NaOH气液两相滑动弧放电处理含硫废气的研究
Treatment of Flue Gas Containing Sulfur by Gas-Liquid Phase Gliding Arc Discharge Combined with NaOH
摘要
Abstract
To improve the efficiency of gas-liquid two-phase gliding arc discharge to treat thermal power plant waste gas,the traditional pure water phase is replaced by NaOH solution.In this study,through the measurements of applied voltage,discharging current and emission spectrum,the influence of NaOH on electrical and optical characteristics of the discharge is analyzed.The concentration of SO2 is selected as the observation index.Then the SO2 removal efficiencies of NaOH and pure water phase have been analyzed.The product concentrations under different experimental conditions are also discussed,such as discharge time and gas flow rate.The results show that NaOH solution instead of pure water phase enhances discharge strength under the same conditions,and intense ionization in the discharge produces a large number of OH radicals.At the same time,compared with pure water,the sulphur removal efficiency of NaOH solution increases by 5%~7%,while the product of SO3 content reduces by about 50%.关键词
