摘要
旋转填料床气相压降性能是超重力技术工程应用和工程设计的一项重要指标．以空气一水为介质，在气体流量0～1300m^3／h，液体流量0～7m^3／h的中试规模对错流旋转填料床的气相压降进行了模型化及实验研究．结果表明：错流旋转填料床的气相压降随气体流速、超重力因子的增加而显著增加；超重力因子对于气相压降的影响呈线性关系；液体喷淋密度的增加会造成气相压降的增加，但增加的程度随气体流速的增加而增加，随超重力因子的增强而减弱．经实验数据拟合，确定了压降模型的参数，得到计算气相压降的关联式，为错流旋转填料床压降的计算提供了依据．
Abstract： The gas pressure drop of a cross-flow rotating packed bed was an important indicator for its engi- neering application and design. Modeling and experimental analysis were studied on the gas pressure drop with air-water system in a pilot scale in which the gas flow rate was varied from 0 to 1 300 m3/h and liquid flow rate was ranged from 0 to 7 m3/h. Results show that the gas pressure drop increases with gas velocity and su- per gravity factor obviously. It is linear relationship between super gravity factor and gas pressure drop. In- creasing liquid spray density increases gas pressure drop but the trend is more evident with larger gas velocity or lower super gravity factor. The correlative expression of gas pressure drop of a cross-flow rotating packed bed in which the parameters are determined by fitting the experimental data is obtained and this provides the basis for calculating the gas pressure drop of a cross-flow rotating packed bed.
