Description

Technical Field

[0001] The utility model relates to the technical field of chemical pharmaceutical equipment, in particular to an industrial-grade continuous flow reaction matrix. Background Art

[0002] Tubular reactors are currently a commonly used reactor equipment in the field of chemical and pharmaceutical technology, and the application of single tubular reactors in chemical synthesis reactions is increasingly recognized. However, the flow rate of continuous flow tubular reactors is relatively small and cannot adapt to the reaction requirements of large flow rates. When performing catalytic reactions in traditional tubular reactors, the catalyst is usually arranged in the tube head of the reactor. This method can meet the needs of catalytic reactions to a certain extent. However, the contact time between the catalyst arranged in the tube head and the reaction fluid is limited. If the catalytic reaction can be continuously carried out in the reaction tube, the requirements of industrial production can be greatly met.

[0003] At the same time, some reactions require photocatalysis or photocatalysis + catalyst catalysis, and traditional tubular reactors are difficult to meet the requirements. Utility Model Content

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] Example 1

[0027] like Figure 1-4 As shown, the present application provides an industrial-grade continuous flow reaction matrix, comprising an outer shell 1, a support frame 2 and a reactor module 3; the reactor module 3 comprises at least two reactors 3-1, a shell-side pipeline 4 for simultaneously providing heat exchange fluid to the shell side of the reactor 3-1 in the reactor module 3, a feed pipeline 5 for inputting reaction fluid into the reactor 3-1 of the reactor module 3, and a discharge pipeline 6 for outputting the post-reaction fluid in the reactor 3-1 of the reactor module 3.

[0028] The reactors 3 - 1 in the reactor module 3 are connected in series or in parallel. Figure 3 The diagram shows a 2×4 reaction matrix, in which two reactors 3-1 are connected in series to form a continuous flow reaction channel, and four such reaction channels are connected in parallel to form a reaction matrix. This reaction matrix can be adjusted according to different production requirements, for example, reducing the number of reaction channels from four to one to three.

[0029] As a specific embodiment, the connection between the discharge pipeline 6 and the reactor 3-1 directly connected thereto is provided with a sampling valve 6-1 for sampling from the fluid flowing out of the reactor 3-1, a pipeline pressure sensor 6-2 for monitoring the pressure of the fluid flowing out of the reactor 3-1, and a ball valve 6-3 for controlling the flow of fluid between the reactor and the discharge pipeline 6.

[0030] from Figure 3 It can be seen that a sampling valve 6-1 is provided at the outlet of the last reactor 3-1 on each reaction channel. In this way, the progress of the reaction in each reaction channel can be monitored at any time to achieve accurate monitoring. At the same time, a ball valve 6-3 is provided on each reaction channel and the discharge pipeline 6, so that each reaction channel can be flexibly controlled.

[0031] As a specific implementation scheme, the discharge pipeline 6 is further provided with a back pressure valve 6 - 4 , so as to realize the control of the entire reaction matrix.

[0032] For industrial synthetic reaction production, consistent reaction temperature conditions are very important. To this end, based on the above technical solution, the shell-side pipeline 4 includes an input pipe 4-1 for simultaneously inputting heat exchange fluid to the reactor 3-1 in the reactor module 3 and an output pipe 4-2 for simultaneously receiving the heat exchange fluid refluxed from the reactor 3-1 in the reactor module 3.

[0033] Temperature and pressure during chemical synthesis reactions are crucial for safe production. Therefore, the reactor 3-1 is equipped with a pressure sensor 3-2 for monitoring the pressure of the reaction fluid within the reactor 3-1 and a temperature sensor 3-3 for monitoring the temperature of the reaction fluid within the reactor 3-1. The pressure sensor 3-2 and the temperature sensor 3-3 allow for real-time monitoring of the reaction conditions in each reactor.

[0034] The lengths of the channels for fluid reaction in the reactors 3 - 1 used in the industrial-grade continuous flow reaction matrix in this application are all the same.

[0035] In this embodiment, the reaction tube 3 - 4 in the reactor 3 - 1 of the reaction matrix can be a straight tube or a spiral tube. Figure 3 The spiral tube style is shown in FIG.

[0036] like Figure 8 and Figure 9 As shown, when the reaction tube 3-4 in the reactor 3-1 is a straight tube, a spoiler plate 3-41 is provided in the reaction tube 3-4 for disturbing the reaction fluid flowing in the reaction tube 3-4.

[0037] like Figure 5 、 Figure 6 and Figure 7 As shown, the spoiler plate 3-41 is provided with a plurality of through holes 3-43 for fixing the catalyst 3-42 and / or for disturbing the reaction fluid in the reaction tube 3-4.

[0038] This configuration of the spoiler plate has multiple uses. In reactions that do not require catalysis, the catalyst 3-42 does not need to be fixed in the through-hole 3-43 on the spoiler plate 3-41. In this case, the through-hole 3-43 can serve as a channel for fluid circulation, effectively increasing the flow disturbance effect. When a catalyst is required for a reaction, the catalyst can be fixed in the through-hole 3-43, and then the spoiler plate 3-41 with the catalyst fixed thereon can be inserted into the reaction tube. Under the premise that the spoiler plate 3-41 plays a role in flow disturbance, the catalyst required for the catalytic reaction can be met.

[0039] When in use, the amount of catalyst 3-42 can be set according to the amount of catalyst required for the chemical reaction. The catalyst can be set in a part of the through holes 3-43 while the remaining through holes 3-43 play the function of disturbing the flow.

[0040] In order to improve the spoiler effect of the spoiler, the spoiler 3-41 is spiral in shape as a whole.

[0041] like Figure 9 As shown, the reaction tube 3-4 is a glass tube, and the reactor 3-1 is further provided with a plurality of light source tubes 3-5 for providing light sources for the photocatalytic reaction. The light source tubes 3-5 are also glass tubes.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
