Embodiment 1

[0038] like figure 1As shown, the present invention provides a column row microreaction channel, which includes a microreaction unit 1, and the microreaction unit includes an inlet section 11, an outlet section 12 and an expansion section 13 between the two, wherein the expansion section 13, the flow cross-sectional area perpendicular to the fluid flow direction is respectively larger than the flow cross-sectional area of ​​the inlet section 11 and the outlet section 12; and a flow area first formed between the inlet section 11 and the expansion section 13 The first curved part 14 is reduced and then enlarged, and at least one first splitter column 2 is arranged at the first curved part 14 .

[0039] In the micro-reaction channel of the column row of the present invention, a first bend portion in which the flow area first decreases and then increases is formed between the inlet section and the expansion section, and in the first bend portion At least one first splitter column...

Embodiment 2

[0045] like figure 2 As shown, on the basis of Example 1, preferably, the column-row micro-reaction channel of the present invention can also be set as a reversible mixed reaction channel, that is, a communication channel is also formed between the outlet section 12 and the expansion section 13 The area of ​​the second bend portion 15 first decreases and then increases, and a plurality of rows of second splitter columns 5 arranged along the fluid flow direction are arranged at the second bend portion 15 .

[0046] Since the fluid flow in the micro-reaction unit of Example 1 has a certain directionality, it is suitable for occasions where the flow direction is single, clear and clearly distinguishable. Once the fluid flows backward, the mixing effect will be greatly reduced. Therefore, for occasions where the flow direction is uncertain or reverse flow is required, a reversible mixing structure is required. The present invention proposes a reversible mixing structure, the flo...

Embodiment 3

[0050] like image 3 Shown, on the basis of embodiment 1 or 2, preferably, the micro-reaction channel of the present invention also comprises " mouth " shape channel, and described " mouth " shape channel comprises inlet pipeline 6, outlet pipeline 7 and is located at two The two branch flow pipelines 8 between them, the two branch flow pipelines divide the fluid into two at the joints with the inlet pipelines, and the two branch flow pipelines and the outlet pipelines The junction combines the two fluids into one;

[0051] The micro-reaction unit is formed in the inlet pipeline 6 and / or the outlet pipeline 7 and / or at least one part of the distribution pipeline 8 .

[0052] By also including a "port"-shaped channel, and the micro-reaction unit is formed in the inlet pipeline, and / or the outlet pipeline, and / or at least one part of the split pipeline, can pass through " The “mouth”-shaped channel plays the role of diverting the fluid and converging again, increasing the suff...

Abstract

The invention provides a column array micro reaction channel and a micro reactor. The column array micro reaction channel comprises a micro reaction unit (1). The micro reaction unit comprises an inlet section (11), an outlet section (12) and an expansion section (13) between the inlet section (11) and the outlet section (12). A first bend portion (14) is formed between the inlet section (11) and the expansion section (13), and the flow area of the first bend portion (14) firstly decreases and then increases. At least one first flow distribution column (2) is arranged at the first bend portion (14). The column array micro reaction channel has the advantages that flow speeds of fluids can be increased at the first bend portion; when the high-speed fluids impact on the first flow distribution columns, transverse flow speeds and turbulence degrees of the fluids as well as mixing sufficiency degree among the fluids can be increased, and accordingly, reaction yield of the micro reaction channel is increased effectively.

Description

technical field [0001] The invention belongs to the technical fields of chemical engineering and medical machinery, and in particular relates to a column row micro-reaction channel and a micro-reactor. Background technique [0002] In the process of chemical or pharmaceutical production, the reaction work between fluids is mostly realized by the mixing of microreactors, and the mixing of two fluids is the most common work of microreactors. Microreactor is a micropipeline reactor based on continuous flow, which is used to replace traditional batch reactors such as glass flasks, funnels, and reactors commonly used in industrial organic synthesis. In the microreactor, there are a large number of micro reaction channels made with precision processing technology, which can provide a large specific surface area and high mass and heat transfer efficiency. In addition, microreactors use continuous flow instead of intermittent operation, making it possible to accurately control the ...
