Embodiment 1

[0029] This embodiment discloses a microreactor, such as figure 1 As shown, it includes an outer tube 19, a reaction tube 9 and an inner tube 3 that are set in sequence from the outside to the inside, wherein the inner tube 3 has Karman vortex street generating parts 4 arranged at intervals along its length direction, and the mixing tube 18 passes through the outer tube 3. The tube 19 is communicated with the reaction tube 9; and the position where the mixing tube 18 is connected to the reaction tube 9 is located between the two Karman vortex street generation parts 4, and is close to the previous Karman vortex street generation part 4; the material A flows through the reaction tube 9 and the space between the inner pipe 3, the material B enters the space between the reaction pipe 9 and the inner pipe 3 through the mixing pipe 18, and is mixed with the material A. The working principle and advantages of the present invention are that: the material A flows through the space bet...

Embodiment 2

[0033] This embodiment discloses a microreactor, such as Image 6 As shown, the reaction tube 9 is a microporous membrane tube, and the microporous membrane tube is formed with tubular microporous portions 20 communicating with the inner space of the reaction tube 9 at intervals along its length direction. Between the generation parts 4, the material A flows between the reaction tube 9 and the inner tube 3, the material B flows between the outer tube 19 and the reaction tube 9, and the material B enters the reaction tube 9 through the tubular microporous part 20 and is connected with the reaction tube 9. The materials A forming the Karman vortex street phenomenon are mixed, the cooling medium A flows through the inside of the inner tube 3 , and the cooling medium B flows through the outside of the outer tube 19 . The advantage of this embodiment is that: the tubular microporous portion 20 plays a dispersing role, which further strengthens the mixing; the material B enters in t...

Embodiment 3

[0036] This embodiment discloses a parallel high-efficiency microreactor, such as Figure 2-5 As shown, it includes a plurality of inner tubes 3 and a plurality of reaction tubes 9 respectively sleeved outside the plurality of inner tubes 3 . Among them, a plurality of reaction tubes 9 are built in the reactor shell 1 , the cooling medium flows through the inner tubes 3 and the reactor shell 1 respectively, and the material A enters each of the first material tubes 10 through the plurality of branch pipes 11 In the space between the reaction tubes 9 and the corresponding inner tubes 3 , the material B enters the space between the reaction tubes 9 and the corresponding inner tubes 3 through the second material tube 15 . The working principle and advantages of the present invention are: the present invention is a parallel micro-reactor formed based on the above-mentioned micro-reactor, and the difference lies in that the outer tube 19 of the above-mentioned micro-reactor is replac...

Abstract

The invention discloses a micro-reactor and a parallel high-efficiency micro-reactor, both of which have an inner tube configured as a tubular structure with a Karman vortex street generating part, and a Karman vortex street phenomenon occurs after material A passes through the Karman vortex street generating part, Then inject the material B into this position, under the action of the Karman vortex street, the mixing reaction of the two materials is sufficiently uniform. On the premise that the two materials are fully mixed, the present invention improves the mixing reaction efficiency, thereby improving the production efficiency. The present invention is applicable to the technical field of two-phase mixed reaction.

Description

technical field [0001] The invention relates to a micro-reactor, a parallel high-efficiency micro-reactor and its application. Background technique [0002] Microreactor, that is, microchannel reactor, is a three-dimensional structural element that can be used to carry out chemical reaction manufactured by means of special microfabrication technology in solid substrate. Microreactor usually contains small channel size and channel diversity. flow in these channels and require the desired reactions to take place in these channels. This results in very large surface area / volume ratios in microstructured chemical devices, which can contain millions of microchannels in microreactors, and thus also achieve high yields. [0003] Microreactors have completely different characteristics from macroreactors: narrow and regular microchannels, very small reaction spaces and very large specific surface areas. Its geometric characteristics determine the transfer characteristics and macros...
