The invention provides a dust removal device capable of realizing acoustoelectric enhanced fine particle coagulation. The dust removal device is used for dust removal of flue gas and comprises a charged unit, a coagulation unit and a dust removal unit, wherein the flue gas sequentially passes through the charged unit, the coagulation unit and the dust removal unit, the flowing direction of the flue gas is in an S shape, the charged unit, the coagulation unit and the dust removal unit are provided with sound wave generators corresponding to the flowing direction of the flue gas, the charged unit comprises a polar plate and a barb electrode; the coagulation unit comprises a shunting partition plate and a graphene turbulent-flow column; and the dust removal unit comprises a round rod electrode and an arc-shaped polar plate. According to the invention, coagulation of fine particles is enhanced by utilizing the coupling effect of a sound field, an electric field and a turbulent-flow field; the graphene turbulent-f
