摘 要： 对逆流、散装填料、LiBr溶液的除湿器进行实验研究，实验过程中溶液流量为800～1600L/h，入口溶液浓度为49～54%，温度为28～41℃，空塔气速为0.39～0.96m/s，入口空气湿度为10～21g/kg。采用除湿量和体积传质系数来描述除湿性能，分析了溶液和空气入口参数对除湿性能的影响，得出平均体积传质系数，并比较了不同填料的除湿性能。同时对除湿过程进行了能量守恒分析，表明实验测量数据的准确性。实验结果为溶液除湿系统的性能分析及设计提供了依据。 关键词： 溶液除湿器 除湿量 体积传质系数 实验 Experiment on performance of liquid desiccant dehumidification Zhijia Huang, Yuehong Lu, Bo Lei School of Civil Engineering and Architecture, Anhui University of Technology, Maanshan 243002 Anhui Abstract: Experiments were carried out for a counter flow dehumidifier with random packing and LiBr solution. when solution flow was 800~1600L/h with inlet concentration and temperature of 49～54%,and 28～41℃, respectively, and the air velocity of empty tower was 0.39~0.96m/s, inlet air humidity was 10~21g/kg. The performance of dehumidification was described by moisture removal and volumetic mass transfer coefficient. The impact of the solution and the air inlet parameters on the dehumidification performance was analysed, an average volumetric mass transfer coefficient was arrived, and the performance of dehumidification by different types of packing was compared. At the same time analysis of energy conservation on the process of dehumidification was done which shows the accuracy of experimental data. the analysis of the performance and design of the liquid desiccant system is provided by the results.
