High-efficiency bioreactor capable of realizing gas-liquid atomization

Abstract

The invention discloses a high-efficiency bioreactor capable of realizing gas-liquid atomization. The high-efficiency bioreactor comprises a main bioreactor body (1), gas deflectors (2), a three-phaseseparator (3), a discharge outlet (4), a gas outlet (5), a filtration system (6), a gas inlet (7), a liquid inlet (8), a gas-liquid mixer (9), an atomization system (10), a feed inlet (11), a liquiddistributor (12), a gas cabinet (13) and an external circulation system (14). The high-efficiency bioreactor capable of realizing gas-liquid atomization mainly adopts the principles of gas-liquid mixing and atomization to realize mixing and atomization of liquid and gas; after mixing and atomization, the gas and the liquid are jetted into the bioreactor, so the liquid and the gas can more fully contact with microorganisms in the bioreactor; and thus, mass transfer effect is enhanced, and the efficiency of the bioreactor is improved. The high-efficiency bioreactor is applicable as an aerobic aeration device, a device for reducing carbon dioxide with hydrogen, an airlift bioreactor, an expanded granular sludge bed reactor, an internal circulation reactor, a gas-stirring fully-mixing reactor,and the like.

Description

technical field [0001] The invention relates to a gas-liquid atomization high-efficiency bioreactor, belonging to the field of bioreactors. Background technique [0002] A bioreactor is a device system that uses the biological functions of enzymes or organisms (such as microorganisms) to perform biochemical reactions in vitro. It is a biological function simulator, such as a fermenter, immobilized enzymes or immobilized cell reactors Wait. It has important applications in wine, pharmaceutical production, concentrated jam, fruit juice fermentation, and degradation of organic pollutants. [0003] In terms of aerobic bioreactors, especially in terms of aeration, the smaller the gas particles, the better, and the fuller the contact between the gas and the raw materials, the better; in terms of anaerobic bioreactors, external hydrogen is used to reduce the carbon dioxide in the reactor , so as to increase the methane content in the biogas, but it cannot ensure that the hydrogen...

[0003] In terms of aerobic bioreactors, especially in terms of aeration, the smaller the gas particles, the better, and the fuller the contact between the gas and the raw materials, the better; in terms of anaerobic bioreactors, external hydrogen is used to reduce the carbon dioxide in the reactor , so as to increase the methane content in the biogas, but it cannot ensure that the hydrogen gas introduced can be evenly distributed and fully contacted with the microorganisms in the reactor. Using biogas to expand the sludge in the high-efficiency reactor, because the gas cannot be made smaller, it is easy channeling in the reactor
