DUST COLLECTING DEVICE AROUND MOLTEN IRON/MOLTEN SLAG DROPPING HOLE PART IN BLAST FURNACE

摘要

PURPOSE: To improve the dust collecting efficiency around molten iron/molten slag dropping hole part and to enable sufficient dust collection while reducing dust collection blasting quantity. ;CONSTITUTION: In the blast collecting device around the molten iron/molten slag dropping hole part for a blast furnace, a dust collecting hood 30 is arranged around the molten iron/molten slag dropping hole part, and also, three or more pieces of air injection heads 40 and an air suction hole 41A are arranged around this dropping hole part. With these air injection heads 40 and air suction hole 41A, an artificial whirlwind is generated in this dropping part.;COPYRIGHT: (C)1994,JPO&Japio
