RECYCLING METHOD AND RECYCLING APPARATUS FOR WASTE INCINERATION ASH
To provide a recycling method and apparatus to make it possible to desalinate waste incineration ash for its recycling, and to effectively recover precious metals from waste incineration ash.SOLUTION: An apparatus for recycling waste incineration ash, which comprises: (i) a slurrying device 3 that produces slurry S1 by adding water W to waste incineration ash BA; (ii) a first classifier 4 that classifies the slurry S1 into coarse grain-containing slurry S2 and a fine grain-containing slurry; (iii) a first wet specific gravity sorting device 9 that performs wet specific gravity sorting of the slurry S2 separated by the first classifier 4; (iv) a second classifier 5 that classifies the fine grain-containing slurry separated by the first classifier 4 into three or more slurry groups having different grain sizes (e.g., S3A to S3D and S4); (v) a second wet specific gravity sorting device 11 that separately performs wet specific gravity sorting of each of the slurry groups having different grain size (e.g., S3A to S3D) separated by the second classifier 5, except for the slurry group (e.g., S4) that has a grain size smallest among those separated by the second classifieir 5; and (vi) desalination devices 13-15 that perform desalinating of the slurry group S4 having the smallest grain size separated by the second classifier 5.SELECTED DRAWING: Figure 1
【課題】ごみ焼却灰を脱塩してセメント原料として利用すると共に、ごみ焼却灰から効率よく貴金属を回収する。【解決手段】ごみ焼却灰ＢＡに水Ｗを添加してスラリー化するスラリー化装置３と、スラリー化装置でスラリー化されたごみ焼却灰スラリーＳ１を粗粒子を含むスラリーＳ２と、微粒子を含むスラリーに分級する第１の分級装置４と、第１の分級装置で分離された粗粒子を含むスラリーを湿式比重選別する第１の湿式比重選別装置９と、第１の分級装置で分離された微粒子を含むスラリーを３以上の粒群に分離する第２の分級装置５と、第２の分級装置で分離された最小径の粒群以外の各粒群のスラリーＳ３Ａ〜Ｓ３Ｄを別々に湿式比重選別する第２の湿式比重選別装置１１と、第２の分級装置で分離された最小径の粒群のスラリーＳ４を脱塩する脱塩装置１３〜１５とを備えるごみ焼却灰の資源化装置１。【選択図】図１
