Abstract
Description
Die Erfindung betrifft eine Biogasanlage zur Vergärung von feststoffreichem Material.The invention relates to a biogas plant for the fermentation of solid material.
Dadurch ist es möglich, sperriges oder aufschwimmendes Ma terial, selbst mit Fremdkörpern versehen, der Biogasanlage ohne Vorzerkleinerung unter Luftabschluß zuzuführen und zu vergären.This makes it possible to measure bulky or floating material, provided with foreign bodies, the biogas plant without pre-shredding and closing ferment.
Aus Umweltgründen ist es notwendig, organische Abfallstoffe zu entsorgen. Eine wirksame Methode ist dabei die anaerobe Vergärung. Für feststoffsicheres Material eignen sich die derzeit auf dem Markt befindlichen Biogasanlagen aber nicht. Der Grund liegt darin, daß das Material in der Regel so zerkleinert und mit Flüssigkeit verdünnt werden muß, damit es unter Luftabschluß in die Anlage gefördert werden kann. Speziell die Zerkleinerung von organischen Reststoffen, wie z. B. Grüngutabfälle, Festmist oder organischem Hausmüll erfordert einen hohen technischen Aufwand und ist wegen möglicher Fremdkörper mit Störungen behaftet.For environmental reasons it is necessary to use organic waste dispose. An effective method is anaerobic Fermentation. The are suitable for solid material But biogas plants currently on the market are not. The reason is that the material is usually like this crushed and diluted with liquid so that it can be conveyed into the system with the exclusion of air. Especially the crushing of organic residues, such as e.g. B. green waste, solid manure or organic household waste requires a lot of technical effort and is because possible foreign bodies with disturbances.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Bio gasanlage aufzuzeigen, die mit organischen Feststoffen ohne Vorzerkleinerung und Verdünnung problemlos unter Luftab schluß befüllt werden kann.The invention is therefore based on the object of a bio gas system to show that with organic solids without Pre-shredding and dilution without any problems under air can be filled in the end.
Die Aufgabe wird dadurch gelöst, indem das zu entsorgende Material über eine oder mehrere Rohrleitungen in den Fer menter eingepreßt (Fig. 1) oder Schnecken zugeführt wird.The object is achieved in that the material to be disposed of is pressed in via one or more pipes into the fermenter ( FIG. 1) or is supplied with screws.
Der Luftabschluß wird dadurch erreicht, indem der im Fer menter befindliche Flüssigkeitsstand als Vorlage höher als der Gasdruck im System ist. Beispielshaft kann dies durch die Höhe des Flüssigkeitsüberlaufes (Fig. 2) erfolgen. Die Flüssigkeit im Behälter dient zudem vorteilhaft als Medium für die Methanbakterien und zur Übertragung der not wendigen Prozeßwärme. Die Umspülung der Flüssigkeit erfolgt aus dem Flüssigkeitsschacht unterhalb des Siebbodens (Fig. 3) mittels einer Pumpe und wird auf das Feststoffsub strat aufgesprüht (Fig. 4). Die Aufheizung der Flüssig keit erfolgt im Flüssigkeitsschacht (Fig. 5).The exclusion of air is achieved in that the liquid level in the fermenter is higher than the gas pressure in the system. This can be done, for example, by the height of the liquid overflow ( FIG. 2). The liquid in the container also advantageously serves as a medium for the methane bacteria and for the transfer of the necessary process heat. The washing of the liquid takes place from the liquid shaft below the sieve bottom ( Fig. 3) by means of a pump and is sprayed onto the solid substrate ( Fig. 4). The heating of the liquid takes place in the liquid shaft ( Fig. 5).
Der Gasverschluß des Fermenters erfolgt über eine, in einer Wassertasse schwimmenden und vorteilhaft isolierten Gas haube (Fig. 6). Diese Vorrichtung bietet gleichzeitig eine wirksame Über- und Unterdrucksicherung.The gas lock of the fermenter takes place over a, in a water cup floating and advantageously insulated gas hood ( Fig. 6). This device also provides effective overpressure and underpressure protection.
Die Gasabnahme erfolgt z. B. über die in der Figur angedeu teten Gasleitung (Fig. 7).The gas take-off takes place e.g. B. via the indicated in the figure gas line ( Fig. 7).
Die Entnahme des ausgefaulten Substrats erfolgt nach Ende der gewünschten Vergärungszeit bei vorheriger Entfernung der Hau be mittels üblicher Entnahmetechnik, wie z. B. einem Greifer oder bei entsprechender Fermenterausführung einem Radlader.The digested substrate is removed after the end of the desired fermentation time with previous removal of the skin be using conventional removal technology, such as. B. a gripper or with a suitable fermenter version a wheel loader.
Ein wesentlicher Vorteil dieses Biogasanlagensystems ist, daß der Fermenter absätzig befüllt werden kann und bei min destens zwei Fermentern ein kontinuierlicher Betrieb ge währleistet ist.A major advantage of this biogas plant system is that the fermenter can be filled to a minimum and at min at least two fermenters ge continuous operation is guaranteed.
