对采用规整波纹填料结构的溶液除湿器除湿过程进行了实验研究,空气与溶液流型组织形式为叉流,基于Le-hD分离测量法得到空气入口流量、温度、含湿量以及溶液入口质量分数、温度对耦合传质系数的影响,并采用数据回归的方法对传质系数与Lewis数进行拟合,得到该类结构除湿器除湿过程的传质系数与Lewis数的关联式,并进行了74组稳态实验对该关联式进行误差分析与验证,结果表明根据关联式计算得到的进出口参数变化与实验进出口参数变化之间相对误差很小,进出口空气温度变化、含湿量变化误差分别仅在6%、10%以内,进出口溶液温度变化相对误差不超过12%,表明Le-hD分离测量法的准确性和可接受性。
The dehumidification process of solution dehumidifier with structured corrugated packing was studied experimentally. The air and solution flow patterns were in the form of cross-flow. Based on the Le-hD separation method, the air inlet flow rate, temperature, moisture content and mass fraction , Temperature on the coupling mass transfer coefficient, and the data regression method to mass transfer coefficient and Lewis number were fitted to get the dehumidifier dehumidification process of this mass transfer coefficient and Lewis number correlation, and carried out 74 The experimental results show that the relative error between the change of the import and export parameters calculated according to the correlation formula and the change of the experimental import and export parameters is very small. The error of the change of the temperature of the inlet and outlet air and the change of the moisture content Respectively, only less than 6%, 10%, import and export of the relative change in temperature does not exceed 12% error, indicating Le-hD separation measurement accuracy and acceptability.
