Acoustic system of airborne gas-dust removal includes a body horizontally arranged and having a cylindrical shape with a contact zone in the central part, to the left of which there are at least two nozzles of the irrigation device in series along the axis of the housing, and on the right side of the housing after the contact zone there is a drip trap with a drain in the lower part of the housing. For each injector, nozzles for compressed air and water connections are provided. Each of the nozzles comprises a housing with a screw coaxially located at the bottom of the housing and a fitting in the upper part of the housing with a cylindrical fluid inlet connected to the diffuser, an axisymmetric housing and a fitting. Screw is pressed into the body to make cylindrical chamber above said screw and aligned with the diffuser
