摘　　要：针对滤筒除尘器不同出口方式,基于计算流体力学(CFD)模拟软件采用多孔介质模型方法对滤筒除尘器内部流场均匀性进行数值分析,得到滤筒除尘器内部各个滤筒的质量流量及气流速度分布。通过流量分配系数法得出出口3模型内部流场相对其他三种出口模型流场更均匀,其中出口4模型流场均匀性较差,并发现4种模型都存在明显的射流及流场不均等问题。因此提出采用双进风口优化模型,模拟研究结果表明:优化后的四种滤筒除尘器内部流场均匀性均得到很大改善,解决了进口射流问题。According to the different outlet mode of the cartridge filter,obtaining mass flow and velocity distribution of each cartridge,based on the method that the airflow uniformity of internal flow field is analyzed CFD software and porous media model method.The internal flow field of the third outlet model is more uniform relative to the other 3 outlet models by the flow distribution coefficient,while the flow field uniformity of the fourth outlet model is the worst.There are problems that obvious jet flow and non-uniform airflow distribution happen in the all 4 models.Therefore,a double air inlet is used to optimize the model,and the simulation results show that the flow field uniformity of the 4 optimized cartridge filters is greatly improved,and the problem of jet flow is solved well.
