Abstract

The invention relates to a biogas plant having a reactor 1 which has a central tube 17 to which is fed the biomass 18. Around the central tube 17 is built up support material 4 for microorganisms and, on the inner walls of the reactor 1, in addition, there is further applied support material 3 for microorganisms. The central tube 17 is formed by support material 4 which has channels 13 which, in the case of the central tube 17 pass through the support material, but in the case of the support material 3 on the inner wall of the reactor 1 are only open towards the interior. <IMAGE>

 ist,In der Ausführungsform gemäss Fig. 1 befindet sich in dem Raum, der von dem   Trägermatenal   4 des Zentralrohres 17 umschlossen ist, eine Rühreinrichtung 9. 



  Diese Rühreinrichtung 9 ist dabei mittig im Zentralrohr 17 angeordnet. 



  In der Ausführungsform gemäss Fig. 2 mündet in den von dem Zentralrohr 17 umschlossenen Innenraum das Rohr 11 einer Mammutpumpe ein. 



  Sowohl die Mammutpumpe als auch die Rühreinrichtung 9 sorgen für eine Bewegung der organischen Substanzen im Reaktor 1. Im Falle der Verwendung einer Rühreinrichtung 9 kann die Strömung, je nach Drehrichtung der Rühreinrichtung 9, bzw. der Drehrichtung des Schneidwerkes 24 der   Rühreinrichtung.   eine Strömung in Richtung des Doppelpfeiles 14 erfolgen. Bei Verwendung einer Mammutpumpe, wie des Fig. 2 zeigt, ist eine Strömung nur in Richtung der Pfeile 21 möglich. In beiden   Fällen wird Jedoch   die organische Substanz durch die   Hohlräume   13 des Trägermaterials 4 bewegt. Gleichzeitig wird durch die im Bodenbereich angeordneten Öffnungen 8 und durch die Öffnung des Zentralrohres 17 an seinem oberen Ende. die organische Substanz gepumpt. 



   Um nun bel Verwendung der Rühreinrichtung 9 einen besseren Gaseintrag in die Biomasse zu erreichen, ist ein Rohr 5 vorgesehen (Fig.   1),   durch welches mit Hilfe des durch das Schneidwerk 24 der Rühreinrichtung erzeugten Unterdruckes, Biogas aus dem Gasraum 23 der Biogasaniage angesaugt und in die organische Substanz Im Innenraum des Zentrairohres 17 gebracht werden kann.

 In the embodiment according to FIG. 1 there is a stirring device 9 in the space which is enclosed by the carrier material 4 of the central tube 17.



  This stirring device 9 is arranged centrally in the central tube 17.



  In the embodiment according to FIG. 2, the tube 11 of a mammoth pump opens into the interior enclosed by the central tube 17.



  Both the mammoth pump and the stirring device 9 ensure a movement of the organic substances in the reactor 1. If a stirring device 9 is used, the flow can, depending on the direction of rotation of the stirring device 9, or the direction of rotation of the cutting unit 24 of the stirring device. a flow in the direction of the double arrow 14. When using a mammoth pump, as shown in FIG. 2, a flow is only possible in the direction of the arrows 21. In both cases, however, the organic substance is moved through the cavities 13 of the carrier material 4. At the same time, through the openings 8 arranged in the bottom area and through the opening of the central tube 17 at its upper end. pumped the organic matter.



   In order to achieve better gas introduction into the biomass bel using the stirring device 9, a tube 5 is provided (FIG. 1) through which, with the help of the vacuum generated by the cutting device 24 of the stirring device, biogas is sucked out of the gas space 23 of the biogas plant and can be brought into the organic substance in the interior of the central tube 17.
