Flow dividing opposite impact microreaction passage and microreactor

Abstract

The invention relates to a flow dividing opposite impact microreaction passage and a microreactor. The flow dividing opposite impact microreaction passage comprises a reaction body, wherein one end of the reaction body is provided with a first inlet; the other end of the reaction body is provided with a second inlet; the reaction body is also provided with a fluid outlet positioned between the first inlet and the second inlet; a first fluid section is arranged between the first inlet and the outlet; a second fluid section is arranged between the second inlet and the outlet; a flow dividing structure for performing flow dividing on fluid is also arranged in the first fluid section and / or the second fluid section; the first fluid section and / or the second fluid section are / is separated into at least two flow dividing passages through which reaction fluid is allowed to pass by the flow dividing structure; the reaction body also comprises a mixing region which is positioned between the first fluid section and the second fluid section and communicates with the outlet; the mixing region is used for mixing the fluid of the first fluid section and the second fluid section. The microreactor comprises the flow dividing opposite impact microreaction passage. Two kinds of fluid can realize full mixed reaction; the reaction speed is accelerated; the reactant generation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a diversion-hedging 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 huge surface area and high 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.

AI Technical Summary

Problems solved by technology

[0003] Most of the microreactors currently used have a simple reaction channel structure. Due to their general mixing effect, they cannot fully mix the reaction, so the yield of the reaction product is not high.
