Problems solved by technology

However, in most scientific research or some pharmaceutical production processes, it is necessary to achieve pilot-level process research, and the existing micro-mixers cannot match the mesoscopic size suitable for scientific research, which limits the researchers' experiments.
For example, when a micro-mixer with a channel size of about 200um is used for a pilot-scale process, the reaction pressure drop is relatively large, resulting in harsh requirements for materials, and it is difficult to achieve pilot-scale process development and production
If other suitable equipment is equipped to meet the reaction needs, it will increase the development cost

Abstract

The invention discloses a micro-mixing device and a manufacturing method, the micro-mixing device comprises a plurality of micro-mixers arranged in series, each micro-mixer comprises a shell and a mixing structure, a reaction space is formed in the shell, and the shell is also provided with a reaction inlet and a reaction outlet which are respectively communicated with the reaction space; the mixing structure comprises a plurality of mixing units which are communicated in sequence, and a plurality of mixing runners which are distributed in a star-type manner are formed in the mixing units. According to the technical scheme, the mixing effect of the micro-mixing device is improved, the application range of the micro-mixing device is expanded, and the scientific research cost is reduced.

Description

technical field [0001] The invention relates to the field of microchemical technology, in particular to a micromixing device and a manufacturing method thereof. Background technique [0002] The micro-mixer is used to achieve full mixing of different reactants under micro-channel conditions, and is an important part of micro-chemical technology. [0003] Among the existing micro-mixers, most of them have a channel size below 100um or above 2000um. Among them, the micro-mixer with a channel size below 100um is only suitable for kinetic verification or condition screening of chemical synthesis reactions; while the channel size is 2000um The above micro-mixers are only suitable for large-volume industrial production, and there are many types of industrial micro-mixers available on the market. For example, patent CN201711253614.0 introduces a double T-shaped planar curved micro-mixer. The channel size of the mixing structure is 100um, which is used in microfluidic chips, mainly...
