【摘要】 采用模拟燃煤烟气方法,研究了石灰湿法燃煤烟气脱硫过程中CO2钙化问题,指出了烟气脱硫过程中CaCO3的生成量与脱硫液初始pH值、SO2初始浓度、温度的关系,得出抑制CaCO3生成的条件,为减缓石灰湿法燃煤烟气脱硫存在的结垢现象,对石灰湿法燃煤烟气脱硫系统的实际应用具有一定的指导和借鉴价值。更多还原

【Abstract】 Simulated flue gas of coal burning is used in this m et hod,the calcification problem of CO2 when SO2 removed in flue gas by limewa sh method is studied,the relationbetween the generating amount of CaCO3 and t he initial PH value of limewash solution,the relation between the generating am ount of CaCO3 and the initial concentration and temperatureof SO2 in flue g as are indicated.The restrained factors of CaCO3 generation can we get,these results are very helpful to retard the the calcification of CO2 when SO2 rem oved in flue gas by limewash method,these results can also be used as a guidanc e or a reference for the application of desulphurization systems of coal burning flue gas by limewash method.更多还原
