PURIFICATION APPARATUS FOR CONVERTER GAS, CONVERTER SYSTEM AND PURIFICATION METHOD OF CONVERTER GAS

摘要

PROBLEM TO BE SOLVED: To provide a purification apparatus for converter gas, a converter system and a purification method of converter gas which improve the recovery rate of dust although being low-cost.;SOLUTION: A purification apparatus for converter gas includes a temperature reduction tower which cools converter gas to such a temperature as not to allow water condensation by spraying water into converter gas introduced externally, an upstream cyclone part 310 having a first pipe body 312 in which a first swinging space 316 for swinging of the converter gas introduced from the temperature reduction tower is formed internally and a downstream cyclone part 330 which has a plurality of second pipe bodies 332 provided internally with a second swinging space 336 for swinging of the converter gas introduced from the first swinging space 316 and smaller in volume than the first swinging space 316 and guides the converter gas swung through the first swinging space 316 to the second pipe bodies 332.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2016,JPO&INPIT
