This paper describes and discusses experimental results on the absorption of sulphur dioxide in electrified water sprays, either when the polluted gas is treated as is or when the gas is exposed to a corona source to ionize the sulphur dioxide. The experiments revealed that an electrified spray with a charge‐to‐mass ratio of 50 μC · kg⁻¹ enabled the absorption rate of droplets to double, regardless of their polarities. Corona charging gave rise to an increase in the SO₂ depletion rate over the scrubber wall, while negligible effects appeared on the actual droplets absorption rate. These findings suggested that faster absorption rates mostly, though not uniquely, depend on the modifications on the morphological and interfacial properties of the sprayed droplets induced by the free electric charge imposed on their surface. Conversely, the absorption rates were negligibly affected by the electrical interactions between droplets (either charged or uncharged) and the sulphur dioxide ions/radicals originating from the corona source.

电喷雾液滴吸收二氧化硫

本文描述并讨论了带电喷水吸收二氧化硫的实验结果，无论是按原样处理被污染的气体，还是将气体暴露于电晕源以使二氧化硫离子化的实验结果。实验表明，带电喷雾的荷质比为50μC·kg ^-1，可以使液滴的吸收速率增加一倍，而无论极性如何。电晕充电导致SO ₂的增加洗涤塔壁的耗竭率，而对实际液滴吸收率的影响可忽略不计。这些发现表明，更快的吸收速率在很大程度上（尽管不是唯一的）取决于施加在其表面的自由电荷对喷雾液滴形态和界面性质的影响。相反，吸收速率受液滴（带电或不带电）与源自电晕源的二氧化硫离子/自由基之间的电相互作用的影响可忽略不计。
