The invention provides an oil-water two-phase flow separation device, system and method. The oil-water two-phase flow separation device comprises: a liquid inlet pipeline which is provided with a liquid inlet; a liquid separation pipeline, wherein when the oil-water mixed liquid enters the liquid separation pipeline, oil floats to realize oil-water separation due to different densities of the oil and water, and the liquid separation pipeline is provided with a water outlet; and an oil outlet pipeline connected with the liquid distribution pipeline, wherein the oil outlet pipeline is provided with an oil outlet, and the oil outlet is higher than the water outlet. One end of a constant-pressure pipeline is communicated with the oil outlet pipeline, and the other end is communicated with the liquid inlet pipeline. According to the principle that oil and water are different in density, oil floats upwards to achieve oil-water separation through the liquid separation pipeline, the constant-pressure pipeline enables the liquid inlet pipeline, the liquid separation pipeline, the oil outlet pipeline and the constant-pressure pipeline to form a communicating vessel, oil-water mixed liquid flows towards the oil outlet pipeline and flows into an oil outlet from the liquid inlet pipeline, and oil-water separation can be completed, so the treatment efficiency is high; and water discharged from the water outlet pipe has low oil content and can be directly discharged, so that the treatment period is shortened.
Description
technical field [0001] The invention relates to the technical field of petroleum treatment, in particular to an oil-water two-phase flow separation device, system and method. Background technique [0002] Oil pollution refers to the pollution caused by leakage and discharge of oil during oil extraction, transportation, loading and unloading, processing and use, mainly in the ocean. Oil floats on the sea surface and rapidly spreads to form an oil film, which can be migrated and transformed through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption. The oil can adhere to the gills of the fish, suffocate the fish, inhibit the spawning and hatching of waterfowl, destroy the impermeability of their feathers, and reduce the quality of aquatic products. The formation of oil film can hinder the reoxygenation of water body, affect the growth of marine plankton, and destroy the balance of marine ecology. [0003] In the prior art, th...
