Abstract
Description
Die Erfindung betrifft einen Reaktor zur Erzeugung von Biogas aus Gülle nach dem Oberbegriff des Patentanspruches.The invention relates to a reactor for generating Biogas from manure according to the preamble of the claim.
Bei der Erzeugung von Biogas aus Gülle ist die Durch mischung der Gülle in dem Behälter erforderlich, da sich anderenfalls eine Schwimmdecke bildet und orga nische Substanz dem Gärprozeß entzogen wird.When producing biogas from liquid manure, the through is Mixing the manure in the container is necessary because otherwise a floating blanket forms and orga niche substance is removed from the fermentation process.
Aus der Zeitschrift "Technik am Bau", 8/1981, S. 667 f. ist ein gattungsgemäßer Reaktor zur Erzeugung von Bio gas aus Gülle bekannt. Dabei besteht die Rührvorrich tung aus einer durch die Mittelachse des zylindrischen Behälters verlaufenden Welle und darauf mit Abstand von einander aufgesetzten Zinkenrädern. Bei Antrieb der Welle werden die Zinkenräder in dem Behälter gedreht, so daß im unteren Bereich des Behälters befindliche Gülle nach oben geführt und oben befindliche Gülle nach unten geführt wird. Bei einem derartigen Betreiben der Rührwerke ist aber nicht möglich, Gülle von dem vorde ren Bereich des Behälters in den hinteren Bereich des Behälters zu bringen. Vielmehr wird sich im vorderen Bereich des Behälters im wesentlichen frisch einge führte Gülle befinden, während im hinteren Bereich des Behälters sich im wesentlichen bereits weitgehend ver gorene Gülle ablagert. Weiter ist eine ausreichende Steuerung des Gärprozesses mittels der bekannten Rühr werke nicht möglich. Auch ist eine automatische Reini gung der Rührwerke bei der bekannten Ausgestaltung nicht möglich.From the magazine "Technik am Bau", 8/1981, p. 667 f. is a generic reactor for the production of bio gas known from manure. There is the mixer tion from a through the central axis of the cylindrical Container running shaft and on it at a distance of tine wheels placed one on top of the other. When driving the The tine wheels are rotated in the container, so that located in the lower part of the container Liquid manure led upwards and liquid manure above is led below. In such an operation Agitators are not possible, manure from the front ren area of the container in the rear area of the Bring container. Rather, it will be in the front Area of the container essentially freshly turned on led manure while located in the rear of the Container is already largely ver Gorene slurry deposits. Next is sufficient Control of the fermentation process using the well-known stirrer works not possible. There is also an automatic reini supply of the agitators in the known embodiment not possible.
Der Erfindung liegt die Aufgabe zugrunde, in einem Reaktor der eingangs genannten Art bei zumindest teilweiser Entmi schung der Gülle ein zuverlässiges Austragen der Fest bestandteile zu gewährleisten.The invention is based, in a reactor type mentioned at the beginning with at least partial entmi the manure ensures reliable discharge of the solid to ensure components.
Diese Aufgabe wird durch die Kombination der im Patentanspruch aufgeführten Merkmale gelöst.This task is accomplished by the combination of those listed in the claim Features solved.
Ein Ausführungsbeispiel nach der Erfindung wird in der folgenden Beschreibung anhand der Zeichnung näher erläutert.An embodiment according to the invention is in the following description with reference to the drawing explained.
Diese zeigt einen Längsschnitt durch den erfindungsgemäßen Behälter.This shows a longitudinal section through the container according to the invention.
10 verdeutlicht einen liegenden zylindrischen Behälter, an dessen Längsseite in Wassertaschen 16 eine Rohrlei tung 18 verläuft. In diesen mit einem Schieber 56 versehenen Zulauf 58 wird die zu vergärende Gülle ein geführt. 10 illustrates a lying cylindrical container, on the long side in water pockets 16, a pipe 18 runs. In this provided with a slide 56 inlet 58 , the manure to be fermented is a.
Die Zeichnung zeigt weiter ein an einem der Endstücke des Behälters 10 angeflanschten unteren Gülleablauf 36, welcher mit einem Schieber 34 versehen ist und einen Teil eines Gülleauslaufs 32 bildet. Im Behälter 10 liegt vor dem Anschluß dieses Gülleablaufes 36 ein Abweisblech 52, hinter dem sich in der Gülle befindli che Sinkteile ablagern, die zuvor vom Rührwerk bzw. von den Zinken über das Abweisblech 52 geschoben wurden und sodann durch den Gülleablauf 36 herausgedrückt werden.The drawing further shows a lower slurry outlet 36 flanged to one of the end pieces of the container 10 , which is provided with a slide 34 and forms part of a slurry outlet 32 . In the container 10 is before the connection of this manure drain 36, a baffle 52 , behind which are in the manure in the manure sinking parts that were previously pushed by the agitator or by the tines over the baffle plate 52 and then pushed out by the manure drain 36 .
Der Gülleauslauf 32 weist weiter einen oberen Gülleab lauf 36′ auf, welcher im oberen Bereich des Endstücks des Behälters 10 angeflanscht und mit einem Schieber 62 versehen ist. Hinter einem Abweisblech 54 sammeln sich Schwimmteile, die zuvor vom Rührwerk bzw. von dem Zin ken hinter das Abweisblech geschoben wurde, welche mit der abfließenden Gülle durch den Gülleabfluß 36′ ab fließen. The slurry outlet 32 further has an upper slurry outlet 36 ' , which is flanged in the upper region of the end piece of the container 10 and is provided with a slide 62 . Behind a baffle plate 54 floating parts that were previously pushed by the agitator or the Zin ken behind the baffle plate, which flow with the draining slurry through the slurry drain 36 ' .
In dem Behälter sind in gewissen Abständen quer zu dessen Längsachse ausgerichtete, in einer Behälterwand 12 mittels einer drehbar gelagerten Welle 38 versehene, Rührwerke 40, 40′ vorgesehen.In the container are aligned at certain intervals transversely to its longitudinal axis, provided in a container wall 12 by means of a rotatably mounted shaft 38 , agitators 40, 40 ' .
Mittels des erfindungsgemäßen Reaktors wird nicht nur Biogas gewonnen, sondern auch der Düngewert dieser Gülle verbessert. Während nämlich frische Gülle einen pH-Wert von etwa 6,5 aufweist, also relativ sauer ist, liegt die in dem erfindungsgemäßen Reaktor umgesetzte Gülle in einem Bereich mit einem pH-Wert von etwa 8, ist also leicht alkalisch. Sämtliche Nährstoffe werden durch den biologischen Vorgang aufgeschlossen und den Pflanzen voll zur Verfügung gestellt, so daß der Dünge wert der Gülle deutlich verbessert wird und keine Ätzwirkung entsteht.By means of the reactor according to the invention not only Biogas won, but also the fertilizer value of this Manure improved. While fresh manure has a pH of around 6.5, i.e. is relatively acidic, lies the converted in the reactor according to the invention Manure in a range with a pH of about 8, is slightly alkaline. All nutrients are unlocked by the biological process and the Plants fully provided so that the fertilizer manure is significantly improved and none Corrosivity occurs.
