APPARATUS FOR TREATING HIGH-TEMPERATURE SLAG

Japanese Patent JP2008013784

A

To provide an apparatus for cooling high-temperature slag, which does not cause a problem of producing dust, does not generate strongly alkaline water in a cooling process, does not require a long cooling period of time, and can recover the slag as a valuable resource.

This apparatus comprises: a plurality of cooling boxes 2 for primarily cooling the high-temperature slag which has been discharged from a furnace; a transportation device 4 for transporting the slag which has been cooled to a predetermined temperature to a hopper 9 with the use of a transporting box 4a for fractionation; and a dry-cooling device 5 for secondarily cooling the slag which has been supplied from the hopper 9, by bringing the slag into contact with the cooling air while transporting the slag. A vibrating fluidized-bed type cooling device or a rotary type cooling device can be used for the dry-cooling device 5. A classifier 6 is preferably connected at the subsequent stage of the dry-cooling device 5.
