APPARATUS FOR PRODUCING BIOGAS Russian patent published in 2025 - IPC C12M1/00 C12M1/107 C12M1/113 

FIELD: treating manure; production of biogas.

SUBSTANCE: device for producing biogas relates to agriculture and is meant for separating biogas from liquid slurry manure with subsequent purification, compression and storage thereof. Device consists of fermenter-gas holder, on which heat insulation material is located on the outside, which is protected from above with metal profile sheet. Air-tight cover is mounted on top of the fermenter-gas holder. Space inside under the cover is separated from the space of the fermenter-gas holder with a gas-tight membrane. Pipe connected with blower and silencer is arranged between cover and gastight membrane. Mixers are fixed on shaft inside fermenter-gasholder. On one side shaft is installed in bearing, which is installed in fermenter-gas holder, and on other side shaft is installed in bearing, which is mounted on stand. In the lower part of the fermenter-gas holder there is a pipe for removing liquid slurry manure without litter. Above the mixer there is a pipe for supply of liquid slurry manure inside the fermenter-gasholder. In the middle of the gas holder fermenter, below the gas-impermeable membrane, there is a disc to prevent liquid slurry manure drops from falling into the pipe, which is installed in the middle of the disc with the hole upwards and is intended to allow the biogas to move along it to a fan located on the pipe and intended to increase the biogas pressure for the possibility of supplying the biogas through the filter. Filter is connected by means of pipe to compressor plant, which is connected to biogas storage tanks.

EFFECT: device provides reduced heat losses inside fermenter-gas holder and increases volume of biogas production.
