摘要
针对折流式超重力床(RZB)功耗过高的问题,开发了一种新型的整体旋转折流式超重力床(nRZB)。以水为介质进行实验,考察了液量及转速对液相功耗的影响,并建立了液相功耗的计算模型。实验结果表明,液相功耗随液量的增大近似呈线性增大,随转速平方的增大亦近似呈线性增大;由实验数据回归得到液相功耗计算模型的参数,实验值与模型计算值的平均相对偏差为5.3%;在相同的操作条件情况下,n RZB的液相功耗降低了65%~75%,每块理论塔板液相功耗降低了约35%。
In order to solving the problem that power consumption of rotating zigzag bed(RZB) was relatively high,a novel wholly rotating zigzag bed(nRZB) was designed. Water was used as experimental medium,the effects of liquid flow rate and rotor speed on liquid power consumption were studied. Moreover,the model of liquid power consumption was established. The results showed that the liquid power consumption increased approximately linearly with the increase of liquid ?ow rate and the increase of the rotor speed squared value. Besides,the average relative deviation between experimental and calculated liquid power consumption was 5.3%. The results showed that,at the same operating conditions,liquid power consumption of nRZB reduced by 65%-75%,and liquid power consumption of per theoretical plate of nRZB reduced by about 35%.
