PROBLEM TO BE SOLVED: To provide a deposit drying device using waste heat capable of reducing a cost for drying a deposit.SOLUTION: A gasifying and melting system 200 includes a gasifying and melting furnace 300, an exhaust gas treatment device 14 for discharging dust 15, a neutralizing column 16 for discharging a deposit 20, and a mist Cottrell precipitator 17, etc. A deposit drying device 100 installed alongside the gasifying and melting system 200 includes a floor 30 and an upper space 32 for housing the deposit 20, a mixing plow 40 for plowing up the deposit 20, and a lower space 31 formed under the floor 30, etc. Into the upper space 32, heated air Awhich is obtained by cooling air A that has been used for cooling the gasifying and melting furnace 300 is introduced. Meanwhile, hot water 23 via heat exchange in a second heat exchanger 12 is allowed to pass through a road heating part 36 in the lower space 31 and thus the deposit 20 housed in the upper space 32 is dried while plowed up by the mixing plow 40. |
