BIOGAS PLANT FERMENTER TANK, SERVICE DEVICE FOR MOUNTING ON A BIOGAS PLANT FERMENTER TANK AND METHOD FOR OPERATING A BIOGAS PLANT FERMENTER TANK

摘要

The invention relates to a biogas plant fermenter tank (1) comprising an essentially liquid substrate (6) accommodated in the container inner chamber (5) and at least one stirring device (8) arranged in the container inner chamber (5). According to the invention, an injection device (9) having at least one delivery pump (10) which extracts the injection fluid (12), and at least one injection nozzle element (11) which is fluidcally connected to the at least one delivery pump (10), is provided. The injection liquid (12) can be injected into the fermenter container (1) by means of said injection device in such a way that the injection liquid is injected as a liquid jet (13) from above onto the surface of a floating layer (7) of the substrate (6) and wets the latter.
