SOLID FUEL PRODUCTION APPARATUS USING SLUDGE

摘要

Disclosed is an apparatus for producing solid fuel using sludge. The apparatus for producing solid fuel using sludge according to one embodiment of the present invention comprises: a biogas production unit including an anaerobic digestion tank which is installed in the middle of a supply path where sludge is supplied to a power generation unit and which receives the sludge, and also including a digestion sludge storage unit for storing digestion sludge treated in the anaerobic digestion tank; a mixed preheating unit for being supplied with the digestion sludge stored in the digestion sludge storage unit, and performing a preheating; an oil tank unit for supplying oil to the digestion sludge supplied to the mixed preheating unit; a dry unit for drying the digestion sludge passed through the mixed preheating unit; a process unit for being supplied with the digestion sludge dried in the dry unit, thereby drying at a predetermined temperature, and at the same time, transforming the digestion sludge into smaller digestion sludge; and a heat supply unit for being supplied with waste heat recovered from the power generation unit, thereby supplying heat necessary for the mixed preheating unit, the dry unit, and the process unit.
