摘　　要：为解决砂浆颗粒气力输送过程中物料的输送效率低以及弯管处所受到的磨损较大的问题,提出了基于ANASY FLUENT模块的仿真研究。首先,是对气力输送装置的三维建模,确定合适的输送装置;其次,再对气固混合物在管道中的运动进行受力分析,得到颗粒群在管道中运动的微分方程为后续的仿真进行验证;最后,对砂浆颗粒的水平管道进行不同的气体输入速度研究及对弯管处进行不同弯径比的仿真。通过对比不同气力输送的入口速度对气相和固相在管道中的运动分布以及对比不同弯径的弯管下的气相压力云图,得出了适合砂浆颗粒输送的最佳速度以及最优的弯径比。In order to solve the problems of low conveying efficiency of slurry particles and great wear of pipe bending space during pneumatic conveying,a simulation study based on ANASY FLUENT module was proposed.Firstly,the three-dimensional modeling of pneumatic conveying device is carried out to determine the appropriate conveying device.Secondly,the movement of the gas-solid mixture in the pipeline is analyzed,and the differential equation of particle group movement in the pipeline is obtained,which is verified by the subsequent simulation.Finally,different gas input velocity of horizontal pipe with mortar particles is studied and different bending diameter ratio is simulated.By comparing the movement distribution of the gas phase and the solid phase in the pipeline with the inlet velocity of different pneumatic conveying,and comparing the gas phase pressure cloud image under the bending pipe with different bending diameter,the optimal velocity and the optimal bending diameter ratio for the slurry particle conveying are obtained.
