technical field

The utility model relates to a recovery and cleaning device for oil spilled on the water surface, in particular to a ship-borne offshore oil spill recovery and cleaning device used for quickly cleaning the oil floating on the water surface when the ship oil spills, the submarine pipeline leaks, and the submarine oil well blows out.

Background technique

With the development of offshore oil fields and oil transportation, the risk of oil spill accidents at sea is also increasing. Once an oil spill occurs, it often causes huge economic losses and serious ecological disasters. Therefore, it is of great significance to recover and clean up the spilled oil on the sea as much as possible to reduce the loss and impact of accidents.

One of the important means of oil spill recovery and cleaning on water surface is physical and mechanical method. At present, its main forms are adhesion type, weir type, dynamic slope type, vacuum suction type, cyclone separation type and so on. Among them, cyclone separation is a method that considers the density difference between media and uses centrifugal force to separate media of different densities. It is widely used in sewage treatment, downhole oil-water separation, etc. Considering that the density of floating oil on the water surface is lower than that of water, in the vortex movement, due to the difference in centrifugal force between the oil and water, the floating oil will accumulate towards the center to form an inverted cone-shaped accumulation area. Using this principle, the surface floating oil and water body can be effectively separated.
