Technical Field
[0001] This application relates to the field of petroleum heating technology, and in particular to an energy-saving heating device for oilfield gathering and transportation pipelines. Background Technology
[0002] Petroleum exists in various forms, including crude oil, natural gas, liquefied natural gas, and natural tar. Petroleum refers to a mixture of liquid and solid hydrocarbons, a viscous, dark brown liquid found naturally. While the term "petroleum" is often used to define "crude oil," it is commonly referred to as the "blood of industry." Petroleum is stored in parts of the Earth's upper crust and is primarily a mixture of various alkanes, cycloalkanes, and aromatics. It is a major target for geological exploration. After extraction, the extracted petroleum needs to be transported. Due to its high viscosity and poor fluidity, petroleum requires heating during transport to increase its fluidity and facilitate transport. Traditional heating methods primarily involve gas heating or burning crude oil. However, burning crude oil easily generates pollution and consumes some crude oil, reducing production. Currently, some petroleum transportation heating methods have switched to electric heating, which offers advantages such as rapid heating and wide applicability.
[0003] Existing electric heating methods for oil transportation mainly involve fixing an electric heating sleeve to the outside of the oil pipeline and then heating the pipeline. However, since heat is transferred from the outside to the inside during the heating process, the oil inside the pipeline flows at a faster speed on the outside and a slower speed in the middle. This results in uneven heating of the oil, leading to a difference in oil flow velocity. The slower-flowing oil obstructs the faster-flowing oil, thereby reducing the efficiency of oil transportation and increasing the energy consumption of oil transportation. To address this, an energy-saving heating device for oilfield gathering and transportation pipelines is proposed. Summary of the Invention
[0004] This application proposes an energy-saving heating device for oilfield gathering and transportation pipelines, which can uniformly heat oil, avoid oil flow rate differences, increase oil discharge efficiency, promote oil heating, and improve oil heating efficiency, thereby achieving the advantages of energy saving and solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this application adopts the following technical solution: an energy-saving heating device for oilfield gathering and transportation pipelines, comprising a support frame, characterized in that: an oil pipeline for transporting oil is fixedly installed at the top of the support frame; an oil inlet is provided at the left end of the oil pipeline; an oil outlet is provided at the right end of the oil pipeline; a connecting flange one for connecting the oil inlet pipeline is fixedly installed at the oil inlet of the oil pipeline; a connecting flange two for connecting the oil outlet pipeline is fixedly installed at the oil outlet of the oil pipeline; an electric heating sleeve for heating oil is fixedly connected to the outer surface of the oil pipeline; a diversion device is provided inside the oil pipeline; a rotating device is provided inside the oil pipeline; and an electromagnetic reaction device is provided inside the oil pipeline.
[0006] Furthermore, the diversion device includes a spiral guide bar, which is fixedly connected to the inner wall of the oil pipeline. The spiral guide bar is configured as an auger, and a channel for oil flow is opened in the middle of the spiral guide bar.
[0007] Furthermore, the rotating device includes a fixed rod, which is fixedly connected to the inner wall of the oil pipeline. A fixed sleeve for support is fixedly connected to the middle of the fixed rod, and a rotating shaft for rotation is rotatably sleeved in the middle of the fixed sleeve.
[0008] Furthermore, a fixed block for support is fixedly sleeved on the outer surface of the rotating shaft near the oil inlet, and a vortex blade for bearing force is fixedly connected to the outer surface of the fixed block.
[0009] Furthermore, the outer surface of the rotating shaft is provided with a reciprocating thread, and a reciprocating magnetic slider for movement is sleeved on the outer surface of the rotating shaft at the reciprocating thread, and a deflection device is provided on the reciprocating magnetic slider.
[0010] Furthermore, the electromagnetic device includes an electromagnetic coil, which is fixedly installed inside the side wall of the oil pipeline, and the reciprocating magnetic slider is within the magnetic field range of the electromagnetic coil.
[0011] This application provides an energy-saving heating device for oilfield gathering and transportation pipelines. By designing a spiral guide bar, when oil enters the pipeline, the continuous inflow of oil causes the oil that enters first to be pushed by the oil that enters later. At this time, the spiral guide bar guides the oil to move in a spiral shape. In conjunction with the use of an electric heating sleeve, the oil in the middle of the pipeline can also be guided to a position close to the electric heating sleeve, so that the oil inside the pipeline can be fully heated and uneven heating of the oil is avoided.
[0012] Simultaneously, the thrust of the oil causes the eddy current blades to rotate during its movement. The eddy current blades, through the fixed sleeve, drive the rotating shaft to rotate, causing the reciprocating magnetic slider to reciprocate along the reciprocating thread. Since the reciprocating magnetic slider is within the magnetic field range of the electromagnetic coil, an electromagnetic effect is generated between the reciprocating magnetic slider and the electromagnetic coil, causing a current to be generated inside the electromagnetic coil. This current cannot be consumed and can only be dissipated as heat. The heat generated by the electromagnetic coil is then used to heat the oil, which promotes the transportation of oil and saves energy.
[0013] Secondly, when the reciprocating magnetic slider moves towards the oil outlet, the deflection plate is deflected along the hinge to a position perpendicular to the axis of the reciprocating magnetic slider due to the obstruction of the oil. Then, the deflection plate is limited by the limiting block. At this time, the deflection plate, after unfolding, will exert a thrust on the oil, thereby accelerating the transport of the oil and allowing the oil to flow out of the oil pipeline quickly. When the reciprocating magnetic slider moves towards the oil inlet, the deflection plate is retracted by the hinge, thereby cutting and stirring the flowing oil, making the oil heated more evenly and improving the heating efficiency of the oil.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0018] Please see Figures 1-4 An energy-saving heating device for oilfield gathering and transportation pipelines includes a support frame 1. An oil pipeline 2 for transporting oil is fixedly installed at the top of the support frame 1. An oil inlet 3 is located at the left end of the oil pipeline 2, and an oil outlet 4 is located at the right end. A connecting flange 5 is fixedly installed at the oil inlet 3 to connect to the inlet pipeline, facilitating the entry of oil into the oil pipeline 2 for transportation. A connecting flange 6 is fixedly installed at the oil outlet 4 to connect to the outlet pipeline, facilitating the discharge of heated oil through the outlet 4. An electric heating sleeve 7 is fixedly connected to the outer surface of the oil pipeline 2 for heating oil. After the oil enters the oil pipeline 2, the electric heating sleeve 7 heats the oil inside the oil pipeline 2, thereby increasing the fluidity of the oil and facilitating its transportation. A diversion device, a rotating device, and an electromagnetic reaction device are installed inside the oil pipeline 2.
[0019] Please see Figures 1-4 The flow guiding device includes a spiral guide bar 8, which is fixedly connected to the inner wall of the oil pipeline 2. The spiral guide bar 8 is configured as an auger, and a channel for oil flow is opened in the middle of the spiral guide bar 8. The oil is guided through the auger-shaped spiral guide bar 8, so that the oil in the middle of the oil pipeline 2 can be guided to the vicinity of the electric heating sleeve 7, preventing the oil in the middle of the oil pipeline 2 from heating slowly and causing a flow rate difference.
[0020] Please see Figures 1-4 The rotating device includes a fixed rod 9, which is fixedly connected to the inner wall of the oil pipeline 2. A fixed sleeve 10 for support is fixedly connected to the middle of the fixed rod 9. A rotating shaft 11 for rotation is rotatably sleeved in the middle of the fixed sleeve 10, ensuring that the rotating shaft 11 can rotate relative to the fixed sleeve 10. The stability of the rotating shaft 11 during rotation can be guaranteed by the fixed sleeve 10.
[0021] Please see Figures 1-4A fixed block 12 for support is fixedly sleeved on the outer surface of the rotating shaft 11 near the oil inlet 3. A vortex blade 13 for bearing force is fixedly connected to the outer surface of the fixed block 12, so that the vortex blade 13 rotates under the action of oil flow, and then the vortex blade 13 drives the rotating shaft 11 to rotate synchronously through the fixed block 12.
[0022] Please see Figures 1-4 The outer surface of the rotating shaft 11 is provided with a reciprocating thread 14. A reciprocating magnetic slider 15 for movement is connected to the outer surface of the rotating shaft 11 at the reciprocating thread 14. A deflection device is provided on the reciprocating magnetic slider 15 to ensure that when the rotating shaft 11 rotates, the reciprocating magnetic slider 15 can be driven to reciprocate through the reciprocating thread 14.
[0023] Please see Figures 1-4 The electromagnetic device includes an electromagnetic coil 16, which is fixedly installed inside the side wall of the oil pipeline 2. The reciprocating magnetic slider 15 is located within the magnetic field range of the electromagnetic coil 16. When the reciprocating magnetic slider 15 moves back and forth within the magnetic field range of the electromagnetic coil 16, an electromagnetic effect is generated between the reciprocating magnetic slider 15 and the electromagnetic coil 16. The electromagnetic effect is then used to induce a current in the electromagnetic coil 16, and the heat generated by the electromagnetic coil 16 is used to promote the heating of the oil.
[0024] Please see Figures 1-4 The deflection device includes a hinge 17, which is fixedly connected to the outer surface of the reciprocating magnetic slider 15. The reciprocating magnetic slider 15 is rotatably connected to a deflection plate 18 via the hinge 17. A limiting block 19 for limiting is fixedly connected to the outer surface of the reciprocating magnetic slider 15, ensuring that the deflection plate 18 can be deflected along the outer surface of the reciprocating magnetic slider 15 via the hinge 17, so that the deflection plate 18 can extend and retract.
[0025] Please see Figures 1-4 The rotating shaft 11 is located in the channel in the middle of the spiral guide bar 8, and the limiting block 19 is located at the position where the deflection plate 18 is perpendicular to the axis of the reciprocating magnetic slider 15, so that the deflection plate 18 can apply force to the oil after it extends.
[0026] Please see Figures 1-4 The deflection plate 18 is deflected relative to the reciprocating magnetic slider 15 via the hinge 17. The area formed by the fully extended deflection plate 18 is smaller than the cross-sectional area of the central channel of the spiral guide bar 8. When the reciprocating magnetic slider 15 moves toward the oil outlet 4, the extended deflection plate 18 pushes out the oil. When the reciprocating magnetic slider 15 moves toward the oil inlet 3, the contracted deflection plate 18 agitates the oil, ensuring the uniformity of oil heating.
[0027] Working principle: When the equipment is in use, the oil inlet 3 of the oil pipeline 2 is connected to the oil inlet pipe via connecting flange 1 5, and the oil outlet 4 of the oil pipeline 2 is connected to the oil outlet pipe via connecting flange 2 6. Then, oil is introduced into the interior of the oil pipeline 2, and the electric heating sleeve 7 is turned on to heat the oil inside the oil pipeline 2. Simultaneously, as the oil enters the oil pipeline 2, the continuous inflow of oil causes the oil that enters first to be pushed by the oil that enters later. At this time, the spiral guide... The guide bar 8 directs the oil in a spiral motion, which, in conjunction with the use of the electric heating sleeve 7, guides the oil in the middle of the oil pipeline 2 to a position close to the electric heating sleeve 7. This ensures that the oil inside the oil pipeline 2 is fully heated, preventing uneven heating. Simultaneously, the thrust of the oil causes it to move, pushing the vortex blades 13 to rotate. The vortex blades 13, through the fixed block 12, drive the rotating shaft 11 to rotate, causing the reciprocating magnetic slider 15 to move along the reciprocating path. The thread 14 reciprocates. Since the reciprocating magnetic slider 15 is within the magnetic field range of the electromagnetic coil 16, an electromagnetic effect is generated between the reciprocating magnetic slider 15 and the electromagnetic coil 16, causing a current to be generated inside the electromagnetic coil 16. This current cannot be dissipated but is instead released as heat. This heat is used to heat the oil, thus facilitating its transport. Furthermore, as the reciprocating magnetic slider 15 moves towards the oil outlet 4... Due to the obstruction of the oil, the deflector plate 18 deflects along the hinge 17 to a position perpendicular to the axis of the reciprocating magnetic slider 15. Then, the deflector plate 18 is limited by the limiting block 19. At this time, the deflector plate 18, after being unfolded, will exert a pushing force on the oil, thereby accelerating the transportation of the oil and allowing the oil to flow out of the oil pipeline 2 quickly. When the reciprocating magnetic slider 15 moves towards the oil inlet 3, the deflector plate 18 is retracted by the hinge 17, thereby cutting and stirring the flowing oil, making the oil heated more evenly and improving the heating efficiency of the oil.
