FERMENTER Russian patent published in 1997 - IPC

FIELD: waste disposal. SUBSTANCE: invention consists in that fermentation in chambers of sections of anaerobes hydrolytics, acidogens, acetogens, and acetohydrogens is accompanied with crushing organics by grainy abrasive filling under vibrations transmitted from vibrator, suspended materials passing successively from connecting pipe over chambers and compensation members and gates retaining grainy filling and coarse suspended inclusions. Gaseous break-down products enter collectors and therefrom methanogens' section collector. In chambers of this section, methanogens convert carbon dioxide into methane. Grainy abrasive filling initiates partially destroying methanogen cell shells in chambers releasing enzymes which provides methanogen enzimolysis, that is decomposition of water into oxygen and hydrogen. As a result, mass of biogas exceeds that of destroyed organics. Carrying out fermentation in separate sections minimizes suppression of vital activity of one type of bacteria by metabolites of other-type bacteria and successive passage from acidic medium to low-alkaline one in section. Simultaneously, biogas in methanogens is set free of noxious components, e.g. hydrogen sulfide, which makes possible using this gas as combustible in internal combustion engines. EFFECT: enhanced efficiency of process and enlarged fuel resource. 4 dwg
