The invention discloses an overboard discharge pipe of a desulfurization system. The overboard discharge pipe comprises a reinforced bracket, an external plate, a carbon steel pipe, a first plastic coating layer, a second plastic coating layer and a carbon steel flange, wherein the carbon steel pipe further comprises an internal pipe wall and an external pipe wall; the first plastic coating layeris attached to the internal pipe wall, and the second plastic coating layer is attached to the first plastic coating layer; the external plate vertically sleeves the external pipe wall, the external plate is connected to one end of the carbon steel pipe, the reinforced bracket is connected to the external plate and the external pipe wall, and the carbon steel flange sleeves the other end of the carbon steel pipe. A fan-shaped through hole is further formed in the reinforced bracket, and the fan-shaped through hole is adjacent to a connecting position of the external plate and the carbon steelpipe. The overboard discharge pipe body is prepared from ordinary steel, the overboard discharge pipe is reliable and firm and high in safety, and moreover, a construction technology that the overboard discharge pipe is welded to the external plate of a ship body through full penetration welding is easily adopted. The making material is simple, the making difficulty is low, the purchasing cycle isshort, and the purchasing cost and the making cost are low.
