Abstract
Description
System zum Bau von Biogasalagen mit liegendem BehälterSystem for the construction of biogas plants with a horizontal tank
aus Betonfertigteilen.made of precast concrete parts.
Biogasanlagen bestehen aus einem Behälter in den die auszufaulende Biomasse unter Sauerstoff- und Lichtausschluß eingebracht wird,so daß unter Zuführung von Wärme die anaerobe Fermentation und Methanbildung stattfinden kann.Biogas plants consist of a container in which the to be digested Biomass is introduced with exclusion of oxygen and light, so that under supply from heat the anaerobic fermentation and methane formation can take place.
Das Verfahren der Methangewinnung aus Biomasse ist hinreichend bekannt und in der Literatur umfangreich beschrieben.Die Behälter können danach in liegender oder stehender Ausführung in Metall,Kunststoff,Mauerwerk oder Beton gebaut werden.Beton hat den Vorteil,daß es keine Festigkeits-und Korrosionsprobleme gibt.Nachteile dagegen sind teure Ortbetonkonstruktionen,schwierige Abdichtung des Gasraumes und Isolationsprobleme.The process of methane production from biomass is well known and extensively described in the literature. The containers can then be placed horizontally or standing design in metal, plastic, masonry or concrete. Concrete has the advantage that there are no strength or corrosion problems. Disadvantages on the other hand are expensive in-situ concrete structures, difficult sealing of the gas space and insulation problems.
Aufgabe der vorliegenden Erfindung ist es ein System von Bauelementen darzustellen,die es erlauben,daß sie in standardisierten Größen vorgefertigt werden und einfach sowie gasdicht am Aufstellungsort zusammengesetzt werden können.The object of the present invention is a system of components that allow them to be prefabricated in standardized sizes and can be assembled easily and gas-tight at the installation site.
Die Aufgabe wird erfindungsgemäß so gelöst,daß der Behälter in eine Wanne und in eine oder mehrere haubenförmige Abdeckungen unterteilt wird.Der Behälter hat eine liegende Form.Die Wanne kann aus mehreren unmittelbar in Außenformen aus Isoliermaterial vergossenen Fertigbetonelementen bestehen,die am Aufstellungsort miteinander verbunden und abgedichtet gegen Wasser werden oder es können vor Ort die vorgefertigten Außenformen aus Isoliermaterial mit Beton ausgegossen werden,so daß eine homogene Wanne entsteht.Die Abdeckungen können in gleicher Weise in Außenformen aus Isoliermaterial geossen werden oder als Fertigelement nach Montage isoliert werden.Die Abdeckungen sind so gestaltet, daß sie einen nach unten offenen Hohlraum bilden,der mit einem gasdichten Anstrich vor Montage versehen wird.Erfindungsgemäß werden die Abdeckungen so in die Wanne eingestellt, daß sich der untere Rand der Abdeckungen immer unterhalb des Flüssigkeitsspiegels befindet und sich somit eine natürliche Abdichtung des Gasraumes durch die Flüssigkeit ergibt.The object is achieved so that the container in a Tub and divided into one or more hood-shaped covers. The container has a horizontal shape. The tub can be made up of several directly into external shapes Insulating material cast precast concrete elements exist at the place of installation can be connected to each other and sealed against water or it can be on site the prefabricated outer forms made of insulating material are poured with concrete, so that a homogeneous tub is created. The covers can be shaped in the same way can be cast from insulating material or isolated as a prefabricated element after assembly The covers are designed so that they have a downwardly open cavity Form, which is provided with a gas-tight coating before assembly. According to the invention the covers are placed in the tub in such a way that that the The lower edge of the covers is always below the liquid level and this results in a natural sealing of the gas space by the liquid.
Die Erfindung wird an einem möglichen Ausführungsbeispiel zeichnerich dargestellt und weiter erläutert.Es zeigen: Fig.l Gesamtsystem im Längsschnitt Fig.2 Gesamtsystem im Querschnitt Fig.3 Teildraufsicht Die auf der Wanne (1) befindlichen haubenförmigen Abdeckungen (2-) werden erfindungsgemäß vorzugsweise in Hutform ausgeführt.Die Gasräume sind mittels Kanälen,vorzugsweise Rohren (3) miteinander verbunden.Durch Einbringen von Ventilen (4) in diesen Kanälen,kann der Gasdruck in den einzelnen Gasräumen variiert werden.Die Abdeckungen haben alle die gleiche Form.Die Außenformen der Wanne aus Isoliermaterial (5) bestehen aus zwei gleichen Endstücken und einem oder mehreren gleichen Mittelstücken.Gleiches gilt auch für die Betonfertigteile der Wanne.The invention is illustrated using a possible exemplary embodiment shown and further explained. It shows: Fig.l overall system in longitudinal section Fig.2 Overall system in cross-section Fig. 3 Partial plan view The ones on the tub (1) Dome-shaped covers (2-) are preferably designed according to the invention in the shape of a hat Gas spaces are connected to one another by means of channels, preferably pipes (3) Introducing valves (4) in these channels, the gas pressure in the individual Gas compartments can be varied. The covers all have the same shape. The outer shapes the tub made of insulating material (5) consist of two identical end pieces and one or several identical middle pieces. The same applies to the precast concrete parts the tub.
Der Antrieb (6) für das Rührwerk (7),das zur Vermeidung von Schwimmdecken und Sedimentationen erforderlich ist,ist erfindungsgemäß so gestaltet,daß der Getriebemotor über eine, in das Substrat eintauchende Kette (8) das Rührwerk bewegt.The drive (6) for the agitator (7), which is used to avoid floating ceilings and sedimentation is required, is designed according to the invention so that the gear motor The agitator is moved by a chain (8) dipping into the substrate.
Bei größeren Anlagen,können an beiden Anlagenenden Antriebe sein.Die Rührwerkwellen können dann getrennt sein,wobei die freien Wellenenden ein gemeinsames Auflager haben können (9).In the case of larger systems, there can be drives at both ends of the system Agitator shafts can then be separate, with the free shaft ends sharing a common one May have supports (9).
Die Abdeckungen können auch aus Metall,vornehmlich Stahl,oder Kunststoff gefertigt sein.Sie können zur Aufnahme von Nutzlasten gestaltet sein.Gleiches gilt für den hochgezogenen Wannenrand (l-O).Der Wannenquerschnitt kann rund (ll),oval(12) oder ausgebuchtet sein um Wärmetauscher (13) aufzunehmen.The covers can also be made of metal, mainly steel, or plastic They can be designed to accommodate payloads. The same applies for the raised tub rim (l-O). The tub cross-section can be round (ll), oval (12) or be bulged to accommodate the heat exchanger (13).
Die Abdichtung von Ein- und Auslauf gegenüber dem Wannenrand erfolgt durch je zwei Trennwände die bei Montage eingesetzt werden (14).The inlet and outlet are sealed against the edge of the tub with two partitions each that are used during assembly (14).
