WATER AEROSOLS SPRAYING FOR SO_2 AND NO_x REMOVAL FROM GASES UNDER E-BEAM IRRADIATION

摘要

The gas-phase transport process of an admixture to the surface of spraying aerosol droplets has been experimentally investigated with reference to E-beam gas cleaning processes. The rate of SO_2 uptake by alkali aerosol droplets with average radius ? 30 μm has been measured in gas-aerosol jet using light absorption technique. It has been shown that the rate of gas-phase transport is described by the molecular flux of the admixture. Gas-liquid reactions are considered to explain the observed improvement of radiation-induced NO removal in the presence of spraying alkali aerosol.
