Description

Technical Field

[0001] This utility model relates to the field of catalyst regeneration technology, and in particular to a pentafluoroethane catalyst regeneration device. Background Technology

[0002] The catalyst commonly used in the production of pentafluoroethane is tri-n-butylamine. After long-term use, it will be deactivated due to chemical reaction with the reactants, forming complexes, oligomers or polymers. In order to reuse the pentafluoroethane catalyst, a regeneration device is needed to regenerate it.

[0003] There are many methods for regenerating pentafluoroethane catalysts, such as cleaning methods (solvent cleaning, acid washing, or alkali washing), thermal regeneration methods (low-temperature heat treatment, high-temperature calcination), and adsorbent treatment methods (using adsorbents, ion exchange resins, etc.). During high-temperature calcination, many harmful gases are generated. When the heating chamber is depressurized, these harmful gases enter the air, polluting the air environment and potentially being inhaled by workers, affecting their health. This reduces the practicality of the device during use. Therefore, this invention proposes a pentafluoroethane catalyst regeneration device to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a pentafluoroethane catalyst regeneration device, which solves the problem that in the prior art, a lot of harmful gases are generated during high-temperature roasting, and when the heating chamber is depressurized, these harmful gases are released into the air, polluting the air environment and potentially being inhaled by workers, affecting their health.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a pentafluoroethane catalyst regeneration device, including a heating chamber, a door hinged to the front end of the heating chamber, heating wires installed on both sides inside the heating chamber, multiple placement plates installed inside the heating chamber, the multiple placement plates being connected by connecting rods, a power mechanism provided at the top of the heating chamber, and an automatic pressure relief mechanism provided on one side of the heating chamber;

[0006] The automatic pressure relief mechanism includes a fixed cavity, an air outlet cavity, a purification cavity, an adsorption plate, a piston, a movable plate, a telescopic spring, and a transmission structure. The fixed cavity is installed on one side of the heating cavity, and an air outlet cavity is installed at the top of the fixed cavity. The purification cavity is installed on one side of the top of the heating cavity, and an adsorption plate is detachably installed inside the purification cavity. One end of the air outlet cavity is connected to one side of the purification cavity through a pipe. The movable plate is installed inside the fixed cavity, and a telescopic spring is installed on one side of the movable plate. A piston is installed at one end of the telescopic spring.

[0007] A further improvement is that the transmission structure includes a threaded groove, a threaded rod, a rotating wheel, and a limiting structure. The threaded groove is opened at both ends on one side of the fixed cavity. A threaded rod is installed through the inside of the threaded groove. One end of the threaded rod is rotatably connected to one side of the movable plate, and a rotating wheel is installed on the other side of the threaded rod.

[0008] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened at the bottom inside the fixed cavity, and the limiting block is provided inside the limiting groove. The top end of the limiting block is connected to the bottom end of the movable plate.

[0009] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0010] A further improvement is made in that: the power mechanism includes a mounting cavity, a servo motor, a drive gear, and a driven gear. The mounting cavity is installed at the top of the heating cavity. The servo motor is installed at the top of the mounting cavity. The drive gear is installed on one side inside the mounting cavity. The output end of the servo motor is connected to one end of the drive gear. The driven gear meshes with one side of the drive gear. The bottom end of the driven gear is connected to the top of the connecting rod.

[0011] A further improvement is that the cross-section of the driving gear is smaller than that of the driven gear, and the driving gear drives the driven gear to perform a deceleration motion.

[0012] The beneficial effects of this utility model are as follows: By setting an automatic pressure relief mechanism on one side of the heating wire, the automatic pressure relief mechanism, through the cooperation of its fixed cavity, air outlet cavity, purification cavity, adsorption plate, piston, movable plate, telescopic spring, threaded groove, threaded rod, rotating wheel, limiting groove, and limiting block, can automatically relieve pressure in the heating cavity. Simultaneously, it can adsorb and purify the gas inside the heating cavity, ensuring that the gas discharged into the air is less likely to cause air pollution or affect the health of workers. It can also drive the piston to move and exhaust gas from the heating cavity, thus greatly improving the practicality of the device. Furthermore, by setting a power mechanism above the heating cavity, the power mechanism, through the cooperation of its mounting cavity, servo motor, driving gear, and driven gear, can drive the placement plate to rotate slowly, thereby rotating the catalyst on the placement plate. This results in more uniform heating of the catalyst, leading to better catalyst regeneration and significantly improving the working efficiency of the device. Attached Figure Description

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a pentafluoroethane catalyst regeneration device, including a heating chamber 1, a door 2 hinged to the front end of the heating chamber 1, heating wires 3 installed on both sides inside the heating chamber 1, multiple placement plates 4 installed inside the heating chamber 1, the multiple placement plates 4 being connected by connecting rods 5, a power mechanism provided at the top of the heating chamber 1, and an automatic pressure relief mechanism provided on one side of the heating chamber 1.

[0019] The automatic pressure relief mechanism includes a fixed cavity 10, an exhaust cavity 11, a purification cavity 12, an adsorption plate 13, a piston 14, a movable plate 15, a telescopic spring 16, and a transmission structure. The fixed cavity 10 is installed on one side of the heating cavity 1, and the exhaust cavity 11 is installed at the top of the fixed cavity 10. The purification cavity 12 is installed on one side of the top of the heating cavity 1, and the adsorption plate 13 is detachably installed inside the purification cavity 12. One end of the exhaust cavity 11 is connected to one side of the purification cavity 12 through a pipe. The movable plate 15 is installed inside the fixed cavity 10. A telescopic spring 16 is installed on one side of the movable plate 15, and a piston 14 is installed on one end of the telescopic spring 16. The transmission structure includes a threaded groove 17, a threaded rod 18, a rotating wheel 19, and a limiting structure. The threaded groove 17 is formed at both ends on one side of the fixed cavity 10. The threaded rod 18 is inserted through the threaded groove 17. One end of the threaded rod 18 is rotatably connected to one side of the movable plate 15, and the rotating wheel 19 is installed on the other side of the threaded rod 18. When the air pressure inside the heating cavity 1 is too high, the air pressure pushes the piston 14 to move. At this time, the telescopic spring... Spring 16 contracts, causing piston 14 to move. Air pressure enters the fixed cavity 10 and then flows from the outlet cavity 11 into the purification cavity 12. After being adsorbed and purified by the adsorption plate 13, the air is finally discharged from the top rear end of the purification cavity 12. When exhaust is needed from the heating cavity 1, rotating wheel 19 drives threaded rod 18 to rotate. Because of the threaded connection between threaded groove 17 and threaded rod 18, threaded rod 18 moves within threaded groove 17. Under the limitation of limiting groove 20 and limiting block 21, threaded rod 18 drives movable plate 15 to move... The movement of the piston 14 causes the gas inside the heating chamber 1 to enter the purification chamber 12 from the exhaust chamber 11. After being adsorbed and purified by the adsorption plate 13, the gas is discharged. This allows for automatic pressure relief of the heating chamber 1 and also purifies the gas inside the heating chamber 1, preventing air pollution and minimizing the impact on workers' health. Furthermore, the movement of the piston 14 facilitates exhaust from the heating chamber 1, greatly improving the practicality of the device during use.

[0020] The limiting structure includes a limiting groove 20 and a limiting block 21. The limiting groove 20 is located at the bottom inside the fixed cavity 10. The limiting block 21 is provided inside the limiting groove 20. The top end of the limiting block 21 is connected to the bottom end of the movable plate 15. The cross-section of the limiting groove 20 is larger than the cross-section of the limiting block 21. The limiting groove 20 and the limiting block 21 form a sliding structure. In use, the mutual cooperation between the limiting groove 20 and the limiting block 21 can limit the movement of the movable plate 15, making the movable plate 15 more stable when moving.

[0021] The power mechanism includes a mounting cavity 6, a servo motor 7, a drive gear 8, and a driven gear 9. The mounting cavity 6 is installed at the top of the heating cavity 1. The servo motor 7 is installed at the top of the mounting cavity 6. The drive gear 8 is installed on one side inside the mounting cavity 6. The output end of the servo motor 7 is connected to one end of the drive gear 8. The driven gear 9 meshes with one side of the drive gear 8. The bottom end of the driven gear 9 is connected to the top of the connecting rod 5. The cross-section of the drive gear 8 is smaller than that of the driven gear 9. The drive gear 8 drives the driven gear 9 to perform a deceleration motion. In use, the servo motor 7 is started to drive the drive gear 8 to rotate, which in turn drives the driven gear 9 to rotate. This, in turn, drives the placement plate 4 to rotate via the connecting rod 5, thereby uniformly heating the catalyst and improving the catalyst regeneration effect, thus greatly improving the working efficiency of the device during use.

[0022] Working principle: The operator opens door 2, places the catalyst on top of placement plate 4, and then closes door 2. At this time, heating wire 3 is activated to heat the interior of heating chamber 1, thereby calcining the catalyst at high temperature. Servo motor 7 is activated, driving drive gear 8 to rotate, which in turn drives driven gear 9 to rotate. This, in turn, uses connecting rod 5 to rotate placement plate 4, ensuring uniform heating of the catalyst. When the internal pressure of heating chamber 1 becomes too high, the pressure pushes piston 14 to move. At this time, extension spring 16 contracts, causing piston 14 to move, and the pressure enters the fixed chamber 10 and flows into the clean air chamber 11. Inside the purification chamber 12, the gas is adsorbed and purified by the adsorption plate 13, and finally discharged from the top of the rear end of the purification chamber 12. When it is necessary to exhaust the heating chamber 1, the rotating wheel 19 drives the threaded rod 18 to rotate. Since the threaded groove 17 and the threaded rod 18 are threadedly connected, the threaded rod 18 moves inside the threaded groove 17. Under the limitation of the limiting groove 20 and the limiting block 21, the threaded rod 18 drives the movable plate 15 to move, which in turn drives the piston 14 to move, so that the gas inside the heating chamber 1 enters the purification chamber 12 from the exhaust chamber 11, is adsorbed and purified by the adsorption plate 13, and then discharged.
