摘　　要：针对含氮氧化物工业尾气的氧化度的问题,提出超重力场中臭氧氧化-强化吸收氮氧化物的方法。考察了超重力场强度、臭氧用量、通过旋转填料的气速和液体喷淋密度对氮氧化物去除率的影响。实验结果表明,超重力场组合臭氧氧化-强化吸收氮氧化物的显著影响因素为超重力场强度和臭氧用量,在最佳操作工艺条件下氮氧化物的去除率高于90%。在此基础上,分析了超重力场中臭氧氧化-强化吸收氮氧化物作用机制。Intensifying absorption of NO~ in high gravity field in presence of ozone is studied according to NOx with low oxidation degree in industrial tail gas. The influences of various operating parameters, including high gravity number, ozone adding amount, gas flow velocity and liquid spray density on the NOx removal efficiency are investigated. The results indicate that the most prominent parameters are high gravity number and ozone amount. Under the experimental condition, the NOx removal efficiency is over 90%. The mechanism of NO~ ozone oxidation and intensifying absorption in high gravity field is analyzed as well.
