The microreactor is a microreactor which is manufactured at least partially by using a micro-reaction technology or an ultra-precision machining technology, and the characteristic dimension of an internal structure (such as a flow channel) of the microreactor is generally between submicron and millimeter.

The micro-reactor in the broad sense is a micro-reaction system which takes the main purpose of reflection, mainly comprises one or more micro-reactors, and also can comprise auxiliary devices such as micro-mixing, heat exchange, separation, extraction and the like, and key components such as micro-sensors, micro-actuators and the like.

The microreactors of the present disclosure may be any of the above.

In addition, the materials, media, etc. referred to in this disclosure are all materials that participate in the mixing/reaction and may be fluids.

The reaction medium/material of the microreactors provided by the present disclosure may be gaseous, liquid or dispersed for physical or chemical reaction of reactants within the channel.

As described in the background art, the current mainstream microchannel structure mainly uses a planar two-dimensional structure, and is simply stretched in a planar manner in a third direction, so that a flow interface is difficult to be damaged in the third direction, and the effect of convection is relied on, and a pressure drop caused by strong convection also causes a burden to the operation of equipment.

The first embodiment is as follows: as shown in fig. 1, firstly, a three-dimensional micro-channel structure is provided, an extension path of the channel structure is expanded into a three-dimensional space, and is not only simply stretched in a plane, but also stretched in a three-dimensional layer, so that a flow interface can be effectively damaged in a third direction, a large amount of secondary flows can be generated in a flow process, mixing is promoted, and a good mass and heat transfer effect is realized while pressure drop is effectively reduced.

A three-dimensional continuous flow micro-reaction channel comprises an input section (in the embodiment, A in FIG. 1), a reaction section and an output section which are connected in sequence, wherein the input section comprises at least two inlets for inputting reaction media and corresponding transmission channels, and the output section comprises at least one transmission channel for mixing and an outlet for outputting mixed media;

the reaction section comprises a plurality of reaction units, each reaction unit comprises a first part (in the embodiment, B, D, F shown in FIG. 1) for mixing the fluid, a second part (in the embodiment, C, E shown in FIG. 1) for dividing the fluid into at least two paths, and the first part and the second part are connected and positioned in the same plane;

As shown in fig. 2, the flow regions and mixing mechanisms of the three-dimensional channels are ideally the following main flow modes:

the materials enter from two inlets of the area A respectively, form upper and lower layers in the area B, are separated in the area C through a bifurcation structure, and form a double-channel upper and lower layered state. And C, superposing the double-channel fluid up and down in the D area to form a four-layer fluid layering state. And (3) continuing to form branches at the position E, merging at the position F, and repeating in such a way, so that infinite layering of the fluid can be realized theoretically, and finally, a strong mixing effect is achieved.

In practical cases, due to the presence of interfacial tension, although it is difficult to completely achieve the described ideal layered state, a large amount of secondary flow can be generated in the flow due to the distortion of the spatial structure, thereby promoting mixing.

In the first embodiment, the fluid region shown in fig. 1 is only a single row of channels, and in practical applications, the channels may be densely distributed on the channel plate in a continuous series manner or in a grouped parallel manner.

That is, in other embodiments, the general extending direction of the reaction channel may not be a straight line, but a curve, such as S-shape, zigzag, etc., or a spiral in space, which is not described herein again.

For example, in the fourth embodiment, as shown in FIG. 9, a reaction channel is provided that is generally "R" shaped, with at least one leg in the second portion being S-shaped, having a more serpentine channel than n-shaped, to facilitate mixing. On the other hand, the pressure drop is properly reduced, the channel mainly adopts plug flow, the back mixing condition can be greatly reduced, and meanwhile, the reaction with strict dead zone requirements is also very suitable, and the relative processing process is more complex.
