Wet method dedusting device

The invention discloses a wet method dedusting device. The wet method dedusting device comprises a supersonic wave atomizer used for spraying fine water mist towards a smoke flow channel to form a supersonic wave atomization region, a sound wave generator arranged at the lower position of the supersonic wave atomizer according to the smoke flow direction and used for establishing a sound field in the smoke flow channel to form a sound wave coagulation region, and a liquid drop catcher arranged at the lower position of the sound wave generator according to the smoke flow direction used for catching coagulated dust-containing liquid drops after going through the supersonic wave atomization region and the sound wave coagulation region to form a dust collection region. The place occupation, the total cost and operation expenses of the dedusting device after wet method desulphurization can be lowered greatly, waste water discharge of wet method dedusting is reduced, and ultraclean discharge of a chimney is achieve
