Micro-mixing chip and micro-channel reaction system

Abstract

The application discloses a micro-mixing chip and a micro-channel reaction system. The micro-mixing chip includes at least two material inlets and a reaction process pipeline, and each of the material inlets is connected to the reaction process through a material preheating pipeline. At the same end of the process pipeline, a material outlet is formed at the other end of the reaction process pipeline, and the material preheating pipeline and the reaction process pipeline curve extend and form a plurality of U-shaped corners. Due to the large specific surface area, the microchannel reactor device provided by the present invention simplifies the steps in the process of process amplification, saves manpower and material resources, and has the advantages of uniform mass and heat transfer, small equipment footprint, low energy consumption, continuous process operation, High safety factor and other advantages. Moreover, the configuration of the micro-reaction chip is flexible, and the heat exchanger is independent, which can adapt to the continuous production process of various materials and multi-step complex processes.

Description

technical field [0001] The application relates to a chemical reactor, in particular to a micro-mixing chip and a micro-channel reaction system, belonging to the field of microfluidic technology. Background technique [0002] Chemical reactor is the equipment to realize the chemical reaction process, which is widely used in fine chemical industry, pharmaceutical, petrochemical industry, metallurgy, light industry and other industries. Commonly used reaction equipment, such as batch reactors, is flexible and simple, and can meet the needs of various reaction processes. However, due to the small specific surface area of ​​the batch reactor, multi-step optimization is required in the process of process scale-up, which consumes a lot of manpower and material resources, and there are uneven mass and heat transfer, large equipment footprint, high energy consumption, and continuous production. Difficulty, low safety factor and other shortcomings. In the 21st century, with the rise...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing microchannel reactors are not flexible enough, and are not very adaptable to many chemical processes, especially to the reaction processes of various materials and multi-step temperature zones;

[0006] 2. The integration of the reaction module and the heat exchange module is too high, so for many reactions that can only be carried out at room temperature, the equipment cost is relatively high
