电化学工业涉及基础原材料生产和先进功能材料制备,是化工、冶金、材料等多学科交叉的过程工程。降低工业能耗、提升产品品质和制备新型材料是电化学工业可持续发展的推动力。然而,现存的核心瓶颈问题是缓慢的液相传质和气泡分离。超重力作为一种新型的过程强化技术,近年来在化学工业中获得广泛的关注。本文理论分析了超重力对电化学过程对流传质和气泡分离的强化作用,介绍和证实超重力下可实现水/氯碱电解过程强化,以及电沉积功能材料(如金属箔、活性电极、导电聚合物等)的结构与性能调节,将有望为电化学工业提供新的发展契机。

Electrochemical industries, pertaining to the production of raw materials and preparation of func-tional materials, are multi-interdisciplinary involving chemical engineering, metallurgy and material science. The reduction of energy consumption, the improvement of product properties and new materials are the motives for the development of electrochemical industries. The key issues are mass transfer and bubble disengagement. Su-pergravity as a new process intensification technology has attracted more and more attention. The intensification actions of supergravity on mass transfer and bubble disengagement are analyzed theoretically in this paper. It is confirmed that chlor-alkali electrolysis and water electrolysis can be enhanced obviously due to the rapid disen-gagement of gas bubbles from electrolytic system under supergravity field. The structure and properties of elec-trodeposited functional materials (such as metal foils, active electrode and conductive polymer) can be also ad-justed. Supergravity technology is an opportunity to advance the traditional electrochemical engineering.
