摘要: 利用改进的柱状气液旋流器(GLCC)机械设计模型计算并预测出该模型的气液耦合流动的流变水力特性,如临界速率、平衡液位高度、零净液体流量及液体携带起始点等。柱状气液旋流器机械设计模型的确定对平衡液位模型和气-液界面模型的建立有重要意义。推导出了净液体流量为零时的最大液体容量,并得出在一种临界参数下气体中无液体携带和液体中无气体携带的条件。液体携带起始点的提出和预测为获得较为完整的气液耦合流变临界操作参数提供了依据,而且为今后柱状气液旋流器的推广应用提供了参考。

Abstract: The improved mechanistic model of gas-liquid cylindrical cyclone separators(GLCC)was used to compute and predict hydrodynamics of rheological property of gas-liquid coupling flow,including the critical velocity parameter,equilibrium liquid level,zero-net liquid flow,liquid carry-over point.The determination of mechanistic model for GLCC has the important reference for establishing the models of equilibrium liquid level and gas-liquid interface.The biggest liquid volume was obtained when the net liquid flow was zero.At the same time,a certain critical parameter under the conditions of no liquid carry-over or gas carry-under was also obtained.The prediction of liquid carry-over point can provide a certain basis for obtaining the total critical operating parameter for rheological property of gas-liquid coupling flow.This research can provide reference for the industrial application of GLCC.

Key words: gas-liquid cylindrical cyclone separator, gas-liquid coupling flow, hydrodynamics, equilibrium liquid level, zeronet liquidflow, gas-liquid interface, mathematical model
