METHANE TANK Russian patent published in 2012 - IPC C02F11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to environmental protection and serves to process organic substrates with relative moisture content of 90-98%, i.e. unpadded manure, excrements of agricultural animals, sediments and silt, and industrial and household effluents. Methane tank for anaerobic treatment of organic substrates consists of tight case with initial substrate feed branch pipes and treated substrate discharge branch pipes, biogas discharge branch pipe, and central tube. Tube top and bottom are exposed with respect to methane tank inside. Biogas feed branch pipe is arranged coaxially inside central tube bottom and communicated compressor with biogas discharge branch pipe. Methane tank incorporates vertical immobilisers of anaerobic micro flora arranged between central tube and methane tank case and made up of set of vertical rods with porous structure and combined by stiff frame-type suspension coupled via shaft with the drive.

EFFECT: optimised homogenisation and heating, developed interphase mass exchange.
