[0002] Photocatalysis is a process in which light energy is converted into chemical energy and promoted by exciting reactant molecules or exciting the catalyst to form a complex with reactant molecules under light irradiation, thus promoting the reaction. Traditional photocatalytic reactors, such as the one disclosed in CN117282472B (announcement number for a catalytic cracking catalyst aging method and equipment), employ an external light source penetrating a transparent furnace body. However, the low structural strength of the transparent furnace body limits the large-scale production capacity of the equipment. To address this, an internal light source has been developed, allowing the furnace body to be made of higher-strength steel. However, an internal light source presents the problem of air leakage between the light-transmitting tube and the furnace body. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a light source sealing structure for a photocatalytic reactor, comprising a furnace body and a light-transmitting tube located in the reaction chamber of the furnace body;

[0005] The furnace body is provided with an assembly hole that connects to its own reaction chamber. The assembly hole includes a threaded area and a first sealing area, and a sealing ring is provided on the first sealing area.

[0006] The light-transmitting tube includes an opening, which is threadedly connected to the threaded area, and the tube wall of the opening is pressed against the sealing ring.

[0007] Furthermore, the light source sealing structure of the aforementioned photocatalytic reactor also includes an end cap covering the opening. The end cap is provided with a first sealing ring, and a second sealing area is provided at the end of the assembly hole away from the reaction chamber of the furnace body. The second sealing area and the light-transmitting tube form a sealing space. The first sealing ring is inserted into the sealing space. The first sealing ring is pressed against the side wall of the assembly hole and the tube wall of the light-transmitting tube, respectively. The end cap is provided with a wiring hole.

[0008] Furthermore, the end of the first sealing ring furthest from the end cap has a chamfer.

[0009] Furthermore, the end cap is provided with a second sealing ring that is inserted into the opening and abuts against the inner wall of the light-transmitting tube.

[0010] Furthermore, the end of the second sealing ring furthest from the end cap has a chamfer.

[0011] Furthermore, the assembly hole is arranged sequentially from the outside of the furnace body to the reaction chamber of the furnace body, including the second sealing area, the threaded area, and the first sealing area.

[0012] Furthermore, the assembly hole is arranged sequentially from the outside of the furnace body to the reaction chamber of the furnace body, including the second sealing area, the first sealing area, and the threaded area.

[0013] Furthermore, the assembly hole is arranged sequentially from the outside of the furnace body to the reaction chamber of the furnace body, including the second sealing area, the first sealing area, the threaded area, and the first sealing area.

[0014] Furthermore, the tube wall of the opening is wrapped with sealing tape.

[0015] Furthermore, a gas detector is provided on the outer wall of the furnace body near the assembly hole.

[0016] The beneficial effects of this utility model are as follows: An assembly hole is provided on the furnace body for threaded connection with the light-transmitting tube.

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figure 1 and Figure 2As shown, the present invention discloses a light source sealing structure for a photocatalytic reactor, comprising a furnace body 1 and a light-transmitting tube 2 located in the reaction chamber of the furnace body 1; the furnace body 1 is provided with an assembly hole 11 communicating with its own reaction chamber, the assembly hole 11 including a threaded area and a first sealing area, the first sealing area being provided with a sealing ring 12; the light-transmitting tube 2 includes an opening 21, the opening 21 being threadedly connected to the threaded area, the tube wall of the opening 21 being pressed against the sealing ring 12.

[0025] Working principle: An assembly hole 11 is provided on the furnace body 1 for threaded connection with the light-transmitting tube 2. The light-transmitting tube 2 is connected to the furnace body 1 by thread, which can provide a certain degree of sealing. At the same time, a sealing ring 12 is provided in the assembly hole 11, and the deformation of the sealing ring 12 further seals the gap between the light-transmitting tube 2 and the furnace body 1. This prevents gas from leaking from the furnace body 1 through the assembly hole 11 and prevents gas from entering the light-transmitting tube 2 and corroding the lamp plate.

[0026] It is worth noting that an annular groove is provided on the first sealing area for installing the sealing ring 12, and the light-transmitting tube 2 is preferably made of quartz glass.

[0027] In some implementations, please refer to Figure 2 As shown, the light source sealing structure of a photocatalytic reactor further includes an end cap 3 covering the opening 21. The end cap 3 is provided with a first sealing ring 31. The end of the assembly hole 11 away from the reaction chamber of the furnace body 1 is provided with a second sealing area. The second sealing area and the light-transmitting tube 2 form a sealed space. The first sealing ring 31 is inserted into the sealed space and is pressed against the side wall of the assembly hole 11 and the tube wall of the light-transmitting tube 2. The end cap 3 is provided with a wiring hole 32. By covering the opening 21 with the end cap 3, the lamp plate used for light emission inside the light-transmitting tube 2 is protected, and the wires on the lamp plate can extend through the wiring hole 32. By inserting the first sealing ring 31 into the sealed space between the second sealing area and the light-transmitting tube 2, the gap between the light-transmitting tube 2 and the furnace body 1 can be further sealed.

[0028] It is worth noting that the end of the first sealing ring 31 away from the end cap 3 has a chamfer. The chamfer facilitates the insertion of the first sealing ring 31 into the sealing space.

[0029] In some implementations, please refer to Figure 2 As shown, the end cap 3 is provided with a second sealing ring 33 which is inserted into the opening 21 and abuts against the inner wall of the light-transmitting tube 2. The second sealing ring 33 seals the gap between the end cap 3 and the light-transmitting tube 2.

[0030] It is worth noting that the end of the second sealing ring 33 away from the end cap 3 has a chamfer. The chamfer facilitates the insertion of the second sealing ring 33 into the opening 21.

[0031] In the first embodiment of the assembly hole 11 arrangement, the assembly hole 11 is arranged sequentially from the outside of the furnace body 1 to the reaction chamber of the furnace body 1, including the second sealing area, the threaded area, and the first sealing area.

[0032] In the second embodiment of the assembly hole 11 arrangement, the assembly hole 11 is arranged sequentially from the outside of the furnace body 1 to the reaction chamber of the furnace body 1, including the second sealing area, the first sealing area, and the threaded area.

[0033] In the third embodiment of the assembly hole 11 arrangement, the assembly hole 11 is arranged sequentially from the outside of the furnace body 1 to the reaction chamber of the furnace body 1, including the second sealing area, the first sealing area, the threaded area, and the first sealing area.

[0034] In some embodiments, sealing tape (not shown) is wrapped around the wall of the opening 21. Before the opening 21 is threaded into the threaded area of ​​the mounting hole 11, sealing tape is wrapped around the wall of the opening 21 to further seal the gap between the light-transmitting tube 2 and the furnace body 1.

[0035] In some embodiments, a gas detector (not shown in the figure) is provided on the outer wall of the furnace body 1 near the assembly hole 11. The gas detector is used to detect the gas at the assembly hole 11 to determine whether there is a gas leak at the assembly hole 11.
