Description
Die Erfindung betrifft eine Vorrichtung zum Vergären von Biomasse zum Erzeugen von Gas mit einem von Erdreich und/oder einer Stützkonstruktion außen umgebenden Folienbehälter, dessen Oberseite durch ein Foliendach gasdicht verschlossen ist und in den ein Fütterungsrohr, ein Überlaufrohr und ein Gasentnahmerohr münden.The invention relates to a device for fermenting biomass for producing gas with a surrounding of soil and / or a supporting structure outside film container, the top is sealed gas-tight by a foil roof and open into a feeding tube, an overflow pipe and a gas sampling tube.
Es sind die unterschiedlichsten Biogasanlagen bekannt. Bei diesen bekannten Anlagen werden konstruktiv angepasste Spezialteile angefertigt und zusammengebaut. Wer eine solche Biogasanlage kleiner Abmessungen betreiben will, ist darauf angewiesen, verhältnismäßig teure Bauteile zu beziehen.There are a variety of biogas plants known. In these known systems constructionally adapted special parts are made and assembled. Who wants to operate such a biogas plant of small dimensions, is dependent on relatively expensive components to relate.
Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so zu verbessern, dass sie aus konstruktiv einfachen Teilen besteht, die überall preiswert zu erhalten sind, ohne auf die spezielle Anwendung angepasst sein zu müssen. Hierbei soll die Konstruktion einen schnellen und einfachen Aufbau ermöglichen, klein zusammenlegbar und leicht zu transportieren sein. Hierbei ist zu gewährleisten, dass eine optimale Durchmischung des Behälterinhalts ständig auf einfachste Weise ermöglicht wird.The object of the invention is to improve a device of the type mentioned so that it consists of structurally simple parts that are inexpensive to obtain everywhere, without having to be adapted to the specific application. Here, the construction should allow a quick and easy construction, small collapsible and easy to transport. It must be ensured that optimum mixing of the contents of the container is always made possible in the simplest way.
Diese Aufgaben werden erfindungsgemäß dadurch gelöst, dass die Behälterfolienwand und/oder das Foliendach von einem nach oben ragenden Rohr abgedichtet durchdrungen ist, in dem eine Stange als Stößel verschieblich einliegt, die nach oben aus dem Rohr als Griff oder mit einem Griff herausragt und an ihrem unteren, aus dem Rohr herausragenden Ende einen Mischkopf trägt.These objects are inventively achieved in that the container foil wall and / or the foil roof is penetrated sealed by an upwardly projecting tube in which a rod slidably rests as a plunger, which protrudes upwards out of the tube as a handle or with a handle and on her lower, protruding from the tube end carries a mixing head.
Eine solche Vorrichtung besteht konstruktiv aus einfachsten Teilen und ermöglicht einen schnellen, einfachen Aufbau. Die im Behälter befindliche Biomasse kann ständig ausreichend umgewälzt werden, so dass optimale Ergebnisse erzielt werden.Such a device is structurally made of the simplest parts and allows a quick, simple construction. The biomass in the tank can be constantly circulated sufficiently, so that optimum results are achieved.
Vorzugsweise wird vorgeschlagen, dass der Mischkopf von einer insbesondere Öffnungen aufweisenden Platte gebildet ist, die am Stangenende quer zur Stangenlängsachse befestigt ist. Um sicherzustellen, dass bei Abnahme von Gas der Druck im Behälter gleich bleibt, wird vorgeschlagen, dass das Foliendach durch Gewichte beschwert ist. Hierbei ist besonders vorteilhaft, wenn das Foliendach zur Aufnahme von Gewichten an seiner Oberseite Fächer, Taschen oder Befestigungsösen aufweist.Preferably, it is proposed that the mixing head is formed by a plate having in particular openings, which is fastened to the rod end transversely to the rod longitudinal axis. To ensure that the pressure in the container remains the same when gas is removed, it is proposed that the foil roof is weighted by weights. It is particularly advantageous if the foil roof for receiving weights on its upper side has compartments, pockets or eyelets.
Vorzugsweise wird vorgeschlagen, dass in dem Foliendach ein Öffnungsring eingeschweißt oder eingeklebt ist, der mit einem Deckel insbesondere einem Schraubdeckel verschlossen ist. Dabei kann im Deckel ein Schauglas angeordnet sein. Auch ist von Vorteil, wenn im Deckel das Gasentnahmerohr befestigt ist.Preferably, it is proposed that in the foil roof an opening ring is welded or glued, which is closed with a lid, in particular a screw cap. In this case, a sight glass can be arranged in the lid. It is also advantageous if the gas sampling tube is fastened in the lid.
Um bei drucklosem Behälter das Foliendach sicher oben zu halten, wird vorgeschlagen, dass über dem Foliendach eine Haltekonstruktion angeordnet ist, an der das Foliendach punktweise befestigt ist. Alternativ wird hierzu vorgeschlagen, dass das Foliendach durch mindestens eine im Behälter stehende Stange gehalten ist.In order to keep the foil roof securely up in the case of a pressureless container, it is proposed that a holding structure is arranged above the foil roof, to which the foil roof is fastened pointwise. Alternatively, it is proposed for this purpose that the foil roof is held by at least one standing in the container rod.
Um über den Außenrandbereich das Behälterinnere leicht und jederzeit erreichen zu können insbesondere den Behälter begehen zu können, wird vorgeschlagen, dass der Außenrand des Foliendachs mit dem oberen Folienrand des Behälters rundum verschweißt, verklebt und/oder verklammert ist, bis auf einen Außenrandbereich, an dem die Befestigung zwischen dem Foliendach und dem Behälterrand leicht lösbar und wieder dicht befestigbar ist. Hierbei ist von Vorteil, wenn die beiden Folien im lösbaren Außenrandbereich ineinander mindestens einmal umgeschlagen sind. Auch können die beiden Folien im lösbaren Außenrandbereich zwischen zwei Klemmleisten einliegen.In order to be able to reach the inside of the container easily and at any time, especially the container, it is proposed that the outer edge of the film roof is welded, glued and / or clamped to the upper film edge of the container, except for an outer edge region the attachment between the foil roof and the edge of the container is easily detached and again tightly fastened. It is advantageous if the two films in the detachable outer edge region are folded into each other at least once. Also, the two films einliegen in the detachable outer edge region between two terminal strips.
Alternativ kann der Außenrandbereich des Behälters umlaufend verschweißt und/oder verklebt sein und die Öffnung wird über einen Zugang realisiert, der vom Außenrandbereich in Richtung Behältermitte verläuft. Hierbei ist es von Vorteil, wenn die Öffnung derart gestaltet ist, dass die Folienenden der Öffnung so lang sind, dass ein dichter Verschluss möglich ist. Hierbei ist von Vorteil, wenn die beiden Folien mindestens einmal umgeschlagen sind. Auch können die beiden Folien in der lösbaren Naht zwischen zwei Klemmleisten einliegen.Alternatively, the outer edge region of the container may be circumferentially welded and / or glued and the opening is realized via an access which extends from the outer edge region in the direction of the container center. It is advantageous if the opening is designed such that the film ends of the opening are so long that a tight seal is possible. It is advantageous if the two films are handled at least once. Also, the two films can einliegen in the releasable seam between two terminal strips.
Vorzugsweise wird vorgeschlagen, dass das Überlaufrohr an tiefster Stelle am Behälter angeschlossen ist und in einem zweiten Behälter mündet, der die Gärreste aufnimmt. Auch ist von Vorteil, wenn das Fütterungsrohr unterhalb des Flüssigkeitsspiegels in den Behälter mündet.Preferably, it is proposed that the overflow pipe is connected at the lowest point on the container and opens into a second container which receives the digestate. It is also advantageous if the feeding tube opens below the liquid level into the container.
Besonders vorteilhaft ist es, wenn die Behälterfolienwand und das Foliendach aus Folienteilen zusammengesetzt sind, die ein Baukastensystem bilden zum Erstellen von Vergärvorrichtungen unterschiedlicher Formen und Größen.It is particularly advantageous if the container film wall and the film roof are composed of film parts which form a modular system for creating fermentation devices of different shapes and sizes.
