Description
Die Erfindung betrifft ein Verfahren zum Erzeugen von Biogas nach dem Oberbegriff des Anspruchs 1 sowie eine Anlage zum Erzeugen von Biogas nach dem Oberbegriff des Anspruchs 5.The The invention relates to a method for producing biogas according to The preamble of claim 1 and a plant for generating biogas according to the preamble of claim 5.
Es ist bekannt, in Fermentierbehältern neben flüssigen Substraten, insbesondere Güllen aus unterschiedlichen Tierhaltungsbetrieben, feste Substrate zu verfaulen, um auch aus diesen Biogas zu gewinnen. Bei diesen festen Substraten, die auch Co-Substrate genannt werden, handelt es sich im allgemeinen um Festmist oder Silagen aus Mais, Getreide usw.. Die Umwandlung von festen organischen Substraten in Biogas gewinnt in jüngster Zeit auch zunehmende Bedeutung unter dem Gesichtspunkt der nachwachsenden Rohstoffe und erfährt eine entsprechende staatliche Förderung.It is known in fermentation tanks in addition to liquid Substrates, in particular gullies from different livestock farms, solid substrates too Rotten to win from these biogas. At these fixed Substrates, which are also called co-substrates, are generally for solid manure or silage from corn, cereals, etc. The conversion of solid organic substrates into biogas is gaining in the most recent Time also increasing importance from the point of view of the regrowing Raw materials and learns a corresponding state subsidy.

Bei den aus der Praxis bekannten Verfahren und Anlagen zur Biogasherstellung werden die flüssigen und festen Substrate in dem Fermentierbehälter selbst vermischt, wobei allenfalls eine gewisse Vorzerkleinerung der festen Substraten in Hackern oder ähnlichen Geräten stattfindet. Dies ermöglicht jedoch keine optimale Aufschließung der festen Substrate.in the known from practice methods and plants for biogas production be the liquid ones and solid substrates in the fermentation tank itself, wherein if necessary, some pre-crushing of the solid substrates in Hackers or similar devices takes place. this makes possible but no optimal opening the solid substrates.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bzw. eine Anlage der eingangs genannten Art anzugeben, mit denen insbesondere die festen Substrate vollständiger in Biogas umgewandelt werden können.task The present invention is a method of the type mentioned above, with which in particular the fixed Substrates more complete can be converted into biogas.
Diese Aufgabe wird, was das Verfahren angeht, durch die im Anspruch 1 angegebene Erfindung gelöst.These Task is, as far as the method is concerned, by the in claim 1 specified invention solved.
Erfindungsgemäß findet also die Vermischung von festen und flüssigen Substraten nicht im Fermentierbehälter selbst sondern in einer vorgeschalteten Behandlungsstufe statt, in der zusätzlich eine Zerkleinerung der festen Substrate erfolgt. Es entsteht auf diese Weise eine brei- oder musartige Masse, die in den Fermentierbehälter eingebracht und von den dort befindlichen Bakterien besser zersetzt werden kann, als dies bei her kömmlichen Fermentieranlagen der Fall war. Ergebnis ist eine vollständigere Aufschließung und Zersetzung insbesondere der festen Substrate bei einer entsprechend erhöhten Ausbeute an Biogas.According to the invention finds So the mixing of solid and liquid substrates not in Fermentierbehälter itself but in an upstream treatment stage, in the in addition one Comminution of the solid substrates takes place. It arises on this Way a brei- or musartige mass, which is introduced into the fermentation container and can be decomposed better by the bacteria located there, as this is conventional Fermenting plants was the case. Result is a more complete one digestion and decomposing, in particular, the solid substrates in a corresponding manner increased Yield of biogas.
Zweckmäßigerweise werden die festen Substrate vor dem Einmischen in die flüssigen Substrate aufgelockert. Hierdurch wird insbesondere erreicht, daß die festen Substrate nicht zusammengeballt auf den flüssigen Substraten aufschwimmen, sondern tatsächlich mit den flüssigen Substraten vermischt und dann in dieser Mischung zerkleinert werden können.Conveniently, The solid substrates are dissolved before mixing in the liquid substrates. As a result, it is achieved in particular that the solid substrates are not clenched on the liquid Floating substrates, but actually with the liquid substrates mixed and then crushed in this mixture.
Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens werden die flüssigen Substrate den festen Substraten so zudosiert, daß ein etwa konstanter Feststoffanteil eingehalten wird. Für jede Art von festen und flüssigen Substraten gibt es einen unter den vorliegenden Umständen experimentell zu ermittelnden optimalen Feststoffanteil, bei dem die Biogaserzeugung mit dem höchsten Wirkungsgrad abläuft.in a preferred embodiment the method according to the invention become the liquid substrates added to the solid substrates so that an approximately constant solids content is complied with. For every kind of solid and liquid Substrates exist experimentally under the circumstances to be determined optimal solids content, in which the biogas production with the highest Efficiency expires.
In vielen Fällen ist es günstig, wenn der Feststoffanteil bei etwa 25 Gewichtsprozent liegt.In many cases is it cheap when the solids content is about 25% by weight.
Die oben genannte Aufgabe wird, was die Anlage angeht, durch die im Anspruch 5 angegebene Erfindung gelöst.The The above object is, as far as the plant is concerned, by the Claim 5 specified invention solved.
Die Vorteile der erfindungsgemäßen Anlage entsprechen sinngemäß den oben geschilderten Vorteilen des erfindungsgemäßen Verfahrens. Auch die in den Ansprüchen 7 bis 10 angegebenen Ausführungsbeispiele der erfindungsgemäßen Anlage sind mit Vorteilen behaftet, die oben erwähnten Vorteilen des erfindungsgemäßen Verfahrens entsprechen.The Correspond to advantages of the system according to the invention mutatis mutandis the above described advantages of the method according to the invention. Also in the claims 7 to 10 specified embodiments the plant of the invention are associated with advantages that correspond to the above-mentioned advantages of the method according to the invention.
