Device to produce biogas

摘要

A device to produce biogas that includes at least one fermenter (1) to receive a substrate (2) to be percolated, and a percolate container (3). The fermenter (1) and the percolate container (3) are connected with each other such that the percolate within the fermenter (1) seeping through the substrate (2) makes its way into the percolate container (3) which serves as a thermal reservoir, from which it may be directed back to the fermenter (1) as necessary. The percolate container (3) serving as a thermal reservoir and/or the sand trap which serves as a percolate collector (5) are located at least partially below the floor surface (1a) of the fermenter (1).

主权项

1. A device for fermenting a substrate and for obtaining biogas from said fermented substrate, said device having at least one fermenter (1) for receiving a substrate (2) which is to be percolated during fermentation, as well as a percolate container (3) for recovering percolate, wherein the fermenter (1) and percolate container (3) are fluidly connected to one another so that the percolate seeping through the substrate (2) disposed on one side of a generally non-porous base surface (1a) in the fermenter (1) passes into the percolate container (3) and can be returned from there when necessary back again into the fermenter (1), wherein at least in part on a second side of the generally non-porous base surface (1a) of the fermenter (1) there is a heat reservoir in the form of the percolate container (3) and a percolate collecting device (5), characterised in that the percolate collecting device (5) is fluidly connected between the fermenter (1) and the percolate container (3) and is arranged underneath the generally non-porous base surface (1a) of the fermenter (1) and laterally adjacent said percolate container (3) and configured for cleaning percolate flowing from the fermenter (1), such that percolate flowing from the fermenter (1) first flows into the percolate collecting device (5) to be cleaned prior to said cleaned percolate flowing into the percolate container (3), and wherein said generally non-porous base surface (1a) forms a common heat exchange surface between at least the percolate container (3) and the fermenter (1).
