Description

Keramische Pellets und Herstellungsverfahren Ceramic pellets and manufacturing process

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von kerami-schen Pellets sowie die nach dem Verfahren hergestellten Pellets.The present invention relates to a method for producing ceramic pellets as well as the pellets produced by the process.

Aus der DE-OS 16 4o 574 ist ein poröses keramisches Material bekannt, das aus einem gebrannten Gemenge eines - Lehm- oder Tonmaterials und - Klärschlamm oder Müll- und Kehrichtverbrennungsschlacken besteht.From DE-OS 16 4o 574 a porous ceramic material is known, that from a burned mixture of - clay or clay material and - sewage sludge or waste and garbage incineration slag.

Erfindungsgemäß wurde nun überraschenderweise f-estgestellt, daß man auch dann ein vielfältig verwendbares poröses keramisches Material erhalten kann, wenn man (a) Klärschlamm - mit Industriestaub oder - mit Industriestaub und einem hydraulischen Bindemittel oder einer Komponente mischt, die mit dem Industriestaub ein hydraulisches Bindemittel bildet, (b) die resultierende Masse pelletisiert und (c) die gebildeten Pellets brennt.According to the invention it has now surprisingly been found that one a porous ceramic material that can be used in a variety of ways can then also be obtained, if you (a) sewage sludge - with industrial dust or - with industrial dust and a hydraulic binder or component that mixes with the industrial dust forms a hydraulic binder, (b) pelletizing the resulting mass and (c) the formed pellets burns.

Der Fachmann ist mit dem Pelletisieren und dem Brennen von Pellets vertraut; beispielsweise sei nur auf den angeführten Stand der Technik verwiesen. Seim Pelletisieren kann Klärschlamm in Abhängigkeit von seinem Wassergehalt nicht mit beliebigen engen an Industriestaub oder tndustriestaub mit hydraulischem Bindemittel bzw. Komponente des hydraulischen Bindemittels versetzt werden; ein Grenzwert ist dann erreicht, wenn der geringe Feuchtigkeitsgehalt der resultierenden Masse eine Pelletisierung nicht mehr zuläßt.Those skilled in the art are familiar with pelletizing and burning pellets trusted; for example, only refer to the one listed State of Technology referenced. Seim pelletizing can sewage sludge depending on its Water content not having any close to industrial dust or industrial dust added hydraulic binder or component of the hydraulic binder will; a limit value is reached when the low moisture content of the resulting mass no longer allows pelletization.

Man kann z.B. bei 800 bis t500 OC brennen, wobei sich bei dioxinhaltigen Industriestäuben Temperaturen ab 1150 oder 1200 °C eignen.For example, one can burn at 800 to t500 OC, whereby dioxin-containing Industrial dust temperatures from 1150 or 1200 ° C are suitable.

Erfindungsgemäß kann man als Industriestaub Flugasche oder Elektrofilterstaub verwenden, insbesondere Flugasche aus Kohle- oder Müllverbrennungsanlagen. Als hydraulisches Bindemittel oder als dessen Komponente eignen sich Ton oder Tonerde.According to the invention, fly ash or electrostatic precipitator dust can be used as industrial dust use, especially fly ash from coal or garbage incinerators. As a hydraulic Suitable binders or as a component thereof are clay or alumina.

Der Wassergehalt des in das erfindungsgemäße Verfahren einzusetzenden Klärschlamms kann im Bereich von 50 bis 85, insbesondere 60 bis 80 und vorzugsweise 65 bis 75 Gew.-% liegen.The water content to be used in the process according to the invention Sewage sludge can range from 50 to 85, especially 60 to 80 and preferably 65 to 75% by weight.

Im folgenden werden 3eispiele für Rezepturen angegeben: Beispiel 1 Gewichtsteile Klärschlamm (50 bis 90 Gew.-% Wasser) 100 Industriestaub bis 300 Beispiel 2 Klärschlamm (50 bis 90 Gew.-% Wasser) 100 Industriestaub 300 bis 100 hydraulisches Bindemittel oder dessen Komponente 1 bis 200 Die erfindungsgemäßen keramischen Pellets eignen sich wegen ihrer Porosität und ihrer mechanischen Festigkeit hervorragend zur Schall- und Wärmedämmung.In the following 3 examples for recipes are given: Example 1 Parts by weight of sewage sludge (50 to 90% by weight of water) 100 industrial dust to 300 example 2 sewage sludge (50 to 90% by weight water) 100 industrial dust 300 to 100 hydraulic Binder or its component 1 to 200 The invention ceramic pellets are suitable because of their porosity and mechanical strength excellent for sound and heat insulation.

Beispiel 1 Es wurden 100 kg Klärschlamm einer oberbayerischen städtischen Zentralkläranlage eingesetzt. Die Trockensubstanz machte 11,9 % und die organische Substanz 40,9 °x0 aus. Dazu wurden 100 kg Flugasche aus einer städtischen Müllverbr&rinung und 10 kg Kaolintonerde aus der Oberpfalz gegeben.Example 1 There were 100 kg of sewage sludge from an Upper Bavarian urban Central sewage treatment plant used. The dry matter made 11.9% and the organic Substance 40.9 ° x0. For this purpose, 100 kg of fly ash from a municipal waste incineration plant were used and 10 kg of kaolin clay from the Upper Palatinate.

Der Gehalt der Flugasche an bestimmten Elementen war wie folgt (mg/kg): As 73, Cd 415, Cr 492, Hg 1,3, Ni 119, Pb 9, Se 15, V 61, Tl 1, Be 2, Te # 5 und Ca 800. Für die Kaolintonerde ergab sich folgende Analyse (%): Glühverlust ca. 13, SiO2 51, Al2O3 mit rio2 und P205 ca. 30, Fe2O3 ca. 4, CaO ca: 1 und MgO ca. 0,3.The content of certain elements in the fly ash was as follows (mg / kg): As 73, Cd 415, Cr 492, Hg 1.3, Ni 119, Pb 9, Se 15, V 61, Tl 1, Be 2, Te # 5 and Approx. 800. The following analysis (%) resulted for the kaolin clay: loss on ignition approx. 13, SiO2 51, Al2O3 with rio2 and P205 approx. 30, Fe2O3 approx. 4, CaO approx: 1 and MgO approx. 0.3.

Zum Pelletisieren verwendete man eine Pelletisiertrommel mit einem Durchmesser von 1 m. Die erhaltenen Pellets wurden bei einer Temperatur von etwa 1200 °C gebrannt und eigneten sich vorzüglich zur Wärme- und Schallisoliérung in Bauwerken.A pelletizing drum with a was used for pelletizing Diameter of 1 m. The pellets obtained were at a temperature of about 1200 ° C and are ideal for thermal and acoustic insulation in Structures.

Bei einem weiteren gleichguten Versuch betrug abweichend die Trockensubstanz des Klärschlamms 25 °zO und die organische Substanz 80 %.In another equally good test, the dry matter was different of the sewage sludge 25 ° zO and the organic matter 80%.
