Abstract

By mixing kilned, unslaked lime and wet carbonatation sludges, or sewage sludges or other wet wastes, considerable heat is formed, which vaporises the moisture of the sludges.

Description

Beschreibung:Description:

Verfahren zur Trocknung von Carbonatschlamm (Anfallprodukt der Zuckerindustrie - Zuckerfabriken) und Kläranlagenschlämme oder feuchte Anfälle.Process for drying carbonate sludge (by-product of the sugar industry - sugar factories) and sewage treatment sludge or wet seizures.

Die Carbonatschlämme bez. Kläranlagenschlämme oder feuchte Anfälle werden mit gebranntem Kalk im ungelöschten Zustand im Gemenge gebracht.The carbonate sludge or sewage treatment plant sludge or wet attacks are brought into the mixture with quick lime in the unslaked state.

Durch die Feuchtigkeit der Schlämme und Anfälle kommt der Kalk zum Reagieren.The lime comes to the through the moisture of the sludge and seizures React.

Die bei diesem Löschprozess entstehende erhebliche Wärme trocknet die Schlämme, indem sie den Feuchtigkeitsgehalt der Schlämme verdampft.The considerable heat generated during this extinguishing process dries up the sludge by evaporating the moisture content of the sludge.

Nach diesem Vorgang sind die Schlämme getrocknet und zum Mahlen, Walzen oder Absieben zu verwunden.After this process, the sludges are dried and ready for grinding, rolling wound or sieving.

Der Kalk vermengt sich mit dem getr~ckneten Material als bleibender Bestandteil.The lime mixes with the dried material as a permanent one Component.
