Technical Field

Research on microchannels themselves and their application in scientific research and applied experiments have also been carried out. However, the current problem is that when conducting heat transfer-related research on microchannel reactors, the reactor itself will lose heat to the outside, resulting in inaccurate experimental data. Utility Model Content
[0003] In view of the problems in the background art, the present invention provides a reaction system suitable for vacuum insulation, including a reactor and a pump body. The reactor is set in a box, and the box body is provided with a vacuum extraction port. The pump body is connected to the vacuum extraction port to realize the vacuuming of the box body.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please refer to Figures 1-2 This utility model provides a reaction system suitable for vacuum insulation, and the preferred embodiment is as follows:
[0028] Example 1: A vacuum-insulated reaction system includes a reactor 1 and a pump 2. The reactor 1 is housed within a housing 3. The housing 3 has a vacuum extraction port 4. The pump 2 is connected to the vacuum extraction port 4 to evacuate the housing 3. One side of the housing 3 has a lid 5 that can be opened and closed. One side of the lid 5 is hinged to the housing 3 via a hinge. The other side of the lid 5 has a handle 7. The side of the handle 7 on the housing 3 is opposite to the side of the hinge 6. The lid 5 can be opened or closed using the handle 7. To achieve a seal, a sealing strip is provided at the contact point between the lid 5 and the housing 3, enhancing the sealing performance of the housing 3 when the lid 5 is closed. To facilitate observation of the internal reactor 1, the other side of the housing 3 and the lid 5 can be made of transparent material. The system is equipped with a material inlet 11, a material outlet 12, a heat exchange medium inlet 13, and a heat exchange medium outlet 14, all connected to reactor 1 via pipelines. Temperature sensors are installed at each of these locations to detect the temperature during the experiment, facilitating experimental research. A purge valve 8 and a back pressure valve 9 are located on the other side of the chamber 3. The purge valve 8 is used to clean the channels of reactor 1, while the back pressure valve 9 regulates the pressure required during the reaction. Both the back pressure valve 9 and the purge valve 8 are located on the outside of the chamber 3, a design that is more convenient to use than placing them inside. The reaction system also includes a display screen 10, which is located on the top of the outside of the chamber 3, on the same side as the back pressure valve 9 and the purge valve 8.
[0029] Example 2: The difference from Example 1 is that one side of the cover 5 is hinged to the box body 3 by a bearing and a pin, and the other side of the box body 3 is made of transparent material, with a back pressure valve 9 located below the transparent material.
[0030] Example 3: The difference from Example 2 is that a purge valve 8 is provided under the transparent material on the other side of the box.
[0031] Example 4: The difference from Example 1 is that the material used for the box body 3 is heat insulation material.
[0032] Example 5: The difference from Example 1 is that the reactor 1 is set on the side wall inside the box 3, and the connection between the reactor 1 and the box 3 is made of aerogel felt, which reduces the heat transfer from the reactor 1 to the side wall of the box 3 and thus reduces the impact on the experimental results.
[0033] Operating Procedure: Close the lid 5, then connect the pump body 2 to the vacuum port 4 to create a vacuum inside the chamber 3. Once a vacuum is formed, the material and heat exchange medium enter the reactor 2 through the material inlet 11 and heat exchange medium inlet 13 respectively, and are then discharged through the material outlet 12 and heat exchange medium outlet 14 respectively, thus completing the experiment. During this process, the reactor 2 is in a vacuum state, and heat cannot be transferred through the medium, thus creating an adiabatic environment, reducing the impact on experimental data, and ensuring the accuracy of research results.
[0034] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
