Zusammenfassung:An equipment for drying sludge by a heating wire is provided to remove water contained in the sludge by supplying energy using electric heat to water-containing sludge, thereby increasing temperature of the sludge. An equipment for drying sludge by a heating wire comprises: a screw conveyor rotated by a motor(4) to transfer sludge; a hopper(5) which is installed at a starting point of the screw conveyor, and through which sludge is injected into the screw conveyor; a discharge port(7) installed at an end part of the screw conveyor to discharge dry cake; a steam outlet(8) for discharging steam discharged in the sludge drying process from the inside of the screw conveyor to the outside thereof; and a heating wire(1a) installed on an outer part of a pipe surrounding the screw conveyor. The steam outlet discharges steam to the outside by the rotation of a fan. The heating wire is wound around the pipe by a rotation type winding method, a lattice type winding method, or a combination thereof.
