Method for cleaning exhaust gases produced by a sintering process for ores and/or other metal-containing materials in metal production

A process for cleaning exhaust gases produced by a sintering process of metal-containing waste, wherein

• the sintering exhaust gas comprises at least one of the following harmful substances in addition to at least one of CO2, CO, O2, and H2O:
• NOx, SO2, HCl, Hg, dioxins, furans, dust sublimatable or condensable residues from a low-temperature pyrolysis process, heavy hydrocarbons, heavy metals, and potassium and/or sodium compounds,
• wherein
• the harmful substances are essentially eliminated from the sintering exhaust gases in at least two steps by at least one adsorption and/or absorption agent in a single moving bed in a moving bed reactor system, the moving bed including a particle layer (stage I) disposed above a flow input area and below an adsorption layer (stage II) of the moving bed, and
• at least one of the harmful substances SO2, HCl, sublimatable or condensable residues, heavy hydrocarbons, heavy metals and potassium and/or sodium compounds is bound absorptively or adsorptively and the harmful substances are trapped by adhesion in the flow input area or the Particle layer (stage I) of the moving bed, and
• the substantial removal of NOx and the adsorptive or absorptive removal of dioxins and furans takes place in the adsorption layer (stage II) in the moving bed.
