The Simulation of the Circumfluence and Inhomogeneous Flow Field in Pulsing Electro-Floatation
Due to the large-scale violent circumfiuence occurred in the traditional electro-floatation (TEF),the interference to the mixture of micro-bubbles and floccules should not be neglected in the floatation.In this paper,the Pulsing Electro-Floatation (PEF) using square wave impulse direct current has been presented.The circumfluence in the inhomogeneous field of the PEF would be gentler than TEF,and the energy utilization rate would be improved.Based the theory of multiphase flow continuous medium,the conservation of momentum equation in the inhomogeneous flow field of PEF has been obtained,and liquid-bubble flow field of the PEF has been simulated using the Fluent module of the ANSYS 13.0.The research result shows that the inhomogeneous flow field in PEF has more reasonable energy distribution,less extent of circumfluence in the process of the micro-bubbles floating,and more benefit for the development and floatation of the bubbles-floccules mixture compared with the TEF.With the same current density,the energy consumption of PEF is 1/4-1/3 that of TEF,but has the similar floatation effect with TEF.
