Abstract

PURPOSE:To stabilize always the property of fine powder of separated into oxide and to change the property of fine powder arbitrarily, by introducing a gas to be sent by pressure, e.g., exhaust gas, air, etc. to a jetting nozzle for waste hydrochloric acid, blending the gas with concentrated waste hydrochloric acid, and jetting the blend. CONSTITUTION:The exhaust gas 8 from the roaster 1 consisting of the burner 6 for drying, the jetting nozzle 2 for waste hydrochloric acid, the exhaust vent 4 for the exhaust gas 8 containing HCl gas, and the outlet part 5 for separated iron oxide is sent through the cyclone 10 for collecting dust coarsely to the recovery column 12 for hydrochloric acid, and the concentrated waste hydrochloric acid 16 is pressurized and sent to the jetting nozzle 2 for waste hydrochloric acid. While, the jetting nozzle 2 for waste hydrochloric acid is equipped with the gas introduction path 7 to give the jetting nozzle 3, and a proper gas sent by pressure is introduced to the jetting nozzle 2.
