Oil-accumulating oil-absorbing vessel

Abstract

The invention relates to an oil gathering type oil sucking ship which comprises a ship body and oil sucking devices arranged on the ship body. Each oil sucking device comprises an oil sucking hood with an opening facing downwards. Negative pressure can be generated on the edges of the bottoms of the oil sucking hoods. Spiral blades and a suction nozzle are arranged in a center area in each oil sucking hood. An inlet of each suction nozzle faces downwards and is located above the corresponding spiral blades. During work, the bottoms of the oil sucking hoods are higher than a liquid level, the inlets of the suction nozzles are attached to the liquid level, and the spiral blades are lower than the liquid level. The oil sucking ship firstly collects floating oil in a treating area, then forms a thick oil layer in a centralized manner, and finally extracts away the thick oil layer in a centralized manner; and the treating efficiency is high, and the oil gathering type oil sucking ship is suitable for treating thin-layer floating oil and floating oil distributed in a large range.

Description

technical field [0001] The invention belongs to the field of oil spill treatment, and in particular relates to an oil gathering type oil suction ship. Background technique [0002] At present, the following two methods are traditionally used to deal with oil spills on water: 1) Prevent the spread of dirty oil through oil containment booms, and recover the floating oil through mechanical transmission through conveyor belts. This method requires the deployment of large-scale machinery, which is heavy and unsuitable for operation. , the conveyor belt can only recover oil spills within the distribution range and located in the thick oil slick area; 2) burn the slick oil, and use microorganisms to decompose the oil or use chemical methods to treat the oil, which will damage the water environment and will not Environmental friendly. Therefore, it is an efficient and environmentally friendly way to use oil suction ships for mobile oil suction treatment. However, the existing oil s...

[0002] At present, the following two methods are traditionally used to deal with oil spills on water: 1) Prevent the spread of dirty oil through oil containment booms, and recover the floating oil through mechanical transmission through conveyor belts. This method requires the deployment of large-scale machinery, which is heavy and unsuitable for operation. , the conveyor belt can only recover oil spills within the distribution range and located in the thick oil slick area; 2) burn the slick oil, and use microorganisms to decompose the oil or use chemical methods to treat the oil, which will damage the water environment and will not Environmental friendly

Therefore, it is an efficient and environmentally friendly way to use oil suction ships for mobile oil absorption treatment. However, the existing oil suction ships have a small treatment range and use oil pumping methods, which cannot adapt to thin oil slicks.
