摘要 利用实验手段研究了双管式电弧等离子体发生器的特性,包括旋流进气特性、伏安特性和运行热效率等,建立了基于双管式电弧等离子体发生器的数学模型。结果表明,旋流流速对电极烧蚀速率有较大影响,电弧电压降和发生器热效率随电流增加而下降,发生器热效率随气流量增大而增大。根据相似理论建立的数学模型能够准确模拟等离子体发生器的负电弧动态电阻伏安特性。以上研究可为大功率、长寿命双管式电弧等离子体发生器的开发及其在材料制备和环境保护领域的应用提供参考。 The characteristics of a double tube arc plasma generator are studied by means of experiments,including the study of vortex chamber characteristics,the volt-ammetric characteristics and the thermal efficiency.The mathematical model based on the double tube electrode arc plasma generator is established.The results show that the vortex chamber velocity has great influence on the electrode specific erosion,the arc voltage drop and thermal efficiency decrease with the increase of current,and the generator thermal efficiency increases with the increase of gas flow.The mathematical model based on the similarity theory can accurately simulate the negative arc dynamic resistance volt-ammetric characteristics of the plasma generator.The above results can provide a reference for the development of high-power,long-life double tube electrode arc plasma generator technology and its application in the solid waste melting and coal-fired boiler ignition.
