Disclosed are a measurement system for micro-mixing and a measurement method thereof. The measurement system comprises a mixing device, a light enhancement unit, an observation unit, an image acquisition unit, a display device and a tracer injection device; the light enhancement unit comprises a light-emitting device, a light-focusing device and a reflecting device; the observation unit comprises an observation window; the image acquisition unit comprises a distortion-free lens and an image acquisition device which are connected in sequence, and a central axis of the distortion-free lens is in alignment with a central axis of the observation window. The measurement method is performed in the measurement system provided by the present application. In the present application, the brightness of visual field is improved, the light interference on target image is shielded off, the process of micro-mixing can be observed in real time, and thereby the micro-mixing efficiency can be evaluated.

Measurement system for micro-mixing and measurement method thereof

A micro-mixer and use thereof for synthesis of barium sulfate particles is disclosed. The micro-mixer includes feeding tubes, reservoirs, a mixing channel, a buffer reservoir and a sampling tube. The mixing channel is made of hydrophobic materials and processed into a spiral structure, in which baffles are set in interval arrangement at both sides of the channel wall. The types of the baffles include leaning-forward baffles, vertical baffles and leaning-backward baffles. Setting the baffles helps produce local secondary flow in the mixer, which enhances fluids mixing process. The micro-mixer is suitable to rapid reactions or precipitation processes, whose reaction time is much less than mixing time, and has broad application prospects in many fields involving mixing reaction such as pharmaceutical and chemistry industry.
