Nano-micro interface enhanced reaction system

Abstract

The invention provides a nano-micro interface enhanced reaction system, which comprises a reactor body which is used as a reaction chamber for a gas-liquid, liquid-liquid, liquid-liquid-solid, liquid-solid or gas-liquid-solid multi-phase reaction medium to carry out reaction so as to ensure that the multi-phase reaction medium can fully react; and a nano-micro interface generator which is connected with the reactor body and is used for crushing a gas phase and / or a liquid phase in the multi-phase reaction medium into nano-micro bubbles and / or nano-micro liquid drops of which the diameters arenano-scale in a preset mode in the nano-micro interface generator before the multi-phase reaction medium enters the reactor body, so as to increase the phase boundary mass transfer area between the gas phase and / or the liquid phase and the liquid phase and / or the solid phase in the reaction process. The problem that the mass transfer rate is affected due to the fact that the phase boundary contactarea of a reaction phase is small in the using process of an existing reaction strengthening system is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of reaction strengthening, and in particular relates to a nano-micro interface strengthening reaction system. Background technique [0002] The interface refers to the boundary area between the material phase and the phase. It exists between the two phases, and the thickness is about several molecular layers to tens of molecular layers. It is different from the concept of "surface" in geometry. The surface here has Thickness is the interface region between specific material phases. Interfacial phenomenon occurs with mass transfer, and it has a significant impact on the mass transfer process. Extraction, rectification, absorption, gas-liquid reaction, liquid-liquid reaction, gas-liquid-solid three-phase reaction are typical interfacial mass transfer processes. Although the existing heterogeneous reaction system has strong adaptability to raw materials and simple operation, due to the large scale of gas and / ...
