Problems solved by technology

[0011] In the research field of microfluidic extraction, some microchannel chips with extremely small feature sizes are often used to study the relevant condition parameters of microfluidic extraction effects. Although these chips can obtain high single-stage extraction efficiency, due to their extremely low throughput , and the processing cost of the microfluidic chip is high, it is very unrealistic to apply it in industrial production

Abstract

The invention relates to a microfluid extraction expansion reactor for 3D printing and applications of the microfluid extraction expansion reactor and belongs to the technical field of microfluid extraction. The microfluid extraction expansion reactor for 3D printing comprises a water phase inlet, an oil phase inlet, a mixed liquid collection cavity I, a liquid drop cutting sieve plate, a mixed liquid collection cavity partition, a mixed liquid collection cavity II, a mixed reaction microchannel, a mixed liquid collection cavity III and a mixed liquid outlet. The applications of the microfluidextraction expansion reactor for 3D printing comprise single-phase or multi-phase reaction microfluid extraction including a gas-liquid reaction and a liquid-liquid reaction. According to the microfluid extraction expansion reactor for 3D printing, oil-water two phase separating is rapid, the extraction reaction time is short, and an emulsifying phenomenon cannot occur.

Description

technical field [0001] The invention relates to a 3D printed microfluidic extraction expansion reactor and its application, belonging to the technical field of microfluidic extraction. Background technique [0002] In the past 20 years, as a new concept, microfluidic technology has shown its great advantages in the field of chemical engineering. At present, microreactors have been rapidly developed and applied in a wide range of fields. Although the use of microreactors does not change the reaction mechanism and intrinsic kinetic characteristics, when the two-phase fluid is in the micron scale or even smaller, their interface-to-volume ratio will increase sharply, and the concentration gradient of elements will be large. As a result, the mass transfer driving force is greatly improved. The traditional industrial extraction process requires strong stirring to enhance the mass transfer effect between the two phases, which will form a large number of water-in-oil and oil-in-wa...
