Technical Field

[0001] This utility model relates to the technical field of chemical reactors, and specifically to an industrial-grade photocatalytic reactor. Background Technology

[0002] Photocatalytic reactors, with their high efficiency and environmental friendliness, have become a key tool in green chemistry, showing significant potential, especially in the pharmaceutical and energy sectors. However, cost and scale-up remain bottlenecks for industrialization. Currently, the main drawbacks of commonly available photocatalytic reactors are as follows: 1. Single light source and low light source utilization; 2. Short residence time and low reaction yield; 3. Defective flow field design exacerbates mass transfer unevenness, further reducing efficiency; 4. High equipment investment and operating costs. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model proposes an industrial-grade photocatalytic reactor, comprising a light-transmitting reaction tube for fluid reaction, a lamp tube for providing a light source for the fluid in the light-transmitting reaction tube, and a heat exchange shell for providing temperature control for the fluid reacting in the light-transmitting reaction tube. The two ends of the heat exchange shell are respectively provided with a feed end assembly for inputting the reaction fluid into the light-transmitting reaction tube and a discharge end assembly for outputting the reacted fluid in the light-transmitting reaction tube.

[0004] Based on the above scheme, the feed end assembly includes a flow divider plate and a flow divider box; the flow divider plate is provided with a feed end clamp connector for connecting the light-transmitting reaction tubes; the flow divider box is provided with a feed inlet on the side away from the flow divider plate, and a flow divider groove is formed between the flow divider plate and the flow divider box for distributing the reaction fluid input from the feed inlet to different light-transmitting reaction tubes.

[0005] The discharge end assembly includes a manifold plate and a manifold box; the manifold plate is provided with a discharge end clamp connector for connecting the light-transmitting reaction tubes; the manifold box is provided with a discharge port on the side away from the manifold plate, and a manifold groove is provided on the side closer to the manifold plate for collecting and transporting the fluids after reaction in different light-transmitting reaction tubes to the discharge port.

[0006] This invention relates to an industrial-grade photocatalytic reactor that uses polytetrafluoroethylene (PFA) transparent reaction tubes. Different lengths of reaction channels can be configured according to actual needs, and rapid installation is achieved through clamp connections at both ends of the transparent reaction tubes. The feed and discharge end components at both ends of the reactor, via diversion and collection channels, enable free distribution and collection of the reaction fluid.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Example 1

[0016] like Figure 1 As shown, this utility model provides an industrial-grade photocatalytic reactor, including a light-transmitting reaction tube 1 for fluid reaction, a lamp tube 2 for providing a light source for the fluid in the light-transmitting reaction tube 1, and a heat exchange shell 3 for providing temperature control for the fluid reacting in the light-transmitting reaction tube 1.

[0017] The number of light-transmitting reaction tubes 1 is greater than or equal to 2, and the two ends of the heat exchange shell 3 are respectively provided with a feed end assembly 8 for inputting reaction fluid into the light-transmitting reaction tube 1 and a discharge end assembly 9 for outputting the reaction fluid in the light-transmitting reaction tube 1.

[0018] like Figure 5As shown in the figure, in a specific implementation, the feed end assembly 8 includes a flow divider plate 8-1 and a flow divider box 8-2; the flow divider plate 8-1 is provided with a feed end clamp connector 8-4 for connecting the light-transmitting reaction tube 1; the flow divider box 8-2 is provided with a feed inlet 8-3 on the side away from the flow divider plate 8-1, and a flow divider groove 8-5 is formed between the flow divider plate 8-1 and the flow divider box 8-2 for distributing the reaction fluid input from the feed inlet 8-3 to different light-transmitting reaction tubes 1.

[0019] Specifically, the diversion channel 8-5 can be as follows: Figure 5 and Figure 6 The groove connecting the feed inlet 8-3 formed on the side of the diverter box 8-2 near the diverter plate 8-1 shown in the figure; or the groove connecting the feed end clamping connector 8-4 formed on the side of the diverter plate 8-1 near the diverter box 8-2, which is not shown in the figure; or shallow grooves formed on the side where the diverter plate 8-1 and the diverter box 8-2 are connected, and after the diverter plate 8-1 and the diverter box 8-2 are assembled, the two shallow grooves form the diverter groove 8-5. Figure 6 In the middle, a circular hole at the center of the diversion channel 8-5 is connected to the feed inlet 8-3 on the diversion tube box 8-2. The positions of the six dashed holes around this circular hole correspond to the projection positions of the feed end clamping connector 8-4 on the diversion tube plate 8-1 on the diversion tube box 8-2.

[0020] In use, the inlet end of the light-transmitting reaction tube 1 is connected to the feed end clamp connector 8-4, and the reaction fluid is input through the feed port 8-3. The reaction fluid first enters the diversion tank 8-5, and then is input through the diversion tank 8-5 into different light-transmitting reaction tubes 1 connected to different feed end clamp connectors 8-4 for photocatalytic reaction.

[0021] like Figure 5 As shown, the discharge end assembly 9 includes a manifold plate 9-1 and a manifold box 9-2; the manifold plate 9-1 is provided with a discharge end clamp connector 9-4 for connecting the light-transmitting reaction tube 1; the manifold box 9-2 is provided with a discharge port 9-3 on the side away from the manifold plate 9-1, and a manifold groove 9-5 is provided on the side close to the manifold plate 9-1 for collecting and transporting the fluids after reaction in different light-transmitting reaction tubes 1 to the discharge port 9-3.

[0022] Like the diversion channel 8-5, the manifold channel 9-5 can be a channel formed on the manifold sheet 9-1 and / or the manifold box 9-2.

[0023] In use, connect the outlet end of the light-transmitting reaction tube 1 to the discharge end clamping connector 9-4. The reacted fluid enters the manifold 9-5 from different light-transmitting reaction tubes 1, and then the fluid is collected and transported to the discharge port 9-3 through the manifold 9-5.

[0024] During assembly, the two sides of the distribution tube sheet 8-1 are respectively connected to the flange at one end of the heat exchange shell 3 and the distribution tube box 8-2; the two sides of the manifold tube sheet 9-1 are respectively connected to the flange at the other end of the heat exchange shell 3 and the manifold box 9-2. The flanges of the heat exchange shell 3 are not labeled in the figure.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, in a specific embodiment, the manifold plate 9-1 and the manifold box 9-2 are provided with through holes 9-6 for inserting the lamp tube 2 into the reactor. Specifically, as shown... Figure 7 As shown, the through hole 9-6 is located on the central axis of the manifold plate 9-1 and the manifold box 9-2; the manifold groove 9-5 is formed on the outer periphery of the through hole 9-6.

[0026] After the lamp tube 2 is inserted into the reactor, it will be exposed to the heat exchange fluid inside the heat exchange shell 3, which is very unsafe. This problem can be solved by isolating the lamp tube 2 from the heat exchange fluid. To address this technical problem, this application provides a specific implementation scheme, such as... Figure 2 and 3 As shown, the heat exchange housing 3 is further provided with a light-transmitting tube 4 for accommodating the lamp tube 2 (i.e., the heat exchange housing 3 is further provided with a light-transmitting tube 4 for separating the lamp tube 2 from the heat exchange fluid inside the heat exchange housing 3). Further, as... Figure 3 and Figure 5 As shown, the diverter plate 8-1 and the manifold plate 9-1 are respectively provided with light-transmitting tube support frames 7 for fixing the light-transmitting tube 4. A first sealing flange 7-1 is provided at the end of each light-transmitting tube support frame 7; a second sealing flange 4-1 is provided at the end of each light-transmitting tube 4 for use with the first sealing flange 7-1. During fixing, the light-transmitting tube 4 is fixed between the two light-transmitting tube support frames 7 through the cooperation of the first sealing flange 7-1 and the second sealing flange 4-1.

[0027] In this way, by inserting the lamp tube 2 through the through hole 9-6 into the interior of the heat exchange housing 3, the lamp tube 2 can be isolated from the heat exchange fluid. After the lamp tube 2 is inserted into the interior of the heat exchange housing 3, it can be fixed to the manifold box 9-2 by the lamp tube fixing bracket 2-1.

[0028] The light-transmitting reaction tube 1, connected between the feed end clamping connector 8-4 and the discharge end clamping connector 9-4, is spirally arranged around the outer periphery of the fixed light-transmitting tube 4. This increases the length of the light-transmitting reaction tube 1 and ensures that the reaction fluid inside the light-transmitting reaction tube 1 receives sufficient light. Furthermore, to meet the requirements of light transmission and installation, the material of the light-transmitting reaction tube 1 can be polytetrafluoroethylene (PFA).

[0029] The heat exchange fluid inside the heat exchange shell 3 is flowing, so the light-transmitting reaction tube 1 needs to be stably fixed inside the heat exchange shell 3. Therefore, this application provides a specific implementation scheme, such as... Figures 1-3 As shown, a reaction tube fixing bracket 5 for fixing the light-transmitting reaction tube 1 is provided on the outside of the light-transmitting tube 4.

[0030] Specifically, such as Figure 4 As shown, the reaction tube holder 5 includes a holder body 5-1, a slot 5-2 on the holder body 5-1 for fixing the light-transmitting reaction tube 1, and a fixing part 5-3 for fixing the reaction tube holder 5 to the light-transmitting tube 4. Further, the reaction tube holder 5 is fixed to the light-transmitting tube 4 by a fixing member 6. In a specific embodiment, the fixing member 6 includes fixing discs 6-1 respectively disposed at both ends of the light-transmitting tube 4, and a plurality of fixing rods 6-2 disposed between the two fixing discs 6-1; each fixing rod 6-2 is provided with a fixing buckle 6-3 for use in conjunction with the fixing part 5-3. Specifically, the fixing buckle 6-3 is a nut; during fixing, two nuts or a nut and a fixing disc 6-1 are used to clamp the fixing part 5-3.

[0031] In this invention, both the light-transmitting reaction tube 1 and the light-transmitting tube 4 are made of light-transmitting materials.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
