Abstract

A small-scale reactor continually generates methane from the fermentation of household organic refuse. The reactor is a gas-tight assembly into which refuse is introduced especially by a gas-tight tube with a helical feed core.

Description

Vorbekannt ist ein Kleinfermenter zur Methanisierung von Biomüll (AZ 100 16 152.9), welcher im absätzigen Verfahren (batch-Verfahren) arbeitet. Die vorliegende Erfindung erweitert diese Schutzrechtsanmeldung durch eine technische Erweiterung, die auch einen kontinuierlichen Betrieb erlaubt. Dies wird durch die Beschickung und Entleerung mittels einer Förderspirale etc. und die besondere Ausbildung des Fermenterbodens erreicht. A small fermenter for the methanization of organic waste (AZ 100 16 152.9) is known works in a batch process. The present invention extends this Industrial property registration through a technical extension, which is also a continuous Operation allowed. This is done by loading and emptying using a conveyor spiral etc. and achieved the special training of the fermenter bottom.

Für die Eintragung ist ein Einfülltrichter (1) vorgesehen, der einen Schieber oder eine Rückstromklappe (2) etc. zum luft- und geruchsdichten Verschluß der Einfüllleitung besitzt. Über eine motorisch angetriebene Fördervorrichtung z. B. einen Spiralförderer wird das Substrat dem Fermenter zugeführt. Dabei kann eine integrierte Heizungs- und Isolationsummantelung angebracht sein, damit das in der Leitung stehende Substrat bereits vorgewärmt in den Fermenter gelangt. Der in der Leitung stehende Substratpfropf schließt dabei die Fermenteranlage zusätzlich noch luftdicht ab. A filling funnel ( 1 ) is provided for the entry, which has a slide or a backflow flap ( 2 ) etc. for the air and odor-tight closure of the filling line. About a motorized conveyor z. B. a spiral conveyor, the substrate is fed to the fermenter. An integrated heating and insulation jacket can be attached so that the substrate in the pipe is already preheated and reaches the fermenter. The substrate plug in the line also closes the fermenter system in an airtight manner.

Der perforierte Behälterboden (3), der die Phasentrennung für das Perkolat und den Feststoffanteil bewerkstelligt, besitzt eine produktspezifische einseitige oder beidseitige Schräge mit entsprechender Ablaufrinne, in welcher sich die ebenfalls luftdicht abschließende Austragsvorrichtung - beispielsweise wieder ein Spiralförderer (4) - befindet. Statt der Phasentrennung im Fermenter, kann diese auch über eine doppelwandige Ausgestaltung mit Perforierung der Innenwand des Förderorgans geschehen bzw. der ganze Austragungsvorgang kann auch ohne Phasentrennung realisiert werden. Die Luftdichtigkeit wird durch Schräglage des stets gefüllten Förderkanals erreicht. The perforated container base ( 3 ), which manages the phase separation for the percolate and the solid content, has a product-specific one-sided or double-sided bevel with a corresponding drainage channel in which the discharge device, which is also airtight, is located - for example, a spiral conveyor ( 4 ). Instead of the phase separation in the fermenter, this can also take place via a double-walled configuration with perforation of the inner wall of the conveying member or the entire discharge process can also be carried out without phase separation. The airtightness is achieved by the inclined position of the always filled feed channel.
