Nanoparticle removal and exhaust gas cleaning using gas-liquid interfacial nonthermal plasma.

We investigate the removal of air pollutants containing nanoparticles with a wet-type plasma reactor that generates a gas-liquid interfacial nonthermal plasma. To evaluate the performance of this reactor, we prepare a simulated exhaust gas using polystyrene latex particles, as well as gas cylinders of synthesized air and mixed gas of nitric oxide (NO) and sulfur dioxide (SO 2 ). We achieve a partial collection efficiency of more than 99% for nanoparticles. Moreover, we obtain removal efficiencies exceeding 99% and 81% for SO 2 and NO x , respectively. We confirm that the proposed reactor is useful for the simultaneous removal of nanoparticles, NO x , and SO x . [ABSTRACT FROM AUTHOR]
