Description

Technical Field

[0001] This invention relates to the field of environmental governance technology, and more particularly to a device for recovering crude oil from the sea surface that can achieve water-oil separation. Background Technology

[0002] With the increasing prominence of environmental issues and the growing tension in energy supply, spilled crude oil recovery, as a direct method of environmental purification, has received increasing attention from countries worldwide. However, traditional marine surface cleaning methods have certain limitations. They are constantly affected by factors such as weather and location, and cannot always meet environmental protection needs. Geographically, areas far from the coastline are almost inaccessible by small numbers of drivers, making it difficult to meet safety requirements. In terms of scale, traditional methods require a large amount of manpower and resources, which is not economical. To address this, a marine surface oil-water separation and recovery device has been proposed. This device features a bottom-mounted annular inclined spiral column, which provides better water pumping performance compared to traditional oil-water pumps. Furthermore, it effectively increases the suction capacity of the oil-water mixture and incorporates grooves to prevent crude oil or solid matter from adhering and clogging. A tilting counterweight ring allows for timely adjustment of the direction, improving the device's efficiency and durability. It can also be used to clean oil spills even in areas with high levels of impurities on the marine surface, achieving both economic and environmental benefits.

[0003] Current traditional oil recovery technologies suffer from drawbacks such as poor oil removal efficiency, low recovery rate, and high resource consumption. In situations far from the coast or with inclement weather, oil recovery efficiency is even lower, and the viscosity of crude oil is also harmful to recovery equipment. Furthermore, some large-scale purification systems can only be fixed to large vessels and cannot rotate freely to adapt to smaller areas of pollution, resulting in inefficient oil removal and the tendency for small oil slicks to remain. Therefore, existing technologies have significant limitations in terms of application scope and effectiveness.

[0004] Therefore, it is necessary to design a crude oil recovery device that can achieve water-oil separation. Summary of the Invention

[0005] To address the limitations of existing oil removal technologies, which have limited applicability and ineffectiveness, this invention provides a marine crude oil recovery device capable of separating oil and water. The invention primarily utilizes an integrated power system in conjunction with oil suction and oil separation modules to increase the oil removal range and enhance the oil removal effect.

[0006] The technical means employed in this invention are as follows:

[0007] A marine crude oil recovery device capable of separating oil and water is characterized by comprising: a main body, an oil suction system, a propulsion system, and a control system. The oil suction system includes an oil extraction module and a separation module. The oil extraction module includes an oil pump and an oil guide pipe, with the oil guide pipe located at the lower end of the main body and connected to the oil pump. The separation module includes a centrifuge, a filter layer, and an oil storage tank. The centrifuge is connected to the oil pump, and the oil storage tank and the centrifuge are connected via the filter layer. The propulsion system includes a counterweight ring and a thruster. The counterweight ring is located on the outside of the main body, and the thruster is located at the lower end of the main body. The control system is electrically connected to the oil pump, the centrifuge, the counterweight ring, and the thruster.

[0008] Furthermore, the oil guide tube is a spiral tube, the outer periphery of the spiral tube is provided with a spiral wide groove, and the inlet of the spiral tube is provided with a spiral filter screen.

[0009] Furthermore, the centrifuge is equipped with a flow-slowing grid; the centrifuge blades have a heating function.

[0010] Furthermore, the main body of the device is equipped with an oil stain detection sensor, which is mounted on the motor tower of the main body of the device.

[0011] Furthermore, the counterweight ring is an annular water tank with a press, and the propeller is a micro propeller. The propeller can be tilted in conjunction with the counterweight ring to move the propulsion device.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The present invention provides a marine crude oil recovery device that can realize water-oil separation. It utilizes an integrated power system in conjunction with an oil suction and oil-sludge separation module to increase the oil removal range and enhance the oil removal effect.

[0014] 2. This invention provides a marine crude oil recovery device capable of separating oil and water. The liquid suction device is configured with a spiral-shaped water guide channel, which increases suction force at the liquid inlet and prevents solid deposition. Internally, it increases air velocity, and a centrifuge is installed above the liquid surface counterweight zone. This configuration effectively separates crude oil and seawater, and the device height can be stabilized by controlling the increase or decrease of the seawater counterweight, reducing energy consumption for height control. Unlike traditional processing technologies, this device achieves high efficiency and preliminary oil removal while reducing space and manual operation. Furthermore, the inclusion of oil spill detection sensors and a rotating connection device allows for timely adjustment of the counterweight tilt angle, ensuring it is always positioned for optimal oil spill handling. The device height is also automatically adjusted promptly when the oil spill thickness changes.

[0015] Based on the above reasons, this invention can be widely promoted in fields such as environmental governance technology. Attached Figure Description

[0026] like Figure 1As shown, this invention provides a marine crude oil recovery device capable of separating oil and water, comprising: a main body, an oil suction system, a propulsion system, and a control system 10. The oil suction system includes an oil extraction module and a separation module. The oil extraction module includes an oil pump 3 and an oil guide pipe, the oil guide pipe being disposed at the lower end of the main body and connected to the oil pump 3. The separation module includes a centrifuge 5, a filter layer 6, and an oil storage tank 9. The centrifuge 5 is connected to the oil pump 3, and the oil storage tank 9 and the centrifuge 5 are connected through the filter layer 6. The propulsion system includes a counterweight ring 2 and a thruster 7. The counterweight ring 2 is disposed on the outside of the main body, and the thruster 7 is disposed on the outside of the main body. The lower end of the main body of the device; the control system 10 is electrically connected to the oil pump 3, the centrifuge 5, the counterweight ring 2 and the propeller 7; the oil guide pipe is a spiral tube 1, the outer periphery of the spiral tube 1 is provided with a spiral wide groove, and the inlet of the spiral tube 1 is provided with a spiral filter screen; the centrifuge 5 is provided with a slow-flow grid; the blades of the centrifuge 5 have a heating function; the main body of the device is provided with an oil stain detection sensor, which is set on the motor tower of the main body of the device; the counterweight ring 2 is an annular water tank with a press, and the propeller 7 is a micro propeller, which can cooperate with the counterweight ring 2 to tilt and move the device.

[0027] Example 1

[0028] like Figure 1 As shown, this invention provides a marine crude oil recovery device capable of separating water and oil, comprising: a spiral tube 1, a centrifuge 5, an oil pump 3, a rotatable counterweight ring 2, a propeller 7, a battery 8, a flow-regulating grid, and an oil spill detection sensor; the spiral tube 1 is a guide tube with a wide spiral groove on its outer periphery, which can quickly suck in the seawater-crude oil mixture under high-speed rotation, and is assembled in a trapezoidal suction hole; the rotatable counterweight ring 2 is an annular water tank with a pressure machine, and its height can be controlled by controlling the amount of water, and its forward direction can be controlled by controlling the angle; the propeller 7 is a finely adjustable propeller located at the bottom center; it can tilt with the counterweight ring 2 to achieve the function of propelling the device to move and rotating in place. The oil guide pipe inlet is equipped with a spiral filter screen to filter solids during liquid collection without causing blockage; the centrifuge 5 has an acceleration device located at the center of the centrifuge container, a pressurized drainage device 4, and heated blades; the slow-flow grid is located inside the centrifuge 5, hidden during centrifugation and extended after centrifugation to rapidly decelerate the liquid, thus quickly causing stratification; the oil stain detection sensor is mounted on the motor tower, and the electrical signal circuit of the oil stain detection sensor is connected to the control circuit of the steering system.

[0029] This device uses an oil stain detection sensor to determine the location of the oil stain and feeds the signal back to the control system 10. The control system 10 adjusts the angle of the water-filled counterweight area by tilting the device and drives the propeller 7 to ensure that the device moves precisely to the oil-contaminated area and that the device height is just right to suck in the oil stain. After the oil stain is sucked into the pipeline through the high-speed rotating spiral tube 1, the liquid is separated by a centrifuge 5. An oil pump 3 is used to pressurize and accelerate the oil stain. At the same time, after the centrifuge 5 has been working, a portion of the water separated by centrifugation is injected into the counterweight area, and the excess water can be directly discharged from the device.

[0030] In summary, this invention configures the liquid suction device with a spiral-shaped water guide channel. This increases suction force at the liquid inlet and prevents solid deposition. Internally, it increases air velocity, and a centrifuge 5 is installed above the liquid surface counterweight zone. This configuration effectively separates crude oil and seawater, and the device height can be stabilized by controlling the increase or decrease of the seawater counterweight, reducing energy consumption for height control. Unlike traditional treatment technologies, this device achieves high efficiency and preliminary oil removal while reducing space and manual operation. Furthermore, the inclusion of an oil stain detection sensor and a rotating connection device allows for timely adjustment of the counterweight tilt angle, ensuring it is always positioned for optimal oil stain removal. The device height is also automatically adjusted promptly when the oil stain thickness changes.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
