Beschreibung
Zusammenfassung:	The utility model discloses a multi-stage waste heat recovery drying system which can carry out two-stage recovery on waste heat, realize echelon utilization of energy, improve the energy utilization rate, recover moisture exhaust waste heat and improve the drying efficiency. The multi-stage waste heat recovery drying system comprises a first recovery system and a second recovery system. The first recovery system comprises a first circulating air duct, a high-temperature heat exchanger, a rear drying chamber, a dehumidification air duct and a medium-temperature heat exchanger. An inlet of the high-temperature heat exchanger is connected with a waste heat source; the rear drying chamber is located on the air outlet side of the high-temperature heat exchanger. The medium-temperature heat exchanger is arranged in the dehumidification air duct; the second recovery system comprises a second circulating air duct, a low-temperature heat exchanger, a front drying chamber, a moisture removal air duct, an air source he
