TREATMENT METHOD AND TREATMENT DEVICE FOR CONVERTING CHLORINE-CONTAINING WASTE INTO RAW MATERIAL FOR CEMENT
Document Type and Number:
WIPO Patent Application WO/2011/122527
Kind Code:
A1
Abstract:
The disclosed treatment method for converting chlorine-containing waste into raw material for cement is capable of removing harmful components such as heavy metals contained in the chlorine-containing waste and then safely discharging the same, and is capable of treating, as the chlorine-containing waste, waste incineration fly ash, alkali bypass dust, chlorine bypass dust, or a mixture of these, and effectively recycling the same as raw materials and fuel for cement. As shown in figure 1, fly ash and desalinated dust are treated, and harmful substances such as selenium and other heavy metals are removed from the chlorine-containing waste that is fly ash or desalinated dust by means of polymer flocculants and chelating agents, or by means of reducing agents, polymer flocculants, and electrolytic treatment. The solid components generated during treatment are used as raw material for cement.
