Sludge desiccation burning integral treatment method and device

A method of integrated treatment of sludge drying and incineration is provided, which comprises the follow steps of: feeding sludge into a rotary-type sludge dryer, introducing a part of moderate-temperature fume inside a fluidized bed incinerator into the rotary-type sludge dryer to heat and evaporate the water in the sludge, feeding the obtained semi-dried sludge into the fluidized bed incinerator; introducing the other part of moderate-temperature fume into an air pre-heater, heating the fist-stage and second-stage air of the fluidized bed incinerator, transferring parts of ash and bed media exhausted from the fluidized bed incinerator to the rotary-type sludge dryer, and mixing with the sludge inside the rotary-type sludge dryer. A device for implementing the method comprises a storage feed device, the rotary-type sludge dryer and the fluidized bed incinerator. The invention realizes the integrated treatment of drying and incineration; omits the intermediate links between the drying and incineration links, such as sludge cooling, sludge storage, sludge transportation and heat medium drying; simplifies the system; reduces the occupied area; and reduces the investment and cost.
