Abstract
PURPOSE: To convert a harmful heavy metal into a water-insoluble compound by adding alkali and iron salt to collected dust containing a heavy metal discharged from the dust collector of a waste-matter incinerator to mix them and then by heating them in the incinerator.
CONSTITUTION: Into collected dust 10 discharged from dust collector 3 provided to waste-matter incinerator 2, iron salt 9 such as iron chloride and iron sulfate and alkali 8 such as sodium hydroxide and calcium hydroxide are mixed by mixer 7. Consequently, iron salt 9 is converted into a hydroxide by reacting with the alkali and collected dust 10 containing this hydroxide is thrown in and heated in incinerator 2, wherein the mixed hydroxide is dehydrated into a heavy metal oxide and at the same time, they combine together to form stable crystal. Next, crystallized dust 5 is discharged to the outside of the system together with ashes 6 and then disposed as reclaiming material.
