Description

Technical Field

[0001] This invention belongs to the field of hydrocyclone technology, specifically relating to a sand removal and descaling device. Background Technology

[0002] Hydrocyclones are common devices used for solid-liquid separation and are widely applied in various fields such as chemical engineering and oil extraction. For example, in oil extraction, hydrocyclones are frequently used to process downhole fluids. Downhole fluids typically refer to fluids produced from formations in oil and gas wells, which may contain impurities such as silt and solid particles. During long-term production, these impurities can cause severe wear and tear on wellhead equipment, pipelines, and oil-gas separators. Furthermore, the accumulation of impurities can lead to decreased or halted production from oil and gas wells, increasing production and maintenance costs. Common hydrocyclone equipment has limited separation efficiency, which is insufficient to meet the requirements of high-efficiency production. Additionally, due to the long-term transport of liquids containing impurities, scaling can occur on the inner walls of the hydrocyclone pipes, further reducing the equipment's separation efficiency.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] See Figure 1 This application provides a sand removal and descaling device, including multiple swirling components 1 connected in series. Among the multiple swirling components 1, the inlet channel of the first swirling component 1 is provided with a terahertz quantum ring 2.

[0022] The cyclone assembly 1 is a component that achieves solid-liquid separation by using centrifugal force generated by high-speed rotation. There are mature products of the cyclone assembly 1 in the prior art, and its structure and working principle are well known to those skilled in the art. Those skilled in the art can choose the appropriate one according to their needs.

[0023] Multiple cyclone components 1 are connected in series to form a multi-stage filtration structure, which allows the input fluid to be filtered through multiple cyclone components 1 in sequence, thereby improving the solid-liquid separation efficiency.

[0024] An adjustment device can be installed between adjacent cyclone components 1 to ensure that the hydraulic pressure and velocity of the fluid entering the next stage of filtration meet the requirements. The adjustment device can be a suitable product selected from the existing technology.

[0025] The structure and working principle of the terahertz quantum ring 2 are well known to those skilled in the art. In summary, the terahertz quantum ring 2 injects terahertz waves of a specific frequency into the fluid using quantum physics technology, which diffuse with the fluid to dissolve the hard scale formed in the pipe and reduce the risk of blockage of the inner wall of the channel connecting the vortex component 1 due to scale buildup when transporting fluids containing impurities for a long time.

[0026] By placing the terahertz quantum ring 2 at the inlet of the first swirling component 1, the terahertz wave diffuses with the fluid to the next-level swirling component 1, reducing the risk of blockage in the pipe structure of this device.

[0027] See Figure 1 In some embodiments, a collection chamber 3 is also included, and the bottom outlets of the plurality of swirling components 1 are connected to the collection chamber 3.

[0028] The collection chamber 3 is used to collect the solids discharged from the swirling assembly 1.

[0029] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, a cleaning assembly 4 is provided within the collection chamber 3. The cleaning assembly 4 includes a receiving channel 43, a moving part 41, and a retractable component 44. A notch is provided at the top of the receiving channel 43, and the moving part 41 is disposed within the receiving channel 43. The retractable component 44 includes a sliding part assembly, support rods 442, and a flexible filter screen 441. The sliding part assembly includes two sliding parts 443 slidably connected to the moving part 41 along its circumference. Multiple sliding part assemblies are spaced apart along the axial direction of the receiving channel 43. Support rods 442 are disposed corresponding to the sliding parts 443 and are rotatably connected to the sliding parts 443. The rotation axis of the support rods 442 is perpendicular to the axial direction of the receiving channel 43. The flexible filter screen 441 is connected to multiple support rods 442.

[0030] The movable part 41 may be a long axis structure adapted to the shape of the receiving channel 43.

[0031] The movable part 41 is disposed in the receiving channel 43 and can move along the axial direction of the receiving channel 43.

[0032] The notch can be located at the top of the receiving channel 43.

[0033] Two sliding parts 443 of a sliding part assembly are respectively disposed on both sides of the moving part 41 in a direction perpendicular to the axial direction of the receiving channel 43, and the two sliding parts 443 can be closed or separated.

[0034] The collecting chamber 3 includes a first sidewall 31 and a second sidewall 32 disposed opposite to each other. The first sidewall 31 is provided with an opening, and the moving part 41 enters the collecting chamber 3 through the opening of the first sidewall 31. In the initial state, the support rod 442 is close to the second sidewall 32 and away from the first sidewall 31. That is, in the initial state, the angle between the support rod 442 and the receiving channel 43 is less than 90°, and the support rod 442 is in a retracted state.

[0035] Furthermore, in the initial state, the two sliding parts 443 of the sliding part assembly are in a closed state, with the two sliding parts 443 facing the gap of the receiving channel 43. In this way, the moving part 41 is in a retracted state and can be completely inside the receiving channel 43.

[0036] When the two sliding parts 443 separate and the two support rods 442 rotate in a direction perpendicular to the axis of the receiving channel 43, the flexible filter screen 441 can be opened. By combining multiple sliding parts, the flexible filter screen 441 can be opened as a whole. The flexible filter screen 441 can be set below the connection between the vortex assembly 1 and the collection chamber 3, so that the solids discharged from the vortex assembly 1 can fall on the flexible filter screen 441, while the fluid discharged with the solids can pass through the flexible filter screen 441 and collect in the collection chamber 3.

[0037] When the flexible filter screen 441 is opened, the support rod 442 can be rotated first, causing it to rotate out of the notch and into the receiving channel 43. Then, the two sliding parts 443 of the sliding part assembly separate, allowing the moving part 41 to be lifted as a whole. This allows the flexible filter screen 441 to be positioned as close as possible to the connection between the vortex assembly and the collection chamber 3, reducing the risk of solids bouncing when falling onto the flexible filter screen 441. On the other hand, if the moving part 41 is completely supported by the receiving channel 43, the fluid separated from the flexible filter screen 441 will obstruct the fluid flow, hindering its discharge from the receiving channel 43 into the collection chamber 3. By lifting the moving part 41, it is suspended in the air, preventing it from obstructing the fluid flow.

[0038] When it is necessary to clean the solids in the collection chamber 3, rotate the support rod 442 toward the second side wall 32 and close the two sliding parts 443 at the same time. At this time, the two sides of the flexible filter screen 441 are closed, reducing the risk of solids falling from the flexible filter screen 441. Then the moving part 41 can be pulled out of the collection chamber 3.

[0039] When the support rod 442 is stored, the flexible filter screen 441 tends to move towards the second side wall 32 as the support rod 442 rotates towards the second side wall 32. That is, when the moving part 41 moves towards the first side wall 31, as the support rod 442 rotates towards the second side wall 32, the flexible filter screen 441 remains in the direction of the connection between the vortex assembly 1 and the collection chamber 3 for a short period of time. This allows the flexible filter screen 441 to still be able to receive solids, reducing the risk that the solids remaining in the vortex assembly 1 will fall directly into the flexible filter screen 441.

[0040] Even if some solids accidentally fall out of the flexible filter screen 441, the solids will fall into the receiving channel 43. When the moving part 41 moves, the moving part 41 can scrape the solids and move them towards the end of the receiving channel 43.

[0041] See Figure 6 and Figure 7 In some embodiments, the moving part 41 is a hollow structure, the sliding part 443 is disposed outside the moving part 41, the peripheral wall of the moving part 41 is provided with a strip groove 411, the sliding part 443 is provided with a mating part 445, the mating part 445 passes through the strip groove 411, and the side of the mating part 445 disposed inside the moving part 41 is connected to a limiting part 444.

[0042] Neither the sliding part 443 nor the limiting part 444 can pass through the strip groove 411, so that the mating part 445 can move along the strip groove 411, and thus the sliding part 443 can move relative to the moving part 41.

[0043] See Figure 6 In some embodiments, the periphery of the receiving channel 43 is provided with water-permeable holes.

[0044] The perforated holes in the receiving channel 43 allow the fluid entering the receiving channel 43 to pass through the perforated holes and collect at the bottom of the collecting chamber 3.

[0045] The bottom of the collecting chamber 3 may be provided with an outlet 34 to discharge fluid.

[0046] See Figure 1 , Figure 4 and Figure 5In some embodiments, along the axial direction of the receiving channel 43, the collecting cavity 3 includes a first sidewall 31 and a second sidewall 32 disposed opposite to each other. The first sidewall 31 is provided with an opening. The cleaning assembly 4 also includes a driving member 42, which is movably connected to the moving part 41 along the axial direction of the receiving channel 43. An elastic element is provided between the driving member 42 and the moving part 41. The driving member 42 includes a squeezing part 421 and a pushing part 422. The driving member 42 is configured to abut against the second sidewall 32 when the moving part 41 moves from the first sidewall 31 to the second sidewall 32. The squeezing part 421 is inserted between the two sliding parts 443 of the sliding part assembly. The pushing part 422 pushes the support rod 442 to rotate away from the second sidewall 32.

[0047] The opening in the first sidewall 31 allows the movable part 41 to enter and exit the collection chamber 3.

[0048] The elastic element can be a spring.

[0049] Along the axial direction of the receiving channel 43, the driving member 42 can protrude from the moving part 41, such that when the moving part 41 moves toward the second side wall 32, the driving member 42 first abuts against the second side wall 32.

[0050] When the moving part 41 is inserted into the receiving channel 43 from the opening and moves toward the second side wall 32, the driving part 42 can abut against the second side wall 32. At this time, if the moving part 41 is pushed to move, the squeezing part 421 can push the support rod 442 to rotate, and the pushing part 422 can be inserted between the two sliding parts 443.

[0051] The position and shape of the squeezing part 421 and the pushing part 422 can be set as needed. For example, as mentioned above, when the flexible filter screen 441 is opened, the support rod 442 can be opened first, and then the sliding part 443 can move. Then the end of the squeezing part 421 inserted between the two sliding parts 443 can be pointed, so that the pushing part 422 first pushes the support rod 442 to move, and then the squeezing part 421 is inserted between the two sliding parts 443, so that the two sliding parts 443 are separated.

[0052] See Figure 1 In some embodiments, the first sidewall 31 is provided with a cover 33 for closing the opening, and the cover 33 abuts against the movable part 41 when configured to close the opening.

[0053] The cover 33 abuts against the movable part 41, so that the cover 33 can limit the movable part 41. On the other hand, when the cover 33 is opened, the movable part 41 tends to move out of the collection cavity 3 under the action of the elastic member, making it easy to pull out the movable part 41.

[0054] See Figure 3 and Figure 6In some embodiments, the moving part 41 is provided with a positioning hole, the axis of which is perpendicular to the axis of the receiving channel 43, and the collecting cavity 3 is provided with an insertion part 36, which is configured to be inserted into the positioning hole when the moving part 41 moves toward the notch.

[0055] When the two sliding parts 443 separate and the two support rods 442 rotate in a direction perpendicular to the axial direction of the receiving channel 43, the moving part 41 moves upward as a whole and moves toward the notch, so that the insertion part 36 can be inserted into the positioning hole, so that the insertion part 36 and the positioning hole cooperate to axially position the moving part 41.

[0056] See Figure 6 In some embodiments, the drive component 42 has a hollow structure, and the moving part 41 is inserted into the drive component 42.

[0057] The movable part 41 is inserted into the driving member 42, so that the movable part 41 can move relative to the driving member 42.

[0058] See Figure 6 In some embodiments, guide portions 35 are provided on both sides of the collection cavity 3 in a direction perpendicular to the axial direction of the receiving channel 43, and the guide portions 35 are disposed opposite to the notch of the receiving channel 43.

[0059] The flow guide 35 can extend along the axial direction of the receiving channel 43.

[0060] When the two sliding parts 443 separate and the two support rods 442 rotate in a direction perpendicular to the axis of the receiving channel 43, the moving part 41 moves upward as a whole, and the support rods 442, carrying the flexible filter screen 441, abut against the bottom of the guide part 35. This can position the moving part 41 on the one hand, and reduce the risk of solids falling outside the flexible filter screen 441 by blocking the edge of the flexible filter screen 441 by the guide part 35.
