Abstract
Rotating zigzag bed(RZB) is a novel kind of HIGEE equipment with concentric rings. Motor power consumption is an important factor to be considered when researchers design RZB. In this paper,experimental studies on the effective power consumption of RZB were preliminarily carried out. A new calculation method was proposed,which provided basis for studies on power consumption of rotating equipments and industrial applications of RZB. The effective power consumption of RZB could be divided into two parts:power consumption to disperse liquid and to accelerate liquid. The calculation model of the effective power consumption of RZB was achieved by theoretical analysis. Using water as test system,the effective power consumption was experimentally measured. According to the experimental data,the effective power consumption approximately linearly increased with liquid flowrate when rotating speed was constant. The higher rotating speed was,the more rapidly effective power consumption increased. Based on the experimental data,the model of effective power consumption with liquid flowrate and rotating speed for rotor with single concentric ring could be achieved. The relative deviation between the experimental data and the calculated values was within 20%. The calculated effective power consumption of RZB with four concentric rings is about 20% higher than the measured values,which is of certain significance for scale-up of RZB.关键词
