Abstract

The invention belongs to the technical field of strengthening liquid-liquid rapid micro-mixing reaction device, specifically a single reflection-ring nozzle impact flow structure and a rotating packed bed device, which solves the current situation of liquid and liquid rapid reaction in unequal feeds The problem of uneven micro-mixing caused by the following. The impingement flow structure includes main feed pipes with different diameters, sleeves and baffles. The sleeve is sleeved outside the main feed pipe. The center of the plate is located on the axis of the main feed pipe and the casing; the rotating packed bed device, the impingement flow structure is arranged in the cavity of the rotor and arranged along the axis of the rotor. The invention has the advantages of uniform mixing of unequal feeds, quick response, short reaction time and large processing capacity; it is especially suitable for rapid reaction of unequal feeds with a material ratio of not 1 in the industrial reaction system and certain viscosity characteristics reaction system.

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. [0003] Currently, impinging flow structure...
