Description

Technical Field

[0001] This utility model relates to the technical field of propylene preparation apparatus, specifically a temperature control device for propylene preparation based on propane dehydrogenation. Background Technology

[0002] The temperature control device maintains the reaction within the required temperature range by precisely regulating the heat input to the propane dehydrogenation reactor. The device typically includes a heating element, a temperature sensor, and a computer control system. The heating element provides the heat required for the reaction, while the temperature sensor monitors the reaction temperature in real time and feeds the data back to the computer control system.

[0003] Existing temperature control devices have the following shortcomings: the process of propane dehydrogenation to propylene is a strongly endothermic reaction, which usually needs to be carried out at a temperature exceeding 600°C to obtain a high conversion rate. However, traditional temperature control devices have a single heating element with a small contact area with the reactants, resulting in insufficient heating effect. Moreover, high-temperature conditions can easily cause impurities to adhere to the surface of the heat pipe of the heating element, making cleaning inconvenient. In order to address the shortcomings of the existing technology, this utility model provides a temperature control device for the preparation of propylene from propane dehydrogenation to solve the above problems.

[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 temperature control device for preparing propylene using propane dehydrogenation, according to the attached... Figure 1-4 As shown, it includes an upper cover 2 set on the reactor body 1 and a support seat 3 fixedly connected to the upper cover 2.

The heater bases 5 are movably latched in the latching seat 4. The heater bases 5 are provided with heating tubes 51 and temperature sensors 52. External cables 53 are connected to the heating tubes 51 and temperature sensors 52. The external cables 53 are connected to an external control computer, and remote temperature control and monitoring are realized through the computer.

[0026] The support 3 is equipped with a fixing unit 7 for quickly fixing the assembly frame 6.

[0027] This temperature control device for propylene production from propane dehydrogenation employs a main frame 6 to simultaneously fix the positions of multiple heater bases 5. During the propane dehydrogenation process, the multiple evenly arranged heater bases 5 provide rapid heating to the reactants, ensuring uniform heating and good temperature control. Furthermore, the design of the fixing unit 7 and the support base 3 facilitates the assembly and disassembly of the main frame 6 and the multiple heater bases 5. This makes the surfaces of the heater bases 5, heating tubes 51, and temperature sensors 52 easy to clean and maintain, reducing impurity adhesion, extending lifespan, and improving the temperature control stability of the device during multiple processing cycles.

[0028] The fixing unit 7 includes a station plate 71 mounted on the support base 3 and a guide rod 72 fixedly connected to the station plate 71.

The screw rod 76 is rotatably connected to the adjustment platform 73. The fixing unit 7 has a compact structural design. The screw rod 76 is designed to facilitate the position adjustment of the adjustment platform 73 and the fixing rod 74, thereby facilitating the insertion of the fixing rod 74 into the limit hole 61, and thus fixing the assembly frame 6 and the multiple sets of heater bases 5.

[0029] When it is necessary to install the main assembly frame 6 and the heater base 5, firstly, snap the main assembly frame 6 onto the support seat 3, and at the same time snap multiple sets of heater bases 5 into the inside of the snap-fit ​​seat 4, so that multiple sets of heating tubes 51 and temperature sensors 52 are located in the installation position inside the reactor body 1. At this time, rotate the lead screw 76, so that the lead screw 76 pushes the adjustment table 73 and the fixing rod 74 to move as a whole. The fixing rod 74 is finally inserted into the limiting hole 61, realizing the quick installation of the main assembly frame 6 and the heater base 5. The subsequent disassembly method is the reverse operation, which is convenient.

[0030] The lead screw 76 is equipped with a rotating handle 77. The design of the rotating handle 77 makes it easy to rotate the lead screw 76, thereby making the operation of the fixing unit 7 convenient.

[0031] The support base 3 is provided with a limiting strip 31 for limiting and reinforcing the assembly frame 6. Through the design of the limiting strip 31, the assembly frame 6 is conveniently positioned when it is snapped onto the support base 3, and the force is stable after snapping.
