Description

Die Erfindung betrifft ein Verfahren zur Verwertung von Klärschlamm, welcher mit Kohle und ggf. Müll gemischt einem Entgasungsprozeß zur Erzeugung eines zwischenlager­ fähigen Brennstoffproduktes unterworfen wird, wobei der zugemischte Kohleanteil mehr als 10% beträgt.The invention relates to a method for recycling Sewage sludge, which is mixed with coal and possibly garbage a degassing process to produce an interim storage facility capable fuel product is subjected, the admixed coal content is more than 10%.

Durch die DE-OS 30 10 259 ist ein Verfahren zur Herstellung von Briketts aus organischen Produkten oder Abfallproduk­ ten bekannt, wobei durch Anreicherung, beispielsweise durch Kohle, die Einstellung eines höheren Brennwertes und kon­ stanten Heizwertes zur besseren Ausnutzung der in den orga­ nischen Produkten enthaltenen Heizwerte erreicht werden soll. Zur Durchführung dieses Verfahrens wird vorgeschla­ gen, daß in der Produktaufbereitung nach der Zerkleine­ rung und Magnetabscheidung eine Hygenisierung der Müll- und Klärschlammteile mittels pH-Wert-Verschiebung und Reibungswärme im Preßvorgang eine Erwärmung auf ca. 100- 120°C zur Erhaltung der Pasteurisierungstempera­ tur von ca. 70°C für die Dauer von 30 Minuten er­ reicht wird. Durch den sehr hohen Preßdruck und die Rei­ bungswärme mit exothermer Aufheizung soll sich eine Vor­ verschwelung der organischen Zellgewebe und Papiermole­ külgruppen ergeben, die durch die hohe Verdichtung eine chemisch-thermische Strukturveränderung erfahren sollen, welche im Preßling den CO-Gehalt und damit den Heizwert erhöhen soll.DE-OS 30 10 259 is a process for the production of briquettes from organic products or waste products ten known, by enrichment, for example by Coal, the setting of a higher calorific value and con constant calorific value for better utilization of the in the organization calorific values contained in products should. To perform this procedure, it is suggested gene that in the product preparation after the shredding and magnetic separation hygienization of waste and sewage sludge parts by means of pH shift and Frictional heat in the pressing process heats up to approx. 120 ° C to maintain the pasteurization temperature 70 ° C for 30 minutes is enough. Due to the very high pressure and the Rei Exercise heat with exothermic heating is said to be a pre carbonization of organic cell tissue and paper moles  result in cooling groups that have a high compression undergo chemical-thermal structural changes, which in the compact the CO content and thus the calorific value should increase.

Durch die DE-OS 28 33 731 ist ein Verfahren zur Herstellung von Briketts aus Kokskohle und festem organischem Müll bekannt sowie die Verwendung der Briketts als Beschickung bei einem Verfahren zur Heizgaserzeugung. Als ggf. vorge­ sehenes Bindemittel soll u. a. Klärschlamm Verwendung fin­ den. So ist beispielsweise der Einsatz von 50 Teilen Koks­ kohle, 50 Teilen Stadtmüll und 3 Teilen Klärschlamm ange­ geben.DE-OS 28 33 731 is a method for manufacturing of briquettes made from coking coal and solid organic waste known as well as the use of the briquettes as a feed in a process for generating hot gas. As pre-selected if necessary see binder should u. a. Sewage sludge use fin the. For example, the use of 50 parts of coke coal, 50 parts of municipal waste and 3 parts of sewage sludge give.

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, mit welchem eine wirtschaftliche Verwer­ tung von an sich schwer zu beseitigendem Klärschlamm mit vergleichsweise geringem Aufwand in umweltfreundlicher Weise möglich ist.The invention is based on this prior art the task is based on a method of the aforementioned Way of creating an economic waste treatment of sewage sludge, which is difficult to remove comparatively little effort in environmentally friendly Way is possible.

Erfindungsgemäß wird dies dadurch erreicht, daß die Kohle über 28% flüchtige Bestandteile aufweist und der Entga­ sungsprozeß unterhalb von 650°C durchgeführt wird. Beim Entgasungsprozeß werden die freiwerdenden, gasförmigen, übelriechenden Bestandteile des Klärschlamms mit den flüch­ tigen Bestandteilen der Kohle verbrannt. Der Klärschlamm wird somit zu einem nicht riechenden, zwischenlagerungs- und zündfähigen transportablen Koks weiter verarbeitet. Durch den Einsatz von Kohle mit einem hohen Anteil an flüchtigen Bestand­ teilen, also von nicht sehr wertvoller Kohle, wird der an sich nur schwer zu deponierende Klärschlamm zu einem umweltfreundlichen Verbrennungsprodukt umgestaltet, wel­ ches in den Heizmonaten oder in den Monaten, wo Energie­ bedarf anfällt, zur Verfügung steht.According to the invention this is achieved in that the coal Contains over 28% volatile components and the entga solution process is carried out below 650 ° C. During the degassing process, the released gaseous  malodorous components of the sewage sludge with the cursed components of the coal burned. The sewage sludge becomes a non-smelling, intermediate storage and ignitable transportable coke processed further. Through the use of coal with a high proportion of volatile stocks share, i.e. of not very valuable coal, the sewage sludge, which is difficult to deposit in itself remodeled environmentally friendly combustion product, wel ches in the heating months or in the months where energy needs arises, is available.

Vorteilhaft findet die beim Entgasungsprozeß freigesetzte Gasmenge zur Trocknung des Klärschlamms Verwendung.The one released during the degassing process is advantageous Use of gas to dry sewage sludge.
