摘要

目前，微通道因其优异的传质性能被广泛应用于液液异质传质系统中。然而，由于传统微通道的被动混合原理，传质性能的提高存在瓶颈。本研究提出了一种新型旋转毫米通道反应器（RMCR），能够通过离心力实现液-液异质传质增强。通过高速摄影技术观察了 RMCR 中的三种典型流动模式，即蛞蝓流、平行液滴流和平行流。随着总容积流量和转速（N）的增加，RMCR 的容积传质系数（K O a）也随之增加。与 N = 0 r/min 相比，RMCR 的 K O a 在 200 r/min 时增加了 61.5%，范围在 0.013 到 0.021 s-1 之间。本研究提出的 RMCR 可望应用于具有高处理能力和易堵塞的液-液异质传质系统。

Liquid-liquid flow pattern and mass transfer in a rotating millimeter channel reactor

Currently, microchannels are widely used in liquid-liquid heterogeneous mass transfer systems due to its excellent mass transfer performance. However, because of the passive mixing principle of traditional microchannels, the improvement of mass transfer performance has a bottleneck. This work proposes a novel rotating millimeter channel reactor (RMCR), capable of achieving liquid-liquid heterogeneous mass transfer enhance by centrifugal force. Three typical flow patterns of slug flow, parallel-droplet flow, and parallel flow in the RMCR were observed by high-speed photography technology. The volumetric mass transfer coefficient (K O a) of the RMCR increased with the increase of the total volumetric flow rate and rotational speed (N) increased. Compared with N = 0 r/min, the K O a of the RMCR increases by 61.5 % at 200 r/min, ranging from 0.013 to 0.021 s−1. The RMCR proposed in this work is expected to be applied to the liquid-liquid heterogeneous mass transfer system with high processing capacity and easy plugging.

期刊介绍： Chemical Product and Process Modeling (CPPM) is a quarterly journal that publishes theoretical and applied research on product and process design modeling, simulation and optimization. Thanks to its international editorial board, the journal assembles the best papers from around the world on to cover the gap between product and process. The journal brings together chemical and process engineering researchers, practitioners, and software developers in a new forum for the international modeling and simulation community. Topics: equation oriented and modular simulation optimization technology for process and materials design, new modeling techniques shortcut modeling and design approaches performance of commercial and in-house simulation and optimization tools challenges faced in industrial product and process simulation and optimization computational fluid dynamics environmental process, food and pharmaceutical modeling topics drawn from the substantial areas of overlap between modeling and mathematics applied to chemical products and processes.
