摘要
为深入研究和开发臭氧氧化结合化学吸收同时脱除多种污染物技术,阐明了石灰石吸收脱除臭氧氧化产物(SOx和NOx)的吸收反应机理,通过气液固平衡理论对石灰石浆液吸收SOx和NOx特性进行了分析研究。理论分析表明:烟气中CO2对SOx和NOx吸收的影响可以忽略,并给出浆液在吸收容量所能承受的最大气液比。当[CaCO3]=0.05mol/1时,临界点M=600-700;当[CaCO3]=0.1mol/1时,临界点M=1200~1300;当[CaCO3]=0.15mol/1时,临界点M=1900~2000。
The reaction mechanisms of ozone with many pollutants are being elucidated, and the dynamic processes of ozone, oxidizing NOx and SO2 , simulated. According to thermodynamic principles, the partial pressures of SOx and NOx , after the flue gas wet state's simultaneous desulfurization and denitration reactions respectively with Ca (OH)2 and CaCO3 , have both attained equilibrium, are then calculated. Calculation results show that as an absorbent, Ca(OH)2 is superior to CaCO3 , and both of them exhibit nearly a 100% removal efficiency. Figs 4,table 1 and refs 9.
