摘要:
利用计算流体力学(CFD)数值模拟方法研究双管式多孔陶瓷膜反应器内的宏观流场特性,模拟双管式多孔陶瓷膜反应器的膜分布器和膜分离器的速度场,系统考察循环流速、进料流速和催化剂含量对反应器内流体动力学特性的影响。结果表明:循环流速的增大能够提高膜表面的剪切速率,减少催化剂颗粒在膜表面的吸附。进料流速的增大能够提高膜渗透通量,促进固相催化剂的均匀分布。初始固相催化剂体积分数为0.01时,固相催化剂分散较均匀。
Abstract:
The flow field of the dual porous ceramic membrane reactor was numerically simulated with computational fluid dynamics(CFD).The velocity field of the membrane distributor and membrane separator on the dual porous ceramic membrane reactor was obtained from the simulation.The effects of circulation rate,feed rate and volume fraction of catalyst particles on hydrodynamics of the reactor were investigated.Results indicated that the flow rate on membrane surface increased with the increase of the circulation rate.The increase of the flow rate on membrane surface could reduce the adsorption of the catalyst particles.The increase of the feed rate led to the increase of membrane permeate flux and more dispersion of catalyst particles.The catalyst particles had more uniform dispersion when the volume fraction of catalyst particles was 0.01.
