Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-pressure reactor technology, and in particular relates to a high-pressure reactor. Background Technology
[0002] A high-pressure reactor is a pressure vessel capable of carrying out chemical reactions under high pressure. Depending on their application, high-pressure reactors are divided into large-volume industrial reactors and small-volume reactors used for pilot-scale experiments, such as small reactors with a volume of several hundred milliliters.
[0003] The main structure of a current pressure vessel consists of a vessel body and a vessel cover mounted on the vessel body. The vessel cover houses various structures for monitoring the reaction and the feed material, including those for feeding, gas intake, temperature measurement, and pressure measurement. Therefore, due to the large number and complexity of pipes and components on the vessel cover, the vessel body can only be installed using traditional methods, specifically bolts. During installation, the mounting holes on the vessel cover are aligned with the screws on the vessel body for assembly.
[0004] The specific reason is that the complex piping, temperature measurement, and pressure measurement components are intricately arranged on the vessel lid, making it impossible to secure the lid to the vessel body using a simple installation method. Rotary installation, such as threaded connection installation, not only offers faster installation speed but also leverages the high stability and anti-loosening properties of the threaded structure to achieve quick assembly of the high-pressure vessel.
[0005] With the development of technology, automated workbenches have been gradually adopted in industry. In automated reaction processes, the disassembly and installation of the vessel lid and body are often achieved by using robotic arms to clamp and tighten the lid or body. Therefore, automated reaction scenarios place high demands on the ease of installation and the simplicity of the overall vessel structure. Specifically, during the robotic arm's clamping of the vessel body and lid in automated reactions, the robotic arm often needs to grasp the lid or body and assemble it. However, traditional high-pressure reactors have overly complex and disorganized pipes and control components on the lid, causing interference from these components when the clamping arm is holding the lid. This prevents the clamping arm from accurately gripping the lid and installing it onto the vessel body. Furthermore, moving the lid is extremely difficult (the assembly of the vessel body and lid often requires moving them to the assembly area, such as the assembly area).
[0006] Therefore, designing a simple and easy-to-clamp vessel structure is crucial for achieving automated operation. Utility Model Content
[0007] Based on the above background, the purpose of this utility model is to provide a high-pressure reactor.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A high-pressure reactor includes a reactor body and a reactor cover threaded onto the reactor body, and also includes an inlet and outlet gas pipeline structure integrated on the reactor cover;
[0010] The inlet and outlet gas pipeline structure includes inlet and outlet gas pipes, one end of which is connected to the vessel body, and the other end of which is equipped with a first three-way valve. One end of the first three-way valve is connected to a pressure transmitter, and the other end of the first three-way valve is connected to an external inlet and outlet gas pipeline.
[0011] It also includes a temperature control and pressure relief structure for controlling the temperature inside the vessel, the temperature control and pressure relief structure including a pressure relief pipe fixedly installed on the vessel lid, the outlet end of the pressure relief pipe being connected to a second three-way valve;
[0012] The outlet of the second three-way valve is connected to a pressure relief valve;
[0013] The temperature control and pressure relief structure also includes a thermocouple, the detection end of which passes through the pressure relief pipe and is located inside the vessel.
[0014] The thermocouple is spaced apart from the pressure relief pipe and the second three-way valve to form a pressure relief channel.
[0015] Preferably, the top of the vessel body is integrally formed with a threaded connector, and the outer wall of the threaded connector and the inner wall of the vessel lid have mutually cooperating threaded structures.
[0016] Preferably, the second three-way valve and the pressure relief valve are connected by a pressure relief connecting pipe.
[0017] Preferably, the pressure relief valve is equipped with a pressure relief pipe at its pressure relief end.
[0018] Preferably, the first three-way valve is connected to the pressure transmitter via a connecting pipe.
[0019] Preferably, a pressure transmitter connector is installed on the top of the pressure transmitter;
[0020] The pressure transmitter connector is electrically connected to a pressure signal data line.
[0021] Preferably, the thermocouple is electrically connected to a temperature signal data line.
[0022] This utility model has the following beneficial effects:
[0023] 1. By integrating the pressure relief, temperature measurement, and high-pressure gas discharge functions into the vessel lid and combining them with the aforementioned inlet and outlet gas pipeline structure, the vessel structure is simplified. The advantages of this simplified vessel structure are:
[0024] During the assembly of the reactor vessel by gripping the lid and body with a robotic arm, the complex pipe and component structure on the lid is greatly simplified after optimization, allowing the robotic arm to grasp the lid more accurately, thus facilitating the assembly of the lid and body.
[0025] 2. The structure of the vessel lid has been optimized to enable easier movement of the lid after it is gripped by the robotic arm.

[0026] 3. The optimized structural design further enhances the ease of use of the autoclave.
[0027] 4. The use of threaded installation for the vessel lid and body provides a foundation for the realization of an automated experimental platform. Specifically, the automated experimental platform operates entirely through robotic arms, and the threaded connection of the vessel body and lid provides the conditions for the robotic arm to clamp the vessel body and tighten it onto the lid. Compared with traditional bolt and other connection methods, the assembly method of the vessel lid and body is simpler and the difficulty of automated operation is lower. Attached Figure Description

[0036] Example 1
[0037] like Figure 1-3 As shown, a high-pressure reactor includes a high-pressure reactor 5, which includes a reactor body 52 and a reactor cover 51 threadedly connected to the reactor body 52. Specifically, the threaded connection is as follows: a threaded connector 521 is integrally formed on the top of the reactor body 52, and the outer side wall of the threaded connector 521 and the inner side wall of the reactor cover 51 have mutually cooperating threaded structures.
[0038] The lid 51 and the body 52 are fixedly connected by a threaded connection in a simple way. During the connection process, it is only necessary to screw the body 52 onto the lid 51.
[0039] The installation method of the vessel lid 51 and vessel body 52 provides a foundation for realizing an automated experimental work platform. Specifically, the automated experimental platform operates entirely through robotic arms, and the threaded connection of the vessel body 52 and vessel lid 51 provides the conditions for the robotic arm to clamp the vessel body 52 and screw it onto the vessel lid 51.
[0040] Example 2
[0041] like Figure 1-3 As shown, this embodiment simplifies the structure of the vessel body 52 based on the structure of embodiment 1. Specifically, it simplifies the gas path structure and control element structure on the vessel cover 51. By simplifying the structure of the vessel cover 51, it provides convenience for the robotic arm to clamp the vessel cover 51 and the vessel body 52. In traditional high-pressure vessels, the independent installation of pipeline elements and control elements on the vessel cover 51 results in an overly complex structure. This complex structure seriously interferes with the robotic arm's ability to clamp the vessel cover 51 and attach it to the vessel body 52.
[0042] Specifically, the vessel lid 51 is equipped with an integrated inlet and outlet gas pipeline structure; the inlet and outlet gas pipeline structure is used for subsequent high-pressure reactor reactions, such as high-pressure hydrogenation reactions, to introduce reaction hydrogen into the vessel through the inlet and outlet gas pipeline structure.
[0043] Specifically, the inlet and outlet gas pipeline structure includes inlet and outlet gas pipes 1, the lower end of which is connected to the vessel body 52 (the lower end of the inlet and outlet gas pipes 1 is fixedly installed on the vessel cover 51), and a first three-way valve 61 is installed at the upper end of the inlet and outlet gas pipes 1. This is achieved through two ports of the first three-way valve 61. One port is connected to a pressure transmitter 3 (the first three-way valve 61 and the pressure transmitter 3 are connected through a connecting pipe 32), and the other port of the first three-way valve 61 is installed on an external inlet and outlet gas pipeline 11.
[0044] During operation, in the existing manner, the external inlet and outlet gas pipes 11 are connected to an external gas source, so that the hydrogen gas used for the reaction is introduced into the reactor body 52 through the first three-way valve 61 and the inlet and outlet gas pipes 1.
[0045] Similar to the existing pressure transmitter 3, the pressure transmitter 3 is used to monitor the pressure inside the vessel body 52. It is installed in the same way as the existing pressure transmitter 3, with a pressure transmitter connector 7 mounted on its top. As in the existing method, the pressure transmitter connector 7 is electrically connected to a pressure signal data line 31 (used to transmit pressure signals). Also as in the existing method, the pressure signal data line 31 is electrically connected to a backend for feedback of the pressure signal inside the vessel body 52.
[0046] The pressure transmitter 3, which provides feedback on the pressure signal inside the vessel body 52, is integrated into the inlet and outlet gas pipes 1 through the aforementioned three-way valve structure design. This method, in conjunction with the temperature control and pressure relief structure described below, significantly simplifies the piping and component structure on the vessel cover 51 through integrated installation.
[0047] Example 3
[0048] like Figure 1-3 As shown, based on the structure of Embodiment 2, this embodiment further simplifies the structure of the lid 51 by adopting an integrated installation method. The present invention makes the following improvements:
[0049] A temperature control and pressure relief structure for controlling the temperature inside the vessel body 52 is installed on the vessel lid 51. The temperature control and pressure relief structure includes a pressure relief pipe 2 fixedly installed on the vessel lid 51. The outlet end of the pressure relief pipe 2 is connected to a second three-way valve 62. At the same time, the outlet end of the second three-way valve 62 is connected to a pressure relief valve 4 (the connection method is: the second three-way valve 62 and the pressure relief valve 4 are connected through a pressure relief connecting pipe 42).
[0050] Meanwhile, the temperature control and pressure relief structure also includes a thermocouple (not shown in the figure), the detection end of which passes through the pressure relief pipe 2 and is located inside the vessel body 52.
[0051] Specifically, the thermocouple passes through the upper and lower interfaces of the second three-way valve 62, then through the pressure relief pipe 2 and into the vessel body 52 (that is, the detection end of the thermocouple passes through the pressure relief pipe 2 and is located inside the vessel body 52).
[0052] In the existing configuration, a sealing joint is used to seal the upper interface of the thermocouple and the second three-way valve 62, and a sealing nut is used to seal the lower interface of the second three-way valve 62 and the pressure relief pipe 2. Therefore, after the thermocouple passes through the second three-way valve 62 and the pressure relief pipe 2, the second three-way valve 62 and the pressure relief pipe 2 remain sealed.
[0053] Since the pressure relief pipe 2 is used for pressure relief, if the pressure inside the vessel is too high, in order to ensure that the vessel 52 operates under normal pressure, it is necessary to relieve the pressure in the vessel 52, such as by releasing the high-pressure gas inside the vessel 52. Therefore, in order to maintain smooth airflow, a pressure relief channel is formed between the thermocouple and the pressure relief pipe 2 at intervals. Similarly, a channel is also formed between the thermocouple and the valve chamber of the second three-way valve 62 through which it passes (i.e., the thermocouple and the valve chamber of the second three-way valve 62 are set at intervals).
[0054] When pressure is released, the high-pressure gas passes through a pressure relief channel formed by the thermocouple and the pressure relief pipe 2, reaching the valve chamber of the second three-way valve 62. From the channel, it exits through the side port of the second three-way valve 62 and enters the pressure relief valve 4. It then exits from the pressure relief valve 4's discharge end. Therefore, the pressure relief valve 4's discharge end is connected to a pressure relief pipe 41. Thus, the high-pressure gas exits from the pressure relief pipe 41.
[0055] The thermocouples mentioned above are conventional thermocouples used in high-pressure reactors to monitor the temperature of materials inside the reactor. They have the same structure as existing thermocouples. Temperature signal data line 21 is electrically connected to the thermocouple (i.e., temperature signal data line 21 passes through the sealed joint on the interface of the second three-way valve 62 and is sealed with the sealed joint).
[0056] The above structure integrates pressure relief, temperature measurement, and high-pressure gas discharge into the vessel lid 51, along with the aforementioned inlet and outlet gas pipes, thus simplifying the vessel body 52 structure. The advantages of this simplified vessel body 52 structure are:
[0057] 1. During the assembly of the reactor vessel by gripping the lid 51 and the body 52, the complex pipe and component structure on the lid 51 is greatly simplified after optimization. Therefore, the robotic arm can grasp the lid 51 more accurately, which facilitates the assembly of the lid 51 and the body 52.
[0058] 2. The structure of the vessel lid 51 has been optimized to make it easier to move the vessel lid 51 after the robotic arm grips it. The integrated installation of the pipeline structure and control components facilitates the gripping and moving of the vessel lid 51 and avoids interference with its movement.
[0059] 3. The optimized structural design further enhances the ease of use of the autoclave.
[0060] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
