摘要
混凝反应效果的好坏受到絮凝剂种类、搅拌条件、设备结构等诸多因素的影响.本文从设备本身的细节优化出发,分别对磁混凝反应器流场介质分布规律、磁粉沉淀规律和搅拌机功率等进行了系列流场分析,在防止磁粉沉积并保证絮凝效果的基础上减小电机功率,能显著降低能耗,减少设备及运行成本.经数值分析后再进一步对设备总体结构进行优化,将三级搅拌减少为二级搅拌,一方面减小了设备占地面积,另一方面引入中心导流筒增强了流体的紊流状态,使絮凝效果更好,缩短了反应时间.
Abstract
The effect of coagulation reaction is influenced by many factors,such as flocculant types,mixing conditions,equipment structure and so on.In this paper,starting from the details optimization of the equipment itself,a series of flow field analyses were made on the media distribution law,magnetic powder deposition law and mixer power in the magnetic coagulation reactor respectively.On the basis of preventing magnetic powder deposition and ensuring flocculation effect,reducing motor power could significantly reduce energy consumption and equipment and operating costs.After numerical analysis,the overall structure of the equipment was further optimized,and the three-stage stirring was reduced to two-stage stirring,which on the one hand reduced the occupied area of the equipment,and on the other time introduced the central draft tube to enhance the turbulent state of the fluid,which made the flocculation effect better and shortened the reaction time.
