This paper presents a novel concept of local push-pull ventilation system used to remove aerosol particles from open surface tanks. Sound waves generated by aerodynamic sound generator are introduced into the push air flow of lateral exhaust hood and used to agglomerate aerosol particles. Results of calculation of parameters of sound generator and aeroacoustic air flow are presented. It is established that 5-10 mu m aerosol particles are aggregated better at frequencies below the ultrasonic range (1-5 kHz) and aerosols with a particle size of less than 5 pm are more effectively aggregated at ultrasonic frequencies. It was experimentally established that the relative air humidity measured above open surface tank is decreased up to 1.6 times in presence of acoustic field as compared with humidity obtained for conventional push-pull air removal system. It is also obtained that increase of the temperature of the liquid increases the aerosol removal efficiency of lateral exhaust hood enhanced by aeroacoustic air flow.
