Abstract
To suppress running cost including facility cost and chemical cost low in washing treatment of incineration ash and dust contained in extracted cement kiln combustion gas by minimizing harmful influence to operation due to scale adhesion in accordance with increased amount of chlorine-bypass dust generated. A washing system 1 of the present invention comprises a dissolution tank 32 for dissolving fly ash A to water W; a dissolution tank 22 for dissolving dust D contained in a combustion gas extracted from a flow passage from an inlet end of a cement kiln to a bottom cyclone to water W; and a vertical filter press 11 for separately performing filtration of a slurry S2 fed from the dissolution tank 32 and filtration of a slurry S1 fed from the dissolution tank 22 respectively. The washing system 1 may further comprise water treatment facilities 33 to 35 for water-treating a filtrate L3 of a slurry including the fly ash discharged from the vertical filter press and water treatment facilities 23 to 27 for water-treating a filtrate L1 of a slurry including the dust discharged from the vertical filter press.
