Abstract
PURPOSE: To reduce the size of an SOX treating apparatus by feeding most of waste gas with higher SOX concn. from the latter half of wind boxes to a sintering zone to make unslagged lime capture SOX and desulfurizing part of the waste gas with higher SOX concn.
CONSTITUTION: Starting materials 1 for sintering such as fine iron ore, 8W 20wt% limestone powder, coke breeze and a little water are charged onto a pallet, ignited in a firing furnace 3, and sintered. Unslagged lime remains in the sintering zone 17 in the form of quick lime even after passing through the sintering zone 16. Waste gas with higher SOX concn. from the latter half of wind boxes 14 is fed to the zone 17 through a cyclone 11 and a hood 6 to make the unslagged lime capture and fix SOX. On the other hand, waste gas with higher SOX content from the wind box #10 is desulfurized with a desulfurizer 12 having a dust collecting function and discharged from a chimney 14 together with waste gas with lower SOX concn. passed through a dust collector 8.
