Description

Technical Field

[0001] This utility model relates to the field of heat medium temperature control technology, specifically a temperature control system. Background Technology

[0002] In modern chemical, biopharmaceutical, and new energy material production processes, the reactor, as the core reaction vessel, directly determines product quality and production efficiency through the accuracy and stability of its temperature control. Traditional temperature control units mostly employ control strategies based on fixed parameters, which, while meeting basic constant temperature requirements, reveal significant technical limitations under complex operating conditions.

[0003] On the one hand, traditional temperature control systems rely on a single heat source input mode, controlling heating power through simple open-loop adjustment or fixed parameter settings, lacking a dynamic response mechanism to the temperature of the heat transfer medium. For example, in polymer polymerization reactions, the rate of heat release changes nonlinearly, making it difficult for traditional systems to track temperature gradient changes in real time. This often leads to overheating or underheating of the heat transfer medium. Most systems only adjust the heating power to raise the temperature, while cooling relies on passive heat exchange with external cooling water. The heat transfer medium itself cannot be recycled, resulting in low energy cascade utilization efficiency.

[0004] On the other hand, existing temperature control systems generally adopt a unidirectional circulation architecture. The heat medium is delivered to the reactor in one direction by the oil supply pump and then flows back to the storage tank, forming a closed linear flow path. This unidirectional flow easily leads to the formation of a temperature gradient in the reactor, with the temperature being higher near the inlet and lower further away from the inlet. This is especially prominent in large-volume or multi-layer coil reactors. Furthermore, the heat medium does not interact with subsequent process units during the reflux process, and a large amount of waste heat is not effectively recovered. In particular, in intermittent production mode, frequent start-ups and shutdowns cause the heat medium to repeatedly heat up and cool down. Utility Model Content

[0044] The purpose of this design is to provide a temperature control system that includes a circulating heat medium inlet pipeline, a circulating heat medium return pipeline, and a heat exchange pipeline. On one hand, it transfers the heat medium from the circulating heat medium inlet pipeline to the heat exchange pipeline and then to the target equipment, allowing the heat source to transfer cold or hot energy according to the temperature process requirements of the target equipment, thus achieving the process requirements of the controlled object. On the other hand, it provides a return structure that allows the heat medium to return to the heat source, thereby recovering waste heat to a certain extent and avoiding energy waste.

[0045] Furthermore, in this embodiment, a specific structure of the circulating heat medium input pipeline in a temperature control system is provided, wherein the circulating heat medium input pipeline includes a first control valve 14, a first three-way regulating valve 2, a circulating pump 3, a second three-way regulating valve 4, and a second control valve 15;

[0046] One end of the first control valve 14 is connected to the oil supply pipeline of the oil supply station, and the other end of the first control valve 14 is connected to the input end of the first three-way regulating valve 2 through the first heat medium input pipeline 10.

[0047] One output end of the first three-way regulating valve 2 is connected to the circulating pump 3 through the second heat medium input pipe 11;

[0050] The other end of the second control valve 15 is connected to the oil pipeline of the target equipment.

[0051] The purpose of this design is that the first and second control valves control the entry and exit of the heat medium into the input and output pipelines, respectively. The first three-way regulating valve can adjust the flow direction of the heat medium, with most of it flowing along the circulating heat medium input pipeline and a small portion overflowing and adjusting to the circulating heat medium return pipeline. The designed circulating pump provides the necessary power to the heat medium, enabling it to flow throughout the entire working section. The second three-way regulating valve can adjust the flow direction of the heat medium, with a portion flowing along the circulating heat medium input pipeline. When needed, it can direct the heat medium to the heat exchange pipeline, and after completing the heat exchange, it returns to the circulating heat medium input pipeline.

[0052] In this embodiment, a specific structure of a circulating heat medium return pipeline is provided, including a third control valve 16 and a fourth control valve 17.

[0053] One end of the fourth control valve 17 is connected to the output pipe of the target device, and the other end of the fourth control valve 17 is connected to one end of the third control valve 16 through the return pipe 20.

[0054] The other end of the third control valve 16 is connected to the oil supply station.

[0056] Meanwhile, in this embodiment, the heat exchange pipeline includes a heat exchange tank 8, which is equipped with a heat exchange coil and is filled with coolant. The inlet end of the heat exchange tank 8 is connected to the coolant inlet pipe 26, and the outlet end of the heat exchange tank 8 is connected to the coolant outlet pipe 27.

[0057] One end of the heat exchange coil is connected to the other output end of the second three-way regulating valve 4 through the fifth heat medium input pipe 23, and the other end of the heat exchange coil is connected to the fourth heat medium input pipe 13 through the sixth heat medium input pipe 24.

[0058] The purpose of this design is to regulate the temperature of the heat medium through the heat exchange tank in the heat exchange pipeline. It should be noted that the heat exchange tank is an existing structure. Those skilled in the art can choose an existing heat exchange tank in specific implementation. Its basic structure includes a cavity that can contain coolant and a sealed pipe. The coolant in the cavity is discharged through the coolant inlet pipe and the coolant outlet pipe and circulated to remove heat. The sealed pipe is connected to the heat medium inlet pipe, so that the heat medium can flow in it, thereby exchanging heat with the coolant and achieving cooling.

[0059] like Figure 3As shown, in some application scenarios, to achieve intelligent PID control, a PID controller 5, a first temperature sensor 1, a second temperature sensor 6, and a third temperature sensor 7 can be added to the above temperature control system. The first temperature sensor 1 is used to collect the temperature data of the heat transfer medium on the fuel supply station side, the second temperature sensor 6 is used to collect the temperature of the heat transfer medium on the output side of the circulating heat transfer medium input pipeline, and the third temperature sensor 7 is used to collect the temperature of the thermistor on the input side of the circulating heat transfer medium return pipeline. Thus, based on the hardware structure provided in this embodiment, and with the PID controller, in specific application scenarios, the fuel supply station acts as a heat source providing the heat transfer medium, the first temperature sensor detects the temperature provided by the fuel supply station, and the temperature is adjusted through the first three-way valve. A throttle valve regulates the flow of hot oil to provide a heat source for the reactor. A circulating pump exchanges energy between the hot oil and the reactor to provide circulation power. When the reactor needs to be cooled, a second electric regulating valve adjusts the flow of hot oil to enter the cooling heat exchanger and exchange heat with cooling water to achieve the purpose of cooling. A second temperature sensor detects the outlet oil temperature to provide a heating or cooling signal, and a third temperature sensor detects the return oil temperature. Comparing the return oil temperature with the outlet temperature can detect whether the system pipeline is unobstructed. The PID controller compares the actual temperature fed back by the outlet oil temperature with the target temperature, and outputs a signal to the first electric three-way regulating valve or the second electric regulating valve through PID logic calculation, forming a closed-loop control system to achieve precise temperature control.
