[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0031] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0032] In the prior art, anti-freezing measures such as water jacket furnace heating are generally used to prevent pipeline freezing and blocking during gas well testing. However, due to the large size of the water jacket furnace heating device, it occupies a large ground space, and the heating area of the fluid pipeline in the furnace is small, resulting in unsatisfactory heating effect, which in turn leads to high operating costs and high maintenance costs of the water jacket furnace heating device. Therefore, the present application provides a heating pipeline assembly that can fully heat natural gas in a limited space to solve the above problems.
[0033] Example 1
[0034] In order to solve the problems existing in the prior art, an embodiment of the present application provides a heating pipeline assembly, such as Figures 1 to 5 As shown, it includes a first pipeline 1, both ends of the first pipeline 1 are blocked, and the side wall of the first pipeline 1 has an air inlet; a second pipeline 2, both ends of the second pipeline 2 are blocked, and the side wall of the second pipeline 2 has an air outlet; and at least two circulation pipelines 3, the circulation pipeline 3 is serpentine, and the two ends of the circulation pipeline 3 are respectively connected to the first pipeline 1 and the second pipeline 2, and the circulation pipeline 3 is used to connect with the heating component.
[0035] By blocking both ends of the first pipeline 1 and providing an air inlet on the side wall, natural gas or other gas to be heated is allowed to enter the first pipeline 1 accurately from a preset position and prevent gas leakage. The two ends of the circulation pipeline 3 are respectively connected to the first pipeline 1 and the second pipeline 2, so that after entering the circulation pipeline 3, the gas is heated through a serpentine path, and then converges to the second pipeline 2 and outputs through the outlet. The blocking of both ends of the first pipeline 1 and the second pipeline 2 can be welded and blocked by a plate structure.
[0036] In the embodiment of the present application, at least two circulation pipelines 3 adopt a serpentine design, which increases the flow path length of the gas in the pipeline, thereby increasing the contact time and contact area between the gas and the heating component, and can heat the gas more fully and evenly, greatly improving the heating efficiency. In addition, by setting up the serpentine circulation pipeline 3, the space utilization rate is high, and multiple heat exchanges can be achieved in a limited space, which not only meets the requirements of efficient heating, but also saves the space occupied by the equipment.
[0037] In some embodiments of the present application, the heating pipeline assembly further includes: a support 4, such as Figures 1 to 5 As shown, the first pipeline 1 and the second pipeline 2 are fixedly connected to the support 4 respectively, and the second pipeline 2 is arranged above the first pipeline 1 in the vertical direction.
[0038] The support 4 is used to support and fix the first pipeline 1 and the second pipeline 2 to enhance the structural stability of the entire heating pipeline assembly. The support 4 can be welded from pipes, plates or steel, and the specific structure is not limited.
[0039] By arranging the second pipeline 2 vertically above the first pipeline 1, the gas will naturally rise to the second pipeline 2 after entering the circulation pipeline 3 from the first pipeline 1 and being heated, and the flow path of the gas will be optimized by gravity, which is also conducive to the compact installation and space utilization efficiency of the heating pipeline assembly. And by arranging the first pipeline 1 with the air inlet at a lower position, it is conducive to docking with ground facilities or underground pipelines, reducing the complexity of pipeline layout and enhancing the convenience and adaptability of installation.
[0040] The first pipeline 1 and the second pipeline 2 are firmly connected by at least two connecting pipes arranged in the vertical direction. The two ends of the connecting pipe can be tightly fixed to the first pipeline 1 and the second pipeline 2 by welding. It is worth noting that the connecting pipe is not connected to the inside of the first pipeline 1 and the second pipeline 2, and its main function is to provide support. Specifically, the size of the first pipeline 1 and the second pipeline 2 is consistent, and the diameter of the connecting pipe is adapted thereto to achieve the best support effect. By adopting a hollow structure connecting pipe with the same diameter as the first pipeline 1 and the second pipeline 2, on the one hand, it can effectively support the two main pipelines and ensure the stability of the entire heating pipeline assembly structure; on the other hand, the hollow structure connecting pipe reduces the weight of the assembly, which helps to reduce material costs and the difficulty of handling and installation.
[0041] In some embodiments of the present application, the support 4 includes at least two supporting legs, each supporting leg has a bottom plate at the bottom, a surface of the bottom plate is provided with a plurality of through holes, and the bottom plate is used for detachable connection with the ground or other devices through the plurality of through holes.
[0042] The support 4 can more stably support and fix the first pipeline 1 and the second pipeline 2 by providing at least two supporting legs, reducing the risk of shaking or tipping caused by uneven load or external environmental factors. A plurality of through holes are provided on the surface of the bottom plate, which can be used for bolts, expansion screws or other fasteners to be detachably connected to the ground or other devices. As a result, the heating pipeline assembly can be quickly and conveniently installed, repositioned or dismantled for maintenance according to different work locations and needs, greatly improving the flexibility of use and reducing maintenance costs. The through holes on the bottom plate can be installed in a suitable manner according to the specific terrain. For example, in soft ground, the stability can be improved by driving deeper fasteners, or when installed on existing facilities, it can be closely connected with the existing structure, thereby improving the applicability of the heating pipeline assembly in various complex environments.
[0043] In some embodiments of the present application, the air outlet and the air inlet are arranged diagonally on a vertical plane. Figure 2 As shown, since the second pipeline 2 is arranged above the first pipeline 1 in the vertical direction, and the gas outlet and the gas inlet are arranged along the diagonal line on the vertical plane, the gas can smoothly enter each serpentine circulation pipeline 3 under the combined action of gravity and convection effect after flowing into the first pipeline 1 from the gas inlet, ensuring the uniform distribution and sufficient flow of the gas during the entire heating process. In this way, the maximum utilization of the gas circulation path is promoted in a limited space, thereby improving the heating efficiency.
[0044] Moreover, by arranging the air outlet and the air inlet along the diagonal line, the dead corners of gas retention during the flow process are effectively eliminated, the gas cooling speed and the probability of formation of local low-temperature areas are reduced, the pipeline is ensured to be unobstructed, and the freezing problem caused by condensate is avoided.
[0045] In some embodiments of the present application, Figure 4 As shown, at least two circulation pipelines 3 are arranged on the same side of the support 4, and the air outlet and the air inlet are arranged on the side facing away from the circulation pipeline 3.
[0046] Specifically, the first pipeline 1 has an air inlet and a first through hole connected to the circulation pipeline 3 processed on two side surfaces opposite to each other along its diameter direction. Similarly, the second pipeline 2 has an air outlet and a second through hole connected to the circulation pipeline 3 processed on two side surfaces opposite to each other along its diameter direction.
[0047] By arranging at least two circulation pipelines 3 on the same side of the support 4, the heat source can be concentrated, so that the heat is transferred to the circulation pipeline 3 more concentratedly, thereby improving the thermal efficiency and reducing the heat loss. By arranging the air outlet and the air inlet on the side facing away from the circulation pipeline 3, it is ensured that the heated gas will not immediately mix with the unheated gas or flow back to the air inlet after flowing out from the air outlet of the second pipeline 2, ensuring that the gas always flows along the set path, avoiding the ineffective circulation of heat energy. At the same time, this layout helps to simplify the structure, make full use of limited space, and facilitate installation and maintenance.
[0048] In some embodiments of the present application, the plane where the circulation pipeline 3 is located is arranged along the vertical direction, and at least two circulation pipelines 3 are arranged at intervals along the horizontal direction.
[0049] The plane where the circulation pipeline 3 is located is arranged in the vertical direction, and a three-dimensional layout is adopted, so that space resources can be better utilized, and the compact design can adapt to the limited installation space. And because the circulation pipeline 3 extends in the vertical direction, combined with the natural rise of gas, the heated gas can be more easily raised to the second pipeline 2, while the cold gas or the gas that is not fully heated automatically flows downward, forming a good natural convection.
[0050] The circulation pipeline 3 is distributed in the vertical plane, and combined with the fixing function of the support 4, the entire heating pipeline assembly has better stability when bearing gas pressure and its own weight, reducing structural deformation or damage caused by uneven force. By arranging the circulation pipeline 3 at intervals in the horizontal direction, a heating assembly can be arranged between two circulation pipelines 3, thereby increasing the contact area between the gas and the heating assembly, effectively improving the heat exchange efficiency, and ensuring that the gas can be fully and evenly heated.
[0051] In some embodiments of the present application, the two circulation pipelines 3 are respectively arranged near the blocked positions at both ends of the first pipeline 1, thereby reducing the stagnant area of gas during the flow process and reducing the risk of condensed water accumulation.
[0052] In some embodiments of the present application, the heating pipeline assembly also includes: an air inlet pipeline 5 and an air outlet pipeline 6, the air inlet pipeline 5 is connected to the first pipeline 1 through an air inlet, and the air outlet pipeline 6 is connected to the second pipeline 2 through an air outlet; the pipe mouth of the air inlet pipeline 5 has a first thread for adapting to the air inlet pipeline, and the pipe mouth of the air outlet pipeline 6 has a second thread for adapting to the air outlet pipeline.
[0053] The air inlet pipeline 5 is connected to the first pipeline 1 through the air inlet, and the air outlet pipeline 6 is connected to the second pipeline 2 through the air outlet, thereby determining the air flow direction and circulation path in the heating pipeline assembly, that is, the air inlet pipeline 5 is connected to the gas transmission pipeline, and the air outlet pipeline 6 is connected to the gas production tree valve. When the gas well is throttled on the ground, it is ensured that the gas enters from the air inlet pipeline 5 and is discharged from the air outlet pipeline 6 after being heated, thereby realizing an effective gas heating process. The first thread and the second thread are respectively provided at the pipe openings of the air inlet pipeline 5 and the air outlet pipeline 6, and the first thread and the second thread can be flat male threads, so that the external air inlet pipeline and the air outlet pipeline can be conveniently connected to the heating pipeline assembly through the threaded interface, which not only enhances the sealing performance, but also simplifies the assembly process, improves the convenience of installation and disassembly, and reduces the difficulty of operation and the failure rate. The heating pipeline assembly can select 42CrMo alloy steel as the pipeline material, which can ensure that the entire assembly maintains good performance and a long service life under harsh working conditions.
[0054] The heating pipeline assembly provided in Example 1 of the present application heats the gas by passing through at least two circulation pipelines 3, which can expand the heating area while reducing the occupied space and extend the heating time, thereby effectively solving the problem of the existing technology that not only the space occupied is large but the heating effect is poor, thereby reducing operating costs.
[0055] Example 2
[0056] The heating pipeline assembly provided in Example 2 of the present application is different from that in Example 1 in that another implementation method of the circulation pipeline 3 arrangement is provided.
[0057] In some embodiments of the present application, there are four circulation pipelines 3, and every two adjacent circulation pipelines 3 form a group, wherein the two circulation pipelines 3 in a group have a height difference in the vertical direction.
[0058] When the gas production well has a high output, the processing capacity can be improved by increasing the number of circulation pipelines 3. Figures 6 to 9 As shown, the circulation pipeline 3 is arranged on a vertical plane, and four circulation pipelines 3 are arranged side by side in the horizontal direction. In order to optimize heating efficiency and save equipment cost, two adjacent circulation pipelines 3 can be combined into a pair and present a height difference in the vertical direction, so that the two circulation pipelines 3 in the same group form a staggered layout in the vertical direction.
[0059] The vertical misalignment ensures that there is no direct obstruction between the front and rear rows of circulation pipelines 3, and heat can be freely transferred from the heating assembly to the rear pipeline, avoiding heat energy loss and ensuring that all circulation pipelines 3 can be fully heated. At the same time, the vertical misalignment setting also allows the multiple first through holes on the first pipeline 1 connecting each circulation pipeline 3 to maintain sufficient spacing, avoiding the mechanical strength of the pipeline being weakened due to too dense through holes, and the second pipeline 2 is similar, thereby ensuring the stability and durability of the entire heating pipeline assembly.
[0060] The heating pipeline assembly provided in Example 2 of the present application improves the processing capacity by increasing the number of circulation pipelines 3 according to the production of the gas well, and forms a staggered layout in the vertical direction through two circulation pipelines 3 in a group, thereby optimizing the heating efficiency and saving equipment costs, and ensuring the stability of the entire heating pipeline assembly.
[0061] Example 3
[0062] Embodiment 3 of the present application provides a heating device, including the heating pipeline assembly provided by Embodiment 1 and Embodiment 2 of the present application.
[0063] In some embodiments of the present application, the heating device further includes: a plurality of heating components, one heating component being able to cover at least the range of a circulation pipeline 3; and a device body, wherein the plurality of heating components and the heating pipeline components are all arranged inside the device body.
[0064] Since the heating pipeline assembly adopts a serpentine arrangement and a circulation pipeline 3 arranged in the vertical direction, the heating assembly can be closely attached to the side of the circulation pipeline 3 and can fully cover all parts thereof, ensuring that each circulation pipeline 3 can absorb heat evenly and fully, thereby greatly improving the heating efficiency and gas temperature consistency, and effectively avoiding the formation of local low temperature points and hydrates.
[0065] Multiple heating components can be flexibly matched with heating pipeline components according to actual conditions. For example, when there are two circulating pipelines 3, 2-3 heating components can be configured; when the number of circulating pipelines 3 increases to 4, the number of heating components increases to 4-6 accordingly to meet the anti-freezing and blocking needs under different gas well production and different ambient temperatures.
[0066] By integrating all heating components and heating pipe components into the integrated device body, not only the overall layout of the equipment is optimized and the floor space is reduced, but also the internal components are effectively protected from environmental factors by isolating the device body from the external environment, reducing heat loss and further improving the durability and stability of the heating device.
[0067] The design of the heating assembly is diverse, and may include, but is not limited to, common types such as heating tape wrapped around the circulation pipeline, heating wire, or thermal radiation heater. In view of the unstable power supply or the difficulty in obtaining high-power power supply at the well site, the heating assembly can use catalytic heating technology, such as catalytic heating pad products on the market. This type of device is based on the principle of catalytic oxidation of natural gas. Under low temperature conditions, the catalyst can promote the oxidation reaction of natural gas without open flames and efficiently release heat in the form of infrared radiation.
[0068] During operation, the catalytic heating pad is first preheated by an external power supply. After the preheating is completed, the power supply is cut off and replaced by the natural gas from the gas well itself. The natural gas starts a flameless combustion reaction after contacting the catalyst, and the heat generated is effectively transferred to the circulation pipeline 3, ensuring the continuous and stable heating effect of the system. This solves the energy supply problem, makes full use of on-site resources, and enhances the safety and self-sufficiency of the heating process.
[0069] In some embodiments of the present application, the heating device also includes: a flow detection device, which is provided at the air inlet and the air outlet of the heating pipeline assembly, and the flow detection device is used to detect the flow of the fluid passing through the air inlet and the air outlet; a control device, which is electrically connected to the heating assembly and the flow detection device, respectively, and the control device controls the power of the heating assembly through the detection signal of the flow detection device.
[0070] By installing flow detection devices at the air inlet and the air outlet, the device can capture and record the fluid flow data entering and leaving the heating pipeline assembly in real time and accurately. This allows the operator to timely analyze and determine whether there is a freezing problem caused by low temperature inside the heating pipeline assembly based on the actual flow change. Specifically, when it is detected that the fluid flow entering the heating pipeline assembly from the air inlet is significantly reduced compared to the flow flowing out from the air outlet, this is most likely due to freezing in certain parts of the interior, which hinders the normal circulation of the fluid. At this time, the control device closely linked to the flow detection device will respond quickly based on the received abnormal flow detection data, increase the power output of the heating assembly, and increase the temperature of the internal circulation pipeline 3 of the heating pipeline assembly, thereby effectively dissolving or preventing hydrate formation and relieving the freezing state, thereby improving the operating efficiency and reliability of the entire system.
[0071] The heating device provided in Example 3 of the present application successfully reduces the space occupied and improves the heating efficiency by adopting the heating pipeline assembly provided in Example 1 or Example 2. This optimization result directly leads to the effective reduction of operating costs, demonstrating the significant advantages of the heating device in terms of practicality, economy and space utilization.
[0072] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
