First embodiment
This embodiment provides a relatively moving annular gap microreactor 100, as shown in FIG. 1, comprising an inner cylindrical body 110, an outer housing 120, and a driving means (not shown).
As shown in fig. 1, the outer casing 120 is sleeved outside the inner cylinder 110, and a micro-reaction gap 130 is formed between the inner cylinder 110 and the outer casing 120. The outer housing 120 is fixed, and the inner cylinder 110 is driven by the driving device to rotate around the axis thereof.
Further, the width of the micro-reaction gap 130 is 0.1 to 10 mm. The raw material entering the micro-reaction gap 130 forms a fluid film under the relative motion of the inner cylinder 110 and the outer shell 120, so that the raw material is fully dispersed, and the reaction process of the raw material is more efficient and stable. Especially for solid raw materials and non-Newtonian fluids, the method can well avoid the coagulation of the raw materials and reduce the resistance pressure drop of the raw material conveying process.
As shown in fig. 1, the outer casing 120 includes a sidewall 121 disposed along a length direction thereof, a radial feed port 122 and a radial discharge port 123 are respectively disposed at two ends of the sidewall 121 in the length direction, and the radial feed port 122 and the radial discharge port 123 penetrate through the sidewall 121 and communicate with the micro-reaction gap 130. The raw material enters the micro-reaction gap 130 through the radial feed inlet 122, and is discharged through the radial discharge outlet 123 at the other end after the reaction is completed. The raw material moves from the radial inlet 122 to the radial outlet 123, i.e. the raw material is chemically reacted.
Optionally, the number of the radial feed openings 122 is multiple, and the multiple radial feed openings 122 are arranged at intervals along the length direction of the outer shell 120. In reactions involving multiple feedstocks, the feedstocks may be added through different radial feed ports 122 to control the timing of the reactions involving the different feedstocks. For example, the plurality of radial feed ports 122 are sequentially denoted as a first feed port, a second feed port, a third feed port, and the like from large to small according to the distance between the radial feed ports and the radial discharge port 123. When the raw material A entering from the first feeding hole moves to the second feeding hole, the raw material A and the raw material B entering from the second feeding hole are mixed and reacted, and the raw material A and the raw material B move together to the third feeding hole and then are mixed and reacted with the raw material C. In the process of reaching the third feeding port, the raw material A and the raw material B actually react for a period of time, so that the effect similar to that of stepwise feeding in an organic reaction is achieved.
Besides, the number of the radial discharge ports 123 is plural, and the plural radial discharge ports 123 are arranged at intervals along the length direction of the outer housing 120. The further the radial feed outlet 123 is from the radial feed inlet 122 means that the longer the feedstock is reacted in the micro-reaction gap 130. The design of the plurality of radial discharge holes 123 can be used for collecting products in different reaction time periods, and is used for judging the reaction conditions of raw materials, so that effective conditions are provided for optimization of a chemical process.
As shown in fig. 1, for some reactions requiring heating, a heating plate 124 may be provided on the inner surface of the outer housing 120 and/or the outer surface of the inner cylinder 110. In this embodiment, it is easier to dispose the heating plate 124 on the inner surface of the outer housing 120, because the outer housing 120 is fixedly disposed, and the wiring of the heating plate 124 is simpler. The heating plate 124 is circumferentially disposed around the inner cylinder 110 to provide more uniform heating of the feedstock within the micro-reaction gap 130. Further, the number of the heating plates 124 is plural, and the plural heating plates 124 are arranged at intervals in the axial direction of the inner cylinder 110. The plurality of heater plates 124 may be controlled by different transformers, and different voltages may be applied to the plurality of heater plates 124, respectively, to generate different temperatures in the plurality of heater plates 124. In general, the temperature may be gradually increased from the radial inlet 122 to the radial outlet 123, so as to achieve the effect of gradient temperature increase and avoid by-products caused by too fast temperature increase.
In addition, the outer surface of the inner cylinder 110 may be provided with anti-slip patterns (not shown), and specifically, the anti-slip patterns may be formed by a plurality of ribs, each of which extends from one end to the other end along the length direction of the inner cylinder 110.

As shown in fig. 2, for some reactions requiring heating, a heating plate 211 may be provided on the inner surface of the outer housing 220 and/or the outer surface of the inner cylinder 210. In this embodiment, it is simpler to dispose the heating plate 211 on the outer surface of the inner cylinder 210, because the inner cylinder 210 is fixedly disposed, it is simpler for the connection of the heating plate 211. The heating plates 211 are circumferentially disposed along the inner cylinder 210 to provide more uniform heating of the material in the micro-reaction gap 230. Further, the number of the heating plates 211 is plural, and the plural heating plates 211 are arranged at intervals in the axial direction of the inner cylinder 210. The plurality of heating plates 211 may be controlled by different transformers, and different temperatures may be generated in the plurality of heating plates 211 by setting different voltages to the plurality of heating plates 211. In general, the temperature may be gradually increased from the axial inlet 222 to the axial outlet 223, so as to achieve the effect of gradient temperature increase and avoid by-products caused by too fast temperature increase.
In addition, the inner surface of the outer casing 220 may be provided with anti-slip threads (not shown), and specifically, the anti-slip threads may be formed by a plurality of ribs, each of which extends from one end to the other end of the outer casing 220 along the length direction thereof.

To increase the friction between the outer shell 220 and the material so that the material can be spread more uniformly.
Further, on the basis of the annular gap microreactor 200 of the present embodiment, the outer casing 220 and the inner cylinder 210 can be adapted to rotate in opposite directions around the axis thereof under the driving of the driving device. Due to the power limitations of the drive, to increase the speed of the outer housing 220 and the inner cylinder 210 singly, the drive requirements will be higher and higher, and the cost will increase in geometric multiples. However, if the outer casing 220 and the inner cylinder 210 rotate in opposite directions, the relative speed of the two is the sum of the absolute speeds, so that the requirement on the equipment can be reduced while the requirement on the rotating speed is met.
In summary, the embodiment of the present invention provides an annular gap microreactor with relative motion, which includes an inner cylindrical body, an outer casing, and a driving device, wherein the outer casing is sleeved outside the inner cylindrical body, and a micro-reaction gap is formed between the inner cylindrical body and the outer casing.
