BIOGAS APPARATUS FOR ANAEROBIC FERMENTATION OF ORGANIC WASTES Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, utilization of biomass in processing of animal wastes.

SUBSTANCE: biogas apparatus has multiple-section reactor comprising bottom inclined from charging unit to discharge unit. Charging and discharge units are made in the form of containers with drive. Apparatus is further provided with mixers having blades whose length exceeds biomass level, and gas holder. Mixers are arranged in each section of reactor and kinematically connected with charging unit drive. Apparatus has mass pump and water heating boiler equipped with gas burners communicated with gas holder. Charging and discharge units are made in the form of screw conveyors comprising housing and shaft provided with spiral. Charging unit conveyor shaft is made hollow and perforated. Discharge unit conveyor housing has hermetically sealed cylindrical vessel mounted above biomass level to define in conjunction therewith annular cavity communicated with charging unit conveyor shaft cavity through water heating boiler and mass pump. Housing part adjoining vessel is made perforated.

EFFECT: increased intensity of biomethonogenesis process owing to increased concentration of anaerobic mass and homogeneity of substrate delivered into reactor.
