Description

Technical Field

[0001] This application relates to the field of petroleum heating technology, and in particular to an energy-saving zero-carbon heating device for oilfield transportation systems. Background Technology

[0002] Petroleum refers to a mixture of liquid and solid hydrocarbons, occurring naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but conventionally, "petroleum" is used to define "crude oil." Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." It is found in some areas of the Earth's upper crust and is primarily a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. 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 transportation. Traditional heating methods primarily use gas heating or... Combustion of crude oil is a common practice, but it easily generates pollution and consumes some of the crude oil, reducing production. Some existing heating methods have been replaced by electromagnetic heating, which can heat oil quickly and efficiently. However, because oil pipelines are relatively thick, and the electromagnetic heater is wrapped around the outer surface of the pipeline, the oil in the middle of the pipeline heats up slowly. This results in uneven heating of the oil inside the pipeline, causing a difference in oil flow velocity. The slower-flowing oil tends to accumulate, blocking the faster-flowing oil and thus affecting the oil transportation efficiency. Therefore, an energy-saving, zero-carbon heating device for oilfield transportation systems is proposed. Summary of the Invention

[0003] This application proposes an energy-saving zero-carbon heating device for oilfield transportation systems, which has the advantages of uniformly heating oil, avoiding flow velocity differences within the oil, and preventing oil blockage, thereby solving the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this application adopts the following technical solution: an energy-saving zero-carbon heating device for an oilfield transportation system, comprising a support frame and a heating cylinder. The heating cylinder is fixedly installed at the top of the support frame. An oil inlet is provided at the left end of the heating cylinder. An oil inlet connecting flange is fixedly installed at the oil inlet of the heating cylinder. An oil inlet pipe is fixedly connected to the heating cylinder through the oil inlet connecting flange. A control valve for controlling the flow of oil is provided on the oil inlet pipe. An oil outlet is provided at the right end of the heating cylinder. An oil outlet connecting flange is fixedly installed at the oil outlet of the heating cylinder. An oil outlet pipe is fixedly connected to the heating cylinder through the oil outlet connecting flange. Two symmetrically arranged electromagnetic heaters are fixedly installed on the outer surface of the heating cylinder. A spiral device is provided inside the heating cylinder. A water bath heating device is provided inside the heating cylinder.

[0005] Furthermore, the spiral device includes a fixed plate for support, the fixed plate being fixedly connected to the inner cavity side wall of the heating cylinder, and a rotating shaft for support being provided in the middle of the fixed plate.

[0006] Furthermore, a spiral auger for guiding oil flow is fixedly connected to the end of the rotating shaft away from the fixed plate.

[0007] Furthermore, the water bath heating device includes an isolation sleeve, which is fixedly connected to the inner wall of the heating cylinder, and the isolation sleeve and the inner wall of the heating cylinder together form a filling cavity for holding water.

[0008] Furthermore, the heating cylinder has a through groove inside its side wall to facilitate water flow, and a water inlet that is easy to open and close is fixedly installed on the outer surface of the heating cylinder at the through groove. A sealing cap is connected to the water inlet by a thread.

[0009] Furthermore, a rotating device is provided inside the heating cylinder, and the rotating device includes a ball bearing, which is disposed inside the fixed plate.

[0010] This application provides an energy-saving, zero-carbon heating device for an oilfield transportation system. By designing an electromagnetic heater, a fixed plate, a rotating shaft, and a spiral auger, when oil enters the heating cylinder, the spiral auger causes the oil to move along its spiral direction, bringing it close to the side wall of the heating cylinder. The spiral design of the auger guides the oil in the middle of the heating cylinder towards the side wall, ensuring uniform heating without flow rate differences and improving heating efficiency.

[0011] Meanwhile, by designing isolation sleeves, filling cavities, and through slots, the electromagnetic heater can heat the water inside the filling cavity while heating the oil. The heated water inside the filling cavity can then keep the oil inside the heating cylinder warm, ensuring that the oil always maintains high fluidity.

[0012] Secondly, by designing ball bearings, augers, and electromagnetic coils, the electromagnetic effect generated between the electromagnetic coils and the magnetic field inside the electromagnetic heater creates a motor-like relationship between the electromagnetic heater and the electromagnetic coils. In this case, the electromagnetic heater acts as the stator, while the electromagnetic coils and rotating shaft act as the rotor. Therefore, when the electromagnetic heater is working, the rotating shaft, auger, and electromagnetic coils rotate under the influence of the magnetic field inside the electromagnetic heater. The rotating auger agitates the oil inside the heating cylinder, increasing the uniformity of oil heating and promoting rapid flow of heated oil to prevent blockage. Furthermore, since the electromagnetic coils generate current under the influence of the magnetic field, and this current can only be dissipated as heat, the oil close to the augers can also be heated, improving the oil heating efficiency.

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.

[0017] Please see Figures 1-4An energy-saving zero-carbon heating device for an oilfield transportation system includes a support frame 1 and a heating cylinder 2. The heating cylinder 2 is fixedly installed at the top of the support frame 1. An oil inlet 3 is provided at the left end of the heating cylinder 2. An oil inlet connecting flange 4 is fixedly installed at the oil inlet 3. An oil inlet pipe 5 is fixedly connected to the heating cylinder 2 through the oil inlet connecting flange 4. A control valve 6 for controlling the flow of oil is provided on the oil inlet pipe 5. An oil outlet 7 is provided at the right end of the heating cylinder 2. An oil outlet connecting flange 8 is fixedly installed at the oil outlet 7. An oil outlet pipe 9 is fixedly connected to the heating cylinder 2 through the oil outlet connecting flange 8. Two symmetrically arranged electromagnetic heaters 10 are fixedly installed on the outer surface of the heating cylinder 2. A spiral device and a water bath heating device are provided inside the heating cylinder 2.

[0018] Please see Figures 2-3 The spiral device includes a fixed plate 15 for support, which is fixedly connected to the inner cavity side wall of the heating cylinder 2. A rotating shaft 17 for support is provided in the middle of the fixed plate 15. The fixed plate 15 ensures the stability of the rotating shaft 17 and ensures that the rotating shaft 17 is always kept in the middle of the inner cavity of the heating cylinder 2.

[0019] Please see Figures 2-4 The end of the rotating shaft 17 away from the fixed plate 15 is fixedly connected to a spiral auger 18 for guiding the flow of oil, ensuring that the spiral auger 18 is in the middle of the inner cavity of the heating cylinder 2. Then, the spiral auger 18 is used to guide the oil inside the heating cylinder 2, ensuring that the oil in the middle of the heating cylinder 2 can also move to the side wall of the heating cylinder 2, ensuring the uniformity of oil heating.

[0020] Please see Figures 2-3 The water bath heating device includes an isolation sleeve 11, which is fixedly connected to the inner wall of the heating cylinder 2. The isolation sleeve 11 and the inner wall of the heating cylinder 2 together form a filling cavity 12 for holding water. While the electromagnetic heater 10 heats the oil, it can also heat the water inside the filling cavity 12. Then, the hot water inside the filling cavity 12 is used to keep the oil warm, further reducing the internal temperature difference of the oil.

[0021] Please see Figure 2 The heating cylinder 2 has a through groove 13 inside its side wall for easy water flow. The outer surface of the heating cylinder 2 is fixedly installed at the through groove 13 for easy opening and closing of the water inlet 14. The water inlet 14 is connected to a sealing cap by a thread, which facilitates filling the filling cavity 12 with water and makes it easy to replace the water inside the filling cavity 12.

[0022] Please see Figure 3 The heating cylinder 2 is equipped with a rotating device, which includes a ball bearing 16, which is located inside the fixed plate 15.

[0023] Please see Figures 2-4 The inner ring sidewall of the ball bearing 16 is fixedly sleeved on the outer surface of the rotating shaft 17, and the outer ring sidewall of the ball bearing 16 is fixedly installed inside the fixed plate 15. The rotating shaft 17 is installed on the fixed plate 15 through the ball bearing 16, ensuring that the rotating shaft 17 can rotate relative to the fixed plate 15, so that the rotating shaft 17 rotates synchronously with the auger 18 when rotating.

[0024] Please see Figures 2-4 The rotating device also includes an electromagnetic coil 19 for driving. The electromagnetic coil 19 is fixedly installed inside the auger 18 and is located within the internal magnetic field range of the electromagnetic heater 10. This ensures that an electromagnetic effect is generated between the electromagnetic coil 19 and the internal magnetic field of the electromagnetic heater 10. The electromagnetic effect drives the rotating shaft 17 to rotate the auger 18, thereby agitating the oil through the rotating auger 18 and heating the oil evenly. The electromagnetic effect generated between the electromagnetic coil 19 and the electromagnetic heater 10 induces a current inside the electromagnetic coil 19. Since the induced current inside the electromagnetic coil 19 can only be dissipated as heat, the heat generated by the electromagnetic coil 19 can heat the oil in the middle of the heating cylinder 2, thereby reducing the internal temperature difference of the oil, avoiding flow velocity differences inside the oil, and improving the heating efficiency of the oil.

[0025] Working principle: In operation, the oil inlet pipe 5 is fixedly connected to the oil inlet 3 via the oil inlet connecting flange 4, and the oil outlet pipe 9 is fixedly connected to the oil outlet 7 via the oil outlet connecting flange 8. Oil is then introduced into the oil inlet pipe 5. The electromagnetic heater 10 is then turned on to heat the oil inside the heating cylinder 2. During this process, due to the design of the auger 18, the oil moves along the spiral direction of the auger 18, causing it to adhere to the side wall of the heating cylinder 2. The spiral design of the auger 18 guides the oil in the middle of the heating cylinder 2 towards the side wall, ensuring uniform heating without flow rate differences and improving heating efficiency. Simultaneously, water can be filled into the filling cavity 12 through the water inlet 14 and the through-slot 13. The electromagnetic heater 10 heats the water inside the filling cavity 12 while simultaneously heating the oil. The heated water in the filling cavity 12 keeps the oil inside the heating cylinder 2 warm, allowing the oil to... To maintain high fluidity, and secondly, because the auger 18 is equipped with an electromagnetic coil 19, an electromagnetic effect is generated between the electromagnetic coil 19 and the magnetic field inside the electromagnetic heater 10, forming a motor principle between the electromagnetic heater 10 and the electromagnetic coil 19. At this time, the electromagnetic heater 10 is the stator, while the electromagnetic coil 19 and the rotating shaft are the rotor. Therefore, when the electromagnetic heater 10 is working, the rotating shaft 17, the auger 18 and the electromagnetic coil 19 rotate under the action of the magnetic field inside the electromagnetic heater 10. At this time, the rotating auger 18 agitates the oil inside the heating cylinder 2, increasing the uniformity of oil heating and promoting the rapid flow of heated oil to prevent blockage. Furthermore, since the electromagnetic coil 19 generates current after being acted upon by the magnetic field, and the current generated by the electromagnetic coil 19 can only be dissipated in the form of heat, the oil close to the auger 18 can also be heated, improving the heating efficiency of the oil. After heating, the oil is discharged through the oil outlet pipe 9 for collection or continued transportation.
