[0037] The wet sludge in the external sludge bin 4 is transported by a screw conveyor and enters the sludge dryer 11 from the external sludge bin 4 along the external wet sludge feed port 111. The high-temperature gas transported from the drying gas inlet 112 serves as a fluidized drying medium for the wet sludge.

The granular sludge enters the first cyclone separator 12 under the action of the fluidizing wind, and the first cyclone separator 12 separates the granular sludge and the gas.

[0038] The solid particles separated by the first cyclone separator 12 enter the dry sludge bin 14 through the screw conveying device, and then the solid particles enter the mixing bin 15 through the screw conveying device, and the solid particles are mixed with the biomass particle fuel in the mixing bin 15. The solid particles and the biomass particle fuel are discharged from the discharge port of the mixing bin 15 together, and then enter the incinerator 21 through the fuel feed port 211 through the screw conveying device for combustion.

The solid particles enter the slag bin 213 at the bottom of the furnace of the incinerator 21 along the pipeline from the solid particle discharge port of the second cyclone separator 22. The slag in the slag bin 213 can be collected regularly, and the slag can be used as a construction resource such as road construction. The high-temperature flue gas discharged from the exhaust port of the second cyclone separator 22 enters the sludge dryer 11 from the dry gas inlet 112. The high-temperature flue gas separated by the second cyclone separator 22 can provide a drying heat source for the fluidized drying of wet sludge in the sludge dryer 11, so that the temperature in the sludge dryer 11 is maintained at 400-500℃.

[0039] The gas separated by the first cyclone separator 12 is discharged from the gas outlet of the first cyclone separator 12 and first enters the dust collector 13. The dust collector 13 is connected to the alkali washing tower 31. The gas discharged from the dust collector 13 flows into the alkali washing tower 31, the oxidation tower 32, and the UV photolysis tower 33 in sequence for further purification.
