Description

A marine oil spill recovery device

technical field

The invention relates to the technical field of dirty oil collection, in particular to a marine oil spill recovery device.

Background technique

In recent years, the petroleum industry has developed rapidly. As an important energy material and chemical raw material, petroleum has become increasingly important to the national economy. At the same time, the environmental hazards caused by petroleum have become increasingly prominent. As the main transportation mode of oil, marine transportation, oil spill accidents occur from time to time, mainly through the following four ways: 1) oil tanker accident; 2) drilling platform explosion; 3) oil pipeline leakage; 4) man-made discharge; There are nearly one million tons of oil discharged into the ocean due to oil transportation, and oil spill pollution has become one of the major sources of ocean pollution. The density of crude oil is lower than that of seawater, and it is easy to weather. Under the impact of sea waves and sea wind, the spilled oil spreads rapidly to form an oil film, which hinders the reoxygenation of water bodies and affects the growth of marine plankton. Suffocation inhibits the spawning and hatching of aquatic birds, destroys the impermeability of their feathers, and reduces the quality of aquatic products. This not only has a serious impact on the marine ecological environment and the economy of coastal areas, but also poses severe challenges to subsequent disposal and prevention and control management. Therefore, in the face of spilled oil, it should be recovered as soon as possible.

Chinese patent CN202010962017.0 proposes a marine oil spill recovery device including a hull and an oil absorption unit located on the hull, an oil squeeze unit, an oil storage unit, an oil product packaging unit and an oil product transfer unit; the control unit and the oil suction unit, oil squeeze unit The oil unit, oil storage unit, oil product packaging unit and oil product transfer unit are connected separately; the oil squeeze unit is used to squeeze the spilled oil absorbed by the oil absorption unit to the oil storage unit; the oil product packaging unit is used to clean the oil storage unit The spilled oil in the tank is repackaged; the oil transfer unit is used to transfer the repacked oil out of the hull.

Although the above-mentioned technical solution can collect and clean up the oil spill on the sea surface, when the oil spill leaks, it will soon spread on the sea surface, resulting in a very large area to be cleaned.
