Different materials further undergo "dynamic annular gap microchannel continuous flow reaction" here, and the mass transfer and heat transfer effects are very good; in addition, the inner wall of the outer sleeve 5 can be smooth or have an internal thread, and the gap between the inner wall of the outer sleeve 5 and the external thread of the inner sleeve 3 is controlled to be about 10 threads to form an annular gap reaction channel for the material.
