Description

Vorrichtung zur Methanisierung von Substraten unterschiedlicher Konsistenz in einem kontinuierlich bzw. semikontinuierlich arbeitenden Gleitschicht-FermenterDevice for methanation of substrates of different consistencies in a continuously or semi-continuously operating sliding layer fermenter

BeschreibungDescription

Zur Biogasgewinnung werden methanisierbare Biomassen (z. B. Gülle oder Klärschlämme) entweder in flüssiger Form (Flüssig-Vergärung) oder in halbfeuchter Form (Trocken-Vergärung) in Fermentern mikrobiologisch genutzt. Die im landwirtschaftlichen oder kommunalen Bereich favorisierte Flüsssig-Vergärung von Gülle oder Klärschlamm ist vorwiegend auf deren betriebsinterne Verwertung abgestellt. Wegen der geringen Energiedichte z. B. der Gülle lohnt sich kein Transport, was im Regelfall durch die Größe dieser Anlagen deren Wirtschaftlichkeit begrenzt. Andererseits müssen ausbeutungswürdige Biomassen (z. B. Rasenschnitte) aus außerlandwirtschaftlichen Bereichen erst in einen pumpfähigen Zustand gebracht und auch als Flüssigkeit auf den landwirtschftlichen Nutzflächen verteilt werden.
Zur Trockenen Vergärung sind mehrere Verfahrens-Varianten bekannt:To produce biogas, methanizable biomass (e.g. liquid manure or sewage sludge) is used microbiologically in fermenters either in liquid form (liquid fermentation) or in semi-moist form (dry fermentation). The liquid fermentation of liquid manure or sewage sludge, which is favored in the agricultural or municipal sector, is primarily geared towards internal use. Due to the low energy density of liquid manure, for example, transport is not worthwhile, which usually limits the profitability of these plants due to the size of their size. On the other hand, biomass worth exploiting (e.g. grass clippings) from non-agricultural areas must first be made pumpable and then distributed as a liquid on agricultural land.
There are several process variants known for dry fermentation:

- diskontinuierlilche Batch-Verfahren und- discontinuous batch processes and

- kontinuierliche bzw. semikontinierliche Verfahren- continuous or semi-continuous processes

Den kontinuierlichen bzw. semikontinuierlichen Verfahren ist gemeinsam, daß der Substrattransport im Fermenter entweder über Schwerkraft (fall down-Prinzip), mechanisch (Transportschnecke oder Zinkenförderer) oder in geschobenen Spezialbehältern und die Substrat-Homogenisierung mit Rührwerken oder durch Gaseinpressung erfolgen.
Bei der vorliegenden Erfindung handelt es sich um eine Vorrichtung zur wahlweisen Flüssigen oder Trockenen Vergärung in einem Gleitschicht-Fermenter, welcher im Längsprofil (Fig. 1) und Querschnitt (Fig. 2) vorgestellt wird. Dabei wird von einem stufenlos steuerbaren kontinuierlich arbeitenden Vergärungsverfahren ausgegangen, welches mit einem Minimum an technischen Vorrichtungen auskommt. Über einer Einschleusungsvorrichtung (vorzugsweise Syphon oder Mischerschnecke) wird z. B. stapelbare Biomasse/Substrat bevorratet, die/das kontinuierlich oder semikontinuierlich dem auf einer Schiefen Ebene angeordneten Gleitschicht-Fermenter zugeführt wird. Das Substrat gleitet dabei im Sinne des Hangabtriebs auf einer flüssigen Gleitschicht, wobei die "Fließgeschwindigkeit" vom Neigungswinkel des Fermenters, dem Substrat-Gewicht im Einschleusungsbereich, der Ausbildung und Qualität der Gleitflüssigkeit (Faulschlamm), der Reibung an den Fermenterwänden, vor allem aber der Einstellung einer mechanischen oder hydraulischen Bremsvorrichtung im Ausschleusungsbereich abhängt.What the continuous and semi-continuous processes have in common is that the substrate transport in the fermenter takes place either by gravity (fall down principle), mechanically (transport screw or tine conveyor) or in pushed special containers and the substrate homogenization with agitators or by gas injection.
The present invention is a device for optionally liquid or dry fermentation in a sliding layer fermenter, which is presented in longitudinal profile (Fig. 1) and cross section (Fig. 2). It is based on a continuously controllable, continuously operating fermentation process that requires a minimum of technical equipment. Stackable biomass/substrate, for example, is stored via an inlet device (preferably a siphon or mixer screw), which is fed continuously or semi-continuously to the sliding layer fermenter arranged on an inclined plane. The substrate slides on a liquid sliding layer in the sense of downhill drift, whereby the "flow speed" depends on the angle of inclination of the fermenter, the substrate weight in the inlet area, the formation and quality of the sliding liquid (digested sludge), the friction on the fermenter walls, but above all the setting of a mechanical or hydraulic braking device in the outlet area.

Somit hat die Vorrichtung einen 3-teiligen Aufbau: eine Einschleusungsvorrichtung, einen quaderförmigen oder röhrenförmigen modular erweiterbaren Fermenter-Teil und einen Ausschleusungsteil.The device therefore has a 3-part structure: an inlet device, a cuboid or tubular modular expandable fermenter part and an outlet part.

Die Einschleußung der Biomasse erfolgt vorzugsweise über eine syphonartige Ausbildung, so daß neben dem sicheren hydraulischen Gasverschluß eine Vortemperierung und Inoculation des Substrates gewährleistet ist. Der sich langsam voranschiebende Masse-Strom gelangt schließlichThe biomass is preferably introduced via a siphon-like structure, so that in addition to the secure hydraulic gas seal, pre-tempering and inoculation of the substrate is ensured. The slowly advancing mass flow finally reaches

in den Fermenterteil. In dessen vorderem Bereich befinden sich eine Vorrichtung (z. B. ein mit Preßluft beaufschlagbares Luftkissen) zur evtl. erforderlich werdenden Überwindung der anfänglichen Haftreibung sowie eine Vorrichtung (z. B. Rechen) zur Totalentleerung. Auf dem Fermenterboden bildet sich - vornehmlich durch die laufende Rezirkulation des entstehenden Perkolats - eine Gleitschicht, aufweicher das Substrat gleitend aufschwimmt. Der Fermenterteil schließt mit einer Staunase ab, die den Erhalt des Gleitfilms garantiert. Das Sammeln des Biogases im oberen Fermenterbereich erfolgt über längsverlaufende und überlappend angeordnete beheizbare Abdeckelemente, zwischen welchen Schlitze fur den Gasabzug sorgen. In diese Abdeckelemente sind auch die Verteilvorrichtungen (z. B. Überlaufgerinne) für das Perkolat integriert. Der Ausschleusungsteil besteht vorzugsweise aus einer luftdichten formlabilen Haube mit einer versteifbaren Rückwand, über welche über einstellbare Preßdrücke die Fließgeschwindigkeit des Substrat-Stroms reguliert werden kann. Dabei kann die Ausschleusung soweit gedrosselt werden, daß auch fließfähiges Substrat verarbeitet werden kann. Gleichzeitig befindet sich im Ausschleusungsteil eine Abtropfvorrichtung ( z. B. eine Rollenstrecke oder perforierter Boden) zum Sammeln des Perkolats, welches über einen Wärmetauscher temperiert in den Fermenter rezirkuliert wird. Für eine allenfalls notwendig werdende Mischung von Faulsubstrat mit Biomasse (Frischsubstrat) befindet sich entweder im Ein- oder Auschleusungsteil eine temperierbare Mischvorrichtung.into the fermenter section. In the front area there is a device (e.g. an air cushion that can be pressurized with compressed air) to overcome the initial friction that may be necessary, as well as a device (e.g. rake) for total emptying. A sliding layer forms on the fermenter floor - primarily through the ongoing recirculation of the resulting percolate - on which the substrate floats. The fermenter section ends with a retaining nose that guarantees the preservation of the sliding film. The biogas is collected in the upper fermenter section via longitudinal and overlapping heatable cover elements, between which slots ensure the gas extraction. The distribution devices (e.g. overflow channels) for the percolate are also integrated into these cover elements. The discharge section preferably consists of an airtight, form-stable hood with a stiffenable rear wall, via which the flow rate of the substrate stream can be regulated using adjustable pressures. The discharge can be throttled so that flowable substrate can also be processed. At the same time, the discharge section contains a dripping device (e.g. a roller section or perforated base) for collecting the percolate, which is recirculated into the fermenter at a temperature via a heat exchanger. If it becomes necessary to mix digested substrate with biomass (fresh substrate), there is a temperature-controlled mixing device either in the inlet or outlet section.
