Description

technical field

[0001] The invention belongs to the technical field of enhanced liquid-liquid rapid microcosmic mixing reaction device, in particular to a single reflection-ring nozzle impingement flow structure and a single reflection-ring nozzle impingement flow-rotating packed bed device. Background technique

[0002] The impingement flow is the core area of ​​high momentum transfer, high turbulent kinetic energy, and high turbulent kinetic energy dissipation formed between two feed pipes by two or more fluids colliding with each other. The axial velocity quickly changes from zero to radial velocity. , so as to quickly carry out micro-mixing, the quality of micro-mixing can change the quality of the product, and then change the nature of the product. The rapid reaction process affected by micro-mixing in industry includes polymerization reaction process, reaction crystallization process and some biochemical reaction processes.
