Abstract

The invention discloses a micro-reactor and a parallel efficient micro-reactor, an inner tube is constructed into a tubular structure with a Karman vortex street generating part, a material A generates a Karman vortex street phenomenon after passing through the Karman vortex street generating part, then a material B is injected into the position, and the two materials are mixed and reacted fully and uniformly under the effect of the Karman vortex street. On the premise that two materials are fully mixed, the mixing reaction efficiency is improved, and the production efficiency is further improved. The invention is suitable for the technical field of two-phase mixing reaction.

Description

technical field [0001] The invention relates to a microreactor, a parallel high-efficiency microreactor and applications thereof. Background technique [0002] A microreactor, namely a microchannel reactor, is a three-dimensional structural element that can be used for chemical reactions made of a solid matrix by means of special micromachining techniques. Microreactors usually contain small channel sizes and channel diversity. Fluids in These channels flow and require the desired reactions to take place in these channels. This leads to very large surface area / volume ratios in microstructured chemical devices, and microreactors can contain millions of microchannels and thus achieve high throughput. [0003] Microreactors have completely different characteristics from large reactors: narrow and regular microchannels, very small reaction space and very large specific surface area. Its geometric characteristics determine the transfer characteristics and macroscopic flow chara...
