiccant good in both performance and cost.
