摘要
通过建立离散颗粒运动数学模型 ,对移动颗粒层过滤除尘器中粉尘颗粒与过滤介质颗粒碰撞以及对除尘效率的影响进行了初步研究 .模拟计算了碰撞次数与系统风速之间的变化关系 .与实验结果对比发现 ,随系统风速的变化 ,颗粒碰撞频次与除尘效率之间存在定性的一致 .
A mathematical model to simulate the discrete particle behavior in a moving granular bed dust filter was established.The experiments prove that the collision times between the dust particles and filter particles change with the dusty air velocity and the variation is qualitatively identical with the change of dust removal efficiency.Preliminary research shows that particles collision has important effect on the dust removal efficiency.
