【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]=0.05 mol/l时,临界点M=600~700;当[CaCO3]=0.1 mol/l时,临界点M=1200~1300;当[CaCO3]=0.15 mol/l时,临界点M=1900~2000。图4表1参9更多还原

【Abstract】 The reaction mechanisms of ozone with many pollutants are being elucidated,and the dynamic processes of ozone,oxidizing NO_x and SO₂,simulated. According to thermodynamic principles,the partial pressures of SO_x and NO_x,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.更多还原
