Description
Technical Field
The utility model relates to the technical field of extraction and multistage fractionation, in particular to a subcritical extraction and multistage fractionation integrated device.
Background
Subcritical water, also known as super heated water, high pressure hot water or hot liquid water, means that under a certain pressure, water is heated to a high temperature above 100 ℃ and below 374 ℃ of critical temperature, and the water body is still kept in a liquid state. The hydrogen bond, ion hydration, ion association, cluster structure and the like of the fluid microstructure are changed in the subcritical state, so that the physical and chemical properties of subcritical water are greatly different from those of water at normal temperature and normal pressure. The polarity of water at normal temperature and normal pressure is strong, and in a subcritical state, as the temperature rises, hydrogen bonds of subcritical water are opened or weakened, so that water is extracted from high to low. Therefore, the polarity of the water can be changed in a larger range by controlling the temperature and the pressure of subcritical water, so that the continuous extraction of the effective components in the natural product from the water-soluble components to the fat-soluble components can be realized, and the selective extraction can be realized. In addition, since subcritical water extraction uses inexpensive and pollution-free water as an extractant, subcritical water extraction technology is regarded as a green and environment-friendly and promising innovation technology.
The subcritical water extraction equipment has high temperature and high pressure (150-374 ℃ and 0.4-22.1 MPa), and after extraction and separation are carried out in the extraction tank, the residual liquid in the extraction tank still has high temperature and high energy; if not used, waste is caused; secondly, the extraction tank is used for extracting the effective components in the shells, the shells are crushed and then poured into the extraction tank for subcritical extraction, however, a large amount of shell crushed aggregates are contained in the high-temperature liquid, and the high-temperature liquid is not beneficial to secondary utilization.
