Efficient low-consumption air flow dehumidification device for deep dehydration of semidry sludge

The invention relates to an efficient low-consumption air flow dehumidification device for deep dehydration of semidry sludge. The air with unsaturated humidity is utilized and passes through an efficient low-consumption dehumidification device, and moisture content of the sludge is further reduced. The efficient low-consumption air flow dehumidification device for the deep dehydration of the semidry sludge comprises an air inducing device, a multifunctional barrel, three-dimensional shovelling plates (material lifting plates and material discharging plates) and a sealing tail, wherein the material lifting plates vertical to the axial direction of the barrel are arranged on the inner wall of the barrel, and the material discharging plates are arranged at the bottoms of the material lifting plates. When the barrel rotates forward, the sludge is lifted, the introduced air with unsaturated humidity takes moisture away, and no material is discharged due to a sealing plate. When the barrel rotates reversely, the s
