Description

Technical Field

[0001] The present application relates to the field of oil separation technology, and in particular to a high-efficiency oil separation device. Background Art

[0002] Industrial production, especially in the petroleum and petrochemical industries, often produces large quantities of oily slurries. The oil in these slurries primarily exists in three states: floating oil, emulsified oil, and dissolved oil. Floating oil, due to its large particles, is relatively easy to separate from water using physical methods. Emulsified and dissolved oil, however, are more difficult to separate from water due to their smaller droplets or partial dissolution, leading to serious environmental pollution upon discharge.

[0003] Currently, the primary equipment for treating oily slurries is oil separators. Existing oil separators typically utilize the density difference between water and oil to separate and remove floating oil from the slurry through natural flotation under the influence of gravity. This removal process easily disturbs the slurry surface, and due to these level fluctuations, the separated floating oil contains a high water content. This not only reduces oil recovery efficiency but also increases the difficulty and cost of subsequent treatment. Summary of the Invention

[0004] In order to reduce the water content in oil when separating water and oil, thereby improving the oil recovery efficiency and reducing the difficulty and cost of subsequent processing, the present application provides a high-efficiency oil separation device.

[0005] The present application provides an efficient oil separation device that adopts the following technical solutions:

[0006] A high-efficiency oil separation device, comprising a primary separation mechanism, a clear liquid separation mechanism and a turbid liquid separation mechanism; the primary separation mechanism comprises a raw water pipe, a primary separation pipe and a first motor; the raw water pipe is hollowed out, and a primary separation membrane is provided on the inner wall of the raw water pipe, the membrane pores of the primary separation membrane can only allow water molecules to pass through; the primary separation pipe is sleeved outside the raw water pipe, the first motor is provided at the end of the primary separation pipe, and the first motor is used to drive the raw water pipe to rotate; the raw water pipe and the primary separation pipe are both inclined, and the height of the water outlet is lower than that of the inlet Water end; the clear liquid separation mechanism includes a sedimentation tank, which is used to hold the first clear liquid flowing out of the primary branch pipe; the turbid liquid separation mechanism includes a filter screen and a clear liquid pool, the filter screen is used to hold the turbid liquid flowing out of the primary branch pipe, the mesh of the filter screen is only for water molecules to pass through, and the clear liquid pool is used to hold the second clear liquid flowing out of the filter screen; a conveying line is provided between the clear liquid pool and the sedimentation tank, and the conveying line is used to convey the second clear liquid in the clear liquid pool to the sedimentation tank.

[0007] By adopting the above technical solution, when separating water and oil, the oil-containing raw water is first introduced into the raw water pipe, and then the first motor is started. The first motor drives the raw water pipe to rotate at high speed. During the rotation of the raw water pipe, the water molecules with higher density in the raw water pass through the primary separation membrane and the hollow raw water pipe under the action of centrifugal force and enter the gap between the primary separation pipe and the raw water pipe, forming a first clear liquid with a lower oil content, and a turbid liquid with a higher oil content remains in the raw water pipe, so as to perform preliminary separation of water and oil and remove part of the water in the raw water.

[0008] Because both the raw water pipe and the primary branch pipe are tilted, the first clear liquid in the primary branch pipe after initial separation flows under its own gravity into the sedimentation tank, where it settles before undergoing subsequent treatment. Meanwhile, the turbid liquid with a high oil content flowing from the raw water pipe flows under its own gravity onto the filter screen. Larger oil droplets remain on the filter screen, while the remaining oil flows through the filter mesh with the water into the clear liquid tank, forming the second clear liquid. Finally, a conveyor line transports the second clear liquid from the clear liquid tank to the sedimentation tank for secondary treatment. This structure achieves multi-stage separation and adopts different treatment methods for water with different oil contents, improving the effectiveness and efficiency of oil recovery and reducing the cost and difficulty of subsequent processing.

[0009] Optionally, the raw water pipe is coaxially connected to a rotating shaft, a plurality of fan blades are provided on the circumference of the rotating shaft, and the ends of the fan blades away from the rotating shaft are connected to scrapers, and the edges of the scrapers abut against the primary separation membrane.

[0010] By adopting the above technical solution, when the raw water flows in the raw water pipe, the water pressure drives the fan blades to rotate, and the fan blades stir the raw water to reduce the possibility of oil in the raw water adhering to the primary separation membrane and clogging the primary separation membrane; and in the process of rotation of the fan blades, the scraper plate is synchronously driven to move relative to the primary separation membrane, scraping off the oil attached to the primary separation membrane, further reducing the possibility of oil in the raw water adhering to the primary separation membrane and clogging the primary separation membrane.

[0011] Optionally, the clear liquid separation mechanism also includes a mounting frame and a rotating frame, and the rotating frame is rotatably connected to the mounting frame; there are multiple sedimentation tanks, and multiple sedimentation tanks are installed on the rotating frame, and multiple sedimentation tanks are arranged at intervals around the axis of rotation of the rotating frame relative to the mounting frame, and the sedimentation tanks pass under the water outlet of the primary branch pipe during the rotation of the rotating frame; multiple hinged rods are provided on the surface of the sedimentation tank facing the rotating frame, and multiple hinged rods are extended along the gravity direction of the sedimentation tank, and multiple hinged rods are arranged at intervals in the horizontal direction; one end of the hinged rod is hinged to the surface of the sedimentation tank facing the rotating frame, and the other end is hinged to the surface of the rotating frame facing the sedimentation tank.

[0012] By adopting the above technical solution, the first clear liquid flowing out of the primary branch pipe flows into the sedimentation tank below the water outlet end thereof (for the convenience of expression, the sedimentation tank will be temporarily named the first sedimentation tank in the following text, and the next sedimentation tank after the sedimentation tank that will move to the bottom of the water outlet end will be named the second sedimentation tank), forming an impact on the first sedimentation tank. The first sedimentation tank receives the first clear liquid while driving the rotating frame to rotate. During the rotation process, the second sedimentation tank gradually moves to the bottom of the water outlet end of the primary branch pipe, and begins to receive the first clear liquid while driving the rotating frame to rotate. At this time, the first clear liquid no longer impacts the first sedimentation tank, so that a relatively stable sedimentation environment is formed in the first sedimentation tank, so that the clear liquid separation mechanism can have a stable sedimentation environment while continuing to receive the first clear liquid from the primary branch pipe, thereby ensuring the oil separation efficiency.

[0013] Optionally, a hollow support plate is provided in the sedimentation tank, and the support plate divides the sedimentation tank into an upper clear liquid chamber and a lower clear water chamber; multiple layers of filter membranes are placed on the support plate, and the membrane pores of the filter membranes can only allow water molecules to pass through.

[0014] By adopting the above technical solution, after the first clear liquid enters the sedimentation tank, it first enters the clear liquid cavity and precipitates in the clear liquid cavity. During the sedimentation process, the oil floats up, and at the same time, the water in the clear liquid cavity gradually flows into the clean water cavity through the filter membrane under the action of its own gravity to form clean water; after a certain period of time, most of the oil is filtered to the top filter membrane, and the top filter membrane is removed, and then the oil attached to the filter membrane is scraped off. In this way, further water-oil separation is completed while sedimentation is taking place, and because the filter membrane is placed on the support plate, the top filter membrane can be easily removed, which makes it easy to handle and also enables the sedimentation tank to be suitable for a sedimentation tank that can rotate with the rotating frame for a long time. After all the filter membranes on the support plate are used up, filter membranes can be added to the support plate. The operation is simple and the degree of automation is high.

[0015] Optionally, the sedimentation tank is provided with a hose, and the mounting frame is provided with a clean water pipe; one end of the hose is connected to the clean water chamber, and the other end is connected to the clean water pipe; the clean water pipe is provided with a negative pressure pump, and the negative pressure pump is used to transport the clean water in the clean water chamber to the clean water pipe; the mounting frame is provided with a distillation box, and the sedimentation tank passes through the distillation chamber of the distillation box during the rotation of the rotating frame.

[0016] By adopting the above technical solution, the negative pressure pump transports the clean water in the clean water chamber to the clean water pipe, on the one hand, to empty the clean water chamber and collect the clean water; on the other hand, it reduces the weight of the sedimentation tank that has been filled with the first clear liquid to reduce the load on the hinged rod, and at the same time, it also makes the overall center of gravity of the rotating frame deviate from the center position of the rotating frame, so that the rotating frame can rotate smoothly after being impacted by the first clear liquid.

[0017] In addition, after the sediment tank enters the distillation cavity, the distillation cavity heats and distills the sediment tank, thereby distilling the moisture in the sediment tank, further reducing the water content in the oil, and improving the oil recovery effect and efficiency.

[0018] Optionally, the mounting frame is movably connected with a suction cup, and the suction cup is used to grab the uppermost filter membrane in the sediment tank leaving the distillation cavity.

[0019] By adopting the above technical solution, after the sediment tank leaves the distillation cavity, the uppermost filter membrane in the sediment tank is removed by the suction cup for subsequent separation and processing of the oil on the filter membrane, and the sediment tank can also be used for the next process of containing the first clear liquid.

[0020] Optionally, the four corners of the filter membrane are provided with rigid gaskets.

[0021] By adopting the above technical solution, on the one hand, the gaskets with a certain thickness are used to form a certain isolation between adjacent filter membranes, so that there is a certain gap between adjacent filter membranes, and when the suction cup sucks the uppermost filter membrane, the risk of the filter membranes below the filter membrane being taken away or being driven is reduced.

[0022] On the other hand, the gravity of the gasket increases the gravity of the filter membrane and the rigidity of the four corners of the filter membrane, reducing the possibility of displacement of the filter membrane under the impact of the first clear liquid.

[0023] In addition, the rigid gasket also provides a relatively flat adsorption surface for the suction cup, which facilitates the stability of the suction cup in grabbing the filter membrane.

[0024] Optionally, the gasket has magnetism.

[0025] By adopting the above technical solution, the attraction between adjacent gaskets is used to establish a connection between adjacent filter membranes, further reducing the risk of displacement of the filter membrane under the impact of the first clear liquid.

[0026] Optionally, the filter screen is made of flexible material; the turbid liquid separation mechanism comprises a plurality of first air cylinders, the plurality of first air cylinders are vertically arranged, the output ends of the plurality of first air cylinders are connected to the filter screen, and a plurality of connection points formed between the plurality of first air cylinders and the filter screen are arranged along the edges of the filter screen.

[0027] By adopting the above technical solution, the turbid liquid with a high oil content flowing out of the outlet end of the raw water pipe flows to the filter screen, and at this time, the first air cylinder is started to move up and down at different speeds at the end of the first air cylinder, thereby driving the filter screen to shake, so as to more efficiently filter the turbid liquid.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] By providing a primary separation mechanism, a clear liquid separation mechanism, and a turbid liquid separation mechanism, the primary separation mechanism is used to centrifuge raw water to separate the raw water into a turbid liquid and a clear liquid. The clear liquid is then precipitated by the clear liquid separation mechanism, and the turbid liquid is filtered by the turbid liquid separation mechanism. A second clear liquid filtered from the turbid liquid is then transported to a sedimentation tank via a conveying line for further sedimentation. Thus, the above structure forms a multi-stage separation, and different treatment methods are adopted for water with different oil contents, thereby improving the oil recovery effect and efficiency.

[0030] By dividing the sedimentation tank into a clear liquid chamber and a clear water chamber, and placing multiple layers of filter membranes in the clear liquid chamber, the water and oil in the sedimentation tank are separated during sedimentation. A distillation box is also installed on the mounting frame to distill the oil-attached filter membrane, further improving the effect and efficiency of water-oil separation and reducing the water content in the separated oil.

[0031] By setting up multiple first cylinders, the output ends of the multiple first cylinders are all connected to the edge of the filter net, and the multiple connection points formed are arranged at intervals along the edge of the filter net. The output ends of the first cylinders move up and down asynchronously to cause the filter net to shake, thereby improving the filtering effect and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0040] The embodiment of the present application discloses a high-efficiency oil separation device.

[0041] Reference Figure 1 A high-efficiency oil separation device includes a primary separation mechanism 1, a clear liquid separation mechanism 2 and a turbid liquid separation mechanism 3.

[0042] Reference Figure 1 and Figure 2 The primary separation mechanism 1 includes a raw water pipe 11, a primary separation pipe 12 and a first motor 13. The raw water pipe 11 is hollowed out, and a primary separation membrane 17 is provided on the inner wall of the raw water pipe 11. The primary separation membrane 17 is fixed to the inner wall of the raw water pipe 11 by point bonding. The membrane pores of the primary separation membrane 17 can only allow water molecules to pass through. The primary separation pipe 12 is sleeved outside the raw water pipe 11, and there is a gap between the inner wall of the primary separation pipe 12 and the outer wall of the raw water pipe 11. The first motor 13 is installed at the end of the primary separation pipe 12, and the first motor 13 is used to drive the raw water pipe 11 to rotate. The raw water pipe 11 and the primary separation pipe 12 are both inclined, and the height of the water outlet is lower than that of the water inlet. When the raw water pipe 11 rotates, water molecules with higher density pass through the primary separation membrane 17 and the raw water pipe 11 due to centrifugal force and enter the gap between the primary separation pipe 12 and the raw water pipe 11 to form a first clear liquid, while the oil with lower density remains in the raw water pipe to form a turbid liquid with a higher oil content, thereby preliminarily separating the water and oil in the raw water.

[0043] The raw water pipe 11 is coaxially connected to a rotating shaft 14. Multiple sets of blades 15 are arranged around the circumference of the rotating shaft 14. The blades 15 in each set are spaced apart along the length of the rotating shaft 14. The multiple sets of blades 15 are spaced apart along the circumference of the rotating shaft 14. After the raw water enters the raw water pipe 11, the blades rotate relative to the pipe 11 under the impact of the raw water, stirring the raw water and turbid liquid therein, reducing the possibility of oil in the raw water and turbid liquid adhering to the primary separation membrane 17 and potentially clogging it. The raw water can be introduced at high pressure.

[0044] The raw water pipe 11 is also equipped with multiple oil scrapers 16, extending along its length. The number of oil scrapers 16 is equal to the number of blades 15 groups. Each blade group 15 is connected to a single oil scraper 16 at one end away from the rotational axis 14. The blades 15 drive the oil scrapers 16 to rotate relative to the primary separation membrane 17, scraping off any oil adhering to the primary separation membrane 17. This further reduces the risk of oil clogging the primary separation membrane 17.

[0045] Reference Figure 3 and Figure 4 The clear liquid separation mechanism 2 includes a mounting frame 21, a rotating frame 22, and a settling tank 23. The rotating frame 22 is circular and rotatably connected to the mounting frame 21 at its center. A plurality of settling tanks 23 are provided, each connected to the rotating frame 22. The plurality of settling tanks 23 are arranged at equal intervals around the axis of rotation of the rotating frame 22 relative to the mounting frame 21. As the rotating frame 22 rotates, the plurality of settling tanks 23 sequentially pass below the outlet end of the primary distribution pipe 12.

[0046] A plurality of hinged rods 231 are provided on the surface of the sedimentation tank 23 facing the rotating frame 22. The plurality of hinged rods 231 are all extended along the gravity direction of the sedimentation tank 23, and the plurality of hinged rods 231 are arranged at intervals along the horizontal direction. In this embodiment, two hinged rods 231 are provided. One end of the hinged rod 231 is hinged to the surface of the sedimentation tank 23 facing the rotating frame 22, and the other end is hinged to the surface of the rotating frame 22 facing the sedimentation tank 23. As a result, the sedimentation tank 23 is always open upward and relatively stable under the action of its own gravity during the movement with the rotating frame 22. On the one hand, it is convenient for receiving the first clear liquid leaving the primary branch pipe 12. On the other hand, the first clear liquid in the sedimentation tank 23 below the water outlet end leaving the primary branch pipe 12 will no longer be impacted by the first clear liquid in the primary branch pipe 12, providing a relatively stable sedimentation environment for the first clear liquid contained in these sedimentation tanks 23, thereby ensuring the sedimentation effect.

[0047] Reference Figure 4 and Figure 5The sedimentation tank 23 is detachably connected to a hollow support plate 232 by snap-fitting. The support plate 232 divides the sedimentation tank 23 into an upper clear liquid chamber 235 and a lower clear water chamber 236. A multi-layer filter membrane 233 is placed on the support plate 232. The membrane pores of the filter membrane 233 can only allow water molecules to pass through. When the sedimentation tank 23 rotates to below the water outlet end of the primary branch pipe 12, the first clear liquid flowing out of the primary branch pipe 12 enters the clear liquid chamber 235 and precipitates in the clear liquid chamber 235. During precipitation, water molecules gradually flow into the clear water chamber 236 under the action of their own gravity, thereby performing water-oil separation during precipitation, further improving the separation efficiency.

[0048] Furthermore, the sedimentation tank 23 is provided with a hose 24, and a clean water pipe 25 is provided in the middle of the mounting frame 21. The clean water pipe 25 is connected to the clean water collection area. One end of the hose 24 is connected to the clean water chamber 236 on the surface of the sedimentation tank 23 facing the rotating frame 22, and the other end is connected to the clean water pipe 25. A negative pressure pump is provided on the peripheral side of the clean water pipe 25. The negative pressure pump is used to pump the clean water in the clean water chamber 236 into the clean water pipe 25. On the one hand, the clean water in the clean water chamber 236 is collected to facilitate the recycling of water resources. On the other hand, the clean water chamber 236 is emptied, reducing the weight of the sedimentation tank 23 already filled with the first clear liquid, thereby reducing the load on the hinged rod 231, and also allowing the rotating frame to rotate smoothly under the impact of the first clear liquid.

[0049] Mounting frame 21 is equipped with a distillation tank 27, located at the upper right corner of the mounting frame 21. Multiple sedimentation tanks 23 sequentially pass through the distillation chamber of distillation tank 27 as the rotating frame 22 rotates. After entering the distillation chamber, the distillation tank 27 heats the sedimentation tanks 23, evaporating water from the filter membranes 233. This further reduces the water content in the separated oil and improves the oil separation effect and efficiency.

[0050] Furthermore, rigid gaskets 234 are bonded and fixed to each of the four corners of the filter membrane 233. This design, on the one hand, utilizes the suction force between the multiple gaskets 234 to establish a connection between the multiple filter membranes 233, thereby securing the filter membranes 233 and reducing the possibility of displacement of the filter membranes 233 under the impact of the first clear liquid. On the other hand, the gaskets 234 of a certain thickness create a certain gap between adjacent filter membranes 233, so that when the suction cup 26 absorbs the top filter membrane 233, the filter membranes 233 below it are not moved along with it.

[0051] The gasket 234 can be made of stainless steel.

[0052] Reference Figure 3 and Figure 6The upper part of the mounting frame 21 is provided with four second air cylinders 261, and the sediment tank 23 passes below the second air cylinders 261 during rotation. The output end of the second air cylinder 261 is provided with a suction cup 26, and the four suction cups 26 corresponding to the four second air cylinders 261 correspond to the four corners of the filter membrane 233, so that the uppermost filter membrane 233 in the sediment tank 23 away from the distillation tank 27 is sucked by the second air cylinder 261 and the suction cup 26.

[0053] The mounting frame is also provided with a third air cylinder 262, and the four second air cylinders 261 are connected to the output end of the third air cylinder 262 through connecting rods, and the third air cylinder 262 is used to drive the four second air cylinders 261 to move horizontally.

[0054] The mounting frame 21 is also movably connected with a containing tank 28, and the containing tank 28 is used to contain the filter membrane 233 grabbed by the second air cylinder 261. In the embodiment, the containing tank 28 is slidably connected to the mounting frame 21 along the height direction of the mounting frame 21, and the mounting frame 21 is provided with a fourth air cylinder 211, and the fourth air cylinder 211 is used to drive the containing tank 28 to move relative to the mounting frame 21.

[0055] The turbid liquid separation mechanism 3 includes a filter screen 31, a clear liquid pool 32, and a first air cylinder 33. The filter screen 31 is used to receive the turbid liquid flowing out of the primary separation pipe 12, and the mesh of the filter screen 31 only allows water molecules to pass through. The clear liquid pool 32 is used to receive the second clear liquid flowing out of the filter screen 31. The clear liquid pool 32 and the sediment tank 23 are provided with a conveying line 4, and the conveying line 4 is used to convey the second clear liquid in the clear liquid pool 32 to the sediment tank 23.

[0056] In the embodiment, the filter screen 31 is made of flexible material. The first air cylinder 33 is provided in plurality, and the plurality of first air cylinders 33 are vertically arranged. The output end of the plurality of first air cylinders 33 is connected to the filter screen 31, and a plurality of connection points formed between the plurality of first air cylinders and the filter screen 31 are arranged along the edges of the filter screen 31.

[0057] It can be understood that the filter screen 31 and the first air cylinder 33 are detachably connected to facilitate replacement and cleaning of the filter screen 31. The detachable structure can be a quick release structure matched at the end of the filter screen 31 and the first air cylinder 33, or can be realized by binding.

[0058] Back to Figure 1 In the embodiment, the conveying line 4 includes a conveying pipe 41 and a conveying pump 42. One end of the conveying pipe 41 is fixedly connected to the water outlet end of the primary separation pipe 12, and the other end is communicated with the clear liquid pool 32. The conveying pump 42 is fixed to the side of the conveying pipe 41, and the conveying pump 42 is used to pump the second clear liquid in the clear liquid pool 32 to the position where the water outlet end of the primary separation pipe 12 is located, so as to flow into the sediment tank 23 for further sedimentation treatment.

[0059] The working principle of a high-efficiency oil-separation device according to the embodiment is as follows: raw water is first introduced into the raw water pipe 11, and the first motor 13 is activated, which drives the raw water pipe 11 to rotate at high speed. During the rotation, the denser water molecules, due to centrifugal force, pass through the hollow raw water pipe 11 and the primary separation membrane 17 and enter the gap between the raw water pipe 11 and the primary separation pipe 12, forming a first clear liquid.

[0060] At the outlet end of the primary branch pipe 12, the first clear liquid flows into the sedimentation tank 23 below the outlet end under the action of gravity. Under the impact of the first clear liquid, the sedimentation tank 23 continues to receive the first clear liquid while driving the rotating frame 22 to rotate until the next sedimentation tank 23 moves to the bottom of the outlet end.

[0061] After exiting the outlet, the sedimentation tank 23, containing the first clear liquid, enters sedimentation mode. Under the influence of gravity, water molecules in the clear liquid chamber 235 pass through the filter membrane 233 and enter the clear water chamber 236 below, leaving the oil trapped on the filter membrane 233. (Note that during this process, the impact force of the first clear liquid, and thus the rotation speed of the rotating frame 22, can be adjusted by adjusting the height or inclination of the primary branch pipe 12; the impact force of the first clear liquid can also be adjusted by providing a delivery pump on the water pipe connected to the outlet end of the primary branch pipe 12.) The sedimentation tank 23 then continues to rotate and enters the distillation chamber of the distillation tank 27 for distillation. After exiting the distillation tank 27, the sedimentation tank 23 moves below the second cylinder 261. The second cylinder 261, via the suction cup 26 at its end, draws the filter membrane 233 from the top layer of the sedimentation tank 23 and carries it to the storage tank 28 for collection. The filter membrane 233 in the storage tank 28 can then be removed for further processing.

[0062] At the outlet of the raw water pipe 11, turbid liquid flows from the raw water pipe 11 onto the filter 31. At this point, the first cylinder 33 is activated, and the ends of the multiple first cylinders 33 move asynchronously. This causes the filter 31 to shake, filtering the turbid liquid. The filtered water flows through the filter 31 into the clear liquid pool 32 below, forming the second clear liquid. When oil accumulates to a certain level on the filter 31, it is replaced by scraping the oil off the replaced filter 31 for collection.

[0063] The second clear liquid is transported to the sedimentation tank 23 via the transport line 4 to undergo the above-mentioned sedimentation treatment.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
