[0002] The characteristics of continuous microreactors include continuous flow reaction, instantaneous micro-processing capacity, high efficiency, safety, and automation. Compared with traditional tank reactor technology, continuous flow technology has many obvious advantages: greatly improved mass transfer and heat transfer efficiency, high reaction safety, small material consumption and precise ratio, and easy application in actual production.

[0003] Continuous microreactors can be divided into active or passive mixing types. Although active mixing has higher mixing efficiency, it requires external fields or energy sources such as magnetic fields, electric fields, acoustic fields, and thermal fields, resulting in high energy consumption, complex structure, and difficulty in manufacturing. Passive mixing, on the other hand, does not require any external energy source, has a simple structure, and is easier to prepare. However, current passive mixing microreactors use a simple channel structure for mixing during use, resulting in poor mixing efficiency, reducing reaction efficiency, and being unfavorable for processing and use.

[0007] A jet hood is provided on one side of the inner wall of the mixing chamber, and a plurality of jet holes are opened on the surface of the jet hood. A spoiler baffle is fixedly connected to the middle of the inner cavity of the mixing chamber, and a plurality of triangular blocks are fixedly connected to the inside of the mixing chamber, and microporous gaps are formed between the plurality of triangular blocks.
