BIOREACTOR WITH MEMBRANE DEVICE FOR GAS SUPPLY OF MICROORGANISMS Russian patent published in 2016 - IPC C12M1/04 C12M1/34 C12M1/36 

FIELD: biochemistry.

SUBSTANCE: invention relates to biochemistry. Proposed is a bioreactor with a membrane device for gas supply of microorganisms. Bioreactor comprises a cylindrical housing, a cover, a bottom, a heat exchanger, a gas distributor, an aerator, a methane collector, tubular gas-permeable polymer membranes, branch pipes for the working liquid and gas flowing, an analyzer of exhaust gases CH₄, O₂, CO₂, sensors of pH and T°C, electronic air flow and carbon dioxide meters, methane pressure regulator and enzymatic process controller. Gas distributor is equipped with guide plates and an aerating air diffuser, herewith it is made as a multichannel gas-lift pump. Methane collector is equipped with perforated holes for passage of liquid-gas mixture through the gas distributor. Separator of exhaust gases from liquid products of fermentation is equipped with working fluid level sensor and a pipeline connecting the lower part of the separator with the bottom part of the bioreactor.

EFFECT: higher efficiency and explosion safety of bioreactor are provided.
