However, in actual applications, fixed-structure reactors can only cope with process development under a single condition, and it is difficult to form universality under other processes because its internal structure is difficult to change once it is designed and manufactured, and lacks flexibility and effectiveness. Summary of the Invention

[0004] To address the lack of flexibility and effectiveness of existing technologies mentioned in the background, the present invention provides a microchannel reaction module assembly device that allows microchannel reactors to be flexibly combined according to specific needs, enabling customized configurations for different reaction systems. This helps researchers quickly design and construct appropriate reactor systems based on different reaction requirements.

When multiple reaction modules are provided, the corresponding sequence material inlets are also increased, and react with the material entering the first material inlet in sequence, thereby completing the mixing reaction. Each module has a unified interface and standardized size, which improves the interchangeability and compatibility between modules, making the assembly and disassembly process of the microchannel reactor simpler and more convenient, and the modular design allows the microchannel reactor to be customized according to different reaction requirements to meet the specific needs of different users.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] In the prior art, a microchannel reactor is a three-dimensional structure fabricated from a solid matrix using specialized micromachining techniques and used to carry out chemical reactions. Microchannel reactors typically have small and diverse channels through which fluids flow and within which the desired reactions occur. Microchannel reactors possess a significantly larger surface area than other microstructured chemical equipment, resulting in superior heat and mass transfer capabilities compared to reactors.

[0033] As an advanced reactor design, the core of the microchannel reactor is to use micron-level channels to carry out chemical reactions. This structure enables the reactor to have efficient mass transfer and heat transfer performance, and thus shows significant advantages in the fields of chemical synthesis, drug manufacturing, biological reactions, etc. Microchannel reactors can generally provide a higher specific surface area, increase the surface area and residence time of reactant contact, and thus accelerate the rate of chemical reactions. In addition, due to its small size, microchannel reactors can also quickly reach thermal equilibrium, reduce reaction temperature gradients, reduce the probability of side reactions, and improve product selectivity. However, traditional microchannel reactor designs are often fixed structures, which are difficult to adapt to diverse reaction requirements and difficult to expand on a large scale.

[0034] In current applications, traditional microchannel reactors lack flexibility and effectiveness when dealing with different types of chemical reaction development. Fixed-structure reactors can only cope with process development under a single condition and are difficult to develop for other processes because their internal structure is difficult to change once designed and manufactured. During process development, we often find that even for the same type of reaction with very similar substrates, slight changes in substrate structure often lead to significant differences in reaction time, reaction temperature and other conditions. This makes traditional microchannel reactor designs appear inadequate when faced with diverse reaction conditions and requirements.

[0035] Therefore, in response to the above-mentioned technical problems, the following structure is used in the present embodiment to realize modularization and divide the entire reactor system into multiple independent functional modules, each of which can be designed, manufactured and replaced separately. According to the actual reaction development requirements, modules of different types and functions can be flexibly combined to achieve adaptation and optimization to different reaction conditions. In addition, modular design helps to achieve standardization and batch production, reduce manufacturing and maintenance costs, and improve the scalability and reliability of the system. During the production process, the modular reactor can be adjusted according to production needs, increasing or decreasing the number of modules to flexibly adjust output.

[0036] like Figure 1 、 2As shown, a microchannel reaction module assembly device includes a front cover plate 1 and a rear cover plate 3, with a reaction module 2 detachably connected between the front cover plate 1 and the rear cover plate 3. The front cover plate 1 is provided with a first material inlet 11, the reaction module 2 is provided with a sequential material inlet 21, and the rear cover plate 3 is provided with a reaction liquid outlet 31. The reaction module 2 is connected to the first material inlet 11 and the reaction liquid outlet 31. By providing a detachable connection of the reaction module 2, the flexibility of the device can be improved, and the reaction modules 2 can be added or removed according to the usage scenario. The detachable connection includes but is not limited to a bolt connection, a pin connection, a snap connection, a clamp connection, etc., and the first material inlet 11 and the reaction liquid outlet 31 are connected through the reaction module 2, so that the material in the first material inlet 11 can react with the material entering the sequential material inlet 21 after entering. When multiple reaction modules 2 are provided, the corresponding sequential material inlets 21 are also added, and react with the material entering the first material inlet 11 in sequence, thereby completing the mixing reaction. Each module has a unified interface and standardized dimensions, which improves the interchangeability and compatibility between modules, making the assembly and disassembly of the microchannel reactor simpler and more convenient. The modular design allows the microchannel reactor to be customized according to different reaction requirements to meet the specific needs of different users. It improves the flexibility and applicability of use and can be flexibly replaced according to different needs.

[0037] like Figure 1 、 2 As shown, the reaction module 2 includes a mixing module 22 and a delay module 23. The delay module 23 is arranged on the side of the mixing module 22 close to the rear cover 3, and the sequential material inlet 21 is arranged on the mixing module 22. The materials are mixed by the mixing module 22, and the mixed liquid in the mixing module 22 is fully reacted by the delay module 23.

[0038] like Figure 4 As shown, the delay module 23 is provided with a reaction liquid delay channel 231. The reaction liquid delay channel 231 can increase the residence time of the reaction liquid in the delay module 23 to ensure sufficient reaction.

[0039] like Figure 1 As shown, several reaction modules 2 are provided, with insulation modules 4 disposed between adjacent reaction modules 2. The insulation modules 4 include an internal insulation cavity. When multiple reaction modules 2 are provided, insulation modules 4 are disposed between adjacent reaction modules 2 to prevent interference between adjacent reaction modules 2 and improve reaction accuracy. The provision of the insulation cavity enhances the isolation effect of the insulation modules 4, thereby improving reaction accuracy.

[0040] like Figure 1 、 2As shown, the insulation module 4 is provided with an intermediate heat exchange liquid inlet and outlet 41, and the reaction module 2 is provided with a heat exchange channel 24. The heat exchange channel 24, which is provided on the side of the insulation module 4 near the rear cover plate 3, is connected to the intermediate heat exchange liquid inlet and outlet 41. By providing the intermediate heat exchange liquid inlet and outlet 41 on the insulation template, it is no longer necessary to provide an additional heat exchange liquid inlet and outlet 12 on the reaction module. The heat exchange liquid can be circulated by connecting the intermediate heat exchange liquid inlet and outlet 41, so that all reaction modules 2 can be produced in a unified and standardized manner and can be interchanged with the reaction modules 2 provided near the front cover plate 1, thereby controlling production costs and preventing the heat exchange liquid of the front reaction modules 2 from affecting them.

[0041] like Figure 1 、 2 As shown, the reaction module 2 is provided with a heat exchange channel 24, and the front cover plate 1 is provided with a heat exchange fluid inlet and outlet 12, which are connected to the heat exchange channel 24. The heat exchange fluid inlet and outlet 12 provided on the front cover plate 1 is connected to the heat exchange channel 24, thereby ensuring the flow of the heat exchange fluid within the reaction module 2. After entering the heat exchange fluid inlet and outlet 12 of the front cover plate 1, it passes through a reaction module 2 and then exits the heat exchange fluid inlet and outlet 12 of the front cover plate 1, completing the heat exchange fluid flow loop.

[0042] like Figure 3 As shown, the reaction module 2 is internally provided with a plurality of monomer blocks 201, each of which includes a heat exchange block 25. The heat exchange block 25 is provided with a diffusion heat exchange channel 251 connected to the heat exchange channel 24. The diffusion heat exchange channel 251 increases the heat exchange area, thereby improving the heat exchange efficiency of the heat exchange fluid.

[0043] like Figure 3 As shown, the reaction module includes an inlet hole 261 and an outlet hole 262, both of which are centrally located. The reaction module includes a mixing channel 27, which includes a mixing outlet 271 connected to the outlet hole 262. The mixing channel 27 includes a mixing zone 272 offset from the line connecting the inlet and outlet hole 262. The mixing zone 272 is connected to the sequential material inlet 21. The mixing zone 272 includes an offset hole 273 connected to the inlet hole 261. An offset channel 28 is provided between the offset hole 273 and the inlet hole 261. Through this arrangement, most of the reaction liquid flow holes can be centrally located.

[0044] The assembly and working process of a microchannel reaction module assembly device in this embodiment is as follows: in this embodiment, two groups of reaction modules 2 are provided, and the two groups of reaction modules 2 are connected to the front cover plate 1 and the rear cover plate 3 by bolts. A number of connection holes are provided on the front cover plate 1 and the rear cover plate 3, and connection holes are also provided at the corresponding positions of the reaction modules 2. During the connection and disassembly process, the bolts are aligned with the connection holes and inserted and tightened in sequence to complete the assembly. In actual applications, the number of reaction modules 2 can be increased or decreased according to actual usage requirements. For example, when it is necessary to increase the reaction materials added in the middle, a few additional reaction modules can be added on the basis of this embodiment, connected by the same connection method, and the length of the bolts can be replaced accordingly. Or when only two materials are actually needed to react, the rear reaction module 2 in this embodiment can be removed, and the front cover plate 1 and the rear cover plate 3 can be directly installed in front and behind the front reaction module 2. The materials complete the mixing reaction in only one reaction module 2.

[0045] In this embodiment, each group of reaction modules 2 includes a mixing module 22 and a delay module 23, and an insulation module 4 is arranged between the two groups of reaction modules 2, wherein a cavity is arranged inside the insulation module 4, so that the temperature changes between the front and rear reaction modules 2 can be isolated by the insulation module 4, thereby ensuring that the reaction process of the front and rear groups of reaction modules 2 is maintained within a reasonable range through the heat exchange plate 25, reducing the impact of heat transfer in adjacent reaction modules 2.

[0046] Furthermore, in this embodiment, the mixing module 22 and the delay module in each group of reaction modules 2 are arranged in such a manner that the mixing module 22 is arranged close to one side of the front cover plate 1, and the delay module 23 is arranged close to one side of the rear cover plate 3, that is, the material will first pass through the mixing module 22 and then pass through the delay module 23, wherein the material is mixed in the mixing module 22 and then enters the delay module 23 to extend the fusion time of the two materials to ensure sufficient reaction of the two materials. The delay modules 23 can be increased or decreased as needed, and the time for the two materials to react after mixing in the mixing module 22 is increased by adding multiple delay modules 23. Since the modules in this embodiment are connected in a detachable manner, they can be flexibly changed according to the actual reaction time. At the same time, if the reaction can be completed quickly, the delay module 23 in the reaction module 2 can be directly removed and the mixing module 22 can be directly connected to the rear cover plate 3. If a multi-step reaction is required, an appropriate number of mixing modules 22 can be added directly behind the mixing module 22 as needed and then connected to the rear cover plate 3 to complete the adjustment.

[0047] The front cover plate 1 is provided with a first material inlet. The material enters the front cover plate 1 through the first material inlet 11 and then enters the subsequent mixing module 22 and delay module 23 in sequence. The mixing module 22 is provided with a sequential material inlet 21. After the material entering the sequential material inlet 21 and the material entering from the front cover plate 1 are mixed in the mixing module 22, the reaction liquid is discharged through the subsequent delay module 23 or the rear cover plate 3.

[0048] Furthermore, in the present embodiment, a single plate 201 is provided inside the mixing module 22 and the delay module 23, that is, each mixing module 22 or the delay module 23 is composed of a plurality of single plates 201, wherein the mixing module 22 includes end cover plates arranged on both sides, and two heat exchange plates 25 between the end cover plates, and a mixing plate is sandwiched between the two heat exchange plates 25, wherein a mixing channel 27 is provided on the mixing plate, and an outlet hole 262 and an inlet hole 261 are provided on the end cover plate, wherein the outlet hole 262 is aligned with the inlet hole 261 and is centrally arranged, and the mixing channel 27 includes a mixing outlet 271, wherein the setting of the mixing outlet 271 is aligned with the setting position of the outlet hole 262 and the inlet hole 261, and is also centrally arranged, and the mixing zone 272 of the mixing channel 27 is offset relative to the mixing outlet 271, and the mixing The combining area 272 is connected to the sequential material inlet 21. At the same time, an offset hole 273 is also provided on the mixing area 272, and the offset hole 273 is connected to the inlet 261. Since the mixing area 272 as a whole is offset compared to the inlet 261, an offset flow channel 28 is provided between the offset hole 273 and the inlet 261. In this embodiment, the offset flow channel 28 is a waist-shaped groove structure provided on the heat exchange plate 25, one end of the waist-shaped groove is connected to the inlet 261, and the other end of the waist-shaped groove is provided with an opening connected to the offset hole 273, so that the material entering the inlet 261 produces a horizontal flow through the waist-shaped groove, and then enters the offset hole 273 and the material in the sequential material inlet 21 connected to the mixing area 272 undergoes a mixing reaction in the mixing flow channel 27, so that most of the material flow channels between each monomer plate 201 remain in a central setting.

[0049] Furthermore, a diffusion heat exchange channel 251 is provided on the heat exchange plate 25. The diffusion heat exchange channel 251 is an "S"-shaped bend, and a number of protrusions are provided on the diffusion heat exchange channel 251, thereby increasing the contact area between the diffusion heat exchange channel 251 and the heat exchange liquid, thereby improving the heat exchange efficiency. A heat exchange inlet and outlet are provided on the front cover plate 1, and a heat exchange channel 24 is provided on the mixing module 22 and the delay module 23. The heat exchange inlet and outlet are connected through the heat exchange channel 24 to realize the circulation of the heat exchange liquid. When the heat exchange liquid in this embodiment passes through the heat exchange plate 25, part of the heat exchange liquid enters the diffusion heat exchange channel 251 on the heat exchange plate 25, and part flows backward through the heat exchange channel 24.

[0050] Furthermore, in this embodiment, a heat exchange plate 25 is also provided in the delay module 23, and a reaction liquid delay channel 231 is also provided. The shape of the reaction liquid delay channel 231 is an "S"-shaped bend structure, so that the retention time of the reaction liquid in the delay module 23 can be extended to the greatest extent, ensuring sufficient reaction. Furthermore, a flow-blocking tooth is provided in the reaction liquid delay flow channel, so as to further slow down the flow rate of the reaction liquid, thereby ensuring sufficient reaction, and achieving a stirring effect and improving the reaction quality.

[0051] In the present embodiment, modular design allows micro passage reactors to be flexibly combined according to specific needs to achieve customized configurations for different reaction systems. Such flexibility helps researchers to quickly design and build suitable reactor systems according to different reaction requirements. Through modular design, each module of the micro passage reactor can have a unified interface and standardized size, improves the interchangeability and compatibility between modules, and is conducive to the repeatability of experimental results and the standardized control of reaction conditions. Modular design makes the assembly and disassembly process of the micro passage reactor simpler and more convenient, and the operator can easily replace or adjust the various modules of the reactor as needed, saving operation time and labor cost. Through modular design, the design and performance of each module can be selected and optimized for different reaction requirements, thereby achieving the most optimized regulation and improvement of the operating efficiency and performance of the reactor, and achieving higher reaction efficiency and product quality. Modular design makes the micro passage reactor easier to use and operate, and reduces technical barriers.

[0052] The modular design makes microchannel reactors more flexible and customizable, lowering the barrier to entry. The modular design makes microchannel reactors easier to assemble and adjust, saving time and effort, reducing experimental operational difficulty and costs, and improving experimental efficiency and output. The modular design allows microchannel reactors to be customized to meet the specific needs of different users based on different reaction requirements. This modular design enables modular production and standardized design of microchannel reactors, reducing production costs and improving product quality and consistency.

[0053] Example 2:

[0054] like Figure 5 As shown, unlike Example 1, the reaction module in this embodiment includes a temperature-controlled single plate 29, which is provided with a temperature-controlled flow channel 291. The temperature-controlled flow channel 291 is connected to the first material inlet and / or the sequential material inlet 21. By providing a perforated single plate, the material can be pre-cooled or pre-heated before entering the mixing flow channel 27, thereby improving the accuracy and efficiency of the reaction.

[0055] In this embodiment, the mixing module 22 is not only provided with an end cover plate, a heat exchange plate 25, and a mixing plate, but also provided with a temperature control monomer plate 29, wherein the temperature control monomer plate 29 is arranged before the material enters the mixing channel 27, and the temperature control monomer plate 29 is adjacent to the heat exchange plate 25, and a temperature control channel 291 is provided on the temperature control monomer plate 29. The setting shape of the temperature control channel 291 is an "S"-shaped bend structure, wherein the temperature control monomer plate 29 connects the first material inlet 11 and the sequential material inlet 21. Therefore, in this embodiment, two temperature control monomer plates 29 are provided inside each mixing module 22, so that the material can fully complete heat exchange with the heat exchange plate 25 before entering the mixing channel 27, thereby achieving pre-cooling and preheating effects.

[0056] Furthermore, a through-hole slot is provided on the heat exchange plate 25 connected to the mixing channel 27 near the side of the front cover plate 1. The material passes through the through-hole slot before entering the mixing zone 272. A temperature monitoring device can be set here to monitor the temperature before the reaction.
