Problems solved by technology

[0004] The present invention aims at the complex structure and long mixing time of the prior art, and for the multiphase reaction system, the pipeline area between the cylinder body and the multi-layer spiral wound microchannel reactor is prone to condensation of droplets and bubbles and even fluid separation. layer phenomenon, which greatly reduces the mass transfer and heat transfer rate and other defects. A multi-scale microstructure reactor is proposed. Rapid and efficient mixing and reaction under low volume, and the internal structure is simple, easy to process and manufacture

Abstract

A multi-scale microstructure reactor comprises: a lower fluid inlet tube; and an upper fluid inlet tube, a mixing chamber, capillary tubes, a collection chamber cover plate, a collection chamber and an outlet tube which are sequentially communicated from top to bottom, wherein the upper fluid inlet tube and the lower fluid inlet tube are coaxially arranged, and are respectively communicated with the mixing chamber from the top and the bottom of the mixing chamber; and the capillary tubes are radially arranged around the lower fluid inlet tube in an annular array, and cling to the inner wall ofthe mixing chamber. The multi-scale microstructure reactor has the advantages of flexibility in operation, good mixing effect, realization of large-scale production of chemical products through adjusting the quantity and the size of the capillary tubes, and great application potential in the fields of chemistry, chemical engineering, petrochemicals and medicines.

Description

technical field [0001] The invention relates to a technology in the field of chemical rapid mixing and reaction equipment, in particular to a multi-scale microstructure reactor. Background technique [0002] In many fields such as chemistry, chemical industry, petrochemical and pharmaceutical, especially the reaction and separation (such as gas absorption and liquid-liquid extraction) process of chemical industry, it is necessary to carry out the mixing and reaction between two or more strands of materials. The quality of the reaction process has a crucial relationship with the smooth progress of the reaction process and the overall process efficiency. Traditional mixing and reaction equipment, such as fully mixed tanks and tower reactors, have a large processing capacity and can meet the requirements of large-scale industrial production. However, because the mixing scale or reaction scale in the equipment is at the millimeter or even larger The efficiency is low, the resid...
