PURPOSE: A sludge drying system using superheated steam is provided to rapidly dry a large amount of sludge by removing moisture by first destroying the cell membrane of organic matters of sludge with superheated steam. CONSTITUTION: A sludge drying system using superheated steam comprises a sludge supply unit(110), a sludge transfer unit(120), a steam supply unit(130), a hot air supply unit(140), and a sludge discharge unit(150). The sludge supply unit extrudes and pelletizes sludge and then supplies the sludge. The sludge transfer unit transfers the sludge pelletized from the sludge supply unit through a mesh conveyor belt(121). The stem supply unit directly injects superheated steam to the sludge to destroy the cell membrane of organic matters. The hot air supply unit supplies hot air to the sludge and dries the sludge. |
