Abstract
For the problem of difficulty in achieving efficient and economical demulsification and dewatering of emulsified oil by a single method,a coupling device,which couples the swirl centrifugal field and the electric field was used to achieve high-efficiency demulsification and dewatering.The influence of oil viscosity on oil-water separation performance of the dual-field coupling device was investigated by the multiphase flow governing equations and electric field governing equation.The results show that the external electric field can promote the coalescence of droplets,and the coalescence of droplets will lead to decrease in the viscosity of the mixed phase,thereby increasing the tangential velocity of the cone section and the average particle size of the droplets,which is conducive to oil-water separation.And the dehydration rate and deoiling rate of oil with a viscosity of 6.42 mPa·s are 16.3%and 29.3%higher than those of the oil with a viscosity of 19.35 mPa·s.The calculation results can provide a reference for the design of a dual-field coupling device suitable for high-viscosity oil-liquid separation.关键词
