Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Gewinnung von Biogas aus organischen Feststoffen gemäß dem Oberbegriff des Patentanspruchs 1 (
Vorrichtungen zur anaeroben Behandlung von Abwasser und anderen Gemischen aus einer Flüssigkeit und Feststoffen sowie entsprechende Verfahren haben in den letzten Jahren zunehmend an Bedeutung gewonnen, da sie die in dem zu behandelnden Medium enthaltenen organischen Substanzen im wesentlichen zu nutzbarem Biogas umsetzen und relativ wenig an überschüssiger Biomasse erzeugen. Außerdem entfällt die bei aeroben Verfahren notwendige Belüftung. Wegen einer hohen spezifischen Feststoffbelastung werden nur geringe Reaktorvolumina benötigt und es können Reaktoren mit schlanker Bauart und entsprechend geringem Platzbedarf eingesetzt werden. Als Reaktoren werden dabei Behälter aus Metall, Kunststoff oder Beton verwendet.Devices for the anaerobic treatment of waste water and other mixtures of a liquid and solids and corresponding methods have become increasingly important in recent years, as they convert the organic substances contained in the medium to be treated substantially to usable biogas and relatively little of excess biomass produce. In addition, eliminates the need for aerobic process ventilation. Because of a high specific solids loading only small reactor volumes are needed and it can be used reactors with a slim design and correspondingly small footprint. As reactors while containers made of metal, plastic or concrete are used.

Die bekannte Vorrichtung nach der eingangs erwähnten
Der Erfindung liegt die Aufgabe zugrunde, den Wirkungsgrad der eingangs geschilderten Vorrichtung zu verbessern.The invention has for its object to improve the efficiency of the above-described device.
Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved according to the characterizing features of
Der mit dieser Vorrichtung zu behandelnde organische Feststoff wird nach einer geeigneten Vorbehandlung, zu der auch eine Zerkleinerung gehören kann, einem aus dem Reaktor abgezogenen Flüssigkeit-Feststoff-Gemisch zugegeben und dem Reaktor mittels der Pumpe über die Rohrleitung und die Düse zugeführt. Das den organischen Feststoff enthaltende Gemisch gelangt damit direkt in das zentrale Umlaufrohr des Reaktors und wird durch dasselbe und um dasselbe herum im Reaktor im Kreislauf bewegt. Infolge des Impulses des aus der Düse austretenden Flüssigkeit-Feststoff-Gemisches wird das dem Umlaufrohr und damit dem Reaktor zugeführte Gemisch mit dem Reaktorinhalt intensiv vermischt. Es wird zusätzlich durch das zwischen dem Unlaufrohr und der Wandung des Reaktors angeordnete Lochblech mit dem Ergebnis durchmischt, daß die im Reaktor befindlichen Mikroorganismen immer wieder in engen Kontakt mit dem Feststoff gebracht werden. Dadurch wird die Kontaktfläche zwischen den Mikroorganismen und dem Feststoff vergrößert und stetig erneuert. Die Abtrennung des durch die anaerobe biologische Reaktion entstehenden Biogases wird insgesamt verbessert und es wird eine erhöhte Menge an Biogas erzielt.The organic solid to be treated with this apparatus is, after a suitable pretreatment, which may include comminution, added to a liquid-solid mixture withdrawn from the reactor and fed to the reactor by means of the pump via the pipe and the nozzle. The mixture containing the organic solid thus passes directly into the central circulation pipe of the reactor and is circulated through it and around it in the reactor. As a result of the pulse of the liquid-solid mixture emerging from the nozzle, the mixture supplied to the circulation pipe and thus to the reactor is intensively mixed with the reactor contents. It is additionally mixed by the arranged between the flow tube and the wall of the reactor perforated plate with the result that the microorganisms in the reactor are always brought into close contact with the solid. As a result, the contact area between the microorganisms and the solid is increased and constantly renewed. The separation of biogas produced by the anaerobic biological reaction is improved overall and an increased amount of biogas is achieved.
Als Feststoffe können z. B. landwirtschaftliche Produkte, wie Mais, Getreide oder Rüben, aber auch organische Abfälle, wie Klärschlamm, Speisereste usw., oder Gemische aus diesen Materialien eingesetzt werden.As solids z. As agricultural products such as corn, cereals or beets, but also organic waste, such as sewage sludge, food particles, etc., or mixtures of these materials are used.
