Chip type micro reaction channel and micro reactor

Abstract

The invention discloses a chip type micro reaction channel and a micro reactor. The chip type micro reaction channel comprises a substrate and a chip, wherein the chip is positioned on the substrate and comprises a diversion structure and a first fluid part and a second fluid part which are partitioned by the diversion structure; the first fluid part comprises a first inlet; the second fluid part comprises a second inlet; meanwhile the first fluid part is partitioned into at least first diversion channels by the diversion structure; the second fluid part is partitioned into at least two second diversion channels by the diversion structure; moreover mixing channels are formed in a connected manner in corresponding positions of the first diversion channels and the second diversion channels on the substrate; the mixing channels are respectively connected with the first diversion channels and the second diversion channels. The micro reactor comprises a first chip type micro reaction channel. By adopting the chip type micro reaction channel and the micro reactor, different reactants in two types of fluid can be sufficiently mixed and reacted, the reaction speed can be increased, the reactant generation efficiency can be improved, and meanwhile the reaction security and reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a chip-type micro-reaction channel and a micro-reactor. Background technique [0002] 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 residence time of reactants. These characteristics enable the precise control of organic synthesis reactions at the microscopic scale, which provides the possibility to improve reaction selectivity and operational safety. [0003] Most of the micror...

AI Technical Summary

Problems solved by technology

[0003] Most of the currently used microreactors have a simple reaction channel structure, and their mixing effect is average, and the reaction cannot be fully mixed, so the yield of the reaction product is not high.
