An embodiment of the present invention provides an industrial gas biological fermentation device, comprising: a fermenter, the fermenter includes: a downcomer; a spray device, arranged on the top of the fermenter; a first pipeline, the first pipeline One end communicates with the downcomer; the first gas-liquid separation device includes: a first inlet, the first inlet communicates with the other end of the first pipeline; a first outlet; a second outlet, the second outlet It communicates with the top of the fermentation tank; a spray pump, the inlet of the spray pump communicates with the first outlet, and the outlet of the spray pump communicates with the spray device. It solves the technical problems in the prior art that during the operation of the fermentation system, the fermentation liquid contains gas, which causes the vibration of the pump and the pipeline to exceed the standard, and the failure rate of the machine seal and the welding joint of the pipeline increases, and achieves the improvement of the fermentation liquid flowing through the pump. Gas-liquid separation, reducing the vibration of pumps and pipelines, and reducing the failure rate of mechanical seals and pipeline welding joints.
Description
technical field [0001] The invention relates to the technical field of biological fermentation, in particular to an industrial gas biological fermentation device. Background technique [0002] The production of fuel ethanol by industrial gas biological fermentation is an emerging high-tech production process. This process uses industrial gas as raw material, adopts biological fermentation, and undergoes pretreatment, fermentation, distillation, dehydration and other processes to produce fuel ethanol. Fermentation The liquid contains 13-19% of entrained gas, and the gas has reached a saturated dissolved state under operating conditions. [0003] However, the inventors of the present application have found that the above-mentioned prior art has at least the following technical problems: [0004] At present, there is no better gas-liquid separation system device containing saturated gas in the fermented liquid. The gas in the fermented liquid is composed of (volume fraction) 5...
