Abstract
This utility model discloses a device for drying sludge using waste heat from boiler flue gas. The device includes a support frame, a housing, and a drying tray. The top of the housing has an opening. The support frame supports the housing. The drying tray is installed on the top of the housing and is used to hold sludge. One end of the housing is connected to an air inlet hood, and the other end is connected to an air outlet hood. The air inlet hood allows boiler flue gas to enter, and the air outlet hood allows boiler flue gas to exit. Several heat dissipation pipes are installed inside the housing, with one end connected to the air inlet hood and the other end connected to the air outlet hood. This utility model solves the problem of high energy consumption in existing low-temperature sludge dryers.
