Pilot Study on Wall Drying Characteristics of Municipal Sludge Flue Gas
Inter-wall flue gas dryer is a self-developed high-temperature flue gas heat through inter-wall heat transfer to dry sludge of the new equipment.The principle is to use the high-temperature flue gas generated by other systems to evaporate the moisture in the sludge through the heat exchange of the flue gas through the two channels of the shell side and shaft side of the equipment;it acts as a drying agent for sludge.The flue gas used by the inter-wall drying equipment has no direct contact with the sludge,the tail gas of drying is greatly reduced,the cost of treatment is lower,and the energy loss is reduced by the energy conversion between the flue gas and other media.
