APPARATUS FOR MANUFACTURING SOLID FUEL USING WASTE AND METHOD THEREOF

摘要

The present invention relates to an apparatus and a method for manufacturing a solid fuel by using waste. The apparatus of the present invention includes: a crushing unit crushing the waste; a first sorting unit sorting and separating a ferrous metal material from the crushed waste; a second sorting unit sorting the waste sorted by the first sorting unit on a predetermined particle size basis; a third sorting unit sorting and separating a metal material from the waste sorted by the second sorting unit; a fourth sorting unit sorting and separating the waste from which the metal material is separated by the third sorting unit into a heavy material, an intermediate material, and a light material depending on moisture content; and a first drying unit drying the waste sorted as the intermediate material by the fourth sorting unit. According to the present invention, the solid fuel is formed by the use of the waste sorted as the light material by the fourth sorting unit and the intermediate material dried by the first drying unit, and air in a boiler chamber is used as a drying heat source. Since the waste sorted as the light material and the waste sorted as the intermediate material are used as the solid fuel, waste drying capacity and drying costs can be reduced, solid fuel production can be performed in an economical manner, and an increase in rate of recovery can be achieved.
