Description

Technical Field

[0001] The utility model relates to the technical field of chemical pharmaceutical equipment, and particularly relates to a spoiler plate, a reaction tube and a reactor. Background Art

[0002] The tubular reactor is a commonly used pharmaceutical equipment in the technical field of chemical pharmacy, especially for reactions with high purity and precision requirements. When the material reacts in the reaction tube, it is necessary to increase the turbulence of the liquid in the reaction tube to make it fully mixed. There are various types of internal inserts used in existing reactors, but they cannot fully meet the diverse needs of chemical reactions. For example, for some reactions that require the use of catalysts, the traditional method is to set a cavity for placing the catalyst at the tube head of the reactor, which can solve certain practical needs to a certain extent. During the reaction process, this way of setting the catalyst results in a short contact time between the catalyst and the reaction fluid. At the same time, for some reactions that require photocatalytic reaction or photocatalysis + catalyst catalysis, it is difficult for traditional tubular reactors to meet the requirements.

[0017] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects according to the present utility model as follows.

[0018] As Figure 1 and 2 shown, the present application provides a specific embodiment of a spoiler sheet. The spoiler sheet includes a spoiler sheet body 1, and a plurality of through holes 1-1 for fixing the catalyst 2 and / or for disturbing the reaction fluid in the reaction tube are provided on the spoiler sheet body 1.

[0019] Such a spoiler sheet has multiple uses. In a reaction that does not require catalyst catalysis, the through holes 1-1 on the spoiler sheet body 1 do not need to fix the catalyst 2. At this time, the through holes 1-1 can be used as fluid flow channels, effectively increasing the turbulence effect. When the reaction requires a catalyst, the catalyst can be fixed in the through holes 1-1, and then the spoiler sheet with the fixed catalyst is inserted into the reaction tube. On the premise that the spoiler sheet plays a role in disturbing the flow, it can meet the catalyst required for the catalytic reaction.

[0020] During use, the amount of catalyst 2 can be set according to the amount of catalyst required for the chemical reaction. Catalyst can be provided in some of the through holes 1-1, while the remaining through holes 1-1 function as flow spoilers.

[0021] To improve the flow spoiling effect of the flow spoiler sheet, the entire body 1 of the flow spoiler sheet is helical.

[0022] Based on the flow spoiler sheet of Embodiment 1, the present application provides a specific embodiment of a reaction tube, as Figure 3 shown. The reaction tube includes a reaction tube body 3, and the flow spoiler sheet in Embodiment 1 is disposed inside the reaction tube body 3.

[0023] This reaction tube can not only meet ordinary chemical reactions, but also meet chemical reactions that require a catalyst. During use, it is only necessary to set whether to place a catalyst in the through holes 1-1 on the body 1 of the flow spoiler sheet according to the actual situation.

[0024] Based on the flow spoiler sheet of Embodiment 1 and the reaction tube of Embodiment 2, the present application provides a specific embodiment of a reactor, as Figure 4 and 5 shown. The reactor includes a reactor housing 4 and a plurality of reaction tubes disposed inside the reactor housing 4; the reaction tubes are the reaction tubes of Embodiment 2 or the reaction tube bodies 3 of the reaction tubes are provided with the flow spoiler sheets of Embodiment 1.

[0025] During use, a flowing circulating fluid is introduced between the reactor housing 4 and the reaction tubes to provide a suitable reaction temperature for the reaction. A reaction fluid is introduced into the reaction tubes.

[0026] To meet the requirements of photocatalytic reactions, based on the above embodiments, as Figure 5 and Figure 6 shown, the reaction tube body 3 is a glass tube; a plurality of light source tubes 5 for providing a light source for photocatalytic reactions are further disposed inside the reactor housing 4. The light source tubes 5 are also glass tubes, and a light source lamp strip 5-1 is disposed inside the light source tubes 5.

[0027] This reactor of the present application can meet various different reaction requirements through different combinations of the light source tubes 5, the flow spoiler sheets, and the catalyst 2.

[0028] Several reaction tubes in the reactor can be set in a parallel connection mode according to actual reaction requirements (i.e., the reaction fluid flowing into the reactor simultaneously flows into all reaction tubes from one end, and then simultaneously flows out from the other ends of each reaction tube and converges and flows out of the reactor), or in a series mode (i.e., the reaction fluid flowing into the reactor flows into one end of a reaction tube, then sequentially flows through other reaction tubes, and finally flows out from one end of the last reaction tube and finally flows out of the reactor, and this series mode can be used). In addition to the parallel and series modes, a special baffle tube box can also be used to achieve the mode of simultaneously setting parallel and series in one reactor. The baffle tube box uses Patent 201720675234.5 (series), 201920288673.X (series + parallel), and baffle tube boxes in other patents of the Chinese patent applicant: Shandong NuoWei Pharmaceutical Fluid System Co., Ltd. can also be used, which will not be elaborated here.

[0029] As described above, it is only a preferred embodiment of the present utility model, and it does not impose any formal restrictions on the present utility model. Although the present utility model has been disclosed above with a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
