ANAEROBIC PROCESSING PLANT Russian patent published in 1997 - IPC

FIELD: fermentation processes. SUBSTANCE: plant contains first and second-phase acid and methane fermentation chambers with process connecting pipes. Chambers have false bottoms under which brew collectors with pulsators are thus formed. First-phase chambers are provided with (i) gas-impermeable barriers in their upper parts to form gas spaces and (ii) grainy charge. Chambers are interconnected through connecting pipes. Brew collectors of first-phase chambers communicate with second-phase chambers made in the form of towers with continuous partitions forming sections provided with beam bubblers and interconnected through pipes. Lower sections of second-phase chambers contain grainy charge placed on false bottoms. Brew collectors of second-phase chambers communicate with biocultivator made in the form of well with continuous partitions forming sections with beam bubblers and immobilization charge in the form of fiber bundles. EFFECT: enhanced efficiency of process. 1 dwg
