[0033] Reference Figures 1 to 5 The present invention provides a photothermal reaction device, including a light source component 1, a heat collecting tube 2, a reaction tube 3 and a temperature probe 4.

[0034] The heat collecting tube 2 is located at the center of the photothermal reaction device, and a plurality of light source assemblies 1 are distributed circumferentially on the outside of the heat collecting tube 2, and are preferably evenly distributed, thereby forming an annular light source combination. The light source can evenly irradiate the heat collecting tube 2. The annular irradiation method can increase the irradiation energy density of the heat collecting tube 2, improve the irradiation uniformity and axial uniformity, and solve the technical problems of uneven temperature in the reaction zone and unsatisfactory constant temperature effect in the constant temperature zone.

[0035] The light source assembly 1 is provided with a photothermal light source 11 and / or a photoreaction light source 12 capable of irradiating the heat collecting tube 2 along the axial direction of the heat collecting tube 2. With such an arrangement, the light source assembly 1 has a rich combination form, and the light sources for photothermal and photoreaction can also be designed on the same light source assembly 1 when necessary, so that the photothermal reaction device can perform photoreaction, thermal reaction and photothermal integrated reaction;

[0036] Specifically, when only the photothermal light source 11 is provided on all the light source assemblies 1, the photothermal reaction device can be completely used for pure thermal reaction;

[0037] When all light source assemblies 1 are provided with only the light reaction light source 12, the photothermal reaction device can be completely used for pure light reaction;

[0038] When the photothermal light source 11 and the photoreaction light source 12 are simultaneously provided on the same light source assembly 1, or the photothermal light source 11 and the photoreaction light source 12 are respectively provided on different light source assemblies 1, the photothermal reaction device can be used for photothermal integrated reaction. When performing the photothermal integrated reaction, the specific illumination forms include a combined illumination form of circumferential illumination and circumferential heating, a strip illumination form, an internal illumination form, and an end illumination form.

[0039] In this embodiment, the photothermal light source 11 is preferably photothermal lamp beads, and the photoreactive light source 12 is preferably photoreactive lamp beads, and the photothermal lamp beads and / or photoreactive lamp beads are arranged in an array.

[0040] For the photothermal light source 11, a selective heat-absorbing film is plated inside the vacuum layer of the heat collecting tube 2 in the corresponding irradiation range of the photothermal light source 11, and a thermal reaction is carried out through the selective heat-absorbing film in cooperation with the photothermal light source 11;

[0041] For the photoreactive light source 12, the vacuum layer inside the heat collecting tube 2 may not be coated, and the heat collecting tube 2 may directly cooperate with the photoreactive light source 12 to perform photoreaction through its own material and light transmittance. The vacuum layer inside the heat collecting tube 2 may also be coated with a selective light-transmitting film in the corresponding irradiation range of the photoreactive light source 12, and the light-reaction may be performed through the selective light-transmitting film in cooperation with the photoreactive light source 12;

[0042] In this embodiment, the specific forms of the heat collecting tube 2 include but are not limited to a single-pass round-end heat collecting tube, a double-pass local heat collecting tube and a single-pass flat-end heat collecting tube, and the light transmission forms of the heat collecting tube 2 include but are not limited to local light transmission, long strip light transmission and circumferential light transmission;

[0043] In different experiments, different heat collecting tubes 2 can be selected for combination and use according to the actual experimental application scenario.

[0044] In this embodiment, the structure of the photothermal lamp beads and the photoreactive lamp beads includes but is not limited to LED light sources, xenon lamp light sources, mercury lamp light sources, microwave electrodeless lamps, lasers or halogen lamps. The photothermal lamp beads and the photoreactive lamp beads can emit parallel light or convergent light, and are ultraviolet light, infrared light or visible light;

[0045] In different experiments, different photothermal lamp beads and photoreactive lamp beads can be selected and used in combination according to the actual experimental application scenarios.

[0046] The interior of the reaction tube 3 is filled with a photothermal catalyst, and the two ends of the reaction tube 3 respectively form a catalytic gas inlet 31 and a post-reaction gas outlet 32. The main body of the reaction tube 3 is placed inside the heat collecting tube 2 and its two ends pass through the ends of the heat collecting tube 2. The reaction tube 3 located inside the heat collecting tube 2 can perform a photothermal coupling synergistic reaction through high temperature and light.

[0047] In this embodiment, the specific forms of the reaction tube 3 include but are not limited to U-shaped tubes, straight tubes and spiral tubes, and the specific materials of the reaction tube 3 include but are not limited to quartz glass, high borosilicate glass and seamless stainless steel tubes. In different experiments, reaction tubes 3 of different forms and materials can be selected for combination and use according to the actual experimental application scenarios.

[0048] The main body of the temperature probe 4 is placed inside the heat collecting tube 2 , and the temperature probe 4 can detect the temperature inside the heat collecting tube 2 and the temperature of the constant temperature zone in real time.

[0049] The photothermal reaction device is equipped with a ring-shaped light source assembly 1 on the outer side of the heat collecting tube 2, which can provide the heat collecting tube 2 with high irradiation energy density and high irradiation uniformity, thereby improving the constant temperature effect of the constant temperature zone. The light source assembly 1 has a variety of combinations, so that the photothermal reaction device can perform photoreaction, thermal reaction and photothermal integrated reaction. The interior of the heat collecting tube 2 is equipped with a reaction tube 3, and the whole constitutes a photochemical reaction system with high heat collection efficiency. The photothermal reaction device can achieve heating through light, which is cleaner.

[0050] The photothermal reaction device further includes a box body 5, which includes two half boxes 51. One end of the two half boxes 51 is preferably movably connected by a folding hinge 54, and the other end of the two half boxes 51 is preferably detachably connected by a snap lock 55. When the snap lock 55 is in an open state, the upper half box 51 can be rotated relative to the lower half box 51 by the folding hinge 54, thereby exposing the accommodation space between the two half boxes 51.

[0051] The number of light source assemblies 1 is an even number. In this embodiment, the number of light source assemblies 1 is preferably six. Each half box 51 is connected to half the number of light source assemblies 1. Here, the light source assembly 1 is located inside the accommodation space between the two half boxes 51, and is preferably connected to the half boxes 51 by bolts, so that it is easy to disassemble and assemble, and is convenient for the inspection, maintenance and replacement of the light source assembly 1.

[0052] The box body 5 further includes a heat collecting tube limiting structure 52, which is connected to the two half boxes 51. Here, the heat collecting tube limiting structure 52 is located inside the accommodation space between the two half boxes 51, and is preferably connected to the half boxes 51 by bolts. When the two half boxes 51 are connected together, the heat collecting tube limiting structure 52 can limit and fix the heat collecting tube 2. When the two half boxes 51 are disconnected and in an open state, the heat collecting tube limiting structure 52 can release the limit fixation of the heat collecting tube 2. The heat collecting tube limiting structure 52 is preferably a fixed sleeve, and the fixed sleeve has the same cross-sectional shape as the heat collecting tube 2 to form a better limiting effect.

[0053] Through the design of two half boxes 51, the box body 5 is divided into two halves in the middle. When the experiment starts or ends, the heat collecting tube 2 can be put in or taken out after opening the two half boxes 51, making the removal and installation of the heat collecting tube 2 more convenient and quick, and solving the technical problems of difficult replacement and cumbersome operation of the heat collecting tube 2. At the same time, the light source assembly 1 is also evenly distributed on the two half boxes 51. After the two half boxes 51 are locked, they are re-surrounded in the circumferential direction of the heat collecting tube 2 without affecting normal use.

[0054] The box body 5 also includes an auxiliary support structure 56. In this embodiment, the auxiliary support structure 56 is preferably a nitrogen spring. The number of nitrogen springs is preferably two. Both ends of each nitrogen spring are connected to a half box 51. When the snap lock 55 between the two half boxes 51 is in an open state, the upper half box 51 can be rotated relative to the lower half box 51 through the folding hinge 54 with the cooperation of the nitrogen spring. Due to the characteristics of the nitrogen spring, the rotation process is relatively slow and is not easy to cause damage to the structure. At the same time, the nitrogen spring can limit the extreme state of rotation of the upper half box 51 to prevent it from completely turning over and causing the center of gravity of the structure to be unbalanced and overturned.

[0055] The photothermal reaction device also includes a fixed insulation plug 6. When the two half boxes 51 are connected together, an auxiliary hole 53 can be formed at the corresponding positions at both ends of the heat collecting tube 2. According to the specific conditions of different experiments, the fixed insulation plug 6 can be selectively detachably connected to any auxiliary hole 53, or two fixed insulation plugs 6 can be installed on two auxiliary holes 53 at the same time. When necessary, the fixed insulation plug 6 can block the tube mouth of the heat collecting tube 2, reduce the heat dissipation in the tube, and make the temperature of the reaction zone higher and more uniform.

[0056] It is worth noting that for the end of the reaction tube 3 and the end of the temperature probe 4 extending out of the heat collecting tube 2, a fixing hole for fixing the reaction tube 3 and the temperature probe 4 is provided on the fixed insulation plug 6 arranged at this end, so that the structural design is more reasonable and at the same time can form a good fixing and limiting effect on the reaction tube 3 and the temperature probe 4.

[0057] The photothermal reaction device also includes an auxiliary light source. When necessary, an auxiliary light source can be set at the end where the fixed insulation plug 6 is not set. The auxiliary light source is located on the outside of the auxiliary hole position 53 and can illuminate the heat collecting tube 2. The setting method of the auxiliary light source at the auxiliary hole position 53 here can enrich the specific operation method of the photothermal reaction device. The auxiliary light source can be a photothermal light source or a photoreaction light source, and can be flexibly selected and set according to actual conditions.
