Flow Field Simulation And Experimental Study On Axial Deoiling Hydroclone Of Compact Structure With Guide Vane

Through improving the structures of the traditional liquid-liquid hydrocyclone, the new hydrocyclone can achieve miniaturization and being compact in the size, simultaneously must be guaranteed that it can have the big process load and the high separation efficiency. In the article through using the guide vane to realize that the fluid enters axially, the cyclone's compact structure suits to be applied in the narrow slender space such as in the down-hole pipe.Using the Fluent software to simulate and analyze the axial-flow hydrocyclone with different design parameter's guide vane, observe its flow field characteristic, analyze the influence of the guide vane's design parameter to the velocity field and the pressure field, grasp its separation mechanism further, understand more about the new structure hydrocyclone, determine the best structure size of the guide vane and the prototypical model.Through the experiments of different operating parameters, such as the current capacity, the divergence compare and so on, verify the influence to the separation efficiency. Prove the high deoiling characteristic of the new hydrocyclone, as well as the feasibility of using the simulation to carry on the optimization design. With the suitable operating parameter, the new hydrocyclone is possible to achieve a high separation efficiency, which accesses to the results of the simulation. Then, analyze the problems in the experiments and where needs to be improved in the new structure. The basis of the new type used in downhole oil-water separation in the future is provided.This article provides certain rationale and references to study the separation characteristic and the structure optimization design of the fluid-fluid hydrocyclone further.
