Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a plasma-based integrated treatment device for oily sludge. Background Technology

[0002] The oil extraction and refining industry generates approximately 30 million tons of oil sludge annually. Oil sludge is classified as hazardous solid waste (number HW08) in the Solid Waste Catalogue. Common methods for treating oil sludge include landfilling, chemical extraction, and microbial decomposition. Landfilling directly pollutes the soil, chemical extraction causes secondary pollution, and microbial decomposition has a long processing time that cannot meet the needs of treating large quantities of oil sludge. Therefore, none of these methods can fundamentally solve the problem.

[0003] Research has shown that using plasma torch technology, with supplemental heat (diesel, natural gas, crude oil, or biomass oil), can burn organic matter in oil sludge to reduce its volume and render it harmless. 95% of the combustion heat is converted into hot steam, which can then be used for heating or well injection, achieving multi-stage energy utilization. It can also be applied to waste heat recovery power generation to supply the power consumption of the equipment itself. The glassy tailings can be used as building aggregates and can be further used to produce micro glass beads, which can be used for sewage filtration, road reflective agents, rust removal abrasives, etc., achieving resource utilization.

[0004] Existing plasma-based integrated treatment devices for oily sludge have certain drawbacks during use. For example, after the plasma gasifier processes the incoming oily sludge and cools it to generate tailings, when the discharge port is opened, too much tailings are discharged at once, making subsequent transfer inconvenient. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art:

[0006] When discharging tailings in existing plasma gasifiers, excessive tailings are discharged at once after the sealing plate at the feed inlet is opened, making subsequent transfer inconvenient.

[0007] A plasma-based integrated treatment device for oily sludge was proposed.

[0008] To achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A plasma-based comprehensive treatment device for oily sludge includes a plasma gasifier. The lower end face of the plasma gasifier has a discharge port. A sealing plate for use with the discharge port is provided on the plasma gasifier. A discharge hood is fixed on the lower end face of the plasma gasifier and directly below the discharge port. A rotating shaft is rotatably installed inside the discharge hood. An installation sleeve is fixedly fitted on the outer wall of the rotating shaft. Multiple partition plates are fixed on the outer wall of the installation sleeve. A motor for driving the rotating shaft is fixed on the outer wall of the discharge hood.

[0010] As a further technical solution of the present invention, a mounting post is fixed on one side of each partition plate and at a position away from the mounting sleeve, and the end of each connecting post is conical.

[0011] As a further technical solution of the present invention, a connecting seat is fixed on one side of the feeding hood, a rotating column is rotatably provided through the upper end surface of the connecting seat, a rotating disk is fixed at the lower end of the rotating column, a plurality of collision units are provided on the rotating disk, and a linkage unit one is provided on the feeding hood to cooperate with the rotating column.

[0012] As a further technical solution of the present invention, each collision unit includes a collision plate rotatably disposed on a rotating disk. The rotating disk has multiple slots that cooperate with the corresponding collision plates. Connecting columns are fixed on the upper and lower end faces of the collision plate. Mounting circular grooves that cooperate with the connecting columns are provided in the slots. A torsion spring is fixed between the collision plate and the corresponding mounting circular groove. The torsion spring is movably sleeved on the outer side wall of the corresponding connecting column.

[0013] As a further technical solution of the present invention, the linkage unit includes a driven bevel gear fixed to the upper end of the rotating column, and the end of the rotating shaft away from the motor rotates through the unloading cover and is fixed with an active bevel gear, and the active bevel gear meshes with the driven bevel gear.

[0014] As a further technical solution of the present invention, a conveyor frame is provided below the material feeding hood, a conveyor belt is rotatably mounted on the conveyor frame, a rotating shaft is rotatably mounted inside the conveyor frame, a drive roller for use with the conveyor belt is fixedly sleeved on the outer side wall of the rotating shaft, and a motor for driving the rotating shaft is fixedly mounted on the side wall of the conveyor frame.

[0015] As a further technical solution of the present invention, two side baffles are symmetrically fixed on the upper end face of the conveyor frame.

[0016] As a further technical solution of the present invention, two mounting seats are symmetrically fixed on the lower end face of one end of the conveyor frame, and a rotating shaft three is rotatably arranged between the two mounting seats. A brush layer is fixed on the outer side wall of the rotating shaft three, and a linkage component two is provided on the conveyor frame to cooperate with the rotating shaft three.

[0017] As a further technical solution of the present invention, the end of the rotating shaft two away from the motor two rotates through the conveyor frame, the linkage component two includes a large gear disk fixedly sleeved on the outer wall of the rotating shaft two, one end of the rotating shaft three rotates through the mounting base and is fixedly sleeved with a small gear disk, and a chain is used for transmission between the large gear disk and the small gear disk.

[0018] As a further technical solution of the present invention, two plasma torches are fixedly and continuously disposed on the upper end face of the plasma gasification furnace, and a centrifugal slurry pump and a heat exchange boiler are respectively connected to both sides of the plasma gasification furnace, and a tail gas processor is connected to one side of the heat exchange boiler.

[0019] The beneficial effects of this invention are:

[0020] 1. When the oil sludge enters the plasma gasification furnace through the centrifugal slurry pump, the plasma gasification furnace processes the oil sludge under the action of the plasma torch. After cooling, tailings are generated. Then the sealing plate is opened, and the tailings fall into the feeding hood. At this time, the motor drives the rotating shaft, the mounting sleeve and each partition plate to rotate counterclockwise, thereby causing the tailings to fall in batches, which facilitates the subsequent transportation and transfer of the tailings.

[0021] 2. During the process of the rotating shaft driving the partition plate to discharge material, it drives the rotating disk and the collision plate to rotate together. When the partition plate rotates to a position away from the discharge hood, the corresponding collision plate hits the partition plate, causing the partition plate to vibrate, thereby preventing tailings and debris from getting stuck between the installation columns.

[0022] 3. When the second motor drives the second rotating shaft to rotate, it will drive the large gear disk to rotate, which in turn drives the small gear disk, the third rotating shaft, and the brush layer to rotate via the chain. The brush layer contacts the surface of the conveyor belt, and during the rotation, the brush layer can clean the tail residue and debris located in the texture of the conveyor belt.

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] Reference Figures 1-7 A plasma-based comprehensive treatment device for oily sludge includes a plasma gasifier 1. A centrifugal slurry pump and a heat exchange boiler are respectively connected to both sides of the plasma gasifier 1. A tail gas processor is connected to one side of the heat exchange boiler. Two plasma torches 28 are fixedly installed through the upper end face of the plasma gasifier 1. A feeding port is opened on the lower end face of the plasma gasifier 1. A sealing plate for use with the feeding port is movably installed on the plasma gasifier 1. A feeding hood 2 is fixedly installed on the lower end face of the plasma gasifier 1 and directly below the feeding port. A rotating shaft 3 is rotatably installed inside the feeding hood 2. An installation sleeve 4 is fixedly fitted on the outer wall of the rotating shaft 3. Multiple partition plates 5 are fixed on the outer wall of the installation sleeve 4. A motor 6 for driving the rotating shaft 3 is fixedly installed on the outer wall of the feeding hood 2.

[0033] Reference Figure 1 , Figure 2 and Figure 3 When the oil sludge enters the plasma gasification furnace 1 through the centrifugal slurry pump, the plasma gasification furnace 1 processes the oil sludge under the action of the plasma torch 28. After cooling, tailings are generated. Then the sealing plate is opened and the tailings fall into the feeding hood 2. At this time, the motor 6 drives the rotating shaft 3, the mounting sleeve 4 and each partition plate 5 to rotate counterclockwise, thereby causing the tailings to fall in batches, which facilitates the subsequent transportation and transfer of the tailings.

[0034] Reference Figure 2 and Figure 3Each partition plate 5 has a mounting post 7 fixed on one side away from the mounting sleeve 4, and the end of each connecting post 13 is conical.

[0035] As the partition plate 5 rotates, it drives each mounting column 7 to rotate together, performing the tailings removal operation.

[0036] Reference Figure 3 A connecting seat 8 is fixed on one side of the feeding cover 2. A rotating column 9 is rotatably installed through the upper end of the connecting seat 8. A rotating disk 10 is fixed at the lower end of the rotating column 9. Multiple collision units are provided on the rotating disk 10. A linkage unit 1 is provided on the feeding cover 2 to cooperate with the rotating column 9.

[0037] Reference Figure 3 and Figure 4 Each collision unit includes a collision plate 11 rotatably mounted on a rotating disk 10. The rotating disk 10 has multiple notches 12 that cooperate with the corresponding collision plate 11. The upper and lower end faces of the collision plate 11 are fixed with connecting posts 13. The notches 12 have mounting grooves that cooperate with the connecting posts 13. A torsion spring 14 is fixed between the collision plate 11 and the corresponding mounting groove. The torsion spring 14 is movably sleeved on the outer side wall of the corresponding connecting post 13.

[0038] Reference Figure 2 and Figure 3 During the process of rotating shaft 3 driving partition plate 5 to discharge material, rotating disk 10 and collision plate 11 rotate together. When partition plate 5 rotates to a position away from discharge hood 2, the corresponding collision plate 11 hits partition plate 5, causing partition plate 5 to vibrate, thereby preventing tailings and debris from getting stuck between mounting columns 7.

[0039] Reference Figure 2 and Figure 3 When the collision plate 11 hits the partition plate 5, the mounting sleeve 4 continues to drive the partition plate 5 to rotate, and the rotating disk 10 also continues to drive the collision plate 11 to rotate. At this time, the end of the collision plate 11 rotates towards the mounting sleeve 4 under the resistance of the partition plate 5 to avoid affecting the movement of the partition plate 5. During this process, the torsion spring 14 generates elastic deformation and stores elastic potential energy. When the partition plate 5 passes the corresponding collision plate 11, the end of the collision plate 11 rotates away from the mounting sleeve 4 under the action of the elastic potential energy of the torsion spring 14, so that it can be used again.

[0040] Reference Figure 3 The linkage unit includes a driven bevel gear 15 fixed to the upper end of the rotating column 9. The end of the rotating shaft 3 away from the motor 6 rotates through the unloading cover 2 and is fixed with a driving bevel gear 16. The driving bevel gear 16 meshes with the driven bevel gear 15.

[0041] Reference Figure 3During the process of driving the rotating shaft 3 to rotate, the motor 6 will drive the active bevel gear 16 to rotate, thereby driving the rotating column 9, rotating disk 10 and collision plate 11 to rotate through the driven bevel gear 15.

[0042] Reference Figure 1 and Figure 6 Below the material discharge cover 2, there is a conveyor frame 17. A conveyor belt 18 is rotatably mounted on the conveyor frame 17. The surface of the conveyor belt 18 is textured to increase the friction between it and the object to be conveyed. A rotating shaft 19 is rotatably mounted inside the conveyor frame 17. A drive roller for use with the conveyor belt 18 is fixedly mounted on the outer wall of the rotating shaft 19. A motor 20 for driving the rotating shaft 19 is fixed on the side wall of the conveyor frame 17.

[0043] Motor 20 drives rotating shaft 2 19 and drive roller to rotate, thereby driving conveyor belt 18 to rotate. In use, collection box can be placed at one end of conveyor frame 17 to receive the conveyed tailings.

[0044] Reference Figure 1 and Figure 6 Two side baffles 21 are symmetrically fixed on the upper end of the conveyor frame 17. The side baffles 21 prevent the tailings from falling from the discharge hood 2 onto the conveyor belt 18 and bouncing outwards from the conveyor frame 17, thus affecting the conveying and transfer of the tailings.

[0045] Reference Figure 6 and Figure 7 Two mounting seats 22 are symmetrically fixed on the lower end face of one end of the conveyor frame 17. A rotating shaft 23 is rotatably arranged between the two mounting seats 22. A brush layer 24 is fixed on the outer wall of the rotating shaft 23. A linkage component 2 is provided on the conveyor frame 17 to cooperate with the rotating shaft 23.

[0046] Reference Figure 6 and Figure 7 The end of the rotating shaft 219 away from the motor 20 rotates through the conveyor frame 17. The linkage component 2 includes a large gear disk 25 fixedly sleeved on the outer wall of the rotating shaft 219. One end of the rotating shaft 323 rotates through the mounting base 22 and is fixedly sleeved with a small gear disk 26. A chain 27 is connected between the large gear disk 25 and the small gear disk 26.

[0047] Reference Figure 6 and Figure 7 When the second motor 20 drives the second rotating shaft 19 to rotate, it will drive the large gear disk 25 to rotate, and drive the small gear disk 26, the third rotating shaft 23 and the brush layer 24 to rotate through the chain 27. The brush layer 24 contacts the surface of the conveyor belt 18. During the rotation, the brush layer 24 can clean the tail residue and debris located in the texture of the conveyor belt 18.

[0048] When using this invention, refer to Figure 1 , Figure 2 and Figure 3 When the oil sludge enters the plasma gasification furnace 1 through the centrifugal slurry pump, the plasma gasification furnace 1 processes the oil sludge under the action of the plasma torch 28. After cooling, tailings are generated. Then the sealing plate is opened and the tailings fall into the feeding hood 2. At this time, the motor 6 drives the rotating shaft 3, the mounting sleeve 4 and each partition plate 5 to rotate counterclockwise, thereby causing the tailings to fall in batches, which facilitates the subsequent transportation and transfer of the tailings.

[0049] Reference Figure 2 and Figure 3 During the process of rotating shaft 3 driving partition plate 5 to discharge material, rotating disk 10 and collision plate 11 rotate together. When partition plate 5 rotates to a position away from discharge hood 2, the corresponding collision plate 11 hits partition plate 5, causing partition plate 5 to vibrate, thereby preventing tailings and debris from getting stuck between mounting columns 7.

[0050] Reference Figure 2 and Figure 3 When the collision plate 11 hits the partition plate 5, the mounting sleeve 4 continues to drive the partition plate 5 to rotate, and the rotating disk 10 also continues to drive the collision plate 11 to rotate. At this time, the end of the collision plate 11 rotates towards the mounting sleeve 4 under the resistance of the partition plate 5 to avoid affecting the movement of the partition plate 5. During this process, the torsion spring 14 generates elastic deformation and stores elastic potential energy. When the partition plate 5 passes the corresponding collision plate 11, the end of the collision plate 11 rotates away from the mounting sleeve 4 under the action of the elastic potential energy of the torsion spring 14, so that it can be used again.

[0051] Reference Figure 1 and Figure 6 Motor 20 drives rotating shaft 19 and drive roller to rotate, thereby driving conveyor belt 18 to rotate. In use, collection box can be placed at one end of conveyor frame 17 to receive the conveyed tailings. When motor 20 drives rotating shaft 19 to rotate, it will drive large gear disk 25 to rotate, which will drive small gear disk 26, rotating shaft 23 and brush layer 24 to rotate through chain 27. Brush layer 24 contacts the surface of conveyor belt 18. During the rotation, brush layer 24 can clean the tailings and debris located in the texture of conveyor belt 18. No manual cleaning is required, making it convenient to use.
