臭氧含量对模拟烟气中SO_2去除效果的研究

The Effect of Ozone Content on the Removal of SO_2 from Simulated Flue Gas

针对燃煤电厂废气脱硫的成本高、效率低及二次污染问题,实验研究了不同O_3含量在N_2/SO_2/O_2体系中对SO_2脱除效果的影响。实验结果表明了在O_3的强氧化作用下,N_2/SO_2/O_2体系中SO_2的最高去除率达到了95%以上,且O_3生成量越高,去除率则越高,能量利用率也随之升高。但是,反应装置中的副产物氮氧化物在一定程度上降低了脱硫效果。

In view of the high cost,low efficiency and second pollution of the traditional desulfurization methods in the coal fired power plants,the effects of different O3 content on the removal of SO2 in the N2/SO2/O2 system were studied. The results showed that under the strong oxidation of O3,the highest removal rate of SO2 in N2/SO2/O2 system was over 95%. The higher the concentration of O3 was,the higher the removal rate and the higher energy utilization efficiency were. However,the production of nitrogen oxides has inhibiting effect on the desulphurization reaction.
