摘要
颗粒物凝并技术是强化超细颗粒粉尘收集和脱除的有效方法。基于FLUENT软件对角型管道式凝并器的凝并区内流场进行了数值模拟,结果表明:凝并区内设置的横条可以产生扰流效果,为超细颗粒的碰撞凝并创造良好条件;综合考虑扰流效果和压力降,设置3组角型横条,角型开口角度设置90°是优化选择。
The technology of particles is a kind of effective method to strengthen the ultrafine particles’ collection and removal. The flow field of the turbulence coalescence device was simulated by FLUENT,and the results show that diaphragms in the turbulence coalescence device are good at producing vortices,which could creat favorable conditions for the aggregation of the ultrafine particle. After a comprehensive consideration of vortices and the pressure drop,3 groups of diaphragms and 90°of diaphragm angle are thought of optimal design.
