DEVICE FOR COOLING AND HEAT RECOVERY OF SINTERED ORE TO REUSE HEAT GENERATED IN COOLING OF SINTERED ORE

摘要

PURPOSE: A device for cooling and heat recovery of sintered ore is provided to increase the recovery rate and temperature of heat recovered when cooling sintered ore and to implement smooth cooling of sintered ore. ;CONSTITUTION: A device for cooling and heat recovery of sintered ore comprises a heat exchange unit(110), a sintered ore insertion unit(120), a cooling nozzle(114), and a cooling air supply unit(140). The heat exchange unit comprises a sintered ore insertion hole, a sintered ore discharge hole, a recovered heat exhaust guide(113), and a recovered heat exhaust hole. The sintered ore insertion unit periodically supplies a fixed amount of hot sintered ore crushed with a crusher to the heat exchange unit. The cooling nozzle is arranged close to the inner discharge part of the heat exchange unit and discharges cold air for cooling the sintered ore accumulated in the heat exchange unit and generating recovered heat. The cooling air supply unit is connected to the cooling nozzle in order to provide cold air.;COPYRIGHT KIPO 2011
