Much less attention has been focused on the particle deposition in rectifying plate though it is a common problem in shale gas pipe systems. The effects of particle parameter and flow field on the deposition and distribution of particle in a new‐type rectifying plate system are investigated. Both the computational fluid dynamics (CFD) method and the experiment method are used in order to analyze the particle deposition under various conditions. The accuracy of simulation model is verified with measurements in the experiment and from analyzing, and it is found that the Boltzmann equation can well describe the relationship between gas Reynolds number and particle deposition in the rectifying plate system. It is also found from investigation that the particle deposition is greatly affected by the particle parameter. Deposition rate rises with the increase of the particle diameter; however, it reduces gradually with the decrease of particle shape factor. Moreover, the particle mass concentration is an essential dimension that can give a prediction of where the particle may deposit.

页岩气提取过程中新型精馏板系统中颗粒沉积的分析

尽管在页岩气管道系统中这是一个普遍的问题，但注意力很少集中在精馏板上的颗粒沉积上。研究了新型整流板系统中颗粒参数和流场对颗粒沉积和分布的影响。计算流体动力学（CFD）方法和实验方法均用于分析各种条件下的颗粒沉积。通过实验测量和分析，验证了仿真模型的准确性，发现玻尔兹曼方程可以很好地描述整流板系统中气体雷诺数与颗粒沉积之间的关系。从研究中还发现，颗粒参数极大地影响了颗粒的沉积。沉积速率随粒径的增加而增加；然而，随着颗粒形状因子的减小，它逐渐减小。此外，颗粒质量浓度是一个基本尺寸，可以预测颗粒可能沉积的位置。
