应用已建立的提升管反应器气液固３相流动反应模型，对两套工业馏分油催化裂化装置的提升管反应器内的流动、传热及裂化反应进行了系统的数值模拟，得到了原料油液雾流动与气化状况的实际图像。模拟结果表明，原料液雾相的流动是非常复杂的，在轴向、径向和圆周方向上都存在较大的梯度，且表现出与气固两相相似的流动形态。原料油液雾生存区，自下而上由小变大又变小；自轴线向边壁由大变小。随着气化过程的进行，液雾颗粒相的整个特性都在发生变化，正是这一复杂的气化过程，对其它两相的流动、传热及反应产生重要的影响
The flow, heat transfer and cracking reactions in riser reactor of two sets of industrial distillate catalytic cracking unit were systematically simulated by using the established three-phase flow-reaction model of gas-liquid-solid flow in riser reactor. Actual image of oil mist flow and gasification conditions. The simulation results show that the flow of the mist phase of the raw material liquid is very complicated. There is a large gradient in the axial, radial and circumferential directions, and the flow pattern is similar to that of the gas-solid two phases. Raw oil mist survival area, bottom-up from small to large and smaller; from the axis to the wall from big to small. As the gasification process progresses, the overall characteristics of the liquid phase of the mist are changing. It is this complex gasification process that has a significant effect on the flow, heat transfer and reaction of the other two phases
