Claim 4:
5. The method of drying inorganic sludge with molten slag according to claim 4, wherein the method comprises: conveying the slag and the sludge to the drum containing the steel balls with respective conveying devices; and after the water content of the sludge is reduced to 3 wt %-15 wt %, conveying a mixture of the steel slag and the dry sludge to a slag-sludge separation device with a slag-sludge conveying device positioned at an outlet end of the drum to separate the steel slag from the dry sludge, wherein dust, sulfides and organic compounds existing in a tail gas generated during the drying of the sludge enter a tail gas treatment device from a drum outlet, and the gas is discharged after the treatment; wherein the dust separated in the tail gas treatment enters a tail sludge mixing device from a dust mud outlet of the tail gas treatment device, mixes with sludge to be dried, and is then conveyed to the drum through a mud conveying pipeline.
