Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical reactors, and specifically to an experimental-grade photocatalytic reactor. Background Technology
[0002] Photocatalytic reactors have become a key tool in green chemistry due to their high efficiency and environmental friendliness, especially in the pharmaceutical and energy fields, but cost and scale-up issues remain bottlenecks for industrialization.
[0003] Before industrial-scale production of photocatalytic reactions, extensive laboratory experiments are required. Using production-grade equipment directly for optimization experiments would lead to material waste due to the large size of the equipment and the significant safety risks posed by the large number of reactants under immature experimental conditions. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model proposes an experimental-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; one end of the heat exchange shell is provided with a lamp tube insertion assembly for inserting the lamp tube into the heat exchange shell, and the other end is provided with a material inlet and outlet assembly for inputting and outputting the reaction fluid into the light-transmitting reaction tube.
[0005] Specifically, the lamp insertion assembly includes a first flange for use with a first heat exchange housing flange of the heat exchange housing, and the first flange has a lamp fixing bracket for fixing the lamp on the side away from the heat exchange housing.
[0006] Specifically, the material inlet / outlet assembly includes a second flange for use with a second heat exchange shell flange of the heat exchange shell. The second flange is provided with an inlet end clamping connector for inputting reaction fluid into the light-transmitting reaction tube and an outlet end clamping connector for outputting the reaction fluid in the light-transmitting reaction tube.
[0007] After the lamp is inserted into the reactor, it will be exposed to the heat exchange fluid inside the heat exchange shell, which is very unsafe. This problem can be solved if the lamp can be separated from the heat exchange fluid. In order to solve this technical problem, this application provides a specific implementation scheme in which a light-transmitting tube is also provided inside the heat exchange shell to separate the lamp from the heat exchange fluid inside the heat exchange shell.
[0008] Furthermore, the first and second heat exchanger housing flanges are respectively provided with first fixing flanges for fixing the light-transmitting tube, which are used in conjunction with second fixing flanges at both ends of the light-transmitting tube. In use, the light-transmitting tube is fixed between the first and second heat exchanger housing flanges by connecting the first and second fixing flanges. This isolates the lamp tube from the heat exchange fluid when it is inserted into the heat exchanger housing. After insertion, the lamp tube can be fixed to the first flange using a lamp tube holder.
[0009] As an experimental-grade photocatalytic reactor, only one light-transmitting reaction tube is needed. To increase the length of the light-transmitting reaction tube, it can be arranged in a spiral pattern around its outer periphery. This increases the length of the light-transmitting reaction tube while ensuring sufficient illumination of the reaction fluid inside. Furthermore, to meet the requirements of light transmission and installation, the light-transmitting reaction tube can be made of polytetrafluoroethylene (PFA).
[0010] The heat exchange fluid inside the heat exchange shell is flowing, so the light-transmitting reaction tube needs to be stably fixed inside the heat exchange shell. Therefore, this application provides a specific embodiment in which a reaction tube fixing bracket for fixing the light-transmitting reaction tube is provided on the outside of the light-transmitting tube.
[0011] This invention relates to an experimental-grade photocatalytic reactor that uses a polytetrafluoroethylene (PFA) light-transmitting reaction tube. Single-channel experimental-grade reaction tubes of varying lengths can be configured to meet specific needs. Rapid installation is achieved through a clamp connection at both ends of the light-transmitting reaction tube. The photocatalytic reactor utilizes a light-transmitting tube to isolate the lamp from the heat exchange fluid, thus achieving both photocatalysis and production safety. Attached Figure Description

Detailed Implementation
[0013] 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.
[0014] Example 1 like Figure 1 and 2 As shown, this utility model provides an experimental-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; one end of the heat exchange shell 3 is provided with a lamp tube insertion assembly 4 for inserting the lamp tube 2 into the heat exchange shell 3, and the other end is provided with a material inlet and outlet assembly 5 for inputting and outputting the reaction fluid into the light-transmitting reaction tube 1.
[0015] Specifically, the lamp insertion assembly 4 includes a first flange 4-1 for use with the first heat exchange housing flange 3-1 of the heat exchange housing 3. The first flange 4-1 has a lamp fixing bracket 4-2 for fixing the lamp 2 on the side away from the heat exchange housing 3.
[0016] Specifically, the material inlet / outlet assembly 5 includes a second flange 5-1 for use with the second heat exchange shell flange 3-2 of the heat exchange shell 3. The second flange 5-1 is provided with an inlet end clamping connector 5-2 for inputting reaction fluid into the light-transmitting reaction tube 1 and an outlet end clamping connector 5-3 for outputting the reaction fluid in the light-transmitting reaction tube 1.
[0017] 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 1 , Figure 2 and Figure 3 As shown, the heat exchange housing 3 is also provided with a light-transmitting tube 6 for separating the lamp tube 2 from the heat exchange fluid inside the heat exchange housing 3.
[0018] Furthermore, such as Figure 3 and Figure 5As shown, the first heat exchanger housing flange 3-1 and the second heat exchanger housing flange 3-2 are respectively provided with a first fixing flange 7 for fixing the light-transmitting tube 6. The first fixing flange 7 is used in conjunction with the second fixing flanges 6-1 at both ends of the light-transmitting tube 6. In use, the light-transmitting tube 6 is fixed between the first heat exchanger housing flange 3-1 and the second heat exchanger housing flange 3-2 by connecting the first fixing flange 7 and the second fixing flange 6-1. In this way, when the lamp tube 2 is inserted into the heat exchanger housing 3, the lamp tube 2 can be isolated from the heat exchange fluid. After the lamp tube 2 is inserted into the heat exchanger housing 3, it can be fixed to the first flange 4-1 by the lamp tube fixing bracket 4-2.
[0019] As an experimental-grade photocatalytic reactor, only one light-transmitting reaction tube 1 is needed. To increase the length of the light-transmitting reaction tube 1, it can be spirally arranged around the outer periphery of the light-transmitting tube 6. 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 illumination. Furthermore, to meet the requirements of light transmission and installation, the material of the light-transmitting reaction tube 1 can be polytetrafluoroethylene (PFA).
[0020] 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 holder 8 for fixing the light-transmitting reaction tube 1 is provided on the outside of the light-transmitting tube 6.
[0021] Specifically, such as Figure 4 As shown, the reaction tube holder 8 includes a holder body 8-1, a slot 8-2 for fixing the light-transmitting reaction tube 1 disposed on the holder body 8-1, and a fixing part 8-3 for fixing the reaction tube holder 8 to the light-transmitting tube 6. Further, the reaction tube holder 8 is fixed to the light-transmitting tube 6 by a fastener 9. As a specific embodiment, such as... Figure 5 As shown, the fixing member 9 includes fixing discs 9-1 respectively disposed at both ends of the light-transmitting tube 6, and a plurality of fixing rods 9-2 disposed between the two fixing discs 9-1; the fixing rods 9-2 are provided with fixing buckles 9-3 for use in conjunction with the fixing part 8-3. Specifically, the fixing buckles 9-3 are nuts, and during fixing, the nuts are used to cooperate with the fixing discs 9-1 to clamp the fixing part 8-3.
[0022] In this invention, both the light-transmitting reaction tube 1 and the light-transmitting tube 6 are made of light-transmitting materials.
[0023] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0024] 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.
