Description

Oil-water separation device for offshore spilled oil

Technical Field

The utility model relates to an oil spilling handles technical field, especially relates to an oil-water separator of marine oil spilling.

Background

Pollution caused by petroleum and products thereof entering the marine environment in the processes of exploitation, refining, storage and use. The discharge of various oily wastewater, marine ship ballast water and tank washing water, oil ship distress, oil pipeline leakage and offshore oil exploitation, etc. are all important ways of marine oil pollution. Oil film on the sea surface can obstruct gas exchange between the atmosphere and the sea water, and influences photosynthesis of marine plants. After fur of sea beasts and feathers of sea birds are polluted by petroleum, the heat preservation, swimming or flying capabilities are lost. Petroleum pollutants can also interfere the ingestion, reproduction and growth and development of marine organisms, change the migration route of fishes, pollute fishing gear and fishery, and make marine products have petroleum flavor and cannot be eaten.

In addition, an oil film formed by oil on the sea surface can block gas exchange between the atmosphere and the seawater, so that absorption, transmission and reflection of electromagnetic radiation by the sea surface are influenced, and potential influence is caused on long-term climate change. The oil in the sea surface and seawater can dissolve oleophilic components in pollutants such as halogenated hydrocarbon and the like, and the migration and conversion rate between interfaces is reduced. Meanwhile, petroleum pollution also damages the seaside scenic spots and bathing beaches.

The existing oil stain recovery method comprises the following steps: physical treatment method, chemical treatment method, and biological treatment method. The physical treatment method mostly adopts a fence method to surround the leaked oil stain, and adopts an oil skimmer or an oil absorption material to recover overflowed oil. However, sea surface wind is large and waves are large, oil spilling area is often large, time consumption in the recovery process is long, oil spilling diffusion is caused, and recovery efficiency is low. In addition, the oil spill generation area is likely to occur in a sea area with shallow water depth, an oil spill recovery ship modified by a large oil tanker is inconvenient to enter and process, the small ship has limited storage capacity and low recovery efficiency, and oil spill diffusion is easily caused.
