[0024] The two embodiments of the application will be described in detail below in conjunction with the drawings.

[0025] First embodiment:

[0026] Figures 1-5 The electrolytic photocatalytic device is shown, which includes reaction equipment 4, the inner end of the reaction equipment 4 is provided with a reaction tube 7, the inner end of the reaction tube 7 is fixedly connected with a pad block 6 at the lower side, the upper end of the pad block 6 is placed with a quartz electrolytic cell 5, the inner end of the reaction tube 7 is provided with a graphite anode 9 and a nickel-based alloy cathode 8, both the graphite anode 9 and the nickel-based alloy cathode 8 extend into the quartz electrolytic cell 5, the upper end of the reaction tube 7 is provided with a sealing flange 12, the inner end of the reaction tube 7 is provided with a heat preservation tube plug 11, the upper end of the reaction tube 7 is provided with an inlet valve 13 at the middle, the upper end of the reaction tube 7 is provided with an outlet valve 15 at the right side, the upper end of the reaction tube 7 is provided with a sealing electrode 14, the left and right ends of the reaction equipment 4 are symmetrically fixedly connected with viewing mirrors 19, the left side of the reaction equipment 4 is provided with a solar simulator 3, and the inner end of the reaction equipment 4 is provided with a heating furnace 17.

[0027] Figures 1-5 The heating furnace 17 is shown located outside the reaction tube 7, the right end of the reaction equipment 4 is provided with a high-speed camera 2, and the lower end of the reaction equipment 4 is provided with a temperature control touch screen 1.

[0028] Figures 1-5The reaction device 4 in the present scheme can support both heating furnace 17 and solar simulator 3 operation modes at the same time, which is suitable for electrolysis and photo-thermal catalytic reaction of molten salt substances under high temperature conditions, and can compare the performance differences of electrolysis products under two heating modes. Specifically, the heating furnace 17 is arranged around the quartz electrolytic cell 5 in the reaction tube 7, and the material in the quartz electrolytic cell 5 is heated to a preset temperature by resistance heating, which can reach 700°C at the highest. During the heating process, the temperature control system monitors the temperature in the quartz electrolytic cell 5 in real time through the temperature measuring thermocouple 10, and adjusts the power of the heating furnace 17 through the temperature control touch screen 1 to ensure that the temperature is stable within the target range, so that the material is molten at high temperature to form a conductive molten salt system, providing the necessary conditions for electrolysis reaction. At the same time, the solar simulator 3 is arranged on the side of the quartz electrolytic cell 5, which can simulate the solar radiation to heat the material in the quartz electrolytic cell 5. The photo-thermal radiation can penetrate the surface of the material to achieve uniform heating, while significantly reducing energy consumption, in line with the green environmental protection concept. The temperature control touch screen 1 is also used to monitor and adjust the power of photo-thermal heating to ensure that the material is molten and reaches the required temperature range of the experiment. By comparing the electrolysis reaction effects under the electric heating mode and the photo-thermal heating mode, the influence of the two heating modes on the performance of the electrolysis products can be analyzed, which provides experimental basis for the application of photo-thermal catalytic technology in the electrolysis field. The gas products generated during the electrolysis process are discharged through the gas outlet valve 15 and enter the gas collection and analysis system for component detection. After the electrolysis is completed, by comparing the gas product composition, electrolysis product structure and performance indicators such as catalytic activity and conductivity under the electric heating mode and the photo-thermal heating mode, the optimization effect of photo-thermal heating on the electrolysis process can be analyzed in depth. In addition, the observation mirrors 19 are symmetrically fixed and connected to the left and right ends of the reaction device 4, which are used to observe the material state and reaction phenomenon in real time during the electrolysis process. The high-speed camera 2 is arranged at the right end of the reaction device 4, which can capture the dynamic changes during the electrolysis process and provide visual data support for experimental analysis. The gas inlet valve 13 and the gas outlet valve 15 are used to control the input and output of the reaction gas respectively to ensure the stability and controllability of the electrolysis process. By integrating the electric heating and photo-thermal heating modes, combined with the stirring mechanism and intelligent temperature control system, efficient electrolysis and photo-thermal catalytic reaction of molten salt substances are realized.
