Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial heating and temperature control technology, and in particular to a dual-heat-source, multi-loop, dual-temperature-position heat transfer oil heating system. Background Technology
[0002] In the field of industrial heating, traditional thermal oil heating systems often suffer from problems such as low energy efficiency, inaccurate temperature control, and significant safety hazards. Temperature control is a crucial aspect of industrial production and processing, directly impacting product quality and production efficiency. Traditional heating systems typically employ a single heat source and single-loop design. While this design meets basic heating needs to some extent, it has gradually revealed several problems in practical applications.
[0003] First, the design of a single heat source limits the flexibility and adaptability of the heating system. In industrial production scenarios with varying temperature requirements, traditional systems often struggle to achieve precise temperature control, leading to energy waste and low heating efficiency. Furthermore, when the heat source fails, the entire heating system will be paralyzed, severely impacting the continuity and stability of production.
[0004] Secondly, the single-loop design makes it easy for temperature gradients to form in the heat transfer oil during circulation, leading to uneven heating. This not only affects the heating quality of the product but may also accelerate the aging of the heat transfer oil and the wear of the equipment, increasing maintenance costs and safety hazards.
[0005] To address these issues, industry has begun exploring more efficient, flexible, and safe heating systems. Among these, the dual-heat-source, multi-loop, dual-temperature-level thermal oil heating system, as an innovative solution, has gradually gained attention. This system introduces two independent heat sources, enabling flexible responses to different temperature requirements; simultaneously, the multi-loop design allows the thermal oil to circulate within different temperature ranges, effectively avoiding temperature gradient problems and improving heating uniformity and efficiency.
[0006] However, despite the numerous advantages of dual-heat-source, multi-loop, dual-temperature-position thermal oil heating systems, several technical challenges remain in practical applications. These include ensuring coordinated operation between the two heat sources to achieve precise temperature control of the thermal oil, and guaranteeing system safety and stability. Therefore, in-depth research and optimization of dual-heat-source, multi-loop, dual-temperature-position thermal oil heating systems are of significant practical importance and application value.
[0007] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a dual-heat-source, multi-loop, dual-temperature-position heat transfer oil heating system. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] Please see Figure 1 A dual-heat-source, multi-loop, dual-temperature-position thermal oil heating system, comprising:
[0034] First heat source 1 and second heat source 2 are arranged side by side. Both first heat source 1 and second heat source 2 are organic heat carrier heating furnaces. First heating pipe 3 and second heating pipe 4 are respectively provided at the heat transfer oil outlet positions of first heat source 1 and second heat source 2 to output heated heat transfer oil.
[0035] The main loop pipe 5 is used to connect the circulation loop of the heat transfer oil to transport the heat transfer oil output after heat exchange between the high-temperature user and the low-temperature user back to the first heat source 1 and the second heat source 2 for circulation heating. The heat transfer oil output after heat exchange between the high-temperature user and the low-temperature user has residual heat and can be reused. When it returns to the first heat source 1 and the second heat source 2 for reheating, the energy loss of the first heat source 1 and the second heat source 2 is reduced.
[0036] The main heating pipeline 6, the first heating pipeline 3, and the second heating pipeline 4 are connected and converge at the input end of the main heating pipeline 6. The output end of the main heating pipeline 6 is divided into the third heating pipeline 7 and the fourth heating pipeline 8 to transport heat transfer oil to high-temperature users and low-temperature users respectively. The first heat source 1 and the second heat source 2 output heat transfer oil to the main heating pipeline 6 through the first heating pipeline 3 and the second heating pipeline 4. The first heat source 1 and the second heat source 2 can supply heat independently or jointly. Furthermore, the first heat source 1 and the second heat source 2 can output heat transfer oil at different temperatures, thus making temperature output control more direct and efficient. Under the combined temperature heating control, temperature regulation can be more precise to achieve precise heating.
[0037] The circulation volume regulating mechanism is installed on the main heating pipeline 6 to passively regulate the circulation volume of oil based on the oil pressure. The circulation volume regulating mechanism is equivalent to an intermediate oil pressure control area. After regulating the oil pressure, the output is made so that the output oil pressure and temperature are accurate.
[0038] The system includes a first circulation pipe 9 and a second circulation pipe 10. The first circulation pipe 9 transports the heat transfer oil output by the high-temperature user back to the main loop pipe 5, and the second circulation pipe 10 transports the heat transfer oil output by the low-temperature user back to the main loop pipe 5. The heat transfer oil output by the high-temperature user and the low-temperature user after heat exchange has residual heat and can be reused. Therefore, the heat transfer oil with residual heat is automatically sent back to the main loop pipe 5 through the first circulation pipe 9 and the second circulation pipe 10 to transport the heat transfer oil back to the first heat source 1 and the second heat source 2 to achieve recycling.
[0039] Furthermore, a first replenishment pipe 11 and a second replenishment pipe 12 are respectively installed at the heat transfer oil return port on the first heat source 1 and the second heat source 2 to replenish the heat transfer oil to the mechanical heat carrier heating furnace of the first heat source 1 and the second heat source 2. In conjunction with the oil pressure control equipment such as the organic heat carrier expansion tank, heat transfer oil is provided to the first heat source 1 and the second heat source 2 to ensure a complete oil supply.
[0040] Furthermore, a high-low temperature direct pipeline 13 connects the output end of the high-temperature user and the input end of the low-temperature user to directly transport the heat transfer oil output by the high-temperature user after heat exchange to the low-temperature user for reuse. This is equivalent to the heat transfer oil at the output end of the high-temperature user being directly reused at the low-temperature user. This circuit forms a direct and efficient heat transfer, improves heating efficiency, and reduces the burden on the heating circuit.
[0041] Furthermore, the circulation volume regulating mechanism includes a flow measurement pipe 14, which is connected to the main heating pipe 6 so that the heat transfer oil in the main heating pipe 6 is transported after the oil pressure is regulated by the circulation volume regulating mechanism.
[0042] Furthermore, a flow sensor is installed on the flow measurement pipe 14 to detect the flow rate and then regulate the heat transfer oil circulation flow rate.
[0043] Furthermore, a regulating pipe 15 is connected between the flow measurement pipe 14 and the main loop pipe 5. When the flow sensor on the flow measurement pipe 14 detects that the heat transfer oil supply flow is too large, a portion of the heat transfer oil in the main heating pipe 6 is diverted through the regulating pipe 15, returning it to the main loop pipe 5, and then back to the first heat source 1 and the second heat source 2 to complete the cycle. The high-temperature heat transfer oil returning to the first heat source 1 and the second heat source 2 reduces the energy consumption of the first heat source 1 and the second heat source 2, saving energy consumption while effectively regulating the heat transfer oil circulation flow of the heating system.
[0044] In summary, compared with the prior art, the dual-heat-source, multi-loop, dual-temperature-position thermal oil heating system of this utility model has the following significant advantages:
[0045] High efficiency and energy saving: Through a dual heat source design and multi-loop circulation, the system can make full use of energy and improve heating efficiency. At the same time, dual-temperature control technology allows the system to adjust the heat transfer oil temperature according to actual needs, further reducing energy waste.
[0046] Precise control: Integrating advanced sensors and controllers, the system can monitor and control the temperature of the heat transfer oil in real time, ensuring the stability and accuracy of the heating process. This helps improve product quality and production efficiency.
[0047] High flexibility: The dual heat source and multi-loop design enables the system to flexibly respond to the temperature requirements of different industrial production scenarios. When one heat source or loop fails, the system can automatically switch to the backup heat source or loop, ensuring the continuity and stability of production.
[0048] Safe and reliable: The application of multiple safety safeguards makes the system more secure during operation. Even in the event of anomalies, the system can take timely measures to prevent accidents from occurring.
[0049] In summary, this utility model provides a dual-heat-source, multi-loop, dual-temperature-position thermal oil heating system, offering an efficient, precise, flexible, and safe solution for industrial heating. The promotion and application of this system will help improve the overall level and competitiveness of industrial production.
