Description

Technical Field

[0001] This utility model relates to the field of oil pipeline heating technology, and in particular to an energy-saving oil pipeline heating system. Background Technology

[0002] Currently, in the field of oil pipeline transportation, especially in cold regions or when transporting high-viscosity crude oil, pipeline heating is necessary to ensure smooth oil flow. Traditional heating systems often employ constant-power heating, resulting in high energy consumption and difficulty in flexibly adjusting heating efficiency according to actual needs. Typically, heating equipment is evenly distributed along the pipeline, but due to varying heat dissipation across different sections, some areas become overheated while others are underheated. Furthermore, existing heating systems lack effective heat recovery mechanisms during operation, causing some heat energy to be lost through pipeline heat dissipation, further increasing energy consumption. Construction personnel often face complex wiring and control issues when installing and maintaining heating devices, resulting in a significant workload, and the long-term stability of the equipment operation needs improvement.

[0018] The present invention relates to an energy-saving oil pipeline heating system, the specific implementation of which is as follows: (Combined with...) Figs. 1-2 The accompanying drawings are described in detail. Fig. 1 As shown, the overall structure of the system includes a main heating unit 1, a heat recovery module 2, and an intelligent control device 3. The components are fixedly connected by a bracket and their functional relationships are achieved through signal lines and conduits. The main heating unit 1 is the core component, and its structural design is as follows: Fig. 2 As shown, the system includes a heating chamber arranged axially along the oil pipeline. Within the heating chamber are several segmented heating coils 4. These heating coils 4 have an inner heat-conducting layer 5 made of graphene composite material with high thermal conductivity, which is tightly attached to the surface of the oil pipeline to facilitate heat transfer. The segmented heating coils 4 are connected to an intelligent control device 3 via independent temperature control modules. These temperature control modules are installed on the outside of the heating chamber and connected to a central processing unit 12 via wires, enabling precise control of the power output of each segmented heating coil 4.

[0019] The main heating unit 1 has a sliding mounting base 6 at its bottom. The sliding mounting base 6 consists of a base plate and two symmetrically arranged clamping blocks. The clamping blocks are fixed to the base plate with bolts. A rubber pad is provided on the inner side of the clamping blocks, directly contacting the surface of the oil pipeline to increase friction and ensure the stability of the main heating unit 1 after installation. The base plate of the sliding mounting base 6 has several positioning holes 15, which engage with positioning pins on the oil pipeline support. By inserting the positioning pins into the positioning holes 15, construction personnel can quickly install and disassemble the main heating unit 1, thus simplifying the operation process and improving construction efficiency.

[0020] The structure of heat recovery module 2 is as follows: Fig. 2 As shown, the system includes a heat exchange chamber 7 surrounding the main heating unit 1. Several heat pipes 8 are installed within the heat exchange chamber 7, with one end of each heat pipe 8 contacting the outer wall of the main heating unit 1 and the other end connected to a heat storage tank 9. The heat pipes 8 are filled with a phase change material to absorb the waste heat emitted by the main heating unit 1 and store the heat in the heat storage tank 9. A pressure relief valve 10 is located at the top of the heat storage tank 9. The pressure relief valve 10 is connected to the interior of the heat storage tank 9 via a spring mechanism. When the pressure inside the heat storage tank 9 exceeds a set value, the spring mechanism automatically opens the pressure relief valve 10 to release excess pressure, ensuring the safe operation of the system. A heat insulation coating 11, made of porous ceramic material, is applied to the outer surface of the heat exchange chamber 7 to reduce the impact of cold air on the heat exchange chamber 7 and minimize heat loss to the external environment.

[0021] The intelligent control device 3 includes a central processing unit 12 and several sensors 13. The sensors 13 are installed at various key locations in the oil pipeline, including the inlet, outlet, and different sections of the heating chamber. The sensors 13 are connected to the central processing unit 12 via signal lines to collect data such as oil temperature, flow rate, and ambient temperature in the pipeline in real time. The central processing unit 12 analyzes the collected data according to a preset algorithm and dynamically adjusts the power output of the segmented heating coils 4 to ensure that the heating process always matches the actual demand. The intelligent control device 3 also includes a wireless communication module 14, which connects to a remote monitoring terminal via a local area network. Construction personnel can view the operating status of the heating system in real time through the remote monitoring terminal and manually intervene or adjust parameters when necessary.

[0022] The specific operation process of this utility model is as follows: First, the construction personnel fix the main heating unit 1 to the oil pipeline using the sliding mounting base 6, and achieve rapid installation by utilizing the cooperation of the positioning hole 15 and the positioning pin; then, the heat recovery module 2 and the intelligent control device 3 are respectively fixed to the outside of the main heating unit 1 by the bracket, and the signal line and conduit are connected. After the work is completed, the system is started, and the sensor 13 begins to collect data such as oil temperature, flow rate and external ambient temperature in the pipeline, and transmits the collected data to the central processing unit 12. The central processing unit 12 analyzes the data according to the preset algorithm and dynamically adjusts the power output of the segmented heating coil 4. The segmented heating coil 4 adjusts the power output according to the temperature requirements of the area to avoid local overheating or insufficient heating. The heat-conducting layer 5 evenly transfers the heat generated by the segmented heating coil 4 to the surface of the oil pipeline, thereby achieving the heating of the oil.

[0023] During the heating process, the waste heat emitted by the main heating unit 1 is absorbed by the heat pipe 8 in the heat recovery module 2. The heat pipe 8 stores the heat in the heat storage tank 9 through a phase change material. The stored heat can be used for subsequent auxiliary heating or insulation operations, thereby reducing energy waste. The heat insulation coating 11 on the outside of the heat exchange chamber 7 effectively isolates the influence of cold air from the outside and reduces the loss of heat energy to the external environment, improving the overall system's thermal efficiency. When the pressure inside the heat storage tank 9 exceeds the set value, the pressure relief valve 10 automatically opens to release excess pressure, ensuring the safe operation of the system.

[0024] The application of this invention is particularly prominent in cold regions or in scenarios involving the transportation of high-viscosity crude oil. For example, in low-temperature environments during winter, the crude oil in pipelines may experience reduced fluidity due to excessively low temperatures, leading to transportation difficulties. In this case, this invention uses an intelligent control device 3 to monitor the oil temperature in the pipeline in real time and dynamically adjust the power output of the segmented heating coil 4 to ensure that the crude oil always maintains a suitable flow temperature. At the same time, the heat recovery module 2 effectively recovers the waste heat emitted by the main heating unit 1, further reducing energy consumption. When maintenance is required, construction personnel can quickly disassemble the main heating unit 1 through the sliding mounting base 6 and remotely monitor the system status using the wireless communication module 14 to promptly identify and resolve problems, thereby improving maintenance efficiency.

[0025] The above detailed embodiments describe the structural composition and operating principle of this utility model, fully disclosing the connection relationship, positional relationship and mutual cooperation relationship between the components, so that those skilled in the art can implement the technical solution according to the contents of the specification, and meet the requirements of the patent law for full disclosure.

[0026] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0027] During oil pipeline transportation in cold regions, crude oil's fluidity decreases significantly due to low temperatures, leading to transportation difficulties. In this case, construction workers first fix the main heating unit 1 to the oil pipeline using a sliding mounting base 6. The base plate of the sliding mounting base 6 is fixed to the clamping block with bolts. The rubber pad on the inner side of the clamping block directly contacts the surface of the oil pipeline to increase friction and ensure the stability of the main heating unit 1. Simultaneously, the positioning holes 15 on the base plate engage with positioning pins on the oil pipeline support, allowing construction workers to quickly install the unit by inserting the positioning pins into the positioning holes 15. This operation simplifies the installation process and improves construction efficiency.

[0028] Subsequently, the heat recovery module 2 and the intelligent control device 3 are fixed to the outside of the main heating unit 1 via brackets, and the signal lines and conduits are connected. After the system starts, the sensor 13 begins to collect data such as oil temperature, flow rate, and ambient temperature in the pipeline, and transmits this data to the central processing unit 12. The central processing unit 12 analyzes the data according to a preset algorithm and dynamically adjusts the power output of the segmented heating coil 4. For example, at the pipeline inlet, because the crude oil temperature is lower, the power output of the segmented heating coil 4 is higher; while at the pipeline outlet, because the crude oil has been heated to a suitable temperature, the power output is correspondingly reduced. This segmented control method avoids local overheating or underheating, significantly improving heating efficiency.

[0029] The heat generated by the segmented heating coil 4 is transferred to the surface of the oil pipeline through the heat-conducting layer 5. The heat-conducting layer 5 is made of graphene composite material with high thermal conductivity, which can evenly distribute heat on the pipeline surface, thereby improving heating efficiency and reducing energy loss. During this process, the waste heat emitted by the main heating unit 1 is absorbed by the heat pipe 8 in the heat recovery module 2. The phase change material filled inside the heat pipe 8 stores the heat in the heat storage tank 9. This stored heat can be used for subsequent auxiliary heating or insulation operations, further reducing energy consumption. The heat insulation coating 11 on the outside of the heat exchange chamber 7 is made of porous ceramic material, covering the entire outer surface, effectively isolating it from the influence of cold air and reducing heat loss to the external environment, thereby improving the overall system's thermal utilization rate.

[0030] When the pressure inside the heat storage tank 9 exceeds the set value, the pressure relief valve 10 automatically opens via a spring mechanism to release excess pressure and ensure the safe operation of the system. Simultaneously, the wireless communication module 14 in the intelligent control device 3 connects to a remote monitoring terminal via a local area network. Construction personnel can view the real-time operating status of the heating system through the remote monitoring terminal and manually intervene or adjust parameters when necessary. This remote monitoring function not only improves the controllability of the system but also facilitates timely detection and resolution of problems.

[0031] In actual operation, if a section of the pipeline experiences insufficient heating due to a sudden drop in external ambient temperature, sensor 13 will quickly detect the temperature change in that area and transmit the data to the central processing unit 12. The central processing unit 12 will calculate the required increase in power output based on a preset algorithm and adjust the power of the corresponding segmented heating coils 4 via the temperature control module, thereby quickly restoring the heating effect in that area. This process demonstrates the system's intelligence and efficiency.

[0032] Furthermore, during maintenance, workers can quickly disassemble the main heating unit 1 using the sliding mounting base 6. For example, if a segmented heating coil 4 malfunctions, workers only need to loosen the bolts of the clamping block to remove the main heating unit 1 for repair or replacement. This design significantly reduces maintenance difficulty and workload.

[0033] In summary, this utility model, through the synergistic effect of the segmented heating coil 4, the intelligent control device 3, and the heat recovery module 2, achieves precise distribution of heating power and effective recovery of waste heat, significantly reducing energy consumption. Simultaneously, the design of the sliding mounting base 6 and the wireless communication module 14 simplifies the installation and maintenance process, improving the system's reliability and stability. The above description details the connection relationships, positional relationships, and mutual cooperation relationships between the various components, enabling those skilled in the art to implement the technical solution based on the description, thus meeting the patent law's requirement of full disclosure.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
