It is only suitable for pipes with larger diameters, and cannot be used for thinner pipes or the mixing effect is poor. It is biased towards the petrochemical industry and has a high cost. Summary of the invention

[0004] In view of this, the present invention proposes a honeycomb type insert, wherein the honeycomb type insert comprises a cylindrical insert body, and the insert body is a cylindrical foam metal.

[0005] Based on the above solution, the foam metal is foam metal aluminum, foam metal titanium, foam metal copper or foam metal nickel.

[0006] Based on the above solution, the porosity of the foam metal is 20-40%.

[0007] Based on the above solution, the insert body is provided with a plurality of cavities for fixing the catalyst.

[0008] On the basis of the above scheme, the cylindrical foam metal is processed in the following manner:

[0009] The foam metal sheet is cut into foam metal strips by laser cutting; thereafter, the foam metal is polished or laser cut multiple times to form a long cylindrical foam metal.

[0010] On the basis of the above scheme, the cylindrical foam metal is processed in the following manner:

[0011] A foam metal block is made into a short foam metal column by grinding or multiple laser cutting, and then a plurality of short foam metal columns are welded into a long foam metal column, or a plurality of short foam metal columns are directly inserted into a matching pipe, and the pipe constrains the plurality of short foam metal columns into a long foam metal column.

[0013] The present application also provides a reaction tube, which comprises an outer tube and an inner plug-in arranged in the outer tube, and the inner plug-in is the above-mentioned honeycomb inner plug-in.

[0014] The honeycomb insert of the present application is based on the existing foam metal material. The internal structure of the foam metal is intricate and similar to the honeycomb structure, which can fully mix the fluid. At the same time, the honeycomb main structure can realize the immobilization of the catalyst, which can not only achieve the mixing of materials, but also realize the reaction that needs to be catalyzed.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] Example 1

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the present application provides a honeycomb type insert, the insert comprises a cylindrical insert body 1, and the insert body 1 is a cylindrical foam metal.

[0024] Foam metal refers to a special metal material containing foam pores. Through its unique structural characteristics, foam metal has a series of good advantages such as low density, good heat insulation, good sound insulation and the ability to absorb electromagnetic waves. It is often used in a series of industrial developments such as aerospace, petrochemicals, etc.

[0025] As a specific embodiment, the foam metal is foam metal aluminum, foam metal titanium, foam metal copper or foam metal nickel.

[0026] As an inner plug-in for a mixer, the porosity of the foam metal should be moderate. As a preferred embodiment, the porosity of the foam metal is 20-40%.

[0027] Example 2

[0028] At present, the insert in Example 1 cannot be directly made into a cylindrical strip like a foam metal plate or a foam metal block. Therefore, if the insert in Example 1 is to be produced, the following method is required:

[0029] Method 1:

[0030] Use laser cutting to cut the foam metal plate (rectangular plate, Figure 4 As shown in a) in the figure, the foam metal strips (cutting along the position shown by the dotted line) are cut into the foam metal strips (rectangular strips, Figure 4 After that, it is polished or laser cut multiple times to form a long cylindrical foam metal (as shown in Fig. Figure 4 As shown in c, grind or cut off the part outside the dotted line); finally get Figure 1 The structure in .

[0031] The insert obtained by the method in method 1 has good integrity, but is relatively complicated to process. In order to broaden the processing methods, the present application provides another processing method.

[0032] Method 2:

[0033] A foam metal block is made into a short foam metal column by grinding or multiple laser cutting, and then a plurality of short foam metal columns are welded into a long foam metal column, or a plurality of short foam metal columns are directly inserted into a suitable pipe to form a mixer or a reaction tube.

[0034] Example 3

[0035] When the inner plug is used simply as a mixer, the inner plug does not need to be loaded with a catalyst. However, when it is used as a reaction tube for a continuous flow reactor, the catalyst needs to be loaded on the honeycomb inner plug due to the reaction requirements. For this purpose, based on the inner plug in Example 1 or the inner plug prepared in Example 2, as shown in FIG. Figure 4As shown, a plurality of cavities 1 - 1 for fixing the catalyst 3 are arranged on the inner plug body 1 .

[0036] Example 4

[0037] like Figure 5 As shown, based on the inner plug-in in Example 1 or the inner plug-in prepared in Example 2, the present application provides a mixer, which includes an outer pipe 2 and a honeycomb inner plug-in arranged in the outer pipe 2.

[0038] Example 5

[0039] like Figure 5 As shown, based on the inner plug-in in Example 1 or the inner plug-in prepared in Example 2 or the honeycomb inner plug-in capable of loading a catalyst in Example 3, the present application provides a reaction tube comprising an outer pipe 2 and an inner plug-in disposed in the outer pipe 2.

[0040] The above reaction tube can be used in a flowing continuous flow reactor. A plurality of reaction tubes are connected in parallel and / or in series in the reactor.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments 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.
