摘要： The present invention provides a method and an apparatus for treating a chlorine-containing waste, which can separate and recover a chlorine component from a chlorine-containing waste, and also can achieve a high chlorine removal thereby obtaining a high purity chlorine compound, and can decrease the amount of water for recovering chlorine. The method for treating a chlorine-containing waste of the present invention comprises a washing/filtrating step of adding water to the chlorine-containing waste, followed by mixing to form a first slurry, separating the first slurry into a solid and a filtrate through filtration, and using the resulting solid as a cement raw material; a filtrate treating step of adding a reducing agent and a pH adjustor to the filtrate to form a sediment containing heavy metal and calcium contained in the filtrate, and separating the sediment through filtration; a crystallization step of concentrating the filtrate, from which the sediment has been removed, through heating and evaporation to form a second slurry in which a chlorine compound contained in the filtrate has been crystallized, separating the second slurry into a solid containing a chlorine compound and a mother liquor, and recovering the solid; and a separated mother liquor treating step of returning a portion of the mother liquor to a cement manufacturing facility.

摘要： An apparatus for manufacturing cement clinker is disclosed in which raw material powder of cement pre-heated and partially pre-calcined by a pre-heating unit such as a suspension pre-heater (or a provided pre-calciner') is charged into a granulating furnace as to be granulated, thus-obtained granulated material is charged into a sintering furnace as to be sintered, and the sintered material is cooled and recovered by a cooling unit, the apparatus having a granulating furnace so that the granulating performance of the granulating furnace is improved. A fuel supply unit for forming a local hot region is disposed immediately above a porous perforated distributor disposed in the throat portion between the granulating furnace and the sintering furnace so that the granulating furnace is formed into a jet fluidized bed structure, the lower portion of the granulating furnace has an inverse frustum of circular cone (a cone portion) so formed as to cause the granulated material to form a downward moving bed, and raw material powder of cement is blown through the side wall of the cone portion, and it is sufficiently dispersed in the moving bed before it reaches the local hot region.
