BIOREACTOR Russian patent published in 2003 - IPC

FIELD: biotechnology. SUBSTANCE: bioreactor has casing with branch pipes for supplying biomass to be reprocessed, for discharging ready fertilizer, for discharging biogas, bubbler, and biomass heating device. Bubbler has vertical gas duct continued with horizontal outlets equipped with nozzles, and vertical pipes arranged inside biomass for cooperating with nozzles. Biomass supplying branch pipe and ready fertilizer discharge branch pipe are positioned on single casing end wall. Biomass heating device is made in the form of narrow rectangular tank filled with heated water to the height exceeding the level of biomass in casing. Narrow rectangular tank is positioned lengthwise of casing and adjoins with its end wall to casing end wall at charging and discharge side in equally spaced relation with respect to casing side wall, said space being equal to distance between second end walls of rectangular tank and casing. Bubbler horizontal outlets are located in lower part of rectangular tank along its side walls. Nozzles are disposed in equally spaced relation lengthwise of horizontal outlets. Rectangular tank divides casing bottom into two portions inclined to opposite sides at angle of discharge of biomass. Bioreactor may be used for fermentative reprocessing of organic plant and animal wastes, domestic wastes, forestry and wood-working industry wastes etc for producing ecologically clean fertilizer and biogas. EFFECT: increased intensity, stable operation and completeness of biochemical processes in bioreactor and simplified maintenance and operation. 2 dwg
