Manufacturing method for solid fuel of organic sludge by using dry pyrolysis gas formed from thermal decomposition of waste

摘要

The present invention relates to a method and apparatus for recovering energy generated by combustion of a pyrolysis gas obtained by pyrolysis of municipal waste, such as steam, from a boiler, drying carbonized organic sludge using the remaining combustion gas to obtain a solidified fuel of good quality, The present invention relates to a method for producing a solidified fuel compact of an organic sludge produced by using a dry gas, comprising: a pyrolysis step of generating a combustible dry gas obtained by pyrolyzing industrial waste and municipal waste; A combustion process for combusting the combustible dry gas; An energy recovery step of recovering heat energy generated in the combustion of the carbon monoxide gas by the steam in the boiler and supplying the heat to the drier; Mixing the organic sludge with an adjuvant for inhibiting flocculation in an amount of 1 to 15 wt% based on the sludge to prepare a sludge mixture; An injection molding process for molding the sludge mixture produced by the mixture manufacturing process so as to have a certain shape and shape; Wherein the molded article molded by the injection molding process is dried in the dryer so as to have a moisture content of 10 wt% or less, a low calorific value of 3,000 to 3,500 kcal / kg and a carbon content of 40 to 45 wt% on a dry basis, Lt; / RTI According to such a method for producing a solidified fuel molded body of organic sludge, it is possible to obtain a high-quality fuel molded body having a high calorific value by using the energy generated by the combustion of the carbonized gas obtained by pyrolyzing municipal wastes and the like.
