Description

Technical Field

[0001] This invention relates to the field of oil-based rock cuttings resource utilization technology, specifically to an oil-based rock cuttings dry slag treatment system. Background Technology

[0002] Oil-based cuttings are oil-containing solid waste generated during oil and gas drilling. Their main components include drill cuttings, drilling fluid additives, formation cuttings, and crude oil. After preliminary processing, oil-based cuttings can be processed into dry oil-based cuttings. However, this dry oil-based cuttings can only be reused in small quantities as road paving material, resulting in a relatively low resource utilization rate.

[0003] In the prior art, such as the patent document with application number 202311268437.9, a shale gas drilling oil mud dry residue treatment device and system is disclosed. The rotary kiln is used to further process the oil-based rock cuttings dry residue, and the oil, organic matter and water are removed by full pyrolysis. As a result, the oil-based rock cuttings dry residue can meet the fly ash standard after deep processing, thereby improving its application range and improving resource utilization.

[0004] In practice, it has been found that oil-based rock cuttings undergo drying, pyrolysis, and carbonization stages sequentially in a rotary kiln. Particularly during the pyrolysis and carbonization stages, significant coking occurs. One reason for this is that some oil-based rock cuttings clump together in the rotary kiln, leading to uneven heat transfer of asphaltenes and resins, causing condensation reactions and coke formation, thus affecting the processing quality of the oil-based rock cuttings. Therefore, reducing the probability of coking and improving processing quality is an urgent problem to be solved. Summary of the Invention

[0024] See Figures 1 to 8 This embodiment provides an oil-based rock cuttings dry slag treatment system, including a frame 10, a first cylinder 20, a second cylinder 30, a drive mechanism 40, an installation cylinder 50, a first motor 52, a first rotating shaft 53, and a crushing rod 54.

[0025] This oil-based rock cuttings dry slag treatment system is used to further process oil-based rock cuttings dry slag (hereinafter referred to as dry slag), and is an improvement on the existing rotary kiln technology.

[0026] The first cylinder 20 is rotatably mounted on the frame 10, and is inclined. Multiple circumferentially distributed strip-shaped protrusions 21 extending axially are provided on the inner wall of the first cylinder 20. The second cylinder 30 is rotatably mounted on the frame 10, and is coaxial with the first cylinder 20. Multiple circumferentially distributed strip-shaped protrusions 21 extending axially are provided on the inner wall of the second cylinder 30. Specifically, the structures of the first cylinder 20 and the second cylinder 30 can refer to the structures of rotary kiln bodies in the prior art. The drive mechanism 40 is used to drive the first cylinder 20 and the second cylinder 30 to rotate. The drive mechanism 40 can refer to the support devices (including rollers, support rollers, and thrust rollers, etc.) of rotary kilns in the prior art. The cross-sectional shape of the strip-shaped protrusions 21 can be an isosceles trapezoid or other shapes. The overall length of the first cylinder 20 and the second cylinder 30 can be set from tens of meters to hundreds of meters as needed.

[0027] The difference lies in that this system divides the rotary kiln's cylinder into two parts (first cylinder 20 and second cylinder 30), and introduces an installation cylinder 50. The installation cylinder 50 is fixedly mounted on the frame 10, with its two ends dynamically sealed to the ends of the first cylinder 20 and second cylinder 30 respectively. The installation cylinder 50 is coaxial with the first cylinder 20, and a first hole 51 is formed on its upper side. A first motor 52 is connected to the outer wall of the installation cylinder 50. One end of a first rotating shaft 53 is connected to the output end of the motor, and the other end of the first rotating shaft 53 passes through the first hole 51 and is located inside the installation cylinder 50, with the first rotating shaft 53 being vertical. One end of a crushing rod 54 is connected to the end of the first rotating shaft 53 away from the first motor 52, and the other end of the crushing rod 54 rotates horizontally with the first rotating shaft 53. Referring to existing rotary kilns, the first cylinder 20 serves as the drying section, and the second cylinder 30 includes a pyrolysis section and a carbonization section. Specifically, the mounting cylinder 50 is relatively narrow, so some dry slag accumulates on the lower inner wall of the mounting cylinder 50. After accumulating to a certain height, the dry slag will slide down into the second cylinder 30 under gravity. Alternatively, the second cylinder 30 can be divided into two parts, with the mounting cylinder 50, the first rotating shaft 53, and the crushing rod 54 added in between to further disperse the dry slag. The first hole 51 and the first rotating shaft 53 are dynamically sealed.

[0028] In this embodiment, as the first cylinder 20 and the second cylinder 30 rotate, the dry slag is conveyed from the first cylinder 20 to the second cylinder 30 and passes through the mounting cylinder 50. During this process, the dry slag is located between the strip-shaped protrusions 21 on the inner walls of the first cylinder 20 and the second cylinder 30. As the first cylinder 20 and the second cylinder 30 rotate, the dry slag is lifted and slides down along the side of the strip-shaped protrusions 21, making a parabolic motion as it falls to the bottom of the first cylinder 20 or the second cylinder 30. When the dry slag is located at the end of the first cylinder 20 near the second cylinder 30 and rotates with the first cylinder 20, the dry slag passes through the rotating crushing rod 54 after falling, thereby breaking up any clumps of dry slag. This results in a more uniform dispersion of the dry slag after falling, making the subsequent heating of the dry slag more uniform, reducing coking, and improving the processing quality of the dry slag.

[0029] Furthermore, by placing the first motor 52 outside the mounting cylinder 50 and the first shaft 53 extending into the mounting cylinder 50 through the first hole 51, the length of the first shaft 53 can be shortened, thereby reducing costs. Moreover, the shorter length of the first shaft 53 reduces the power requirements of the first motor 52, extending its lifespan. During the high-speed rotation of the crushing rod 54 driven by the motor, the ordinary first shaft 53 can maintain rigidity, achieving a good dry slag dispersal effect. This design is reasonable, reliable, and compact.

[0030] In one embodiment, the oil-based rock cuttings dry slag treatment system further includes a guide block 55. The guide block 55 is connected to the lower inner wall of the mounting cylinder 50; the upper end of the guide block 55 is provided with an inclined guide surface 56. There are gaps between the two sides of the guide block 55 and the ends of the corresponding strip-shaped protrusions 21. The guide surface 56 is inclined towards the second cylinder 30.

[0031] In this embodiment, the dry residue conveyed by the first cylinder 20 slides down the guide surface 56 into the second cylinder 30 when it falls onto the guide block 55 at the bottom of the mounting cylinder 50.

[0032] In one embodiment, multiple crushing rods 54 are provided; the multiple crushing rods 54 are distributed at axial intervals along the first rotating shaft 53. The multiple crushing rods 54 may be evenly distributed.

[0033] In this embodiment, when the dry residue is located between two adjacent strip-shaped protrusions 21 and at one end of the first cylinder 20 near the second cylinder 30, the crushing rod 54 inside the mounting cylinder 50 rotates to form a circular crushing area, such as... Figure 7 As the first cylinder 20 rotates counterclockwise, the dry slag located on the lower side of the first cylinder 20 gradually rises along the strip-shaped protrusion 21 and moves to the right inner wall of the first cylinder 20. At this time, the dry slag gradually slides down along the upper surface of the strip-shaped protrusion 21. Since the first cylinder 20 is tilted, this causes the dry slag to slide from the strip-shaped protrusion into the mounting cylinder 50 and fall onto the crushing area, where it is dispersed by the crushing rod 54. At the same time, the first cylinder 20 continues to rotate, and the dry slag falls into the crushing area, covering a region. The large difference in linear velocity between the two ends of the crushing rod 54 results in a large difference in the impact force on the dry slag at different positions of the crushing rod 54. The end of the crushing rod 54 furthest from the first rotating shaft 53 has the best dispersing effect on the dry slag, corresponding to the outer periphery of the crushing area. However, when the dry slag falls, it is distributed from the outer periphery of the crushing area towards the crushing area, which makes the dispersing effect of the dry slag near the first rotating shaft 53 not very good. By setting multiple crushing rods 54, which are distributed from top to bottom on the first rotating shaft 53, the clumps of dry slag sliding down the inner wall of the rotating first cylinder 20 can be broken up by the outermost ends of the multiple crushing rods 54. Figure 7 The direction of the arrow indicates the movement trajectory of the dry residue, thus allowing the dry residue to be dispersed as evenly as possible.

[0034] In one embodiment, the lower end of the first rotating shaft 53 is provided with a second hole 531 along the axial direction, and the side wall of the first rotating shaft 53 is provided with a strip window 532 along the axial direction.

[0035] The oil-based rock cuttings dry slag treatment system also includes a linkage component 60, a first spring 70, a limit ring 71, and a power component 80.

[0036] Multiple linkage components 60 are provided. One end of each linkage component 60 passes through the strip window 532 and slides within the second hole 531. The other end of each linkage component 60 is connected to the corresponding breaking rod 54. Multiple first springs 70 are provided, each located between two adjacent linkage components 60, with both ends of each first spring 70 abutting against the corresponding linkage component 60. A limiting ring 71 is located within the second hole 531, below all linkage components 60. The outer wall of the limiting ring 71 is connected to the inner wall of the second hole 531, and the upper end of the limiting ring 71 abuts against the corresponding linkage component 60. A power component 80 is used to drive the upper linkage components 60 to move vertically.

[0037] In this embodiment, the rotation speed of the first drum 20 is adjusted according to actual production needs. This causes a change in the distribution area of ​​the dry slag as it falls from the first drum 20 after being transported to a higher position. For example, when the rotation speed of the first drum 20 decreases, a large amount of dry slag falls towards the end of the lowest crushing rod 54, resulting in a large amount of dry slag that the crushing rod 54 needs to break up simultaneously, leading to poor breaking effect. At this time, the uppermost linkage component 60 is driven downward by the power component 80, causing multiple linkage components 60 to move downward along with the crushing rod 54. Under the action of the first spring 70, the multiple linkage components 60 can maintain approximately equal spacing as they move downward, allowing the crushing rod 54 to move downward at equal intervals. After all the crushing rods 54 move downward, they simultaneously break up the dry slag, achieving a better breaking effect. When the rotation speed of the first drum 20 increases, the crushing rods 54 can be adjusted to move further apart to adapt.

[0038] In one embodiment, a third hole 541 is provided at one end of the breaking rod 54 along its centerline.

[0039] The linkage assembly 60 includes a first sleeve 61, a first connecting rod 62, a second sleeve 63, a second connecting rod 64, a third sleeve 65, a third connecting rod 66, a second spring 67, a fourth connecting rod 68, and a fifth connecting rod 69.

[0040] The first sleeve 61 is coaxially slidably disposed within the second hole 531. One end of the first connecting rod 62 passes through the strip window 532 and connects to the outer wall of the first sleeve 61. The second sleeve 63 is coaxially slidably disposed within the second hole 531, and is located below the first sleeve 61. One end of the second connecting rod 64 passes through the strip window 532 and connects to the outer wall of the second sleeve 63. The third sleeve 65 is coaxially slidably disposed within the second hole 531, and is located between the first sleeve 61 and the second sleeve 63. One end of the third connecting rod 66 passes through the strip window 532 and connects to the third sleeve 65, and the other end of the third connecting rod 66 is slidably engaged with the third hole 541. The upper and lower ends of the second spring 67 pass through the third sleeve 65 respectively and abut against the first sleeve 61 and the second sleeve 63. One end of the fourth connecting rod 68 is hinged to the end of the first connecting rod 62 away from the first sleeve 61, and the other end of the fourth connecting rod 68 extends outward and is hinged to the outer wall of the breaking rod 54. One end of the fifth connecting rod 69 is hinged to the end of the second connecting rod 64 away from the second sleeve 63, and the other end of the fifth connecting rod 69 extends outward and is hinged to the outer wall of the breaking rod 54. The power assembly 80 is used to drive the first sleeve 61 in the upper linkage assembly 60 to move vertically, and the second sleeve 63 in the lower linkage assembly 60 abuts against the limiting ring 71.

[0041] In this embodiment, the power component 80 drives the first sleeve 61 in the uppermost linkage component 60 to move downward, which can compress the first spring 70 and the second spring 67, so that both the first sleeve 61 and the second sleeve 63 move downward.

[0042] As the distance between the first sleeve 61 and the second sleeve 63 is shortened, the fourth connecting rod 68 and the fifth connecting rod 69 cause the crushing rod 54 to slide on the third connecting rod 66 and move away from the first rotating shaft 53. This allows the end of the crushing rod 54 to get closer to the inner wall of the mounting cylinder 50. Even when the rotary kiln speed is very low, the end of the crushing rod 54 can still contact the dry slag sliding off the inner wall of the first cylinder 20, thus breaking up the dry slag.

[0043] In one embodiment, the guide block 55 has a fourth hole 551 in the vertical direction.

[0044] The power assembly 80 includes a first connecting sleeve 81, a second rotating shaft 82, and a second motor 83.

[0045] The upper end of the first connecting sleeve 81 is connected to the lower end of the limiting ring 71, and the lower end of the first connecting sleeve 81 passes through the fourth hole 551 and is located outside the mounting sleeve 50. The upper end of the rotating shaft passes sequentially through the first connecting sleeve 81, the limiting ring 71, multiple first sleeves 61, multiple second sleeves 63, and multiple third sleeves 65. The second rotating shaft 82 is threadedly connected to the inner wall of the first sleeve 61 in the linkage mechanism above. The second motor 83 is connected to the lower end of the first connecting sleeve 81, and the output end of the second motor 83 is connected to the lower end of the second rotating shaft 82.

[0046] In this embodiment, the second motor 83 drives the second rotating shaft 82 to rotate, causing the uppermost first sleeve 61 to slide vertically, thereby changing the vertical position and lateral extension position of the multiple breaking rods 54.

[0047] In one embodiment, the oil-based rock cuttings dry slag treatment system further includes a second connecting sleeve 90. The lower end of the second connecting sleeve 90 is connected to the upper end of the guide block 55; the upper end of the second connecting sleeve 90 is dynamically sealed to the inner wall of the third hole 541. The upper end of the second connecting sleeve 90 is rotatably connected to the inner wall of the third hole 541.

[0048] In this embodiment, the second connecting sleeve 90 can limit the lower end of the first rotating shaft 53, so that the lower end of the rotating first rotating shaft 53 remains rigid.

[0049] The oil-based rock cuttings dry slag treatment system also includes a baffle 91 located inside the second cylinder 30 and connected to the mounting cylinder 50. A gap exists between the outer periphery of the baffle 91 and the inner wall of the second cylinder 30. The baffle 91 can be circular and coaxial with the second cylinder 30. When the crushing rod 54 breaks up the clumps of dry slag, it easily sends the slag to a distant location, resulting in insufficient residence time of the slag within the second cylinder 30. By setting up a baffle 91 to block the dry slag ejected by the crushing rod 54, the dry slag can remain in the second cylinder 30 for a sufficient period of time.
