METHOD FOR CLEANING EXHAUST GASES PRODUCED BY A SINTERING PROCESS FOR ORES AND/OR OTHER METAL-CONTAINING MATERIALS IN METAL PRODUCTION

摘要

The solid metal or other metal-containing materials and ores in metal production consisting of mixed ore which can be combined A method for purifying exhaust gas according to the sintering process, the sintering process and distillation, using the catalyst NOx is removed, and also other harmful components, in particular SO ₂ and the mass is removed, the sintering exhaust gas Optionally after pre-purification stage, at least one absorption in a single fluidized bed of a fluidized bed reactor systems and / or hazard minutes from the sintering exhaust gas in at least two steps by the absorber is removed, the gas phase component SO ₂ , HCl, sublimable or condensable residues, at least one of the hydrocarbons and heavy metals, and optionally a potassium and / or sodium compound is coupled to an absorption or suction, the particulate component flows from the input region, and optionally bonding the adjacent lower layer of the fluidized bed is trapped by the selective adsorption or absorption of nitrogen and substantial removal of gas phase components, such as dioxins and furans is characterized in that it is carried out in a lower layer in the layer region adjacent to the fluid bed type region adjacent to the flow.
