根据桥孔填料结构的特点及操作因素，分析了气流在填料床内的混合过程，通过物料平衡计算，建立了描述气流分布的多参数的混合池数学模型。模型计算结果与实验结果符合较好。关键词##4填料;;气流分布;;混合;;数学模型
According to the characteristics and operating factors of bridge pore packing structure, the mixing process of gas flow in packed bed was analyzed. Based on the material balance calculation, a mathematical model of multi-parameter mixed pool describing gas flow distribution was established. The model calculation results are in good agreement with the experimental results. Keywords ## 4 packing; airflow distribution; mixing; mathematical model
