压缩空气溶液除湿中不同除湿剂除湿性能比较
Comparison of drying performance of compressed air drying system using different pressurized liquid desiccants
摘要
Abstract
To compare the difference of drying performance and mass transfer ability between LiCl and LiBr solution used in the compressed air drying system, the experiments were performed using LiCl and LiBr solution, respectively. The drying performance was compared on the basis of the same solution temperature and surface vapor pressure. The mass transfer coefficients between compressed air and LiCl liquid desiccant were calculated based on the heat and mass transfer model. The results indicated that the humidity ratio of air using LiCl liquid desiccant was lower and the moisture removal rate was higher than LiBr in the same experimental operating conditions, while the mass transfer coefficients between compressed air and LiCl liquid desiccant were higher than LiBr. It was concluded that using LiCl liquid desiccant can obtain better drying performance and mass transfer ability in compressed air drying system.关键词
