Title:
The exhaust air remaining-heat sludge drying system of a non-contact form
Document Type and Number:
Japanese Patent JP5913369
Kind Code:
B2
Abstract:
A non-contact sludge drying system with flue gas heat according to the present invention includes a dryer, and further includes an economizer, a high-temperature flue gas heat recovery device, and an air preheater that are successively disposed in the flue along a flue gas flowing direction. A heater is disposed in the dryer, the high-temperature flue gas heat recovery device is connected to the heater by a circulation pipe, a heat transfer medium is disposed in the circulation pipe, a heat transfer medium driving device is disposed on the circulation pipe, and the dryer is connected to a sludge vapor recovery system. The non-contact sludge drying system with flue gas heat according to the present invention uses the flue gas heat from a thermal power plant boiler or another industrial boiler as a heat source to further dehydrate and dry the dehydrated sludge of the sewage treatment plant, so that the dried sludge can be used as a fuel with certain heat of combustion or composted for further treatment.
