The invention discloses a net-shaped electrostatic defogging water collecting device. The net-shaped electrostatic defogging water collecting device can effectively remove frog and recover water resources. The defogging water collecting device comprises cathode corona wires, a fog drop trapping net rack, a high-voltage constant-current power supply unit, a defogging device shell and a water collecting tank; more than one cathode corona wire is uniformly arranged on a cathode wire fixing frame to form a cathode corona wire set; the cathode wire fixing frame is connected to the high-voltage constant-current power supply unit; the fog drop trapping net rack is arranged in the defogging device shell; and the water collecting tank is arranged at the bottom of the defogging water collecting device. According to the net-shaped electrostatic defogging water collecting device, fog enters the defogging water collecting device, at the moment, the high-voltage constant-current power supply unit supplies direct-current high-voltage electricity to the cathode corona wire set, an electric field is formed between the cathode corona wire set and the anode fog drop trapping net rack, fog drops are pushed onto the fog drop trapping net rack under the action of the air buoyancy and the electric field force, a small part of fog drops are deposited and fall off, and most of the fog drops fall into the water collecting tank and a fog source device along the fog drop trapping net rack under the action of the gravity.
