The invention discloses a demisting device for an expressway. The demisting device comprises a framework, wherein a metal net is arranged at the periphery of the framework; vertical corona wires are arranged in the framework; the upper ends and the lower ends of the corona wires are both connected with the framework through insulators; insulator surrounding barrels are arranged at the upper ends and the lower ends of the framework; an electric heating ring is arranged in each insulator surrounding barrel. The demisting devices disclosed by the invention are vertically arrayed at two sides and a middle isolating belt of the expressway, and are powered by a high-voltage direct current power supply; the corona wires are enabled to be connected with a negative electrode of the power supply, and the metal net is enabled to be connected with a positive electrode of the power supply; after the power supply is powered on, negative charges discharged by the corona wires penetrate through meshes of the metal net and are attached to water mist particles; the water mist particles obtaining the charges are trapped by the metal net or be adsorbed by the ground under the action of electrostatic attraction, so that the aim of demisting is achieved.
