Description

Technical Field

[0001] This invention belongs to the field of photochemical reaction technology, and relates to a photochemical continuous reactor, and more particularly to a photochemical continuous reactor with high light energy utilization and wide temperature control range. Background Technology

[0002] Photochemistry, an interdisciplinary field of optics and organic chemistry, generally refers to chemical reactions involving photons. It exhibits excellent selectivity and can be carried out at ambient temperature and pressure, and has been widely applied in biomedicine, materials science, and chemical engineering. Examples include the use of photocatalytic oxidation to treat organic matter in wastewater and the photocatalytic reduction and recovery of metal ions. As a key piece of equipment in photochemical production, the performance of the photochemical reactor plays a crucial role in the application of the photochemical reaction process.

[0003] However, compared with traditional chemical reactions, photochemical production in batch reactors has disadvantages such as uneven light radiation, untimely heat removal, and numerous byproducts. Continuous flow provides an effective solution for photochemical production and has been used in the ton-scale chemical production of multiple pharmaceutical intermediates. However, continuous flow photochemical production still faces two challenges: (1) low light energy utilization; (2) difficulty in achieving ultra-low temperature or ultra-high temperature production.

[0004] CN 101337174A discloses an enhanced photochemical reactor. The reactor includes an outer shell, a quartz sleeve, and a light source. The light source is housed within the quartz sleeve and positioned at the center of the outer shell. The quartz sleeve and the outer shell are connected by a flange and a seal. The outer shell consists of a straight pipe section and a vortex section, with an inlet and an outlet at both ends. The distance between the straight pipe section and the quartz sleeve is 1mm to 50mm, the length of the straight pipe section is 50mm to 500mm, and the height and width of the vortex section are both 5mm to 50mm. This patent addresses the mass transfer limitations encountered during industrial scale-up of photochemical reaction processes by incorporating a vortex section into the outer shell. CN 116159505A discloses a multi-channel photochemical continuous flow microreactor system. The reactor system includes: an inlet distribution channel, a parallel reaction channel group, an outlet collection channel, and a light source, all connected sequentially. The parallel reaction channel group includes multiple transparent reaction channels arranged in parallel, and the light source irradiates these channels. The inlet distribution channel includes an inlet pipe and multiple branch inlet pipes arranged in parallel, with their inlet ends connected to the outlet ends of the inlet pipe. The outlet collection channel includes an outlet pipe and multiple branch outlet pipes arranged in parallel, with their outlet ends connected to the inlet ends of the outlet pipe. This patent employs a simple and easy-to-implement "parallel scale-up + size scale-up" production mode, shortening the reactor scale-up time and increasing product yield.

[0005] The aforementioned patents do not effectively address the shortcomings such as low light energy utilization and limited applicable temperature range. Therefore, it is necessary to provide a photochemical continuous reactor with high light energy utilization and a wide temperature control range to solve the problem of low light energy utilization and achieve photochemical production at ultra-low or ultra-high temperatures. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a photochemical continuous reactor, which solves the problem of low light energy utilization in photochemical reactions and effectively realizes photochemical production at ultra-low or ultra-high temperatures.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] This invention provides a photochemical continuous reactor, the photochemical continuous reactor comprising: an outer shell;

[0009] The outer casing includes a reactor cavity and sealing caps that are independently disposed at both ends of the reactor cavity;

[0010] Inside the reactor cavity, a light-emitting device, a transparent sleeve, and a reaction tube assembly are arranged sequentially from the center outwards.

[0011] This invention improves light energy utilization and enables ultra-low temperature or ultra-high temperature production by rationally positioning the light-emitting device and reaction tube assembly.

[0012] As a preferred embodiment of the present invention, the temperature control range of the photochemical continuous reactor is -75 to 180°C, for example, it can be -75°C, -60°C, -50°C, -25°C, 0°C, 25°C, 50°C, 100°C, 150°C or 180°C, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0013] Preferably, the temperature control range of the photochemical continuous reactor is -20 to 50°C, for example, it can be -20°C, -10°C, 0°C, 10°C, 20°C, 30°C, 40°C or 50°C, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0014] As a preferred embodiment of the present invention, the outer surface of the sealing cap is provided with a reaction liquid inlet and a reaction liquid outlet.

[0015] Preferably, a heat exchange medium inlet is provided at the bottom end of the reactor cavity.

[0016] Preferably, a heat exchange medium outlet is provided at the top of the reactor cavity.

[0017] In this invention, the cavity inside the outer shell can be regarded as a heat exchange jacket. In the reactor cavity, the reaction liquid flows in the reaction tube assembly, and the heat exchange medium flows in the gaps of the reaction tube assembly. The temperature of the reaction liquid in the reaction tube assembly can be controlled by the heat exchange medium. That is, this invention achieves ultra-low temperature or ultra-high temperature photochemical production by adjusting the type of heat exchange medium.

[0018] As a preferred embodiment of the present invention, the reaction tube assembly includes at least 10 reaction tubes arranged in a cross pattern; the number of reaction tubes is ≥10, for example, it can be 10, 12, 14, 16, 18 or 20, etc., but is not limited to the listed values, and other unlisted values ​​within the range are also applicable.

[0019] Preferably, the number of reaction tubes arranged in layers is 2 to 10, for example, 2, 3, 4, 5, 6, 7, 8, 9 or 10 layers.

[0020] Preferably, the center distance between two adjacent reaction tubes is ≤ twice the inner diameter of the reaction tube, for example, it can be 2 times, 1.8 times, 1.6 times, 1.4 times or 1.2 times, etc., but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0021] In this invention, by rationally designing the arrangement of the reaction tubes, all reaction tubes can be directly illuminated by the light source of the light-emitting device, thereby ensuring that all light is completely absorbed by the reaction liquid, thus improving the light energy utilization rate.

[0022] Furthermore, if the center distance between two adjacent reaction tubes is greater than twice the inner diameter of the reaction tube, it will lead to a decrease in light utilization.

[0023] Preferably, the distance between the reaction tube and the light-emitting device is 1 to 100 mm, for example, it can be 1 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm or 100 mm, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0024] In this invention, the distance between the reaction tube and the light-emitting device is set to 1 to 100 mm, which can both enable the flow of heat exchange medium in the reactor cavity and avoid the reaction tube being too far from the light source and the light being too weak.

[0025] As a preferred embodiment of the present invention, the material of the reaction tube includes any one of quartz, glass, PFA, PTFE, FEP, PMMA or PDMS, preferably quartz.

[0026] Preferably, the inner diameter of the reaction tube is 2mm to 10cm, for example, it can be 2mm, 10mm, 2cm, 4cm, 6cm, 8cm or 10cm, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0027] Preferably, the wall thickness of the reaction tube is 0.5 to 10 mm, for example, it can be 0.5 mm, 1 mm, 2 mm, 4 mm, 6 mm, 8 mm or 10 mm, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0028] Preferably, the length of the reaction tube is 10cm to 5m, for example, it can be 10cm, 50cm, 1m, 2m, 3m, 4m or 5m, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0029] As a preferred embodiment of the present invention, the two ends of the reaction tube are each provided with a sealing device independently.

[0030] Preferably, the sealing device includes a metal ring, and a first sealing ring and a second sealing ring disposed at both ends of the metal ring.

[0031] Preferably, the first sealing ring is disposed on the side close to the sealing cover.

[0032] Preferably, the width of the metal ring is 1.5 to 2 mm, for example, it can be 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2 mm, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0033] In this invention, the first sealing ring is used to isolate the heat exchange medium from the air, thereby preventing leakage of the heat exchange medium; the second sealing ring is used to isolate the reaction liquid from the air, thereby preventing leakage of the reaction liquid.

[0034] More specifically, the present invention forms a conical sealing surface on the surface of the reaction tube by means of a first sealing ring, a metal ring, and a second sealing ring, and achieves the sealing process by compressing the reaction tube, the sealing ring, and the conical sealing surface.

[0035] Preferably, the reactor cavity further includes baffles for fixing the reaction tubes and agitating the heat exchange medium, thereby making the heat exchange more uniform and improving the reaction efficiency.

[0036] As a preferred embodiment of the present invention, the light source wavelength of the light-emitting device is 180-500nm, for example, it can be 180nm, 200nm, 250nm, 300nm, 350nm, 400nm, 450nm or 500nm, but is not limited to the listed values, and other unlisted values ​​within the range are also applicable; preferably 300-370nm.

[0037] Preferably, the light-emitting device includes any one of a low-pressure mercury lamp, a medium-pressure mercury lamp, a high-pressure mercury lamp, or an LED light source, with a low-pressure mercury lamp being the most preferred.

[0038] As a preferred embodiment of the present invention, the photochemical continuous reactor further includes a temperature detection port.

[0039] Preferably, the number of temperature detection ports is 1 to 6, for example, 1, 2, 3, 4, 5 or 6, but not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0040] Preferably, the temperature detection port is used to detect the temperature of the reaction liquid inside the reaction tube assembly.

[0041] More specifically, the present invention allows a temperature detector to be installed inside the reaction tube via a temperature detection port, thereby enabling real-time monitoring of the temperature of the reaction liquid inside the reaction tube;

[0042] As a preferred embodiment of the present invention, a viewing window is provided on the surface of the outer casing.

[0043] Preferably, the number of windows is 1 to 6, for example, 1, 2, 3, 4, 5 or 6, but not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0044] As a preferred embodiment of the present invention, the heat exchange medium in the reactor cavity includes any one of water, ethanol, glycerol, phenyl silicone oil, or dimethyl silicone oil.

[0045] Preferably, the temperature of the heat exchange medium is -80 to 200°C, for example, it can be -80°C, -50°C, 0°C, 50°C, 100°C, 150°C or 200°C, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0046] This invention controls the temperature of the reaction liquid in the reaction tube by controlling the temperature of the heat exchange medium. Therefore, in order to achieve photochemical reactions over a wide temperature range, the heat exchange medium should have a high boiling point or a low crystallization temperature and high light transmittance.

[0047] The numerical range described in this invention includes not only the point values ​​listed above, but also any point values ​​within the numerical ranges not listed above. Due to space limitations and for the sake of brevity, this invention will not exhaustively list all the specific point values ​​included in the range.

[0103] Example 4

[0104] This embodiment provides a photochemical continuous reactor, which differs from the one in Embodiment 1 only in that:

[0105] In this embodiment, the center distance between two adjacent reaction tubes is adjusted to 2.5 times the inner diameter of the reaction tube.

[0106] Compared to Example 1, this example increases the center distance between two adjacent reaction tubes, which reduces the number of quartz tubes arranged, thereby reducing the light energy utilization rate.

[0107] Example 5

[0108] This embodiment provides a photochemical continuous reactor, which differs from the one in Embodiment 1 only in that:

[0109] In this embodiment, the cross arrangement of the reaction tubes is adjusted to an overlapping arrangement.

[0110] Compared with Example 1, in this example, except for the first layer of reaction tubes near the light-emitting device, the other reaction tubes cannot achieve direct illumination of the light source, resulting in a decrease in light energy utilization.

[0111] Example 6

[0112] This embodiment provides a photochemical continuous reactor, which differs from the one in Embodiment 1 only in that:

[0113] In this embodiment, the distance between the reaction tube and the light-emitting device is adjusted to 50-120 mm.

[0117] The first sealing ring is omitted in this embodiment.

[0118] Compared with Example 1, omitting the first sealing ring in this example will cause leakage of the heat exchange medium, reduce the heat exchange efficiency in the reactor, and prevent the photochemical reaction from reaching the specified reaction temperature quickly and accurately, thus reducing the reaction efficiency.

[0119] Example 8

[0120] This embodiment provides a photochemical continuous reactor, which differs from the one in Embodiment 1 only in that:

[0123] Comparative Example 1

[0124] This comparative example provides a photochemical continuous reactor, which differs from Example 1 only in that:
