[0026] Please refer to the attached Figures 1-3, A catalyst screening reactor, including a reactor cavity 1. The reactor cavity 1 has two covers on its top. The two covers are respectively a first reactor top cover 11 and a second reactor top cover 10. The second reactor top cover 10 is located at the center of the first reactor top cover 11. Inside the reactor cavity 1, there is a heating support platform 3. The heating support platform 3 can fix the position of the sample, ensure stability during the heating process, and at the same time provide a uniform heat distribution. On the heating support platform 3, there is a heat - equalizing platform 4. The heat - equalizing platform 4 can effectively reduce the temperature gradient and ensure temperature uniformity in the working area. At the center of the top of the heat - equalizing platform 4, there is a sample platform 6. On the heat - equalizing platform 4, there is a gas distributor 5. The gas distributor 5 is located around the sample platform 6. On the first reactor top cover 11, there is a handle 14. The handle 14 is provided with anti - slip strips. The handle 14 facilitates the staff to open the first reactor top cover 11.
[0027] Specifically, the gas distributor 5 can evenly distribute the gas in the device, avoid the gas concentration being too high or too low in local areas, ensure sufficient contact of the reactants, and thus improve the operation efficiency and effect of the device.
[0028] On the outer wall of the reactor cavity 1, there are multiple socket - weld terminals 2. The multiple socket - weld terminals 2 are symmetrically arranged. The setting of the socket - weld terminals 2 makes the installation process rapid and convenient, provides good structural strength, and effectively prevents fluid leakage. One end of the socket - weld terminal 2 is for gas inlet, and the other ends of the symmetrically arranged socket - weld terminals 2 are for gas outlet.
[0029] On the outer wall of the reactor cavity 1, there is also a first electrode flange 8. The other end of the first electrode flange 8 is provided with a second electrode flange 9. The setting of the first electrode flange 8 and the second electrode flange 9 ensures the sealing between the electrode and the reaction vessel and prevents the leakage of the reaction medium.
[0030] At the center of the second reactor top cover 10, there is a window pane 12. Between the second reactor top cover 10 and the first reactor top cover 11, there are multiple O - ring seals 13. Inside the reactor cavity 1, there is an annular seal. The first reactor top cover 11 is hermetically set on the reactor cavity 1 through the seal. The seal can effectively prevent the leakage of liquid or gas in the reactor and ensure the sealing of the reactor. The setting of the window pane 12 facilitates the external infrared thermal imaging camera to observe the inside of the reactor cavity 1.
[0031] A plurality of mutually adapted threaded ports 7 are provided on both the top cover 11 of the first reactor and the reactor cavity 1. Bolts are threadedly connected in the plurality of threaded ports 7. The length dimensions of the threaded ports provided on the top cover 11 of the first reactor and the reactor cavity 1 are the same, and the shapes of the top cover 11 of the first reactor and the reactor cavity 1 are mutually adapted. During use, the top cover 11 of the first reactor equipped with the window pane 12 is fixed to the reactor cavity 1 by bolts. When it is necessary to remove the top cover 11 of the first reactor, the bolts can be unscrewed with a torque wrench.
[0032] The working principle of the present utility model is as follows:
[0033] During use, first weigh the sample to be screened, slowly pour and load the sample onto the sample stage 6 through weighing paper, then fix the sample stage 6 on the uniform heating stage 4, fix the top cover 11 of the first reactor equipped with the window pane 12 on the reactor cavity 1 by bolts, introduce gas into the reactor cavity 1 through the socket weld terminal 2 to increase the pressure, and then use external equipment to heat the heating support stage 3 and the uniform heating stage 4. An infrared thermal imaging camera (not shown in the figure) is provided corresponding to directly above the window pane 12. The infrared thermal imaging camera observes the inside of the reactor cavity 1 through the window pane 12. After the reaction, cool down and then discharge the gas. Finally, open the top cover 11 of the first reactor with a torque wrench and take out the sample stage 6 for cleaning.
[0034] Finally, it should be noted that components such as the uniform heating stage involved in the present utility model are all general standard components or components known to those skilled in the art. Their structures and principles can all be known to those skilled in the art through technical manuals or obtained through conventional experimental methods.
