摘要
论述了脱硫脱硝技术现状 ,通过分析比较得出 :湿法脱硫投资和运行成本高 ,产生的副产品无法进行再利用 ;电子束烟气脱硫脱硝技术投资和运行比湿法脱硫低 2 0 %～ 30 % ,但需要严格庞大的放射线防护设施 ,电子加速器昂贵 ,电子能量损失大。笔者提出强电离放电可以将烟气中的SO2 氧化 ,然后生成固体微粒 (NH4) 2 SO4,提高反应速率 ,简化流程 ,有望真正解决我国的SO2 和NOx
Technique situation of removal of SO\-2 and NO\-x is described,and conclusions as follows were drawn through analysis and comparison.The investment and running cost of SO\-2 removal in wet method is high and its byproducts are useless;on the contrary,the cost of SO\-2 removal by use of electron beam is 20%～30% lower than that in wet method,but strict and giant radiation defensive facilities are needed with expensive accelerator and energy loss is great.Also it is suggested that SO\-2 in flue gas can be oxidized and solid particles of (NH\-4)\-2SO\-4 are generated by using strong barring dielectric discharge which is hopeful to resolve the pollution of SO\-2 and NO\-x in China.
