PURIFICATION APPARATUS FOR BLAST FURNACE GAS, BLAST FURNACE AND PURIFICATION METHOD OF BLAST FURNACE GAS

摘要

PROBLEM TO BE SOLVED: To provide a purification apparatus for blast furnace gas which can improve energy recovery efficiency at low costs, a blast furnace and a purification method of blast furnace gas.SOLUTION: A purification apparatus for blast furnace gas includes an upstream cyclone part 110 having a first pipe body 112 in which a first swinging space 116 for swinging of blast furnace gas introduced externally is formed internally and a downstream cyclone part 130 which has a plurality of second pipe bodies 132 provided internally with a second swinging space 136 for swinging of the blast furnace gas introduced from the first swinging space 116 and smaller in diameter or volume than the first swinging space 116 and guides the blast furnace gas swung through the first swinging space 116 to the second pipe bodies 132.SELECTED DRAWING: Figure 2
