Description

Technical Field

[0001] This invention relates to the fields of microchemical engineering and strongly exothermic reactions, specifically a plate microreactor with a high-throughput reflux cooling channel. Background Technology

[0002] Strongly exothermic reactions, such as peroxidation, nitration, and diazotization, are very common in the development and synthesis of products in fields such as fine chemicals, environmental protection, and biomedicine. However, the process of strongly exothermic reactions is accompanied by intense heat release, and heat is easily accumulated locally in the reactor. While causing side reactions, it is also very easy to trigger thermal runaway or even an explosion.

[0003] In the chemical industry, traditional batch reactors are still widely used for highly exothermic reactions. While batch reactors typically employ mechanical stirring and jacketed heat exchange to enhance mass and heat transfer, their overall performance remains poor. Precise temperature control is impossible, leading to mass-heat imbalances, decreased reaction selectivity, and the generation of byproducts, while also posing significant safety hazards. Therefore, a new technology is urgently needed to address the numerous problems associated with traditional reactors.

[0004] Microreactor technology has thus emerged. A microchannel reactor is a flow chemical reactor manufactured using microfabrication technology, with channel sizes ranging from 10µm to 3mm. Due to its small channel size and high specific surface area, microreactors can provide more uniform temperature distribution and stronger mixing effects, thereby improving reaction selectivity and yield, and reducing the formation of local hot spots. Therefore, microreactors have broad application prospects in the chemical industry, especially in strongly exothermic reactions and continuous flow reactions. Through precise control of flow and optimization of reaction conditions, efficient, safe, and sustainable chemical reactions can be achieved. Plate microreactors are a relatively new type of microreactor. Compared to other microreactors, plate microreactors have a more compact design, which gives them an excellent specific surface area, providing a more uniform temperature distribution and reducing the occurrence of local hot spots.

[0005] The most important aspects of plate microreactors are the design of their cooling oil channels and reaction fluid channels, especially the cooling oil channels. Currently, commonly used designs include corrugated plates and curved channels, but these designs generally have drawbacks such as excessive pressure drop, high operating costs, and low cooling oil turbulence. Summary of the Invention

[0006] To address the shortcomings of existing traditional exothermic reaction equipment, this invention provides a plate microreactor with a high-throughput reflux cooling channel, comprising a first cooling plate, a reaction plate, a second cooling plate, and a cover plate stacked sequentially.

[0007] The first cooling plate, reaction plate, second cooling plate, and cover plate are assembled together;

[0008] The first and second cooling plates have the same structure, both equipped with cooling oil channels for the flow of cooling oil. The cooling oil channels of the first cooling plate are located on the side where the first cooling plate is in contact with the reaction plate, while the cooling oil channels of the second cooling plate are located on the side where the second cooling plate is in contact with the cover plate. Each cooling oil channel includes a distribution pipe, a fluid dispersion zone, and a collection pipe. The distribution pipe is used to distribute the cooling oil into the fluid dispersion zone. The collection pipe is used to collect the cooling oil flowing through the fluid dispersion zone. The fluid dispersion zone is provided with multiple intersecting cooling oil dispersion channels. When the cooling oil enters the fluid dispersion zone, it is dispersed into the fluid dispersion zone through the cooling oil dispersion channels. When a stream of cooling oil changes direction through a cooling oil dispersion channel in the fluid dispersion zone and encounters the cooling oil in another cooling oil dispersion channel, it forms a vortex and breaks up the hierarchical structure of the cooling oil, thereby improving the cooling effect.

[0009] The reaction plate is the site where the reaction liquid reacts. A reaction liquid flow channel is provided on the side of the reaction plate that is in contact with the second cooling plate. The reaction liquid flow channel includes a continuous S-shaped channel and multiple micro-reaction chambers formed on the channel. Each micro-reaction chamber is equipped with a flow-blocking baffle and multiple flow-turbulent cylinders. The flow-blocking baffle is located in the center of the micro-reaction chamber and is a herringbone baffle with the central axis of the width direction of the micro-reaction chamber as the axis of symmetry. The number of flow-turbulent cylinders is even, and all flow-turbulent cylinders are symmetrically arranged on both sides of the flow-blocking baffle.

[0010] The cover plate is used to seal the cooling oil flow channels of the second cooling plate.

[0011] As a preferred embodiment of the present invention, multiple rhomboid structures are arranged in an array within the fluid dispersion zone. The rhomboid structures in adjacent rows are staggered and have reserved flow channels for the flow of cooling oil. The front end of each rhomboid structure has a "W"-shaped dispersion flow channel with three ports. After entering from the middle port of the "W"-shaped dispersion flow channel, the cooling oil changes its flow direction in the "W"-shaped dispersion flow channel of the rhomboid structure and flows out from the left and right ports of the "W"-shaped dispersion flow channel. The cooling oil flowing out from the left and right ports meets the cooling oil flowing in the flow channel between the rhomboid structures, thereby forming a vortex and merging.

[0012] As a preferred embodiment of the present invention, cooling oil inlets are provided at the upper positions of the first cooling plate, the reaction plate, and the second cooling plate, and all of the cooling oil inlets are connected together. The cooling oil inlets on the first cooling plate and the second cooling plate are all connected to the front end of their respective cooling oil channels. Cooling oil outlets are provided at the lower positions of the reaction plate, the second cooling plate, and the cover plate, and all of the cooling oil outlets are connected together. The cooling oil outlet of the reaction plate is connected to the end of the cooling oil channel in the first cooling plate, and the cooling oil outlet of the second cooling plate is connected to the end of the cooling oil channel in the second cooling plate.

[0013] As a preferred embodiment of the present invention, the upper part of the first cooling plate and the reaction plate are provided with reaction liquid inlet holes and all of the reaction liquid inlet holes are connected, and the reaction liquid inlet holes of the reaction plate are connected to the front end of the reaction liquid flow channel in the reaction plate; the lower part of the second cooling plate and the cover plate are provided with reaction liquid outlet holes and all of the reaction liquid outlet holes are connected; the reaction liquid outlet holes of the second cooling plate are connected to the tail end of the reaction liquid flow channel in the reaction plate.

[0014] As a preferred embodiment of the present invention, the cooling oil channel size of the second cooling plate is exactly the same as that of the first cooling plate to ensure that there is exactly the same flow resistance, so that the cooling oil flow rate of the first cooling plate and the second cooling plate is the same.

[0015] As a preferred embodiment of the present invention, the first cooling plate, the reaction plate, the second cooling plate and the cover plate are integrally formed by diffusion welding.

[0016] As a preferred embodiment of the present invention, the cover plate is provided with a cooling oil outlet and a reaction liquid outlet.

[0017] The present invention also provides a method for performing a strongly exothermic reaction using the above-mentioned plate microreactor, comprising the following steps:

[0018] 1) The cooling oil is introduced into the first and second cooling plates;

[0019] 2) When the cooling oil flows in the first or second cooling plate, it first passes through the distribution pipes into multiple streams, and then enters the fluid dispersion zone;

[0020] In the fluid dispersion zone, the cooling oil is dispersed through multiple intersecting cooling oil dispersion channels. In the fluid dispersion zone, one stream of cooling oil changes direction after passing through the cooling oil dispersion channel and meets the cooling oil in another cooling oil dispersion channel. When the two streams of cooling oil meet, they form a vortex, thereby breaking the hierarchical structure of the cooling oil.

[0021] 3) After the cooling oil fills the first and second cooling plates and flows out of the cooling plates, the reaction liquid is introduced into the reaction plates;

[0022] 4) When the reaction liquid flows through the micro-reaction chamber, it is first blocked by the impact baffle and divided into two branches, left and right. Then, under the disturbance of the turbulence cylinder, vortexes are generated to enhance mixing. At the end of the micro-reaction chamber, the liquid re-converges into a single fluid, causing collisions and further enhancing the mixing of the fluid.

[0023] 5) The cooling oil in the first and second cooling plates quickly carries away the heat released by the reaction liquid in the reaction plate during the flow process, reducing the occurrence of side reactions and increasing the yield.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. High cooling oil throughput: Through a special high-throughput unit design and the connection design of the unit, it has extremely high cooling oil throughput while ensuring low pressure drop and efficient cooling oil turbulence.

[0026] 2. Low pressure drop: Due to the series-parallel connection design of the cooling oil plates, the flow resistance of the cooling oil circuit is greatly reduced, which reduces the operating cost of the pump while ensuring uniform flow distribution.

[0027] 3. Excellent mixing effect: The reaction liquid channel unit is specially designed, such as setting impact baffles and turbulence cylinders, which can effectively destroy the fluid boundary layer, enhance the fluid turbulence, and thus enhance the mixing effect.

[0028] 4. High heat transfer efficiency: Due to the ultra-high specific surface area of ​​the channel unit and the destruction and regeneration of the heat transfer boundary layer by various microstructures, the convective heat transfer coefficient can be greatly improved, thus enhancing the heat transfer efficiency.

[0029] 5. The design is compact and highly flexible. Through the intermittent design of cooling channel-reaction channel-cooling channel, the number of cooling channels and reaction channels can be flexibly stacked as needed while maintaining a compact volume and reducing the size of the equipment.

[0038] The present invention will be further described and illustrated below with reference to specific embodiments. The embodiments described are merely examples of the content of this disclosure and do not limit the scope of the invention. The technical features of each embodiment in the present invention can be combined accordingly, provided that there is no mutual conflict.

[0039] like Figure 1 As shown, the present invention provides a plate microreactor for a strongly exothermic reaction, comprising a first cooling plate 1, a reaction plate 2, a second cooling plate 3, and a cover plate 4. In a specific embodiment of the present invention, the first cooling plate 1, the reaction plate 2, the second cooling plate 3, and the cover plate 4 are stacked together by diffusion welding.

[0040] The first and second cooling plates have the same structure, both equipped with cooling oil channels for the flow of cooling oil. The cooling oil channels of the first cooling plate are located on the side where the first cooling plate is in contact with the reaction plate, while the cooling oil channels of the second cooling plate are located on the side where the second cooling plate is in contact with the cover plate. Each cooling oil channel includes a distribution pipe, a fluid dispersion zone, and a collection pipe. The distribution pipe is used to distribute the cooling oil into the fluid dispersion zone. The collection pipe is used to collect the cooling oil flowing through the fluid dispersion zone. The fluid dispersion zone is provided with multiple intersecting cooling oil dispersion channels. When the cooling oil enters the fluid dispersion zone, it is dispersed into the fluid dispersion zone through the cooling oil dispersion channels. When a stream of cooling oil changes direction through a cooling oil dispersion channel in the fluid dispersion zone and encounters the cooling oil in another cooling oil dispersion channel, it forms a vortex and breaks up the hierarchical structure of the cooling oil, thereby improving the cooling effect.

[0041] like Figure 6 As shown, multiple rhomboid structures are arranged in an array within the fluid dispersion zone. Adjacent rows of rhomboid structures are staggered and have reserved flow channels for cooling oil. The front end of each rhomboid structure has a "W"-shaped dispersion channel with three ports. After entering from the middle port of the "W"-shaped dispersion channel, the cooling oil changes its flow direction within the "W"-shaped dispersion channel of the rhomboid structure and flows out from the left and right ports of the "W"-shaped dispersion channel. The cooling oil flowing out from the left and right ports meets the cooling oil flowing in the channels between the rhomboid structures, thus forming vortices and merging.

[0042] like Figure 7 As shown, reaction plate 2 is the site where the reaction liquid reacts. A reaction liquid flow channel 13 is provided on the side of reaction plate 2 that is in contact with the second cooling plate 3. The reaction liquid flow channel 13 includes a continuous S-shaped channel and multiple micro-reaction chambers opened on the channel. The micro-reaction chamber is butterfly-shaped and is provided with a flow-blocking baffle 20 and multiple flow-turbulence cylinders 19. The number of flow-turbulence cylinders is even and they are symmetrically arranged on both sides of the flow-blocking baffle.

[0043] like Figure 5 As shown, the cover plate is used to seal the cooling oil flow channels of the second cooling plate.

[0044] The first cooling plate, the reaction plate, and the second cooling plate are all provided with cooling oil inlets at their upper positions, and all of the cooling oil inlets are connected. The cooling oil inlets on the first cooling plate and the second cooling plate are all connected to the front end of their respective cooling oil channels. The reaction plate, the second cooling plate, and the cover plate are provided with cooling oil outlets at their lower positions, and all of the cooling oil outlets are connected. The cooling oil outlet of the reaction plate is connected to the end of the cooling oil channel in the first cooling plate, and the cooling oil outlet of the second cooling plate is connected to the end of the cooling oil channel in the second cooling plate.

[0045] The first cooling plate and the reaction plate have reaction liquid inlet holes at their upper positions, and all of the reaction liquid inlet holes are connected. The reaction liquid inlet holes of the reaction plate are connected to the front end of the reaction liquid flow channel in the reaction plate. The second cooling plate and the cover plate have reaction liquid outlet holes at their lower positions, and all of the reaction liquid outlet holes are connected. The reaction liquid outlet holes of the second cooling plate are connected to the tail end of the reaction liquid flow channel in the reaction plate.

[0046] like Figure 2 As shown, in a specific embodiment of the present invention, the first cooling plate is 155mm long, 127mm wide, and 3mm thick; the first cooling plate 1 is provided with a cooling oil inlet 12, a reaction liquid inlet 11, a cooling oil inlet hole 6, a reaction liquid inlet hole 7, and a cooling oil flow channel; the cooling oil inlet 12 and the reaction liquid inlet 11 are threaded sleeve structures; the cooling oil flow channel is opened on the side of the first cooling plate 1 that is in contact with the reaction plate 2; the depth of the cooling oil flow channel is 2mm; when the cooling oil enters the flow channel in the rhomboid structure, the cooling oil is divided into two branches and changes direction; the cooling oil of each branch changes direction after passing through the flow channel in the rhomboid structure and then meets the cooling oil flowing in the cooling oil flow channel between the rhomboid structures, and the two cooling oils form a vortex and merge after impact; effectively improving the convective heat transfer coefficient;

[0047] like Figure 3As shown, in a specific embodiment of the present invention, the reaction plate 2 is 155mm long, 127mm wide, and 3mm thick; the reaction plate 2 is provided with a cooling oil inlet 6, a reaction liquid flow channel 13, a reaction liquid outlet 10, and a cooling oil outlet 9; the reaction liquid flow channel is opened on the side of the reaction plate that is in contact with the second cooling plate, and the reaction liquid flow channel includes a continuous S-shaped channel and a plurality of micro-reaction chambers opened on the channel; the micro-reaction chamber is butterfly-shaped, and a flow-blocking baffle and a flow-turbulence cylinder are provided in the micro-reaction chamber; when the fluid flows through the micro-reaction chamber, the reaction liquid will first be blocked by the flow-blocking baffle and divided into two branches, left and right, and then generate vortexes to enhance mixing under the disturbance of the flow-turbulence cylinder, and re-gather into a single fluid at the end of the channel, generating collisions, effectively enhancing the mixing and heat transfer of the fluid;

[0048] like Figure 4 As shown, the second cooling plate has a similar structure to the first cooling plate. The second cooling plate is provided with a cooling oil inlet hole, a cooling oil outlet hole 9, a cooling oil channel, and a reaction liquid outlet hole. The cooling oil channel of the second cooling plate has the same structure as that of the first cooling plate to ensure that there is the same flow resistance, so that the cooling oil flow rate of the first cooling plate and the second cooling plate is the same.

[0049] The present invention also provides a method for performing a strongly exothermic reaction using the above-mentioned plate microreactor, comprising the following steps:

[0050] 1) The cooling oil is introduced into the first and second cooling plates;

[0051] 2) Cooling oil first flows into the cooling oil inlet of the first cooling plate, and then splits into two paths after passing through the cooling oil inlet hole of the first cooling plate. One path flows into the distribution pipe through the cooling oil inlet hole of the first cooling plate, then into multiple streams before entering the fluid dispersion zone. After flowing through the fluid dispersion zone, the cooling oil is converged by the manifold pipe and then flows to the cooling oil outlet hole of the reaction plate. The other path flows through the cooling oil inlet hole of the reaction plate, then through the cooling oil inlet hole of the second cooling plate, into the distribution pipe, and then through the fluid dispersion zone and the manifold pipe before flowing to the cooling oil outlet hole of the second cooling plate. The two streams of fluid converge into one at the cooling oil outlet hole of the second cooling plate and flow out together through the cooling oil outlet of the cover plate. After the cooling oil fills the first and second cooling plates and flows out from the cooling plates, the reaction liquid is introduced into the reaction plate.

[0052] In the fluid dispersion zone of the first or second cooling plate, cooling oil is dispersed through multiple intersecting cooling oil dispersion channels. One stream of cooling oil changes direction after passing through a dispersion channel and encounters the oil in another dispersion channel. When the two streams meet, they form a vortex, breaking the hierarchical structure of the cooling oil. Upon reaching the rhomboid structure, the cooling oil is divided into three streams. One stream flows in from the middle port of the "W"-shaped dispersion channel within the rhomboid structure, while the other two streams flow from either side. After entering from the middle port of the "W"-shaped dispersion channel, the cooling oil changes direction within the channel and exits from the left and right ports, encountering the other two streams and forming vortices, further breaking the hierarchical structure of the cooling oil. The vortices then merge, and the merged cooling oil flows to the next rhomboid structure.

[0053] 4) The reaction liquid first flows in from the reaction liquid inlet of the first cooling plate, passes through the reaction liquid inlet hole of the first cooling plate and the reaction liquid inlet hole of the reaction plate in sequence, and then reacts in the reaction liquid channel of the reaction plate. After the reaction is completed, it flows through the reaction liquid outlet hole of the second cooling plate and flows out from the reaction liquid outlet.

[0054] When the reaction liquid flows through the micro-reaction chamber, it is first blocked by the impact baffle and divided into two branches, left and right. Then, under the disturbance of the turbulence cylinder, vortexes are generated to enhance mixing. At the end of the micro-reaction chamber, the liquid re-converges into a single fluid, causing collisions and further enhancing the mixing of the fluid.

[0055] 5) The cooling oil in the first and second cooling plates quickly carries away the heat released by the reaction liquid in the reaction plate during the flow process, reducing the occurrence of side reactions and increasing the yield.

[0056] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
