Zusammenfassung:The invention discloses a sludge disc steam drying system, a drying machine rotating shaft extending out of a disc drying machine is connected with a power part, the disc drying machine is provided with a wet sludge passing port, a drying tail gas outlet, a saturated steam inlet and a dry sludge discharging port, the system is provided with a heat exchanger, a heat source input port of the heat exchanger inputs superheated steam, and a heat source output port of the heat exchanger outputs the superheated steam. A heat source output port of the heat exchanger is connected with a saturated steam input pipeline through a temperature and pressure reducer, the steam input pipeline is connected with a saturated steam inlet of the disc drying machine, and a heat exchange outlet of the heat exchanger is connected with the steam input pipeline. The source of superheated steam of the whole system device is stable, the amount of saturated steam required by sludge drying is effectively increased, wet sludge can be effici
