Investigation of the Influence of Acoustic Field on Vapor Precipitation over Plating Bath

The influence of acoustic field on vapor precipitation process taking place above the plating bath is analyzed in the article. Lateral exhaust hood was used to remove aerosol from open surface tank. It is shown that acoustic field generator generates sound waves with sound level of 130-140 dB at 1-4 kHz frequencies. Such acoustic field increases aerosol coagulation and its precipitation back to the liquid. This results in the reduction of aerosol concentration in the air, reduction of costs of air purification equipment and increase of its removal efficiency.
