METHOD AND APPARATUS FOR FERMENTOLYSIS Russian patent published in 1997 - IPC

FIELD: biogas production. SUBSTANCE: animal vital cycle products are concerned. Method consists in treating substrate by way of heating; dispersing substrate suspensions to particle sizes comparable with bacterium dimensions; growing bacterial biomass on produced substrate protecting it from external gas and temperature effects under stirring in chambers of acidic, regression acidic, and alkaline fermentation to form biogas and wort. Biogas and clarified wort are fed into methane fermentation chambers from which biogas is directed into tank located between coverings of acidic, regression acidic, and alkaline fermentation chambers and covering of casing. In the tank, water from biogas is condensed. Apparatus contains heating means and casing with process connecting pipes provided with non-rigid covering and with above- mentioned fermentation chambers also possessing non-rigid coverings facilitating formation of gas spaces under chamber coverings and between chamber coverings and that of casing. Non-rigid covering of casing can axially displace and is provided with hydraulic gate in the form of two concentrically disposed tubes, the outer one being mounted on the bridge between the chambers, whereas inner one is fastened on covering of casing free to displace relative to outer tube and is connected to biogas consummation source. Coverings of chambers have hydraulic valves to discharge condensate into chambers. Means for dispersing suspensions of substrate being processed, stirring means, and biogas consummation source are also available. EFFECT: enhanced efficiency of process. 2 cl, 5 dwg
