WASTE INCINERATION WASTE GAS AND TREATMENT METHOD FOR DUST

摘要

PROBLEM TO BE SOLVED: To provide a treatment method for waste incineration exhaust gas and dust which is capable of efficiently treating the dust generated from a waste incinerator and decreasing the amount of the dust which must be subjected to landfill disposal. SOLUTION: The waste gas generated from the municipal refuse incinerator 10 is first collected by a cyclone 12 and is then collected by a bag filter 15, by which the dust in the waste gas is classified and captured to a coarse grain component having a lower content of heavy metals and a fine grain component having a high content of the heavy metal. The coarse grain component is loaded into the waste incineration furnace 10 and is discharged together with the freshly formed incineration residues. The fine grin component is sent to a stabilization treating device 20 and is subjected to the stabilization treatment of the heavy metals.
