摘要: 以空气?水为研究体系,采用单因素法,在气流剪切错流旋转填料床中分别考察了气速、超重力因子对干床压降的影响及气速、超重力因子和液体喷淋密度对湿床压降的影响. 结果表明,气流剪切错流旋转填料床干、湿床压降均随气速和超重力因子增大而增大;气速较低、超重力因子较大时,湿床压降随液体喷淋密度增大而减小;在高气速和小超重力因子时,湿床压降随液体喷淋密度增大而增大. 关联实验数据可得到气流剪切错流旋转填料床的压降关联式,与实验结果的偏差在±15%以内.

Abstract: Gas pressure drop was studied in Gas-phase Sheared Cross?Flow Rotating Packed Bed (GSC?RPB) by an air?water system. According to the single factor method, the effects of gas velocity, high gravity factor on dry pressure drop were examined, and the effects of gas velocity, high gravity factor and liquid spray density on wet pressure drop were investigated. The results showed that the dry pressure drop and wet pressure drop increase with the increase of gas velocity and high gravity factor. In the case of low gas velocity and big high gravity factor, the wet pressure drop decreases with the increase of liquid spray density. While in the case of high gas velocity and small high gravity factor, the wet pressure drop increases with the increase of liquid spray density. The empirical correlations for estimating the dry and wet pressure drop are proposed. The deviation of gas pressure drop predicted from the correlation is within ±15% of the experimental data.
