| 摘要 |
<p>The invention relates to a method for waste paper processing, starting at a predominantly high consistency of at least 8% in the first stages with a dissolution (soaking) including a coarse sorting stage. The invention is characterised in that, in the case of waste paper which contains a high proportion of de-inking waste paper provided with printing inks, the three first process stages, namely the soaking, coarse purification and the further, extensive dissolving of the wastepaper, in this order, are carried out with a considerable reduction of the waste paper shreds to the usual speck size at a consistency of at least 13%, and the soaking takes place with a substantial addition of dissolving chemicals, and that the waste paper is fed to the process together with essentially all the heavy impurities contained in the waste paper, such as parts of wood, glass, plastic or metal including pieces of metal ties of the waste paper bales. <IMAGE></p> |
