Description

Technical Field

[0001] This invention relates to the field of organic chemistry, and more specifically to a metal-organic chemical photoreaction device. Background Technology

[0002] Organic photochemical reactions refer to a class of chemical reactions in which organic molecules are excited to a high-energy state after absorbing visible or ultraviolet light, thereby initiating processes such as the breaking, formation, or rearrangement of chemical bonds. Their reaction pathways and products often differ from those of thermal reactions, enabling some transformations that are difficult to occur under conventional heating conditions. They have important applications in fields such as organic synthesis, materials preparation, and photocatalysis.

[0003] Chinese patent CN213222116U discloses a metal-organic chemical photoreaction device. This device provides a fixing structure. In use, the metal-organic chemical photoreaction device body is placed between clamps, and the knob is rotated to make the bolts push the clamps until the metal-organic chemical photoreaction device body is fixed. It can effectively fix metal-organic chemical photoreaction device bodies of different sizes and can play a shock absorption and protection role for the metal-organic chemical photoreaction device body.

[0004] In the operation of existing photoreactors, the light intensity distribution inside the reaction liquid is uneven due to the single layout of the light source and the fixed direction of illumination. The photon flux in some areas is low, which significantly reduces the overall reaction rate. At the same time, the distance between the light source and the reaction liquid is usually fixed and cannot be dynamically adjusted according to the reaction requirements. Due to the limited optical path, the photons have a limited penetration path in the solution and are often absorbed or scattered before they can fully participate in the excitation reaction, resulting in low photon utilization.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) The present invention utilizes the coordinated operation of a fixed frame, an adjustment drive assembly, an adjustment plate, a lamp holder, and LED lamp cores. On the one hand, it uses a hexagonal truncated pyramid structure lamp holder arranged in a ring to install multiple LED lamp cores, thereby achieving multi-directional and multi-angle illumination output. This effectively solves the problem of uneven light intensity distribution caused by the single light source layout and fixed illumination direction of existing devices, and significantly improves the uniformity of photon flux in each region of the reaction liquid. On the other hand, by adjusting the adjustment drive assembly to drive the adjustment plate to rise and fall, the distance between the LED lamp core and the reaction liquid can be dynamically adjusted according to the reaction requirements, flexibly optimizing the optical path length, reducing the loss of photons due to absorption or scattering on the surface of the solution, and greatly improving the photon utilization rate and the overall reaction rate.

[0023] (2) The present invention utilizes the coordinated operation of a rotating shaft, a mixing drive assembly, a fixed sleeve, a small mixing blade, a mixing rod, and a large mixing blade. When the mixing drive assembly drives the rotating shaft to rotate, it simultaneously drives the small mixing blade and the large mixing blade to rotate, forming a bidirectional stirring and convection effect. This can quickly break the static state of the reaction liquid, allowing the reaction liquid to fully contact the light-illuminated area and avoid local light blind spots. It can also promote the transfer and uniform mixing of substances inside the reaction liquid and reduce the influence of concentration gradient on the reaction.

[0024] (3) The present invention achieves efficient heat conduction by working together with the temperature control cylinder, water inlet pipe, semiconductor cooling chip, circulation mechanism and heat sink. The temperature control cylinder with metal thermal conductivity material achieves efficient heat conduction. The semiconductor cooling chip quickly adjusts the temperature of the medium in the temperature control cylinder.

This achieves precise and stable control of the reaction temperature, provides a suitable temperature environment for metal-organic chemical photoreaction, and ensures the activity of the catalyst and the selectivity of the reaction.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] As attached Figure 1 To be continued Figure 8 As shown:

[0038] Example 1:

[0039] This invention provides a metal-organic chemical photoreactor, comprising a reactor 1;

[0040] The mixing mechanism 2 is installed between the top inner wall and the bottom inner wall of the reactor 1, and the central axis of the mixing mechanism 2 coincides with the central axis of the reactor 1 to ensure that the reaction liquid is subjected to uniform force during the mixing process.

[0041] The illumination mechanism 3 is installed on the upper part of the outer wall of the mixing mechanism 2. The illumination mechanism 3 is located in the middle and upper region inside the reactor 1 and can cover the main reaction space inside the reactor 1.

[0042] The lighting mechanism 3 includes a fixed frame 31, three adjustment drive components 32, an adjustment plate 33, multiple lamp holders 34, and multiple LED lamp cores 35. The three adjustment drive components 32 are respectively installed around the top of the fixed frame 31. The adjustment drive components 32 are cylinders or electric push rods used to drive the adjustment plate 33 to move up and down. The adjustment plate 33 is installed between the bottom ends of the three adjustment drive components 32. The multiple lamp holders 34 are all installed at the bottom end of the adjustment plate 33. The multiple LED lamp cores 35 are respectively installed on the outer wall of the multiple lamp holders 34.

[0043] Temperature control mechanism 4 is installed on the outer wall of reactor 1 and is fitted to the outer wall of reactor 1 to improve heat transfer efficiency;

[0044] A light-transmitting isolation plate 10 is installed on the upper inner wall of the reactor 1. Its material is selected from at least one of quartz glass, borosilicate glass, optical glass, transparent polymer material or sapphire. The edge of the light-transmitting isolation plate 10 is sealed to the inner wall of the reactor 1 to achieve complete isolation between the light-illuminating mechanism 3 and the reaction area.

[0045] The lighting mechanism 3 also includes a spline sleeve 36, a spline cylinder 37, and multiple limit frames 38. The spline sleeve 36 is embedded in the middle of the top of the adjustment plate 33. The spline cylinder 37 passes through the middle of the top of the fixed frame 31 and is sleeved on the upper part of the outer wall of the mixing mechanism 2. The multiple limit frames 38 are all installed around the top of the fixed frame 31.

[0046] A feed pipe 5 is provided on the upper side of the outer wall of reactor 1, and discharge pipes 6 are provided on both sides of the bottom end of reactor 1. A limiting groove 7 is opened on the outer side of the top inner wall of reactor 1. The limiting groove 7 is slidably connected to multiple limiting frames 38 to improve the stability of the fixed frame 31 during rotation. A controller 8 is installed on the front side of the top of reactor 1, and four support legs 9 are installed around the bottom of reactor 1.

[0047] Light intensity sensors are installed on the inner wall of reactor 1 and on the light-transmitting isolation plate 10 to detect the actual light intensity in the reaction chamber in real time. In-situ ultraviolet-visible spectral sensors are installed on the side wall of reactor 1 and on the light-transmitting isolation plate 10 to collect the spectral changes of the reaction liquid in situ. A fluorescence sensor is installed inside reactor 1 near the light-transmitting area to monitor the fluorescence signal of the reaction system to reflect the reaction process. Temperature sensors are installed inside the temperature control cylinder 41 and on the outer wall of reactor 1 to detect the temperature of the reaction liquid and the temperature control medium. A light source power sensor is installed near the lamp holder 34 and the LED lamp core 35 of the illumination mechanism 3 to monitor the output power of the light source. All sensors are used to monitor the light intensity distribution, absorbance change, reaction process, temperature change and light source status inside the reaction liquid, and transmit the detection signals to the controller 8 to realize real-time feedback adjustment of light intensity, light source power and reaction temperature. The controller 8 dynamically adjusts the brightness and lifting position of the light source in the illumination mechanism 3 according to the real-time data, thereby realizing uniform light intensity distribution, optical path optimization and photon utilization improvement.

[0048] The spline sleeve 36 and the spline cylinder 37 are slidably connected to achieve stable lifting and lowering of the adjustment plate 33 in the vertical direction. The lamp holder 34 is set as a hexagonal frustum structure, with each side being an inclined surface. Multiple lamp holders 34 are arranged in a ring, so that the illumination of the LED lamp core 35 can form a superimposed coverage effect. The middle part of the frame of the fixing bracket 31 is set as a herringbone structure to ensure the structural strength of the fixing bracket 31.

[0049] The controller 8 is electrically connected to the mixing mechanism 2, the illumination mechanism 3 and the temperature control mechanism 4 respectively, which can realize the coordinated control of each mechanism. The inner wall of the reactor 1 is coated with a high reflectivity material, which is a polytetrafluoroethylene coating or an aluminum foil reflective film. Its reflectivity is not less than 95% in the ultraviolet-visible light band required for the reaction, which can reflect the scattered light back to the reaction area and greatly improve the utilization rate of light energy.

[0050] Working principle: Before the reaction, the reaction liquid is injected into the reactor 1 through the feed pipe 5. The light-transmitting isolation plate 10 realizes non-contact irradiation between the light source and the reaction liquid, avoiding the hidden dangers of overheating and corrosion caused by direct contact between the light source and the reaction liquid, and ensuring the stability of the device operation. After the device is started, the controller 8 synchronously controls the operation of the mixing mechanism 2, the illumination mechanism 3, and the temperature control mechanism 4. In the illumination mechanism 3, the hexagonal truncated pyramid structure lamp holder 34 arranged in a ring is equipped with multiple LED lamp cores 35, which can output multi-directional and multi-angle illumination, effectively solving the problem of uneven light intensity distribution caused by the single light source layout and fixed illumination direction of the existing device, and significantly improving the uniformity of photon flux in each area of ​​the reaction liquid. At the same time, in conjunction with the high reflectivity material coated on the inner wall of the reactor 1, the reaction liquid is further enhanced. This process reduces light energy loss and enhances the light excitation effect. In addition, the three adjustment drive components 32 can drive the adjustment plate 33 to rise and fall along the sliding fit direction of the spline sleeve 36 and the spline cylinder 37, dynamically adjusting the distance between the LED lamp core 35 and the reaction liquid according to the reaction requirements, flexibly optimizing the optical path length, reducing the loss of photons absorbed or scattered on the solution surface, and significantly improving photon utilization and overall reaction rate. The operation of the mixing mechanism 2 keeps the reaction liquid flowing, ensuring uniform light exposure in each area. The temperature control mechanism 4 maintains a suitable reaction temperature. After the reaction is completed, the reaction products are discharged through the discharge pipe 6. The entire process is centrally controlled by the controller 8 to achieve coordinated linkage of light, mixing, and temperature control, further improving reaction efficiency and product uniformity.

[0051] Example 2:

[0052] This embodiment is basically the same as the previous embodiment, except that the mixing mechanism 2 includes a rotating shaft 21, a mixing drive assembly 22, a fixed sleeve 23, small mixing blades 24, multiple mixing rods 25, and large mixing blades 26. The rotating shaft 21 is installed between the top inner wall and the bottom inner wall of the reactor 1 through bearings. The rotating shaft 21 is also connected to the light-transmitting isolation plate 10 through bearings, and the bearings adopt a sealed structure to prevent the reaction liquid from seeping out. The mixing drive assembly 22 is installed at the top of the rotating shaft 21. The mixing drive assembly 22 adopts a servo motor or a pneumatic motor to drive the rotating shaft 21 to rotate. The fixed sleeve 23 is installed on the lower side of the outer wall of the rotating shaft 21. The small mixing blades 24 are installed on the outer wall of the fixed sleeve 23. The multiple mixing rods 25 are all installed on the outer wall of the fixed sleeve 23. The large mixing blades 26 are installed between the other ends of the multiple mixing rods 25.

[0053] Both the small mixing blade 24 and the large mixing blade 26 are designed with a spiral structure, and the spiral directions of the small mixing blade 24 and the large mixing blade 26 are opposite. During rotation, they can form an up-and-down convection stirring effect. Multiple mixing rods 25 are arranged in a spiral shape along the outer wall of the fixed sleeve 23, and their spiral direction is consistent with that of the large mixing blade 26, which further enhances the turbulence of the reaction liquid, allowing the reaction liquid to fully contact the light and avoiding uneven illumination caused by local reaction liquid standing.

[0054] Working principle: During the reaction, the controller 8 activates the mixing drive component 22 of the mixing mechanism 2, causing the rotating shaft 21 to drive the fixed sleeve 23 to rotate. Simultaneously, the splined cylinder 37 and the splined sleeve 36 work together to drive the illumination mechanism 3 to rotate. The illumination mechanism 3 rotates synchronously with the rotating shaft 21, enabling the multiple LEDs 35 on the hexagonal truncated pyramid structure lamp holder 34 to form dynamic scanning illumination. This allows the light to evenly sweep across every part of the reaction liquid in the reactor 1, completely avoiding localized blind spots and significantly improving the uniformity of light intensity distribution. At the same time, it extends the effective propagation path of photons in the reaction liquid, further improving photon utilization. The rotating shaft 21 synchronously drives the small mixing blades 24. Multiple spirally arranged mixing rods 25 and large mixing blades 26 rotate. Since the small mixing blades 24 and the large mixing blades 26 adopt opposite spiral directions, a bidirectional convection stirring effect can be formed. This can quickly break the static state of the reaction liquid, allowing the reaction liquid to fully contact the dynamic light-irradiated area, and promote the transfer and uniform mixing of substances inside the reaction liquid. It can also reduce the influence of concentration gradient on the reaction, so that the reaction liquid in the reactor 1 can be fully turbulent and mixed evenly. This bidirectional convection stirring and the dynamic rotation irradiation of the light-irradiation mechanism 3 work together to further improve the stability of the reaction rate and the uniformity of the reaction products, and achieve the optimized linkage of mixing effect and light effect.

[0055] Example 3:

[0056] This embodiment is basically the same as the previous embodiment, except that the temperature control mechanism 4 includes a temperature control cylinder 41, a water inlet pipe 42, a semiconductor refrigeration chip 43, a circulation mechanism 44, and multiple heat sinks 45. The temperature control cylinder 41 is sleeved on the outer wall of the reactor 1. The temperature control cylinder 41 has an annular hollow structure. The water inlet pipe 42 passes through the upper side of the outer wall of the temperature control cylinder 41. The semiconductor refrigeration chip 43 is installed on the bottom inner wall of the temperature control cylinder 41, with its cooling surface facing the inside of the temperature control cylinder 41 and its heating surface facing the outside. The circulation mechanism 44 is installed on the top inner wall of the temperature control cylinder 41. Multiple heat sinks 45 are all installed at the bottom end of the semiconductor refrigeration chip 43, and the bottom ends of multiple heat sinks 45 all penetrate the bottom inner wall of the temperature control cylinder 41.

[0057] The circulation mechanism 44 includes a circulation pump 441, an isolation pad 442, a water supply pipe 443, a fixed pipe 444, and multiple diverter heads 445. The isolation pad 442 is installed at the bottom of the circulation pump 441, and the bottom of the isolation pad 442 is installed at the top of the thermoelectric cooler 43. The isolation pad 442 is made of insulating material, which can achieve physical isolation between the circulation pump 441 and the thermoelectric cooler 43. The water supply pipe 443 is installed at the top of the circulation pump 441, and the fixed pipe 444 is installed at the other end of the water supply pipe 443. The top of the fixed pipe 444 passes through the top inner wall of the temperature control cylinder 41. Multiple diverter heads 445 are all installed at the bottom of the fixed pipe 444.

[0058] The fixed tube 444, the semiconductor cooling chip 43, and the temperature control cylinder 41 are all set as annular structures, and the fixed tube 444, the semiconductor cooling chip 43, and the temperature control cylinder 41 are concentrically arranged and coincide with the central axis of the reactor 1, ensuring that the temperature control medium can uniformly wrap the outer wall of the reactor 1 to achieve all-round uniform temperature control. The water supply pipe 443 is set as a spiral structure, which can increase the flow path of the temperature control medium and improve the heat exchange efficiency. The temperature control cylinder 41 is made of metal thermally conductive material to improve the heat exchange effect. Its outer wall is also wrapped with a heat insulation layer to reduce heat loss and improve temperature control accuracy.

[0059] Working principle: After the reaction starts, the controller 8 synchronously regulates the mixing mechanism 2, the illumination mechanism 3, and the temperature control mechanism 4 to operate in coordination. In the temperature control mechanism 4, the temperature control medium is injected into the temperature control cylinder 41 made of metal heat-conducting material through the water inlet pipe 42. After the semiconductor cooling chip 43 starts, it precisely adjusts the temperature of the temperature control medium. Multiple heat sinks 45 accelerate heat dissipation to ensure cooling efficiency. The circulation pump 441 of the circulation mechanism 44 operates stably under the protection of the isolation pad 442, transporting the temperature control medium through the spiral water pipe 443 to the annular fixed pipe 444, and then evenly distributing it to each area of ​​the temperature control cylinder 41 through multiple distribution heads 445. Because the temperature control cylinder 41, the semiconductor cooling chip 43, and the fixed pipe 444 are all in contact with each other, the temperature control medium is effectively controlled. The concentric arrangement of pipes 444 ensures uniform heating or cooling of the outer wall of reactor 1, effectively avoiding local overheating of the reaction liquid caused by heat from the light source or exothermic reaction, achieving precise and stable control of the reaction temperature, providing a suitable temperature environment for the metal-organic photochemical reaction, and ensuring catalyst activity and reaction selectivity. At the same time, the spiral structure of the water supply pipe 443 extends the flow path of the temperature control medium, improves the sufficiency of heat exchange, and further enhances the stability of the temperature control effect. The coordinated linkage of the temperature control mechanism 4, the illumination mechanism 3, and the mixing mechanism 2 comprehensively optimizes the reaction conditions, providing a stable and suitable temperature environment and uniform illumination conditions for the reaction, and significantly improving reaction efficiency and product uniformity.
