Optimization of Flow Deflector Quantities for Gravity Oil-Water Separator

The internal structure and the working principle of gravity oil-water separator used for self-circulation well-flushing equipment were introduced. Based on CFD, the flow field was calculated and analyzed with different quantities of horizontal deflectors and inclined deflectors in the separator. According to velocity vector diagrams and oil drop trajectory diagrams with different number of horizontal deflectors and inclined deflectors, the influence rules on separation efficiency were analyzed. The results show that the separation efficiency is improved gradually with the amount of horizontal deflectors increased, and the optimal value of separation efficiency is 3 inclined deflectors.
