Description

Die Erfindung betrifft einen garagenförmigen Fermenter mit optimierten Bauelementen zur Methanisierung von Biomasse im Batch-Verfahren.The The invention relates to a garage-shaped fermenter with optimized Components for the methanation of biomass in a batch process.

Vorbekannt sind ein Trockenfermentationsverfahren nach EP 09349981 A2 zur Methanisierung von halbfeuchter, schüttfähiger, stapelbarer oder stückigmachbarer, inokulierter Biomasse sowie ein garagenförmiger Bioreaktor der Fa. Bekon/Landshut. Ein weiterer garagenförmiger Fermenter ist aus der EP 023176 A2 bekannt. Dieser Fermenter weist bodenseitig einen Gitterrost auf, auf dem die Biomasse ruht. In funktionaler Hinsicht ist hieran nachteilig, dass eine hohen Hygieneanforderungen genügende Reinigung des Fermenters nur mit erheblichem Aufwand möglich ist.Previously known are a Trockenfermentationsverfahren after EP 09349981 A2 for the methanation of semi-moist, free-flowing, stackable or unitized, inoculated biomass and a garage-shaped bioreactor from Bekon / Landshut. Another garage-shaped fermenter is from the EP 023176 A2 known. This fermenter has on the bottom side a grid on which rests the biomass. In functional terms, this is disadvantageous that a high hygiene requirements sufficient cleaning of the fermenter is possible only with considerable effort.

Die als DE 100 34 279 A1 nachveröffentlichte ältere Anmeldung offenbart einen garagenförmigen Fermenter, dessen Boden ein zum Tor hin geneigtes Gefälle aufweist, wobei in dem Fermenterboden zumindest eine nahe zum Tor angeordnete Ablaufrinne vorgesehen ist.As DE 100 34 279 A1 nachveröffentlichte older application discloses a garage-shaped fermenter, the bottom of which has a slope inclined towards the gate, wherein in the fermenter bottom at least one arranged close to the gate gutter is provided.

Es ist Aufgabe der vorliegenden Erfindung, die oben genannten, bereits bekannten Erfindungen in sicherheitstechnischer und funktionaler Sicht wesentlich zu verbessern.It Object of the present invention, the above, already known inventions in safety and functional Significantly improve vision.

Bei der vorgestellten Erfindung handelt es sich um einen garagenförmigen Fermenter in Modulbauweise, bei welchem der Fermenterboden (1) im Gegensatz zur vorbekannten Ausführung in Richtung rückwärtige Wand (2) ein Gefälle aufweist. Durch diese Ausführungsform wird verhindert, dass im Sinne einer Gleitschichtbildung Biomasse in Richtung auf das Tor (3) wandert und so unbeherrschbare statische Belastungen und Unfallgefahren des Tores entstehen.The presented invention is a modular fermentor-shaped fermenter in which the fermenter bottom ( 1 ) in contrast to the previously known embodiment in the direction of the rear wall ( 2 ) has a slope. By means of this embodiment, it is prevented that biomass in the direction of the gate ( 3 ) and so uncontrollable static loads and accident hazards of the gate arise.

Eine weitere Besonderheit stellt eine zusätzliche mittige Ablaufrinne (4) dar, die so im Fermenterboden eingesetzt ist, dass beiderseits sich ein Gefälle zur Mitte ergibt. Eine derartige Anordnung bringt den Vorteil einer zentralen Perkolatentsorgung und einer Schubentlastung für die Seitenwände.Another special feature is an additional central gutter ( 4 ), which is inserted in the fermenter bottom so that on both sides there is a gradient to the center. Such an arrangement provides the advantage of central percolate removal and thrust relief for the sidewalls.

In der vorbekannten Erfindung wird Abgas eines Verbrennungsmotors zum Fluten des geschlossenen Fermenters verwendet und das Öffnen geschieht erst, wenn eine Sauerstoffsonde die völlige Sauerstofffreiheit signalisiert. In der vorliegenden Erfindung wird über ein leistungsfähiges, zeitgesteuertes Sauggebläse (5) an der rückwertigen Wand das Methangas/CO2-Gemisch während der Vorbereitungs- und Entleerungsphase des Fermenters abgesaugt und gleichzeitig strömt über eine ausreichend dimensionierte Luftöffnung (6) Frischluft nach. Diese Anordnung bringt den Vorteil, auf eine Sauerstoffsensorik verzichten und die Entleerungsarbeiten stets in einem optimalen abgasarmen Milieu durchführen zu können.In the prior art invention exhaust gas of an internal combustion engine is used to flood the closed fermenter and the opening occurs only when an oxygen probe signals the complete oxygen freedom. In the present invention, a powerful, time-controlled suction fan ( 5 ) sucked off the methane gas / CO2 mixture during the preparation and emptying phase of the fermenter at the rear wall and at the same time flows over a sufficiently dimensioned air opening ( 6 ) Fresh air after. This arrangement has the advantage of dispense with an oxygen sensor and perform the emptying work always in an optimal low-emission environment.

In der vorbekannten Ausführung werden die Spülgase direkt in die Atmosphäre abgegeben, während in der vorliegenden Erfindung diese einen Biofilter (7) passieren müssen, um Geruchsemissionen zu reduzieren.In the previously known embodiment, the purge gases are discharged directly into the atmosphere, while in the present invention, these a biofilter ( 7 ) have to pass to reduce odor emissions.

In der vorbekannten Erfindung wird der Gasverbraucher Biogasdruck-gesteuert betrieben, so daß auf einen eigenen Gasspeicher verzichtet wird. Die vorliegende Erfindung bedient sich eines Seitendruckverdichters (Sauggebläse) (5), welcher das Biogas aus dem Fermenter absaugt und in einen eigenen Druckspeicher (8) einpumpt. Nach Überschreiten eines einstellbaren Überdrucks kann Reservegas in einem herkömmlichen Folienspeicher (9) zwischengelagert werden. Durch den entstehenden Unterdruck im Fermenter kann die experimentell bei Unterdruck nachgewiesene erhöhte Methanproduktion genutzt werden und durch die gleichmäßige Druckbeaufschlagung des BHKW (10) die Lebensdauer des Motors verbessert werden.In the prior art invention, the gas consumer biogas pressure-operated, so that is dispensed with a separate gas storage. The present invention uses a side pressure compressor (suction fan) ( 5 ), which sucks the biogas from the fermenter and into its own pressure accumulator ( 8th ). After an adjustable overpressure has been exceeded, reserve gas can be stored in a conventional film store ( 9 ) be stored. Due to the resulting negative pressure in the fermenter, the experimentally proven at negative pressure increased methane production can be used and by the uniform pressurization of the CHP ( 10 ) the life of the engine can be improved.

Während die vorbekannte Erfindung keine Möglichkeit zur Einspeisung von Cofermenten vorsieht, ist in der vorliegenden Erfindung eine externe Einspeisemöglichkeit (11) verflüssigungsfähiger Cofermente vorgesehen. Die Vorrichtung ist auch dahin erweiterungsfähig, daß spezielle Zerkleinerungs- und Vermusungswerkzeuge (12) die Cofermente nutzungsgerecht aufbereiten. Der aufbereitete Cofermentstrom wird direkt in den rezirkulierten Perkolatstrom eingespeist und somit über die gesamte Oberfläche der Biomasse verteilt.While the prior art invention does not provide for the possibility of feeding in co-oxygenates, in the present invention an external feed-in option (US Pat. 11 ) liquefiable Cofermente provided. The device is also expandable to the extent that special shredding and grinder tools ( 12 ) prepare the coferments in accordance with their intended use. The treated coferment stream is fed directly into the recirculated percolate stream and thus distributed over the entire surface of the biomass.
