Abstract

PURPOSE: To increase treating capacity and make maintenance free by disposing multicyclones in multistages in series.
CONSTITUTION: The furnace top waste gas exhausted from the top of a blast furnace 1 is collected of coarse dusts by a dust catcher 2. The furnace top waste gas having been collected of coarse dusts is collected of dusts stepwise by the 1stW3rd multicyclones 3W5, and finally it is purified to the dust concn. having no hindrance in the driving of a furnace top pressure turbine 6. The dust concn. of the furnace top waste gas coming out from the 3rd multicyclone 5 permits sufficient operation of the furnace top pressure rurbine 6 if it has blades of high abrasion resistance. Since in the 1stW3rd multicyclones 3W5 the dusts of respectively different grain size constitutions are captured, this is useful in the case of utilizing the dusts for raw materials of iron ore pellet.
