ANAEROBIC REACTOR Russian patent published in 2008 - IPC C02F3/28 

FIELD: engines and pumps, chemistry.

SUBSTANCE: invention can be used for production of biogas. The anaerobic reactor incorporates liquid and solid substance preliminary acidation section 2, reactor with basic load section 3a and low load section 3b wherein acidated substances are subjected to fermentation and final settling section 4. Partition 17 is arranged between preliminary acidation section 2 and basic load section 3a. Double partition 18 is arranged is arranged behind the basic load section 3a and low load section 3b, while partition 19 is arranged between the low load section 3b and final settling section. Preliminary acidation section 2 accommodates mixers 6, 7, driven by the control device 14 via signaling or feeding wires 15. Control device 14 is connected, via signaling or feeding wire 16, with pump 5c forcing the substances through pipes 5a and 5b from section 2 into the basic load section. Transport facilities 5a, 5b, 5c designed for transfer of the liquid and solid substances from preliminary acidation section 2 into reactor 3a, 3b comprise the means to keep weakly dissolved solid substances till sufficient acidation and to force sufficiently acidated substances further on.

EFFECT: simple and efficient production of biogas from liquid and solid substances.
