[0002] Propane dehydrogenation reaction needs to be carried out under high temperature and low pressure conditions. However, excessively high temperature will cause the C-C bond to break more easily than the CH bond, triggering side reactions such as deep cracking and deep dehydrogenation. At the same time, it will accelerate coking on the catalyst surface, leading to catalyst deactivation. Therefore, it is necessary to strictly control the reaction temperature.

[0003] Reactors for the production of propylene from propane dehydrogenation typically have various sensors installed on top. Because the reaction for propylene production from propane dehydrogenation has high requirements for sensors such as temperature, and the reaction conditions are more demanding, the frequency of sensor inspection, maintenance, and replacement / upgrading is higher. Traditionally, the sensors in these reactors are usually screwed directly onto the top cover in multiple locations. This fixing method makes overall sensor upgrades inconvenient, and the top cover is difficult to disassemble and reassemble, resulting in limited operating space and inconvenient maintenance. To address the shortcomings of existing technologies, this invention provides a reactor for the production of propylene from propane dehydrogenation to solve the aforementioned problems.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a reactor for the preparation of propylene based on propane dehydrogenation, which solves the problem that in traditional reactors, the sensor part is usually directly screwed onto the top cover in multiple positions. This fixing method makes it inconvenient to upgrade the overall sensor, and the top cover is difficult to disassemble and install, with little operating space, thus making maintenance inconvenient.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a reactor for the preparation of propylene using propane dehydrogenation, according to the appendix. Figure 1-4 As shown, it includes a reactor tank 1 and a reactor sealing cover 2 disposed on the reactor tank 1;

[0025] The reactor tank 1 is provided with a first fixing ring 11, and the reactor sealing cover 2 is provided with a second fixing ring 21. The first fixing ring 11 and the second fixing ring 21 are fixed by bolts. The fixing method of the first fixing ring 11 and the second fixing ring 21 makes it easy to disassemble and assemble the reactor tank 1 and the reactor sealing cover 2.

[0026] The reactor sealing cover 2 is equipped with a quick docking seat 3, and the sensor positioning seat 4 is movablely connected inside the quick docking seat 3. Multiple sensor bodies 44 are provided on the sensor positioning seat 4.

[0027] The quick docking seat 3 has a clamping unit 5 on its side for limiting the sensor positioning seat 4. The clamping unit 5 includes a sleeve 51 set on the quick docking seat 3 and a screw 52 threadedly connected to the sleeve 51. A wedge block 53 is rotatably connected to the screw 52, ​​and the wedge block 53 is engaged with the sensor positioning seat 4.

[0028] This reactor for propylene production based on propane dehydrogenation concentrates multiple sensor bodies 44 on sensor positioning seats 4. Utilizing the snap-fit ​​positioning method between the sensor positioning seats 4 and quick-connect seats 3, the sensor positioning seats 4 and multiple quick-connect seats 3 can be quickly and easily installed and positioned on the reactor sealing cover 2. During the propylene production process based on propane dehydrogenation, this ensures that each sensor body 44 on the reactor sealing cover 2 can be quickly replaced and upgraded, facilitating maintenance, ensuring a stable reaction process, and meeting usage requirements.

[0029] The device, through the design of the clamping unit 5, makes it easy to lock the sensor positioning seat 4 on the quick docking seat 3. The sensor positioning seat 4 is provided with a locking groove 41 corresponding to the position of the wedge block 53.

[0030] When the sensor positioning seat 4 needs to be installed, first align the sensor positioning seat 4 with the inside of the quick docking seat 3 and snap it in place. After it is fully engaged, rotate the lead screw 52 so that the lead screw 52 drives the wedge block 53 to move. The lead screw 52 is equipped with a rotating handle 55, which makes the rotation of the lead screw 52 easy and effortless. After the wedge block 53 moves, the wedge block 53 engages with the inside of the locking groove 41. The inclined surface pressure of the wedge block 53 is applied to the sensor positioning seat 4, so that the sensor positioning seat 4 and the quick docking seat 3 are sealed internally, resulting in good stability.

[0031] The wedge block 53 has sliders 54 on both sides and a groove 511 on the sleeve 51. The sliders 54 are slidably connected in the groove 511. When the wedge block 53 moves, it drives the sliders 54 to slide along the groove 511. The sliders 54 provide lateral support to the wedge block 53 to ensure the stability of the wedge block 53 under force.

[0032] A sealing ring 43 is movably engaged between the sensor positioning seat 4 and the quick docking seat 3. The design of the sealing ring 43 ensures good sealing between the sensor positioning seat 4 and the quick docking seat 3.

[0033] The sensor positioning base 4 is equipped with a maintenance plate 42. The design of the maintenance plate 42 makes it easy to open the internal space of the sensor positioning base 4, thereby facilitating the inspection and maintenance of each sensor body 44.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
