Fundamental study and application progress in gas-liquid non-thermal plasma multiphase reactors

等离子体作为物质存在的一种基本形态,因其特有的高活性而不同于固、液、气三种形态,逐渐应用于多个领域,并发展成了一门新兴学科。由于冷等离子体参与的气液化学反应能产生更多的活性物质,而且液体的流动性能够强化活性物质的传递,因此,气体放电产生的冷等离子体与液相反应在许多领域表现出重要的应用价值,更具有探究意义。综述了几种冷等离子体的放电形式以及表征技术,重点阐述了气液冷等离子体多相反应器的不同结构以及应用,并对气液冷等离子体技术发展进行了展望。

As a basic form of the substance,plasma is different from solid,liquid and gas due to its unique high activity.It has gradually been applied in many fields and has developed into a new discipline.The gas-liquid chemical reaction involving the non-thermal plasma could generate more reactive oxygen species,and the fluidity of liquid could enhance the mass transfer in the gas-liquid non-thermal plasma reactors.So,the reaction of nonthermal plasma generated by the gas discharge and liquid phase has an important application value in many fields. The discharge patterns and characterization techniques of various non-thermal plasmas are reviewed.Furthermore, the different structures and applications of gas-liquid non-thermal plasma multiphase reactors are highlighted,and then the development of gas-liquid non-thermal plasma is prospected.
