Rotary filling bed based on hydrophilic-hydrophobic combined filler, and system

Abstract

The invention provides a rotary filling bed based on a hydrophilic-hydrophobic combined filler, and a system. According to the present invention, a hydrophobic filler and a hydrophilic filler are combined into a combined filler, and when a liquid is cut by the filler, the hydrophobic filler can fully disperse the liquid to uniformly disperse the liquid in the filler region, and the wettability of the hydrophilic filler can make the liquid spread sufficiently so as to increase the wetting fraction of the filler, such that different mixing effects can be achieved through the reasonable combination; the numbers of the hydrophilic filler layers and the hydrophobic filler layers in the combined filler are limited, such that the liquid droplet coalescence phenomenon generated by the liquid in the single hydrophobic filler region and the liquid turbulence reduction phenomenon generated by the liquid in the single hydrophilic filler region can be avoided; and the negative effect caused by the hydrophilicity can be alleviated or offset by the hydrophobicity while the negative effect caused by the hydrophobicity can be alleviated or offset by the hydrophilicity, such that the mass transfer and mixing performance of the hydrophilic-hydrophobic combined filler can be further improved by applying the hydrophilic-hydrophobic combined filler in the rotary filling bed.

Description

technical field [0001] The invention relates to the technical field of reactors, and more specifically, to a rotating packed bed and system based on hydrophilic-hydrophobic combined packing. Background technique [0002] Packing is the core structure of the high-gravity rotating bed, and it is also one of the key factors affecting the mass transfer and mixing of the rotating packed bed. The structure, material, and surface properties of the filler will affect the dispersion of the liquid in the rotating bed, the size of the droplet, the thickness of the liquid film, and the pressure drop, which will further affect the mass transfer and mixing process of the high-gravity rotating bed. Therefore, in order to further optimize the mass transfer and mixing performance of the rotating packed bed, it is particularly important to study the packing structure, material and surface properties of the rotating packed bed. At present, for the application of hydrophilic materials or hydro...

AI Technical Summary

Problems solved by technology

At present, for the application of hydrophilic materials or hydrophobic materials in rotating packed beds, they only focus on a single hydrophobic filler or a single hydrophilic filler for a specific reaction, without considering the particularity of the hypergravity environment itself, and there are many deficiencies
