Description

Technical Field

[0001] The invention relates to the technical field of reaction devices, and in particular to a photocatalytic norbornadiene isomerization reaction device. Background Art

[0002] Tetracycloheptane is an important high-energy aerospace fuel, which can be used in aerospace propulsion systems such as rockets, missiles, satellites and spacecraft. Compared with kerosene fuel, it has the advantage of high energy, and compared with hydrazine fuel, it has the advantage of high safety. Tetracycloheptane is generally synthesized by photochemical methods, using norbornadiene as raw material, ultraviolet light irradiation, and solid photocatalyst as a catalyst for the reaction, and tetracycloheptane is generated through the intramolecular addition reaction of norbornadiene.

[0003] The current photocatalytic norbornadiene isomerization reaction device is found to have at least the following technical problems:

[0004] First, there is no effective preliminary mixing method for the mixing process of norbornadiene and the photocatalyst, which makes it difficult to quickly and fully mix the two during subsequent stirring. The active sites of the photocatalyst cannot fully contact with the norbornadiene molecules in time, resulting in slow reaction startup and low efficiency.

[0005] Second, in the process of adding materials into the reactor, materials are prone to agglomeration, and the existing equipment does not have corresponding measures to break them up, resulting in uneven distribution of materials and uneven reaction.

[0006] Third, during the photocatalytic reaction, the transparent plates around the UV lamp lack an effective cleaning device, and the reactants are easily coked and adhered to the surface of the surrounding transparent plates, which hinders the transmission of UV light and affects the normal progress of the photocatalytic reaction.

[0007] Fourth, in the glass reactor in the prior art, the stirring blades are generally arranged at the bottom of the reactor, and the stirring during the reaction of the upper and lower layers is not comprehensive and uniform, resulting in that the reaction materials at each layer cannot fully contact and react, thereby reducing the reaction efficiency.

[0016] (III) Beneficial effects

[0017] 1. The present invention connects a mixing tank and a threaded conveying blade to a stirring shaft through a first pulley, a second pulley and a belt body, so that the device can discharge raw materials while stirring the internal reaction raw materials. When the stirring blade is rotating and the raw materials are discharged, newly added norbornadiene and photocatalyst can be immediately mixed with the existing reaction mixture after entering the reaction device, thereby helping to maintain the uniformity of the concentration of reactants and catalysts in the reaction system, so that the reaction can be carried out stably under ideal conditions.

The rotating rod arranged in the middle can play a role in breaking up the materials. When the materials contact the rotating rod, the agglomerates are subjected to collision and friction and will be dispersed into smaller particles or individuals, so that the materials can be more evenly distributed at the bottom of the reactor.

A threaded conveying blade 33 is rotatably installed, a rotating rod 13 is fixedly installed on the threaded conveying blade 33, a first pulley 12 is fixedly installed at the lower end of the rotating rod 13, and a belt body 11 is set between the first pulley 12 and the second pulley 14. When using the device to perform an isomerization reaction on norbornadiene, it is necessary to first select a photocatalyst, then purify norbornadiene, remove impurities that may affect the reaction, so as to ensure the purity and efficiency of the reaction, select a container suitable for the photocatalytic reaction, and then use an analytical balance to accurately weigh a certain amount of norbornadiene and the photocatalyst, and it is necessary to ensure that the photocatalyst The catalyst and norbornadiene are in a suitable ratio to achieve the best reaction effect. The weighed norbornadiene and photocatalyst are respectively added to the norbornadiene storage tank and the photocatalyst storage tank in the storage box 21. The present invention arranges the storage box 21 on the transparent reactor 51, so that the device can place the norbornadiene and the photocatalyst in the norbornadiene storage tank and the photocatalyst storage tank in the storage box 21 in advance, and can conveniently and accurately measure and add the photocatalyst and norbornadiene. This arrangement also allows step-by-step addition to control the reaction process.

[0034] A stirring power assembly 55 is provided at the upper end of the top cover 54, and the lower end of the stirring power assembly 55 is fixedly installed with the stirring shaft 15 through an output shaft. A stirring blade 18 is sleeved on the circumferential surface of the stirring shaft 15, and the stirring shaft 15 is rotatably installed on the first glass jar 41 and the second glass jar 42 through a sealed bearing. A bracket 44 is fixedly installed on the stirring shaft 15, and a wiping rod 45 is fixedly installed on the bracket 44. After being placed in the norbornadiene storage tank and the photocatalyst storage tank, the user can pull up the two lifting rods 27 according to the requirements of the ratio between norbornadiene and the photocatalyst. Before pulling up, the stirring power assembly 55 needs to be opened so that the stirring power assembly 55 drives the stirring through the output shaft. The mixing shaft 15 rotates, and then the upward pulling of the two lifting rods 27 will separate the two switch plates 26 from the discharge port 25 opened in the storage box 21. At this time, the norbornadiene and photocatalyst in the norbornadiene storage tank and the photocatalyst storage tank will fall in equal proportion, and will first fall into the mixing tank 31. At this time, since the stirring shaft 15 is rotating, the stirring shaft 15 drives the second pulley 14 to rotate, and the second pulley 14 and the first pulley 12 are driven by the belt body 11 and also rotate. The first pulley 12 will drive the rotating rod 13 to rotate, and the rotating rod 13 will drive the threaded conveying blade 33 in the mixing tank 31 to rotate. When the thread When the conveying blade 33 rotates, the norbornadiene and the photocatalyst can be preliminarily mixed. After the preliminarily mixing in the mixing tank 31 by the threaded conveying blade 33, the photocatalyst can be dispersed in the norbornadiene to prepare for the subsequent sufficient stirring. The present invention provides a mixing tank 31 and a threaded conveying blade 33 inside the mixing tank 31, so that the device can preliminarily mix the norbornadiene and the photocatalyst. The preliminarily mixing can give the norbornadiene molecules more contact opportunities with the active sites of the photocatalyst. The photocatalyst usually has specific active centers, which produce active species that can trigger reactions under light excitation. The preliminarily mixing allows the norbornadiene to The molecules can reach the active sites of the photocatalyst more quickly, thereby accelerating the start of the reaction and improving the reaction efficiency. The present invention connects the mixing tank 31 and the threaded conveying blade 33 through the first pulley 12, the second pulley 14 and the belt body 11 to the stirring shaft 15, so that the device can discharge the raw materials while stirring the internal reaction raw materials. When the stirring blade 18 rotates and discharges the raw materials, the newly added norbornadiene and photocatalyst can be immediately mixed with the existing reaction mixture after entering the reaction device, which helps to maintain the uniformity of the concentration of reactants and catalysts in the reaction system and enable the reaction to proceed stably under ideal conditions.

[0035] Two connecting rods 47 are fixedly installed on the second glass jar 42, and the two connecting rods 47 are fixedly installed at the lower end of the top cover 54. The left side of the storage box 21 is a storage tank for norbornadiene, and the right side of the storage box 21 is a storage tank for photocatalysts. Two switch plates 26 are respectively located on both sides of the partition 22. The upper ends of the two switch plates 26 are fixedly installed with lifting rods 27. After preliminary mixing, norbornadiene and photocatalysts will fall along the connecting flange 32 toward the inside of the transparent reactor 51, and in the process of falling, they will reciprocate with the rotating rod 13. During the falling process, norbornadiene and the photocatalyst will agglomerate due to factors such as static electricity and adsorption between particles. The rotating rod 13 arranged in the middle can play a role in breaking up the materials. When the materials contact the rotating rod 13, the agglomerates are subjected to collision and friction and will be dispersed into smaller particles or individuals, so that the materials can be more evenly distributed at the bottom of the reactor, which is conducive to a more uniform reaction in the entire bottom area of ​​the reactor. After the norbornadiene and the photocatalyst to be reacted completely enter the transparent reactor 51, the stirring blades 18 located on the stirring shaft 15 can stir the norbornadiene and the photocatalyst well to ensure that the norbornadiene and the photocatalyst are fully mixed. The ultraviolet lamps 43 in the first glass jar 41 and the second glass jar 42 are turned on (the ultraviolet lamps 43 are wirelessly designed and are also provided with a wireless control function). At this time, the five ultraviolet lamps 43 will emit ultraviolet light to the norbornadiene and photocatalyst mixture in the transparent reactor 51, so that the ultraviolet light can react with the photocatalyst. Moreover, while the stirring shaft 15 is rotating, the stirring blades 18 can stir the norbornadiene and the photocatalyst well to ensure that the norbornadiene and the photocatalyst are fully mixed. The mixing shaft 15 will drive the bracket 44 to rotate, and the bracket 44 will drive the wiping rod 45 to rotate. A wiping cotton is provided between the wiping rod 45 and the first glass jar 41 and the second glass jar 42, so the wiping rod 45 can clean the surface of the first glass jar 41 and the second glass jar 42 to ensure the stability of the illumination of the ultraviolet lamp 43 inside the first glass jar 41 and the second glass jar 42, and avoid the reactants from polymerizing under light induction during the isomerization reaction to form coke and adhere to the outer surface of the ultraviolet lamp tube, thereby hindering the transmission of ultraviolet light.

[0036] The connecting flange 32 is fixedly installed on the top cover 54, and the mixing tank 31, the connecting flange 32 and the storage box 21 are connected. A rotating groove 17 is opened in the chassis 16, and the belt body 11, the first pulley 12 and the second pulley 14 are rotatably installed in the rotating groove 17 opened in the chassis 16. When the bracket 44 and the wiping rod 45 rotate, the extended leaf 46 at the side end of the wiping rod 45 will also rotate synchronously, so that the norbornadiene and photocatalyst at all levels in the transparent reactor 51 can be stirred, which helps to improve the reaction efficiency.

[0037] Working principle:

[0038] In the first step, when using the device to carry out an isomerization reaction of norbornadiene, it is necessary to first select a photocatalyst, then purify the norbornadiene to remove impurities that may affect the reaction to ensure the purity and efficiency of the reaction, select a container suitable for the photocatalytic reaction, and then use an analytical balance to accurately weigh a certain amount of norbornadiene and photocatalyst. It is necessary to ensure that the photocatalyst and norbornadiene are in a suitable ratio to achieve the best reaction effect. The weighed norbornadiene and photocatalyst are respectively added to the norbornadiene storage tank and the photocatalyst storage tank in the storage box 21. The present invention uses a storage box 21 set on the transparent reactor 51, so that the device can place the norbornadiene and the photocatalyst in the norbornadiene storage tank and the photocatalyst storage tank in the storage box 21 in advance, and can conveniently and accurately measure and add the photocatalyst and norbornadiene. This setting also allows step-by-step addition to control the reaction process.

[0039] In the second step, after placing them in the norbornadiene storage tank and the photocatalyst storage tank, the user can pull up the two lifting rods 27 according to the ratio requirements between norbornadiene and the photocatalyst. Before pulling up, the stirring power component 55 needs to be opened so that the stirring power component 55 drives the stirring shaft 15 to rotate through the output shaft. Then, the pulling up of the two lifting rods 27 will separate the two switch plates 26 from the discharge port 25 opened in the storage box 21. At this time, the norbornadiene and photocatalyst in the norbornadiene storage tank and the photocatalyst storage tank will fall in equal proportions, and will first fall on In the mixing tank 31, at this time, since the stirring shaft 15 is rotating, the stirring shaft 15 drives the second pulley 14 to rotate, and the second pulley 14 and the first pulley 12 are driven by the belt body 11 to rotate as well, and the first pulley 12 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the threaded conveying blade 33 in the mixing tank 31 to rotate. When the threaded conveying blade 33 rotates, the norbornadiene and the photocatalyst can be preliminarily mixed. After the preliminarily mixing in the mixing tank 31 by the threaded conveying blade 33, the photocatalyst can be helped. The catalyst is dispersed in norbornadiene to prepare for subsequent sufficient stirring. The present invention provides a mixing tank 31 and a threaded conveying blade 33 inside the mixing tank 31, so that the device can perform preliminary mixing on norbornadiene and the photocatalyst. The preliminary mixing can give the norbornadiene molecules more contact opportunities with the active sites of the photocatalyst. The photocatalyst usually has specific active centers, which produce active species that can trigger reactions under light excitation. The preliminary mixing allows the norbornadiene molecules to reach the active sites of the photocatalyst more quickly, thereby accelerating the start of the reaction and improving the photocatalytic efficiency. High reaction efficiency. The present invention connects the mixing tank 31 and the threaded conveying blade 33 with the stirring shaft 15 through the first pulley 12, the second pulley 14 and the belt body 11, so that the device can discharge the raw materials while stirring the internal reaction raw materials. When the stirring blade 18 rotates and discharges the raw materials, the newly added norbornadiene and photocatalyst can be immediately mixed with the existing reaction mixture after entering the reaction device, which helps to maintain the uniformity of the reactant and catalyst concentrations in the reaction system and enables the reaction to proceed stably under ideal conditions.

[0040] In the third step, after the preliminary mixing, the bornadiene and the photocatalyst will fall along the connecting flange 32 toward the inside of the transparent reactor 51, and overlap with the rotating rod 13 during the falling process. During the falling process, the bornadiene and the photocatalyst will agglomerate due to factors such as electrostatic effects and adsorption between particles. The rotating rod 13 arranged in the middle can play a role in breaking up the materials. When the materials contact the rotating rod 13, the agglomerates are subjected to collision and friction and will be dispersed into smaller particles or individuals, so that the materials can be more evenly distributed at the bottom of the reactor, which is conducive to a more uniform reaction in the entire bottom area of ​​the reactor. After the bornadiene and the photocatalyst that need to react completely enter the transparent reactor 51, the stirring blades 18 located on the stirring shaft 15 can stir the bornadiene and the photocatalyst well to ensure that the bornadiene and the photocatalyst are fully mixed.

[0041] The fourth step is to turn on the ultraviolet lamps 43 inside the first glass jar 41 and the second glass jar 42 (the ultraviolet lamps 43 are wirelessly designed and have a wireless control function). At this time, the five ultraviolet lamps 43 will emit ultraviolet light to the mixture of norbornadiene and photocatalyst inside the transparent reactor 51, so that the ultraviolet light can react with the photocatalyst. Moreover, while the stirring shaft 15 rotates, the stirring shaft 15 will drive the bracket 44 to rotate, and the bracket 44 will drive the wiping rod 45 to rotate. A wiping cotton is provided between the wiping rod 45 and the first glass jar 41 and the second glass jar 42, so the wiping rod 45 can clean the surface of the first glass jar 41 and the second glass jar 42 to ensure the stability of the illumination of the ultraviolet lamps 43 inside the first glass jar 41 and the second glass jar 42, and avoid the polymerization of the reactants under light induction during the isomerization reaction to form coke and adhere to the outer surface of the ultraviolet lamp tube, thereby hindering the transmission of ultraviolet light.

[0042] In the fifth step, while the support 44 and the wiping rod 45 are rotating, the extended leaf 46 at the side end of the wiping rod 45 will also rotate synchronously, so that the norbornadiene and the photocatalyst at each layer in the transparent reactor 51 can be stirred, thereby helping to improve the reaction efficiency. The reaction between norbornadiene and the photocatalyst has the following stages:

[0043] Adsorption stage: Norbornadiene molecules first adsorb on the surface of the photocatalyst;

[0044] Excitation stage: Under light conditions, the photocatalyst absorbs photons to generate electron pairs. These photogenerated carriers can migrate to the catalyst surface and interact with the adsorbed norbornadiene molecules.

[0045] Reaction stage: electrons react with adsorbed norbornadiene molecules, initiating isomerization of the double bond;

[0046] Desorption stage: The generated isomerization products are desorbed from the surface of the photocatalyst, allowing the catalyst surface to be regenerated and able to continue to participate in the next round of reaction.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
