Abstract

The invention discloses a biomass extraction system. The system includes a mother liquor, the mother liquor is subjected to extraction, back extraction, hydrolytic precipitation, filtration and dryingto obtain biomass, the mother liquor enters a first extraction tower, an extraction agent is added for first extraction, the obtained first extraction product enters a second extraction tower, the extraction agent is added for second extraction, the obtained second extraction product enters a third extraction tower, the extraction agent is added for third extraction, the obtained third extractionproduct enters a fourth extraction tower, the extraction agent is added for fourth extraction, the extracted mother liquor enters a first back extraction tower, and a back extraction agent is added for first back extraction. The invention relates to the technical field of biomass extraction. The biomass extraction system achieves the purposes of good separation effect, large production capacity,high biomass recovery rate, high product purity, continuous operation, easy automation, improvement of the biomass extraction efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of biomass extraction, in particular to a biomass extraction system. Background technique [0002] Biomass refers to various organisms formed through photosynthesis, including all animals, plants and microorganisms. Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It has always been one of the important energy sources for human survival, and it is the fourth largest energy source after coal, oil, and natural gas. plays an important role in the system. Among them, the extraction method is more widely used. Commonly used extractants are CCl 4 , TBP, 8-hydroxyquinoline, long-chain amine, etc. Biomass extraction is to use Kelexl00 to extract biomass in kerosene system. Extraction of biomass by Kelexl00 is carried out in an acidic medium, which requires a high concentration of extractant and high acidity, otherwise it will be difficult to extract and affect ...
