Verfahren zur Reinigung von Müllverbrennungsabgasen und zur Herstellung einer wässrigen Salzlösung |
摘要 |
<p>An exhaust gas scrubbing process for gases carrying ash from incineration of waste which contains heavy metals, sodium chloride and chlorine-organic residues comprises washing the ash with water after dust extraction in a first stage and dispersing the dust in at least part of this water at a later stage to produce an aqueous sodium chloride solution. The process comprises: (1) extracting the dust from the exhaust to produce separately ash and the dustless gas; (2) treating the dustless gas with a basic reactant containing a soda compound to provide a gas containing dust; (3) extracting the dust from this gas to produce dust and a dustless gas; (4) dispersing the dust in water to produce an aqueous medium containing an aqueous sodium chloride solution; and (5) purifying the aqueous medium to produce the sodium chloride solution and a solid residue containing at least part of the heavy metals. After the first stage the ash is washed and the washing water re-used in stage (4).</p> |
