Abstract

The invention belongs to the technical field of micro-channels, and relates to a micro-channel reaction and mixing device which comprises a fluid mixing unit, and the fluid mixing unit comprises a substrate; at least two fluid inlets at different positions are formed in the side wall of the substrate; a central hole penetrating through the substrate is formed in the substrate; the substrate is provided with micro-channel main paths of which the number corresponds to that of the fluid inlets; a mixed micro-channel and a micro-channel branch are arranged on the substrate; the fluid inlet is communicated with the central hole through the micro-channel main path; and the micro-channel main path is communicated with the central hole through the mixed micro-channel and the micro-channel branch.The micro-channel reaction and mixing device provided by the invention has the advantages that the mixing area is increased, the mixing effect is enhanced, and the mixing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of microchannels and relates to a multichannel mixing structure, in particular to a microchannel reaction and mixing device which is especially suitable for the fields of multiphase flow mixing, reactors and the like. Background technique [0002] Microchannels are tiny structures used for heat exchange, mass transfer, and multiphase mixing that are manufactured by special micromachining techniques such as photolithography and etching. Due to its small size, large specific surface area, high heat exchange efficiency, and strong heat and mass transfer capabilities, microchannels can achieve uniform mixing of materials and efficient heat transfer in a short period of time, and are widely used in biological, chemical, microelectronics and other technical fields. . At present, the micro-mixing structure has developed rapidly, but there are still problems such as low production efficiency and uneven mixing. The...
