以空气-水为研究体系，在并流旋转填充床内采用整体式碳化硅(SiC)填料，利用单因素法，分别考察了转速、气量对干床压降的影响以及转速、气量、液量对湿床压降的影响。实验结果表明，对于干床压降，压降随转速的增大而减小，随气量增大而增大。当气量为183 m3?h-1、转速为1400 r?min-1时，压降为-140 Pa左右；对于湿床压降，压降随转速增大而减小，随气量增大而增大，液量变化对湿床压降影响不大。当气量为183 m3?h-1、液量为340 L?h-1、转速为1400 r?min-1时，湿床压降为-160 Pa左右。通过对实验数据的关联，分别得到了干床和湿床压降的关联式，与实验结果的偏差均在±15%以内。

Gas pressure drop was studied in a co-current rotating packed bed (CO-RPB) filled with structured SiC by an air-water system. According to the single factor method, effects of rotational speed, gas flow rate on the gas pressure drop were examined in the dry CO-RPB, while effects of rotational speed, gas flow rate, liquid flow rate on the gas pressure drop were investigated in the wet CO-RPB. Experimental results show that the gas pressure drop decreases with the increase of rotational speed and increases with the increase of the gas flow rate in the dry CO-RPB. When the gas flow rate is 183 m3?h-1 and rotational speed is 1400 r?min-1, the dry bed gas pressure drop is about-140 Pa. In the wet CO-RPB, the gas pressure drop decreases with the increase of the rotational speed and increases with the increase of the gas flow rate. However, the gas pressure drop is almost constant with the increase of liquid flow rate. When the gas flow rate is 183 m3?h-1 and liquid flow rate is 340 L?h-1 with a rotational speed of 1400 r?min-1, the wet bed gas pressure drop is about-160 Pa. Two empirical correlations for estimating the gas pressure drop in the dry and wet CO-RPB are proposed. The deviation of gas pressure drop predicted from the two correlations is within ±15%of the experimental data.
