Abstract
Description
Technical Field
[0001] The present application relates to the technical field of oil and gas recovery devices, and in particular to an offshore oil spill cleaning device. Background Art
[0002] With the rapid development of modern society, oil is widely used as an important energy source. Once crude oil leaks at sea, it will cause significant economic losses and environmental damage. In traditional technology, there are many ways to clean up oil spills. Common methods can be divided into:
[0003] Physical treatment method: adsorption through oil absorbent felt, use oil absorbent felt to absorb the floating oil to the surface, and then remove it from the water. This method is suitable for cleaning up small areas of floating oil; using oil-water separator: by using an oil-water separator, the floating oil can be separated from the water to achieve the purpose of cleaning; grease trap separation: using the principle of the grease trap, the floating oil can be separated and centrally treated.
[0004] Chemical treatment: Treat by spraying various chemicals, such as throwing dispersants: throwing dispersants on the floating oil to quickly disperse it into the water. This method can dissolve or emulsify the floating oil, thereby reducing the difficulty of cleaning.
[0005] Biological treatment: uses the ability of certain microorganisms to oxidize and decompose oil to remove oil from the sea. This method is often used in combination with other methods to further reduce the residue of oil spills.
[0006] Each treatment method has certain advantages and disadvantages. The physical treatment method is expensive, but it is less harmful to the marine environment than the chemical treatment method, while the biological treatment method is slow to take effect and needs to be used in conjunction with other treatment methods. Therefore, there is an urgent need for a cleaning device that can reduce the cost of physical treatment methods and improve treatment efficiency. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] In response to the above problems, an embodiment of the present application provides an offshore oil spill cleaning device, which can promptly treat the sea surface where oil pollution is generated, reduce treatment costs, and improve cleaning efficiency.
[0027] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0028] See also Figure 1-2 The offshore oil spill cleaning device includes a cleaning ship 1, a suction device arranged on the cleaning ship 1, a three-phase separator 7 and an oil tank 5 arranged in the cleaning ship 1, the suction device is connected to the three-phase separator 7, and the three-phase separator 7 is connected to the oil tank 5.
[0029] The suction device includes an extraction pump 3, an oil extraction pipe 4 connected to the water inlet of the extraction pump 3, and an oil outlet pipe 6 connected to the outlet of the extraction pump 3. The oil outlet pipe 6 is connected to the inlet of the three-phase separator 7. The top of the three-phase separator 7 is provided with an air outlet 10 connected to the atmosphere, and the top is provided with a drain port 13 and an oil outlet 12. The oil outlet 12 is located on a side close to the inlet of the three-phase separator 7 and is connected to the oil tank 5.
[0030] During operation, after the cleaning ship 1 moves to the designated position, the extraction pump 3 is started by remote control or by the onboard personnel. Specifically, the extraction pump 3 is a centrifugal pump. The seawater with oil pollution is extracted together through the extraction pump 3 and transported to the three-phase separator 7 for separation. The air outlet 10 and the drain outlet 13 directly discharge the separated gas and water to avoid the recovery efficiency being reduced due to the recovery of too much water vapor, and the oil discharge outlet 12 is connected to the channel oil tank 5, and the oil tank 5 is used for recovery and reprocessing.
[0031] The main method of the present application is to integrate the suction device, the separation device and the storage device. On the one hand, the three-phase separation of oil, gas and water is directly carried out after extraction, and the separated oil is recovered by using the oil tank 5. On the other hand, the oil tank 5 can also be connected to the transmission pipeline to the total oil storage ship. By using multiple small boats for simultaneous cleaning, the cleaning efficiency can be effectively improved.
[0032] In some embodiments, a detachable filter cartridge 8 is provided at the inlet of the three-phase separator 7 , and an inlet baffle 9 is provided at the rear end of the detachable filter cartridge 8 .
[0033] During operation, the solid particles contained in the oil are intercepted by the detachable filter cartridge 8 at the inlet end of the three-phase separator 7, and the extracted solids are processed in a centralized manner, which can effectively reduce the number of cleaning times inside the three-phase separator 7 and save economic costs; and an inlet baffle 9 is also provided at the inlet to prevent the splashing of the pumped seawater.
[0034] In some embodiments, the upper end of the oil drain port 12 is connected to the oil collecting barrel 11 through an oil drain pipe, and the two ends of the oil collecting barrel 11 fit the front and rear inner walls of the three-phase separator 7, and the side plate of the oil collecting barrel 11 close to the inlet of the three-phase separator 7 is lower than the side plate of the oil collecting barrel 11 away from the inlet of the three-phase separator 7, and an overflow baffle 14 is arranged between the water outlet 13 and the oil drain port 12, and the two ends of the overflow baffle 14 fit the front and rear inner walls of the three-phase separator 7, and the height of the overflow baffle 14 is higher than the side plate of the oil collecting barrel 11 close to the inlet of the three-phase separator 7, and lower than the side plate of the oil collecting barrel 11 away from the inlet of the three-phase separator 7.
[0035] During operation, due to the presence of the overflow baffle 14, the water level on the left side of the overflow baffle 14 is always higher than the side plate of the oil collecting barrel 11 close to the inlet of the three-phase separator 7. The upper floating oil enters the oil collecting barrel 11 from the side plate of the oil collecting barrel 11 close to the inlet of the three-phase separator 7, while the side plate of the oil collecting barrel 11 away from the inlet of the three-phase separator 7 is higher than the height of the overflow baffle 14, preventing the oil from flowing out. After the upper floating oil enters the oil collecting barrel 11, it flows into the oil tank 5 from the oil discharge port 12 for recovery.
[0036] In some embodiments, both the water outlet 13 and the oil outlet 12 are provided with vortex breakers.
[0037] During operation, the vortex preventer can effectively prevent vortices from forming at the water outlet 13 and the oil outlet 12 .
[0038] In some embodiments, anti-corrosion baffles 2 are provided on both sides of the cleaning vessel 1 .
[0039] During operation, petroleum oil pollution is highly corrosive. Anti-corrosion baffles 2 are arranged on both sides of the hull to avoid rapid corrosion of the cleaning ship 1, which increases the subsequent maintenance cost.
[0040] Working process of this application:
[0041] In specific use, if the oil pollution area is small, the cleaning device provided by the utility model can be used alone. After the cleaning ship 1 moves to the designated position, the extraction pump 3 is started by remote control or by the onboard personnel. Specifically, the extraction pump 3 is a centrifugal pump. The seawater with oil pollution is extracted by the extraction pump 3 and transported to the three-phase separator 7 for separation. When entering the three-phase separator 7, the solid particles in the oil pollution are intercepted by the detachable filter cartridge 8 at the inlet end of the three-phase separator 7, and the extracted solids are processed in a centralized manner, which can effectively reduce the number of cleaning times inside the three-phase separator 7 and save economic costs. In addition, an inlet baffle 9 is provided at the inlet to prevent the splashing of the pumped seawater. In the three-phase separator 7, the oil pollution is separated into three phases of oil, gas and water by the action of the three-phase separator 7. The water has the largest specific gravity and is concentrated in the bottom layer, while the oil floating on the water surface is concentrated in the oil collecting barrel 11, and the overflow partition 14 is used to separate the oil discharge port 12 and the drain port 13. Of course, a wave-breaking plate can also be set to avoid the problem of repeated discharge caused by the upper oil surface entering the drain port 13 area due to the influence of wind and waves on the sea surface. Finally, the oil, gas and water are discharged separately through the different discharge ports of the three-phase separator 7, and the oil discharge port 12 is connected to the channel oil tank 5, and the oil tank 5 is used for recycling and reprocessing. When dealing with large-scale oil pollution, multiple cleaning ships 1 provided by the utility model can be dispatched, and their oil tanks 5 can be connected to ships with large recovery oil tanks 5 to facilitate the rapid and centralized treatment of separated oil pollution.
