为了解二氧化氮在硫化钠溶液中的吸收机理，采用具有平面气液界面的搅拌釜式反应器，测量了稀释后的二氧化氮在硫化钠溶液中的化学吸收率。测定了不同实验条件下的吸收率，讨论了实验条件对吸收率的影响。结果表明，在本研究范围内，二氧化氮吸收率随硫化钠浓度、二氧化氮进口浓度和烟气流量的增加而增加，随反应温度和烟气中氧含量的增加而降低。
To understand the absorption mechanism of nitrogen dioxide into a sodium sulfide solution, a stirred tank reactor with a plane gas-liquid interface was used to measure the chemical absorption rate of diluted nitrogen dioxide into sodium sulfide solution. The absorption rates under various experimental conditions were measured and the effects of experimental conditions on nitrogen dioxide absorption rate were discussed. The results show that, in the range of this study, nitrogen dioxide absorption rate increases with increasing sodium sulfide concentration, nitrogen dioxide inlet concentration, and flue gas flow rate, but decreases with increasing reaction temperature and oxygen content in flue gas.
