Embodiment Construction

[0024] The exemplary biogas plant proposed by the present invention has three fermenters 1 that can be operated independently of each other, and these fermenters can all use their gas outlet 7 to selectively communicate with the first biogas conduit 4, the second biogas conduit 6 or an exhaust gas A conduit 10 is connected, which leads to an exhaust gas treatment point 11 . The biogas flows introduced into the biogas lines 4 and 6 can be mixed with one another or fed separately to a biogas utilization device 2 . The exemplary biogas plant proposed by the invention is equipped for this purpose with a control device 8 for mixing the two biogas streams. Furthermore, a measuring device 13 is provided, which measures the methane content of the biogas fed to the biogas utilization device 2 . The biogas line 4 is connected to the biogas storage 3 designed as a weak biogas storage. In this case, the biogas can be conveyed to or removed from the first biogas store 3 in a targeted man...

Abstract

A biogas plant has at least one fermenter (1), preferably a dry fermenter for generating biogas, in addition a biogas utilization appliance (2) and a first gas store (3) for storing biogas. The gas store (3) is connectable to a first biogas conduit (4) that is connectable to a gas outlet (7) of the at least one fermenter (1). The biogas plant has a second gas store (5) for storing biogas. The second gas store (5) is connectable to a second biogas conduit (6) that is connectable to a gas outlet (7) of the at least one fermenter (1). The biogas utilization appliance (2) is connectable to the first biogas store (3) and / or to the first biogas conduit (4) and to the second biogas store (5) and / or to the second biogas conduit (6). The biogas plant has a control appliance (8) for controlling the quantitative ratios of the biogas streams conducted from the biogas conduits (4, 6) and / or the biogas stores (3, 5) to the biogas utilization appliance.

Description

technical field [0001] The invention relates to a biogas plant with at least one fermenter for producing biogas and to a method for operating a biogas plant. Background technique [0002] Such biogas plants are used to produce methane-containing biogas, which is used, for example, in a blockheizkraftwerk to generate energy. Here, the fermenters are operated in stream mode, i.e. no steady-state operation of the fermenter takes place between filling the fermenter with biomass to be fermented or emptying it with already fermented biomass . More precisely, at the beginning and end of biomass fermentation there are start-up and stop phases in which gases or gas-air mixtures are produced which are especially due to too low a methane content There is no use value. These gas mixtures are now either removed or sent to another exhaust gas treatment. The efficiency of the biogas plant is reduced due to the loss of possibly valuable methane in this case. Other losses on conventiona...
