Problems solved by technology
In the process of industrial waste gas fermentation to produce ethanol, CO gas is used as the carbon source of the fermentation liquid. The gas-liquid two-phase section after the two contact not only reduces the efficiency of the pump, but also causes the membrane group to vibrate due to the existence of two-phase slug flow. Reduce the operating life of the membrane tube and affect the mechanical stability of the membrane group

A gas-liquid two-phase material system for preparing ethanol by industrial waste gas fermentation method comprises a fermentation tank, a fermentation tank circulating pump, a ceramic membrane circulating pump, a ceramic membrane group, a concentrated liquid storage tank and a clear liquid storage tank, the mash output end of the fermentation tank is communicated with a first transverse pipe, oneend of the first transverse pipe is communicated with the fermentation tank circulating pump, the outlet end of the fermentation tank circulating pump is communicated with a second transverse pipe; and the second transverse pipe is communicated with the top of the fermentation tank through the second vertical pipe. CO gas in industrial tail gas is used as a carbon source required by a fermentationstrain for biological fermentation, and the feeding position of a ceramic membrane group in a gas-liquid coexisting material is at the lower part of a circulating pipeline of a fermentation tank andused as a feeding point, so that large bubbles accumulated in a horizontal pipeline in a gas-liquid slug flow are realized, mechanical vibration is reduced. The goal of improving the membrane group operation efficiency and the mechanical stability is achieved.
Description
technical field [0001] The invention belongs to the field of ethanol produced by industrial waste gas fermentation, and in particular relates to a gas-liquid two-phase material system in ethanol produced by industrial waste gas fermentation. Background technique [0002] Industrial waste gas contains a large amount of C0 poisonous gas. Traditionally, the C0 in metallurgy-related industrial tail gas will be burned as fuel gas to produce heat and sent to thermal power plants for heat recovery and utilization. However, the C02 produced after combustion will be discharged into the atmosphere, which will still cause Air pollution aggravates the greenhouse effect. Ethanol produced by industrial waste gas fermentation is an energy-saving and environmentally friendly new energy technology method. It uses the characteristics of Clostridium ethanolum to consume C0, converts inorganic carbon into organic carbon, and reduces carbon elements from entering the atmosphere in the form of gr...
