BIOENERGETIC STATION Russian patent published in 1996 - IPC

FIELD: biological processing of liquids, animal husbandry rejects, and waste water to produce biogas, fertilizers, and electric power. SUBSTANCE: bioenergetic station has collector of damp sludge 1 connected by pipeline through pump 2 and trap 3 with heater of damp sludge 4 having device 5 for stirring sludge. Methane tank 8 is provided with drive stirrer 9 for stir sludge under fermentation and its top section is connected with gas holder 10. Collector-neutralizer 11 is successively lied with centrifuge 12 and collector-aerator 13. Pipeline with controlled valve 56 links bottom section of methane tank 8 with damp sludge collector 1. Station also has heating devices placed in heater 4 and methane tank 8 and station-controlling unit 14. Stirring device 5 in the damp sludge heater is made as a perforated conducting tube 22 coupled with pipeline for damp sludge 17. Electrode 26 is installed along tube axis and is made as a helical blade 28 with source of controlled pulls power supply. Drive stirrer 8 has the form of a worm with blade 48 whose upper and lower surfaces are provided with substrate 47 for immobilizing microorganisms. Hollow worm shaft is connected with methane tank room. EFFECT: increased performance and sanitary hygienic safety, reduced power expenses. 3 cl, 3 dwg
