Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a bidirectional circulating buffer temperature control structure for a multi-stage reaction vessel. Background Technology

[0002] The bidirectional circulating buffer temperature control structure for multi-stage reactors is a temperature control device applied in multi-stage reactors. Through specific structural design and circulation mechanism, it achieves precise control of the material temperature inside the reactor to meet the stringent temperature requirements of chemical reactions at different stages. Simultaneously, it buffers temperature changes, reduces temperature fluctuations, and improves reaction stability and product quality.

[0003] A multistage reactor refers to a reaction device composed of multiple reactors connected in series or parallel. The reactors work together to allow the chemical reaction to proceed in stages. Compared to a single-stage reactor, a multistage reactor can more precisely control reaction conditions, improving reaction conversion and selectivity. It is widely used in industries such as chemical engineering, pharmaceuticals, and food processing, where high precision and efficiency are required.

[0004] Specifically, multistage reactors, with their segmented control of the reaction process, occupy a crucial position in many chemical reaction processes. However, current temperature control structures used in the actual use of multistage reactors have revealed numerous shortcomings, resulting in unsatisfactory overall temperature control. Most traditional temperature control structures rely on a simple jacket design, adjusting the reactor temperature by introducing hot or cold media into the jacket. However, this method has serious limitations in practical applications. The heat exchange efficiency between the jacket and the materials inside the reactor is low; the use of a single circulation control results in slow heat transfer; and when rapid heating or cooling is required during the reaction, it is difficult to reach the preset temperature in a short time, severely delaying the reaction process.

The heat exchange efficiency between the jacket and the materials inside the reactor is low; the use of a single circulating control results in slow heat transfer; and when rapid heating or cooling is required during the reaction, it is difficult to reach the preset temperature in a short time, severely delaying the reaction process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5The present invention provides the following technical solution: a bidirectional circulating buffer temperature control structure for a multi-stage reactor, including a reactor 1 and a controller 2 installed on the surface of the reactor 1. A jacket 3 is installed on the outer side wall of the reactor 1. A cold liquid pipe valve 4 is installed on the top side of one side of the jacket 3, and a hot liquid pipe valve 5 is installed on the bottom side of one side of the jacket 3.

[0025] A connecting pipe 6 is connected to the docking end of the hydrothermal pipe valve 5, and a buffer tank 7 is connected to the other end of the connecting pipe 6. A circulating pump 8 is installed at the top of the buffer tank 7. A docking clamp 9 is connected to the top of the jacket 3. An assembly clamp 10 is connected to one side of the docking clamp 9. A docking plate 11 is connected to the docking end of the assembly clamp 10. A rotating shaft 12 is connected to the inner wall of the opening of the docking plate 11. A threaded rod 13 is rotatably connected to the surface of the rotating shaft 12. A nut 14 is connected to the surface of the threaded rod 13. When the temperature inside the reactor 1 changes due to the exothermic or endothermic chemical reaction, the temperature sensor transmits the signal to the control system. The control system adjusts the working state of the heat exchanger according to the temperature deviation, and at the same time, utilizes the buffering effect of the buffer tank 7 to make the temperature change of the heat medium more stable. For example, when the temperature inside the reactor 1 rises, the circulating pump 8 increases heat exchange with the cold source to lower the temperature of the heat medium. At the same time, the lower-temperature heat medium in the buffer tank 7 enters the circulation system to absorb the heat inside the reactor and slow down the rate of temperature rise. Conversely, when the temperature drops, the circulating pump 8 increases heat exchange with the heat source to raise the temperature of the heat medium. The higher-temperature heat medium in the buffer tank 7 is replenished into the circulation system to prevent the temperature from dropping excessively.

[0026] Preferably, the jacket 3 has a hollow structure, and a temperature sensor is installed on the surface of the reactor 1. The buffer tank 7 and the circulating pump 8 are both electrically connected to the controller 2. In actual use, by using the temperature sensor, it is convenient to monitor the temperature inside the reactor 1 in real time and feed it back to the controller 2. Then, the circulating pump 8 is driven to transport the medium to the cold liquid pipe valve 4 and the hot liquid pipe valve 5, thereby facilitating precise bidirectional circulation temperature control of the internal temperature of the reactor 1.

[0027] Preferably, the inner wall curvature of the docking clamp 9 and the assembly clamp 10 matches the surface curvature of the reactor 1, and both the docking clamp 9 and the assembly clamp 10 are made of stainless steel.

[0028] Preferably, the threaded rod 13 rotates and engages with the opening on one side of the docking clamp 9, and then is threadedly connected to the nut 14. In actual use, by threading the nut 14 to the threaded rod 13, it is convenient to assemble and stabilize the docking clamp 9 and the assembly clamp 10, thereby facilitating the stable installation of the sleeve 3 on the surface of the controller 2.

[0029] Preferably, a hinge 15 is connected to one side of the controller 2, and a protective cover 16 is connected to the other side of the hinge 15. The protective cover 16 is made of transparent PVC material. In actual use, the use of the protective cover 16, made of transparent PVC material, facilitates real-time monitoring of the controller 2. In addition, the protective cover 16 protects the control components on the surface of the controller 2, ensuring the safety of the controller 2 operation.

[0030] Preferably, a side plate 17 is connected to the side of the protective cover 16 opposite to the hinge 15, and a stainless steel retaining plate 18 is connected to one side of the side plate 17. A retaining seat 19 is connected to the side of the controller 2 near the retaining plate 18. In actual use, the protective cover 16 is easily assembled on one side surface of the controller 2 by engaging and mating the retaining plate 18 and the retaining seat 19.

[0031] Preferably, a magnet 20 is installed on the side of the controller 2 near the card holder 19, and the magnet 20 is magnetically connected to the card plate 18. In actual use, the stainless steel card plate 18 on one side of the protective cover 16 is magnetically attracted to the magnet 20, thereby facilitating the stable installation of the protective cover 16.

[0032] The working principle of this utility model is as follows: The docking clamp 9 is assembled on the surface of the reactor 1, which in turn drives the jacket 3 to be assembled on the surface of the reactor 1. Then, the threaded rods 13 at both ends of the assembly clamp 10 are rotated along the rotating shaft 12. The threaded rods 13 are then engaged with the openings at both ends of the docking clamp 9. Finally, the nut 14 is threadedly connected to the threaded rod 13, facilitating the quick installation of the jacket 3 on the surface of the reactor 1. At this time, the cold liquid valve 4 and hot liquid valve 5 on the surface of the jacket 3 are respectively connected to the medium source. When the reaction occurs inside the reactor 1, the temperature sensor at the top of the reactor 1 monitors the internal temperature of the reactor 1 in real time. If necessary, additional temperature sensors can be added. When hot, the circulating pump 8 controls the rapid replenishment of the hot medium inside the buffer tank 7. When cooling is required, the circulating pump 8 controls the rapid replenishment of the cold medium inside the buffer tank 7, thereby achieving bidirectional circulating temperature control inside the reactor 1 and improving the precise temperature control effect inside the reactor 1. In addition, by rotating the protective cover 16 along the hinge 15, the locking plate 18 on one side of the protective cover 16 is engaged with the locking seat 19. Then, the locking plate 18 is magnetically attracted to the magnet block 20, and the protective cover 16 is then installed stably. At this time, the protective cover 16 protects the control elements on the surface of the controller 2, ensuring the safety of the controller 2 operation.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
