Combined desulfurization and particle removal device for tail gas of ship

The invention relates to a combined desulfurization and particle removal device for tail gas of a ship. The device comprises a cyclone dust collector consisting of a tail gas inlet pipe, an outer barrel, an inner barrel, a conical barrel and a dust hopper; the inner wall of the outer barrel of the cyclone dust collector is provided with a first insulation layer, and the outer wall of the inner barrel of the cyclone dust collector is provided with a second insulation layer; a discharge electrode is arranged on the second insulation layer, and a dust collecting electrode is arranged on the firstinsulation layer; a sound wave generator is also arranged. According to the cyclone type combined desulfurization and particle removal device for the tail gas of the ship, particulate matters and SO2in the tail gas are removed by washing, so that the emission of harmful pollutants in the tail gas of the ships can be effectively reduced; the particulate matters and the SO2 in the tail gas are removed at the same time by u
