Abstract

The invention relates to a myrialiter-grade supercritical carbon dioxide fluid extraction system. The myrialiter-grade supercritical carbon dioxide fluid extraction system comprises a condensing system, an extraction system, a separation system and a recovery system which are arranged in a sequentially connected mode. By arranging the condensing system adopting two stages of condensers, the extraction system comprises five-stage series-connection extraction kettles with the height-diameter ratio being (8 to 20):1, the separation system adopts a separation kettle and cyclone hydraulic separatorcombined mode, the arranged recovery system comprises a recovery condenser, an exhaust gas tank and a diaphragm compressor, thus the total extraction volume of the supercritical carbon dioxide fluidextraction system reaches the myrialiter grade, energy consumption can be greatly saved, the utilization rate of carbon dioxide is increased, and zero emission of carbon dioxide is achieved. Through data, it is shown that the energy consumption cost of the supercritical carbon dioxide fluid extraction system is reduced from about 5,000 yuan to 1,000 yuan for treating of a single ton of materials,and a solid step is advanced more for replacing a traditional solvent leaching process.

Description

technical field [0001] The invention belongs to the technical field of extraction technology, and in particular relates to a 10,000-level supercritical carbon dioxide fluid extraction system. Background technique [0002] Supercritical carbon dioxide fluid extraction technology is the most environmentally friendly and safe natural product extraction technology recognized internationally so far. It can carry out directional extraction of specific components beneficial to the human body in different animals and plants. The whole process of extraction is low temperature, and the biological activity of the components is completely preserved. Compared with the existing extraction processes, namely steam distillation and organic solvent extraction, It solves the shortcomings of large damage to the biological activity of active ingredients, large solvent residues in the product, large environmental pollution, and great energy consumption. [0003] In the supercritical carbon dioxi...
