Description

Technical Field

[0001] This utility model relates to the field of hydrogenation reactors, specifically a rapid heat exchange fixed-bed continuous hydrogenation reactor. Background Technology

[0002] In chemical, energy, and other industrial sectors, hydrogenation reactors are crucial equipment used to conduct chemical reactions between hydrogen and raw materials to produce desired chemical products. During the hydrogenation reaction, the temperature inside the reactor continuously rises due to the exothermic reaction. To maintain stable reactor operation and ensure efficient reaction, effective heat exchange is necessary to control its internal temperature. Traditional heat exchange methods typically employ fixed heat exchangers, where heat is exchanged between the reactor medium and heat exchange tubes. However, this method has relatively low heat exchange efficiency and is insufficient for some high-efficiency, rapid reaction requirements. Especially when rapid temperature adjustment or handling large heat loads is needed, traditional heat exchange methods often fall short of ideal results. Therefore, we propose a rapid heat exchange fixed-bed continuous hydrogenation reactor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a rapid heat exchange fixed-bed continuous hydrogenation reactor, which solves the aforementioned problems.

[0005] A rapid heat exchange assembly, mounted on a base, is used for rapid heat exchange within the hydrogenation reactor.

[0006] Preferably, the heat exchange tubes are provided in several groups, and the several groups of heat exchange tubes are slidably inserted into the outside of the hydrogenation reactor.

[0007] Preferably, the bottom of the movable plate is equipped with rollers at the four corners, and the top of the base is provided with two sets of moving grooves corresponding to the bottom of the movable plate, with the rollers slidably connected in the moving grooves.

[0008] Preferably, the rapid heat exchange assembly includes an assembly frame, an end head, a rotating ring, a limiting ring, and a connecting frame. The top of the base is fixed with vertical assembly frames on both sides corresponding to the drive motor. The top of the two sets of assembly frames is fixed with an integrated end head. The output shaft of the drive motor is rotatably connected to a cross-shaped connecting frame. The end of the connecting frame is fixed with a ring-shaped rotating ring. The outer wall of the rotating ring is fixed with a limiting ring.

[0010] Preferably, the rapid heat exchange assembly further includes a main rod, a rocker arm, and a secondary rod. The top of the rotating ring is fixedly connected to the main rod, and the top of the moving plate is fixedly connected to the secondary rod corresponding to the side of the heat exchanger. One end of the rocker arm is rotatably sleeved on the outer wall of the main rod, and the other end of the rocker arm is rotatably sleeved on the outer wall of the secondary rod.

[0011] Compared with the prior art, this utility model provides a fast heat exchange fixed-bed continuous hydrogenation reactor, which has the following beneficial effects:

[0012] 1. This rapid heat exchange fixed-bed continuous hydrogenation reactor uses a drive motor to rotate the connecting frame, which in turn drives the rotating ring to rotate.

This continuous heat exchange method greatly increases the contact area and contact time between the heat exchange tube and the medium inside the hydrogenation reactor, thereby significantly improving the heat exchange efficiency.

[0013] 2. When the temperature of the hydrogenation reactor needs to be adjusted quickly or a large heat load needs to be handled, the rapid heat exchange component of this device can respond quickly. By increasing the sliding speed of the heat exchange tubes, rapid heat exchange is achieved, which helps to maintain the stable operation of the hydrogenation reactor. Attached Figure Description

[0028] Movable plate 3: Slidingly mounted on the top of base 1, corresponding to the side of hydrogenation reactor 2, for supporting and moving heat exchanger 4. Rollers 7 are rotatably mounted at the four corners of the bottom of movable plate 3 to ensure stability during sliding.

[0029] Heat exchanger 4: Slidingly mounted on the movable plate 3, with several sets of heat exchange tubes 5 fixed inside, used for heat exchange with the medium in the hydrogenation reactor 2. When the movable plate 3 slides, the heat exchanger 4 also moves accordingly, realizing dynamic heat exchange;

[0030] Heat exchange tube 5: It is fixed inside the heat exchanger 4 and slidably inserted outside the hydrogenation reactor 2. It is the main component of heat exchange. By sliding, it increases the contact area with the medium inside the reactor and improves the heat exchange efficiency.

[0031] Drive motor 6: Fixed on the top of the base 1, corresponding to the side of the moving plate 3, used to provide power to drive the connecting frame 16 to rotate, thereby driving the entire rapid heat exchange assembly to work;

[0032] Roller 7: Rotatably mounted on the bottom of the movable plate 3, and slidably connected to the movable groove 8 on the base 1 to ensure the stability and smoothness of the movable plate 3 during the sliding process;

[0033] Movable groove 8: It is located on the top of the base 1, below the movable plate 3, and is used to accommodate and guide the sliding of the roller 7 to ensure the accurate movement of the movable plate 3.

[0034] Sub-rod 9: Fixed to the top of the movable plate 3, corresponding to the side of the heat exchanger 4, used to receive the thrust transmitted by the main rod 14 through the rocker arm 15, and drive the movable plate 3 to slide.

[0035] Component frame 10: Fixed on the top of the base 1, corresponding to both sides of the drive motor 6, used to support and fix the end 11, and to provide a fulcrum for the rotation of the connecting frame 16;

[0036] End 11: integrally fixed with component frame 10, used for sliding installation of limit ring 13 to ensure the stability of rotating ring 12 during rotation;

[0037] Rotating ring 12: It is ring-shaped and fixed to the end of the connecting frame 16. A limit ring 13 is fixed to its outer wall. It rotates by rotating the connecting frame 16, thereby driving the main rod 14 to move.

[0038] Limiting ring 13: Slidably installed between the two sets of end caps 11 to ensure the stability and accuracy of the rotating ring 12 during its rotation;

[0039] Main rod 14: It is fixed to the top of the rotating ring 12 and moves with the rotation of the rotating ring 12. One end of the rocker arm 15 is rotatably sleeved on the outer wall, which converts the rotational motion into linear thrust.

[0040] Rocker arm 15: One end is rotatably sleeved on the outer wall of the main rod 14, and the other end is rotatably sleeved on the outer wall of the auxiliary rod 9. It is used to transmit the thrust of the main rod 14 to the auxiliary rod 9, thereby driving the moving plate 3 to slide.

[0041] Connecting frame 16: It is cross-shaped, with the bottom corresponding to the middle position and fixed to the output shaft of the drive motor 6. All four branches are fixed to the inner wall of the rotating ring 12. The rotation of the drive motor 6 drives the rotating ring 12 to rotate.

[0042] Working principle: When rapid heat exchange is required in the hydrogenation reactor 2, the drive motor 6 is started first. The output shaft of the drive motor 6 starts to rotate, which drives the connecting frame 16 fixed to it to rotate. The connecting frame 16 is cross-shaped, and its four branches are fixed to the inner wall of the rotating ring 12. Therefore, the rotation of the connecting frame 16 will drive the rotating ring 12 to rotate. The outer wall of the rotating ring 12 is fixed to the limiting ring 13. The limiting ring 13 is slidably installed between the two sets of ends 11. The ends 11 are integrally fixed to the component frame 10, and the component frame 10 is fixed to the top of the base 1. Therefore, the rotation of the limiting ring 13 between the two sets of ends 11 ensures the stability of the rotating ring 12 when it rotates. As the rotating ring 12 gradually rotates, the main rod 14 fixed to the top of the rotating ring 12 also begins to move. One end of the rocker arm 15 is rotatably sleeved on the outer wall of the main rod 14, and the other end of the rocker arm 15 is rotatably sleeved on the outer wall of the auxiliary rod 9. The auxiliary rod 9 is fixed to the top of the movable plate 3, corresponding to the side of the heat exchanger 4. When the main rod 14 transmits force to the auxiliary rod 9 through the rocker arm 15, the auxiliary rod 9 is pushed and drives the movable plate 3 to slide on the base 1. Rollers 7 are rotatably installed at the four corners of the bottom of the movable plate 3. Two sets of moving grooves 8 are opened at the top of the base 1 corresponding to the bottom of the movable plate 3. The rollers 7 are slidably connected in the moving grooves 8, thus ensuring the stability of the movable plate 3 during the sliding process. The heat exchanger 4 is slidably installed on the movable plate 3, so when the movable plate 3 slides, the heat exchanger 4 will also move accordingly. Several sets of heat exchange tubes 5 are fixed inside the heat exchanger 4. The heat exchange tubes 5 are slidably inserted into the outside of the hydrogenation reactor 2. During the process of the heat exchanger 4 sliding with the movable plate 3, the heat exchange tubes 5 will continuously slide inside the hydrogenation reactor 2, thereby realizing rapid heat exchange inside the hydrogenation reactor 2.
