Description

Technical Field

[0001] The present invention relates to the technical field of floating oil collection, and more specifically, to a floating oil collection device. Background Art

[0002] Crude oil is an important fossil fuel, mainly formed by the geological action of ancient marine organisms buried underground over millions of years. Its main components include hydrocarbons (such as alkanes, cycloalkanes, and aromatic hydrocarbons), as well as a small amount of organic compounds containing sulfur, nitrogen, and oxygen and metal impurities. The properties of crude oil vary depending on the origin, and it is usually classified into light, medium, and heavy crude oil according to the API gravity. The extraction and processing of crude oil involve multiple links such as drilling, transportation, and refining. Among them, the refining process produces petroleum products such as gasoline, diesel, and aviation fuel through processes such as distillation, cracking, and reforming. However, the extraction and use of crude oil also bring problems such as environmental pollution and greenhouse gas emissions, which have prompted the exploration of clean energy and sustainable technologies globally.

[0003] However, during the extraction, transportation, storage, or use process, due to pipeline ruptures, oil tanker accidents, offshore drilling platform failures, or human operation errors, crude oil is accidentally released into the water environment, which will cause serious damage to the ecosystem, such as polluting water bodies, endangering marine organisms, and destroying coastal wetlands. In addition, the toxic components in crude oil (such as benzene, polycyclic aromatic hydrocarbons, etc.) may remain for a long time, threatening human health.

[0004] In the related technologies, the technologies for dealing with crude oil spills include physical methods (such as oil booms, adsorption materials), chemical methods (such as dispersants), and biological methods (such as microbial degradation). Chemical methods and biological methods are not applicable to large-scale spills due to high costs, and they will have certain side effects on the environment and cannot meet the environmental protection requirements, so they cannot be widely promoted. Among the physical methods, membrane filtration separation and porous material adsorption are commonly used. However, when collecting high-viscosity crude oil, due to the large viscous resistance of the crude oil, it will adhere to the membrane surface or inside the porous material, seriously affecting the collection efficiency. Therefore, how to optimize the collection technology of high-viscosity crude oil and improve the collection efficiency has become an urgent technical problem to be solved. Summary of the Invention

In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present invention.

[0043] The terms used herein are merely for describing specific embodiments and are not intended to limit the present invention. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0046] Figure 1 is a three-dimensional structural view of the floating oil collection device provided by the exemplary embodiment of the present invention, Figure 2 is a three-dimensional structural view of the floating oil collection device from another perspective provided by the exemplary embodiment of the present invention, with some oil lifting members removed, Figure 3 is a schematic plan view of the floating oil collection device provided by the exemplary embodiment of the present invention.

[0047] The exemplary embodiment of the present invention provides a floating oil collection device, as Figures 1 to 3 shown, including a working platform floating on the water surface, and further including a driving part 1, an oil lifting part 2, a vibrating part 3, and an oil storage part 4. The driving part 1 is installed on the working platform, and the support shaft 11 of the driving part 1 is parallel to the water surface. The oil lifting part 2 includes a plurality of oil lifting members 21 arranged at intervals in the circumferential direction of the support shaft 11. The oil lifting part 2 is configured to rotate under the drive of the support shaft 11, so that the plurality of oil lifting members 21 are successively immersed in the water to adhere to the floating oil, so as to bring the floating oil away from the water surface. The vibrating part 3 is configured to apply vibration to the oil lifting members 21 adhering to the floating oil to promote the floating oil to fall off. The oil storage part 4 is adapted to receive the floating oil falling off from the oil lifting members 21.

[0048] When a crude oil leakage accident occurs, the floating oil on the water surface should be cleaned and collected as soon as possible to minimize the pollution of the water body by the crude oil as much as possible. Traditional methods are often difficult to effectively collect high-viscosity crude oil (the viscosity is usually greater than 5000 mPa·s). Therefore, in this embodiment, the oil lifting members 21 utilize the viscosity difference between the floating oil and water to selectively adhere to the floating oil. At the same time, a plurality of oil lifting members 21 are configured to rotate with the oil lifting part 2. The plurality of oil lifting members 21 are successively immersed in the water to adhere to the floating oil, and after adhesion, through the vibration of the vibrating part 3, a periodic shear force is generated to break the network structure between oil molecules, reduce the viscosity, and make the floating oil fall off from the oil lifting members 21 into the oil storage part 4. In this way, it is possible to achieve efficient and continuous collection of the floating oil on the water surface, with low use cost and high safety and reliability.

[0049] In an exemplary embodiment, asFigures 2 - 3 As shown, the oil extraction part 2 further includes two mounting brackets 22, which are arranged at intervals along the axial direction and are configured to rotate synchronously under the drive of the support shaft 11, and the oil extraction member 21 is arranged between the two mounting brackets 22.

[0050] In such an embodiment, by setting the two mounting brackets 22 to rotate synchronously, the stability of the device is improved. While the two mounting brackets 22 rotate synchronously, multiple oil extraction members 21 are successively immersed in the water and then leave the water surface after adhering to the floating oil. When the oil extraction member 21 rotates with the mounting bracket 22 to the lowest point, at least 1 / 2 of its part is immersed in the water to ensure the oil extraction efficiency.

[0051] According to an embodiment of the present disclosure, as Figure 3 shown, each oil extraction member 21 includes a first rod 211 and a plurality of second rods 212. The first rod 211 extends parallel to the axial direction and is rotatably installed between the outer peripheries of the two mounting brackets 22. The plurality of second rods 212 are arranged on the first rod 211 in the radial direction. The second rods 212 rotate with the support shaft 11 and, based on the action of gravity, switch between a first state in which they are radially away from the axis of the support shaft 11 in the axial direction and a second state in which they are radially close to the axis. The second rods 212 are adapted to adhere to the floating oil by utilizing the viscosity difference between the floating oil and water in the first state.

[0052] In such an embodiment, the two ends of the first rod 211 are respectively rotatably connected to the two mounting brackets 22. While realizing the synchronous rotation of the two mounting brackets 22, it also enables the oil extraction member 21 to rotate relative to the mounting bracket 22, that is, the oil extraction member 21 rotates around the support shaft 11 while revolving. Specifically, the rotation of the oil extraction member 21 is achieved by gravity. During the revolution process, the second rods 212 are always in a natural hanging state. Or rather, the first end of the second rod 212 is connected to the first rod 211, and in the vertical direction, the second end of the second rod 212 is always directly below the first end. When the second rod 212 is in the first state, it is radially away from the axis of the support shaft 11 to adhere to the floating oil. When the second rod 212 is in the second state, it is radially close to the axis of the support shaft 11 to receive the vibration from the vibration part 3. In addition, using a plurality of second rods 212 for floating oil adhesion increases the contact area between the oil extraction member 21 and the floating oil, and at the same time can also reduce the resistance when the oil extraction member 21 moves in the water.

[0053] Exemplarily, the two ends of the first rod 211 are connected to the mounting bracket 22 through bearings to achieve relative rotation with the mounting bracket 22.

[0054] Exemplarily, the second rod 212 is configured as a cylindrical shape to further increase the contact area with the floating oil and reduce the water flow resistance.

[0055] Further according to an embodiment of the present disclosure, as Figure 2As shown, each mounting bracket 22 includes a turntable 221 and a plurality of support rods 222. The turntable 221 is rotatably mounted on the support shaft 11, and the plurality of support rods 222 radially extend outward from the outer edge of the turntable 221 at equal intervals. Both ends of each first rod 211 are respectively rotatably connected between two facing support rods 222.

[0056] In such an embodiment, the turntable 221 is composed of an annular frame and a plurality of radially arranged spokes to form a hub-like structure, which reduces the weight as much as possible under the premise of meeting the structural strength requirements and reduces the load on the driving part 1. The support rods 222 radially extend outward from the outer edge of the turntable 221 and are used for rotatably mounting the first rods 211.

[0057] Optionally, the spokes of the turntable 221 and the support rods 222 are arranged staggeredly in the circumferential direction to avoid too concentrated stress distribution on the mounting bracket 22 and extend the service life.

[0058] In some other embodiments, the lengths of two adjacent second rods 212 are different, and the second ends of the second rods 212 are arranged in a substantially sinusoidal or cosine curve. In this way, irregular vortices can be generated in the water body when moving in the water, breaking the continuity of the oil layer, and at the same time, the oil layers at multiple depths can be adhered to, reducing the possibility of missed capture.

[0059] In an exemplary embodiment, the second rod 212 is made of stainless steel.

[0060] In such an embodiment, stainless steel has good corrosion resistance, is easy to clean on the surface, has a long service life, and has high strength and stiffness, and is not easily deformed or damaged.

[0061] In an exemplary embodiment, as Figure 2 shown, the vibration part 3 includes a resonance unit 31 and a vibration conduction plate 32. The resonance unit 31 is configured to generate vibration in the energized state. The vibration conduction plate 32 is located at the highest point of the rotation trajectory of the oil extraction part 2, is connected to the resonance unit 31, and is configured to sequentially transmit the vibration generated by the resonance unit 31 to one or two oil extraction members 21 passing through the vibration conduction plate 32, so that the floating oil adhering to one or two oil extraction members 21 drops into the oil storage part 4.

[0062] In such an embodiment, the resonance unit 31 can be directly mounted on the working platform. The height of the resonance unit 31 is approximately flush with the highest point of the rotation trajectory of the oil extraction part 2, and the vibration is transmitted to the oil extraction member 21 through the vibration conduction plate 32.

[0063] More specifically, the vibration conduction plate 32 transmits vibration through the support rod 222 connected to the oil extraction member 21 in contact, so as to minimize the influence of vibration on the remaining oil extraction members 21, especially the oil extraction members 21 close to or immersed in the water surface, and ensure the oil extraction efficiency.

[0064] The resonance unit 31 is composed of an energy converter, a signal amplifier, and a signal generator. The signal generator generates and emits a signal, the signal amplifier receives the signal and transmits it to the energy converter, and the electrical signal is converted into mechanical vibration through the energy converter. Exemplarily, the resonance unit 31 includes but is not limited to using a resonance horn, and the vibration frequency is preferably 25w.

[0065] Optionally, the number of the support rods 222 is preferably 6. Correspondingly, the number of the oil lifting members 21 is also 6. On the premise of ensuring the continuity of oil lifting, it is avoided that the oil lifting members 21 are arranged too densely, which may affect the oil lifting efficiency due to vibration.

[0066] In some other embodiments, the frequency and amplitude of the resonance unit 31 are adjusted according to the viscosity of the floating oil. For example, for heavy oil (viscosity usually greater than 100 mPa·s), a low frequency and large amplitude are preferred, and for light oil (viscosity usually less than 10 mPa·s), a high frequency and small amplitude are preferred.

[0067] In an exemplary embodiment, as Figure 1 and Figure 3 shown, the driving part 1 includes two support seats 12 and a motor 13. The two support seats 12 are arranged on the working platform and face each other. The support shaft 11 includes a driving shaft 111 and a fixed shaft 112 that are coaxially installed on the two support seats 12 respectively. The motor is installed on one of the two support seats 12 and is adapted to drive the active frame among the two mounting frames 22 to rotate through the driving shaft 111, so that the active frame drives the driven frame among the two mounting frames 22 to rotate around the fixed shaft 112 through the first rod 211.

[0068] In such an embodiment, the motor 13 is installed on the first support seat among the two support seats 12, and transmits the torque to the driving shaft 111 through gear transmission. The driving shaft 111 drives the active frame to rotate, and the active frame drives the driven frame to rotate synchronously through the first rod 211. Specifically, the driven frame is installed on the fixed shaft 112 through a bearing to achieve relative rotation with the fixed shaft.

[0069] Optionally, two motors 13 can also be set to drive the mounting frame 22 to rotate respectively, but it is necessary to control the same rotation speed and the same start and stop time, or set one motor 13 to drive the two mounting frames 22 simultaneously through transmission methods such as gear transmission.

[0070] Optionally, the resonance unit 31 is installed on the support seat 12 close to the driven frame.

[0071] In an exemplary embodiment, as Figure 1As shown, the oil storage part 4 includes a first oil storage container 41, which is located between two mounting brackets 22 and is rotatably mounted on the support shaft 11 through bearings, so that the opening of the first oil storage container 41 remains upward.

[0072] In such an embodiment, the first oil storage container 41 is generally located at the center of the mounting bracket 22. One end of the first oil storage container 41 is mounted on the drive shaft 111 through a bearing, and the other end includes but is not limited to being mounted on the fixed shaft 112 through a bearing, so that the opening of the first oil storage container 41 always faces upward to receive the floating oil dripping from the oil lifting member 21.

[0073] More specifically, the first oil storage container 41 is configured as a semi-cylindrical shell, and the axis of the cylinder substantially coincides with the axis of the support shaft 11, so that the first oil storage container 41 can keep its opening facing upward under the action of gravity.

[0074] According to an embodiment of the present disclosure, as Figure 3 shown, the oil storage part 4 further includes an oil pump 42 and a second oil storage container 43. The oil pump 42 is arranged on the working platform and is configured to extract the floating oil in the first oil storage container 41 through a pipeline 421. The second oil storage container 43 is connected to the oil outlet of the oil pump 42 to store the collected floating oil.

[0075] In such an embodiment, due to space limitations in the layout, the capacity of the first oil storage container 41 is limited. The floating oil in the first oil storage container 41 is pumped to the second oil storage container 43 for storage through the oil pump 42, realizing continuous collection of the floating oil on the water surface and improving the collection efficiency.

[0076] Further according to an embodiment of the present disclosure, as Figure 3 shown, the pipeline 421 is configured to axially pass through the fixed shaft 112.

[0077] In such an embodiment, while the two mounting brackets 22 rotate synchronously, the multiple oil lifting members 21 also rotate accordingly. By passing the pipeline 421 through the fixed shaft 112, interference of the pipeline 421 with the rotation of the mounting brackets 22 and the oil lifting members 21 is avoided, enabling the floating oil in the first oil storage container 41 to be pumped out without stopping the oil lifting part 2, further improving the collection efficiency.
