BIOGAS GENERATION UNIT Russian patent published in 1996 - IPC

FIELD: unit for generating biogas from animal and bird activity products. SUBSTANCE: unit has methane-tank casing buried into ground and provided with roof and acid, acid regression and alkaline fermentation chambers with roof. Biogas chambers and biogas container casings are defined below roofs. Acid regression and alkaline fermentation chambers are provided with silt-laden water accumulators. Biogas container positioned below acid fermentation chamber and acid regression fermentation chamber has gas gate for separating container from alkaline fermentation chamber. Biogas generating unit has sectioned methane fermentation precombustion chamber communicated with silt-laden water accumulator of acid regression fermentation chamber. Sections of precombustion chamber are communicated with biogas container below roofs of acid fermentation chamber and acid regression fermentation chamber. Methane fermentation chamber is made sectioned and is communicated with silt-laden water accumulator of alkaline fermentation chamber. Sections of methane fermentation chamber are communicated with biogas container below alkaline fermentation chamber. EFFECT: increased efficiency and enhanced reliability in operation. 5 dwg
