Abstract
PURPOSE: To prevent the generation of dust by subjecting sludge to drying, granulating and melt treatment successively.
CONSTITUTION: The sludge is treated by a dehydrating machine 1 to separate and concentrate a liquid phase and the concentrated sludge A is, moreover, sent to a drying machine 2 to be dried by hot air B. The sufficiently dried sludge A2 in a drying machine 2 is sent to a granulating and molding machine 3 and, herein, the said dried sludge A2 is molded into a granular sludge A3 with appropriate particle size and thrown into a melting furnace 4. A melting furnace 4 receives fuel and air C and the granular sludge A3 is combusted under high temp. and high pressure to melt inorg. substance and this molten substance is exhausted as a vitreous slag D.
