Title:
SINTERING MACHINE FOR SINTERED ORE
Document Type and Number:
WIPO Patent Application WO/2018/155368
Kind Code:
A1
Abstract:
The present invention provides a sintering machine that is for obtaining sintered ore and that is capable of increasing the circulation volume of exhaust gas and ensuring high safety by effectively preventing air leakage. This sintering machine 50 for obtaining sintered ore is provided with a sintering bed 6 comprising a plurality of pallet trolleys that run on a track laid out on a floor surface, and is used for manufacturing a sintered ore by continuously combusting a sintering raw material stacked on the pallet trolleys while the pallet trolleys are moving. The sintering machine 50 is also provided with: an exhaust duct 2 which has disposed therein a main blower 14 for drawing exhaust gas from below the sintering bed 6 and discharging the exhaust gas to outside; an exhaust gas circulation hood 1 that provides a cover above the pallet trolleys; an exhaust gas circulation duct 3 that connects the exhaust duct 2 and the exhaust gas circulation hood 1; and a seal part for hermetically sealing a gap between the exhaust gas circulation hood 1 and the floor surface, wherein the exhaust gas circulation hood 1 is configured so as to maintain the pressure therein at a level equal to or lower than the atmospheric pressure.
