The decreasing of aerosol emission concentration by a liquid film neutralization
Abstract: The method of liquid film neutralization is used for air purification from aerosols in gaseous technological emissions, as well as in exhaust gases of power plants (including ship ones). When contaminated gas moves between vertical plates with a liquid film flowing through them, aerosols are efficiently deposited on its surface. To reduce the concentration of particles, the authors of this article have designed and manufactured an experimental stand in which a film flow of water is set on a vertical brass plate, air containing aerosols simulated by powders for thermal spraying with different bulk densities moves upward along the film. In the experiments, the air velocity, the initial concentration and density of aerosols were changed.
Analysis of the results showed that the deposition of solid particles occurs over a relatively small section of the contact length of 0.3–0.4 m. At the same time, their content in the flow decreases sharply with an increase in the density of aerosols, their initial concentration and air flow velocity. In all modes, the concentration decrease reaches 60–100%.
