Description

Technical Field

[0001] The present invention relates to the technical field of photoreaction, and in particular to a flow channel structure and an efficient reactor applied to photoreaction. Background Art

[0002] The so-called photoreaction refers to a chemical reaction initiated by an atom, a molecule, a free radical or an ion absorbing a photon.

[0003] Photoreaction, also known as photochemical action, refers to a chemical reaction caused by the action of light on a substance. That is, a chemical reaction that occurs when a substance absorbs light energy under the irradiation of visible light or ultraviolet light. Photoreactions can cause processes such as combination, decomposition, ionization, oxidation-reduction, etc. It can be mainly divided into two categories: one is photosynthesis, such as green plants making carbon dioxide and water absorb light energy with the help of plant chlorophyll under sunlight irradiation and synthesize carbohydrates. The other is photodecomposition, such as molecular oxygen in the upper atmosphere absorbing ultraviolet light and decomposing into atomic oxygen; the fading of dyes in the air, the photosensitive effect of films, etc.

[0004] Traditional photoreactions usually use flat reactors or pipes, but this structure will cause the material to be blocked by light, reducing the reaction efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to solve the technical problem of low reaction efficiency in the prior art, the present invention provides a flow channel structure and an efficient reactor applied to photoreaction.

[0006] In the first aspect, the present application discloses a flow channel structure applied to photoreaction.

[0007] A flow channel structure applied to photoreaction includes two transparent plates. Limiting parts are convexly arranged on the opposite surfaces of the two transparent plates. A plurality of the limiting parts are arranged according to a rule, so that a flow channel is formed between adjacent limiting parts. The flow channels on the two transparent plates are arranged in alignment, and a feed port and a discharge port are arranged on the flow channel.

[0008] The flow channel structure and the efficient reactor applied to photoreaction of the present invention form a flow channel by splicing two transparent plates. On the one hand, the overall processing is relatively convenient and the cost is low. On the other hand, the circumferential dimension of the flow channel is small, and the reaction material flowing in the flow channel is more easily irradiated by light. It is convenient to improve the effect of photoreaction. And the method of forming the flow channel by the limiting parts can further reduce the production cost, simplify the process and reduce the cost because no cutting process is required.

[0009] Further, the flow limiting member includes a first U-shaped wall and a second U-shaped wall. The openings of the first U-shaped wall and the second U-shaped wall are arranged opposite to each other. The first U-shaped wall and the second U-shaped wall are provided with multiple groups along the first direction, and each group of the first U-shaped wall and the second U-shaped wall is provided with multiple ones along the second direction.

[0010] Further, the first U-shaped wall and the second U-shaped wall in the same group are arranged staggeredly along the second direction.

[0011] Further, both the first U-shaped wall and the second U-shaped wall include a main wall and two side walls. The two side walls are oppositely arranged at both ends of the main wall along the second direction, and the two side walls of two adjacent second U-shaped walls that are close to each other are located between the two side walls of the same first U-shaped wall.

[0012] Further, a flow dividing wall is further provided on the main wall. The flow dividing wall of the first U-shaped wall is located between the two second U-shaped walls, and the flow dividing wall of the second U-shaped wall is located between the two first U-shaped walls.

[0013] Further, the flow limiting member is provided with multiple groups along the first direction, and each group of the flow limiting member is provided with multiple ones along the second direction.

[0014] Further, the flow limiting member can be hemispherical, cylindrical or prismatic.

[0015] Further, a limiting frame is provided outside the two transparent plates. Through holes are provided on the limiting frame, and the through holes are aligned with the feed inlet and the discharge outlet.

[0016] In a second aspect, the present application discloses an efficient reactor.

[0017] An efficient reactor includes a dark box. The above-mentioned flow channel structure is provided in the dark box. Two groups of light emitting members are provided in the dark box. The two groups of light emitting members are oppositely arranged on both sides of the flow channel structure along the third direction. A feed pipe and a discharge pipe are provided on the dark box. The feed pipe is connected to the feed inlet, and the discharge pipe is connected to the discharge outlet.

[0018] Further, an adjusting member is provided between the two groups of light emitting members to adjust the distance between the two groups of light emitting members and the flow channel structure.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. By splicing two transparent plates to form a flow channel, on the one hand, the overall processing is relatively convenient and the cost is low. On the other hand, the circumferential dimension of the flow channel is small, and the reaction materials flowing in the flow channel are more easily irradiated by light, which is convenient for improving the effect of the photochemical reaction. And the way of forming the flow channel by the flow limiting member can further reduce the production cost, simplify the process and reduce the cost because no cutting process is required;

[0021] 2. Through the arrangement of the first C-shaped wall and the second C-shaped wall, not only is the distance that the reaction materials need to pass through the flow channel increased, but also the change of the flow channel is more abundant. The reaction materials continuously collide and turn, disperse and converge, and regularly mutate in the flow channel, increasing the turbulence degree of the reaction materials. Moreover, during this process, more reaction materials can be irradiated by light, thereby realizing an efficient and sufficient photochemical reaction.

[0022] 3. Through the arrangement of the flow dividing wall, the turbulence degree of the reaction materials is further enhanced, thereby improving the efficiency and quality of the photochemistry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0033] Example 1

[0034] In a first aspect, the present application discloses a flow channel structure applied to a photochemical reaction.

[0035] Referring to Figure 1 and Figure 2 , a flow channel structure applied to a photochemical reaction includes two transparent plates 1. On the opposite sides of the two transparent plates 1, a plurality of current limiting members 2 are convexly arranged. The current limiting members 2 are arranged in a regular pattern so that a flow channel 3 is formed between adjacent current limiting members 2. The flow channels 3 on the two transparent plates 1 are aligned, and a feed port and a discharge port are provided on the flow channel 3.

[0036] Referring to FIG. 2, the current limiting member 2 includes a first U-shaped wall 21 and a second U-shaped wall 22. The openings of the first U-shaped wall 21 and the second U-shaped wall 22 are arranged opposite to each other. The first U-shaped wall 21 and the second U-shaped wall 22 are arranged in multiple groups along a first direction. Each group of the first U-shaped wall 21 and the second U-shaped wall 22 is arranged in multiple numbers along a second direction. The first U-shaped wall 21 and the second U-shaped wall 22 in the same group are staggered along the second direction.

[0037] Both the first U-shaped wall 21 and the second U-shaped wall 22 include a main wall 211 and two side walls 212. The two side walls 212 are fixedly connected to both ends of the main wall 211 relatively along the second direction. The two side walls 212 of two adjacent second U-shaped walls 22 that are close to each other are located between the two side walls 212 of the same first U-shaped wall 21, so that the flow channel 3 between each group of the first U-shaped wall 21 and the second U-shaped wall 22 has more branches, so that the reaction material is relatively dispersed when entering a group of the first U-shaped wall 21 and the second U-shaped wall 22, and when leaving this group of the first U-shaped wall 21 and the second U-shaped wall 22, the reaction material is relatively converged. When the reaction material flows between multiple groups of the first U-shaped wall 21 and the second U-shaped wall 22, it is constantly repeating the process of dispersion and convergence, which can accelerate the mixing and position exchange of the reaction material, and thus improve the effect and efficiency of the photochemical reaction of the reaction material.

[0038] Referring to Figure 3 , a limiting frame 44 is fixedly connected to the outside of the two transparent plates 1 by bolts for blocking the periphery of the flow channel 3. A through hole 441 is provided on the limiting frame 44, and the through hole 441 is aligned with the feed port and the discharge port for facilitating the passage of the feed pipe 42 and the discharge pipe 43. The number of the current limiting members 2, the positions and numbers of the feed port and the discharge port, etc. can all be designed according to the situation. For example, when the reaction time of the reaction material is short, multiple feed ports and discharge ports can be set or the number of groups of the current limiting members 2 can be reduced; when the reaction time of the reaction material is long, the number of groups of the current limiting members 2 can be increased or the number of the feed port and the discharge port can be reduced.

[0039] The transparent plate can be made of a high-transparency quartz glass plate.

[0040] Working principle: The flow channel 3 is formed by splicing two transparent plates 1. On the one hand, the overall processing is relatively convenient and the cost is low. On the other hand, the circumferential dimension of the flow channel 3 is small, and the reaction materials flowing in the flow channel 3 are more easily irradiated by light, which is convenient for improving the effect of the photochemical reaction. And the method of forming the flow channel 3 by the flow limiting member 2 can further reduce the production cost, simplify the process and reduce the cost because no cutting process is required. At the same time, the flow channel 3 has many branches, which not only makes the flow distance of the reaction materials longer, but also makes the reaction materials relatively dispersed when entering a group of first U-shaped walls 21 and second U-shaped walls 22, and relatively convergent when leaving this group of first U-shaped walls 21 and second U-shaped walls 22. When the reaction materials flow between multiple groups of first U-shaped walls 21 and second U-shaped walls 22, the process of dispersion and convergence is continuously repeated, accelerating the mixing and position exchange of the reaction materials, and then improving the effect and efficiency of the photochemical reaction of the reaction materials.

[0041] Second, the present application discloses a high-efficiency reactor.

[0042] Refer to Figure 4 , a high-efficiency reactor, including a dark box 4, a flow channel structure 5 as described above is fixedly connected inside the dark box 4, two sets of light-emitting members 41 are installed inside the dark box 4, and the two sets of light-emitting members 41 are relatively arranged on both sides of the flow channel structure 5 along the third direction. The dark box 4 is provided with a feed pipe 42 and a discharge pipe 43, the feed pipe 42 is connected to the feed port, and the discharge pipe 43 is connected to the discharge port.

[0043] An adjusting member 45 is provided between the two sets of light-emitting members 41 to adjust the distance between the two sets of light-emitting members 41 and the flow channel structure 5. The light-emitting member 41 includes a mounting plate 411 and an LED lamp 412 mounted on the mounting plate 411. The adjusting member 45 can be a combination of a bolt and a nut. The mounting plates 411 of the two sets of light-emitting members 41 are relatively fixed by bolts and nuts, and the distance is adjusted by bolts and nuts.

[0044] The overall size of the dark box 4 is small. During batch work, the dark boxes 4 can be stacked, so that more reaction materials can be subjected to photochemical reactions in a smaller space.

[0045] Embodiment 2

[0046] Refer to Figure 5 , a flow dividing wall 213 is also fixedly connected to the main wall 211. The flow dividing wall 213 of the first U-shaped wall 21 is located between the two second U-shaped walls 22, and the flow dividing wall 213 of the second U-shaped wall 22 is located between the two first U-shaped walls 21. Such a setting can further increase the branches of the flow channel 3, so that the reaction materials can accelerate the photochemical reaction during continuous collision and turning during the flow process.

[0047] Refer toFigure 6 In another embodiment, the first C-shaped wall 21 and the second C-shaped wall 22 may also be C-shaped.

[0048] Embodiment III

[0049] Referring to Figure 7 , a plurality of current limiters 2 are provided along the first direction, and a plurality of current limiters 2 are provided along the second direction in each group. The current limiter 2 can be hemispherical, cylindrical or prismatic, and corresponding-shaped molds can be used for hot extrusion forming during processing.
