AI Technical Summary
Existing cyclone desanding devices have difficulty effectively separating oil sands when processing high-pressure fracturing flowback fluid, resulting in high oil content in the overflow liquid, which affects subsequent reuse or discharge.
The design combines a hydrocyclone and an electrode assembly, utilizing the synergistic effect of centrifugal force and an electric field to achieve oil-water-sand separation. The tangential placement of the hydrocyclone's inlet, outlet, outlet, and sand outlet, combined with the electric field provided by the electrode assembly, demulsifies and separates the oil and sand.
It effectively reduces the oil sand content in the backflow fluid, improves the reusability and discharge quality of the liquid, and reduces environmental pollution.
