DEVICE FOR TREATING WASTE GAS OF ASH MELTING FURNACE

摘要

PROBLEM TO BE SOLVED: To diversify the technique of the subject device for treating the waste gas of an ash melting furnace. SOLUTION: This device is a device for treating the waste gas of a DC resistance ash melting furnace 1. The device is provided with a combustor 2 for burning the CO gas in the waste gas 12 discharged from the ash melting furnace, a cooler 3 for spraying water into the waste gas discharged from the combustor 2 to cool the waste gas, an HCl removal reactor 4 for introducing the waste gas discharged from the cooler 3, sending slaked lime or a slaked lime slurry downward to neutralize and remove the HCl gas in the waste gas and depositing the dust in the waste gas on the slaked lime to remove the dust and a bag filter 5 for introducing the waste gas from the reactor 4 and removing the dust.
