Supercritical extraction technology imitating ultrasonic high-speed separation

Abstract

The invention discloses a supercritical extraction technology imitating ultrasonic high-speed separation, and belongs to the field of supercritical extraction. According to the supercritical extraction technology imitating ultrasonic high-speed separation, through a micro ultrasonic bag arranged on the lower portion of a binary separation tank, an ultrasonic cavity is formed, through a gas opening, the ultrasonic cavity can be filled with gas continuously, the gas can be pumped out of the ultrasonic cavity continuously, thus continuous switch of expanding and shrinkage of transformation bulgeparts can be effectively controlled, then a micro-elastic baseboard is driven to shake continuously, thus a binary intermediate shakes, due to temperature rise and decompression, carbon dioxide in thebinary intermediate returns to a gas state, and through shaking, the movement speed of gaseous carbon dioxide molecules can be effectively improved, so that release of gaseous carbon dioxide is effectively accelerated, then the efficiency of medicine extraction is significantly improved, meanwhile, by arranging an inner expansion stabilizing pipe with variable volume, the flow speed of the gaseous carbon dioxide can be improved, the possibility that the binary separation tank internally explodes due to the fact that gas is not discharged in time is effectively avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the field of supercritical extraction, in particular to a supercritical extraction process imitating ultrasonic high-speed separation. Background technique [0002] The state in which the pressure and temperature of a substance exceed its critical pressure (Pc) and critical temperature (Tc) at the same time, or the state in which the relative pressure (P / Pc) and relative temperature (T / Tc) of a substance are greater than 1 at the same time is called The supercritical state of the substance. There are three phases of any kind of matter—gas, liquid, and solid. The point at which the liquid and gas phases are in equilibrium is called the critical point. The temperature and pressure at the critical point are called the critical temperature and critical pressure (the critical temperature and critical pressure of water are 374°C and 21.7MPa, respectively). Different substances require different pressures and temperatures for their...

AI Technical Summary

Problems solved by technology

[0005] Supercritical carbon dioxide extraction is to change carbon dioxide into supercritical fluid, use carbon dioxide supercritical fluid as a solvent, dissolve the substance to be extracted, and then change the carbon dioxide in the supercritical fluid into gaseous carbon dioxide by increasing the temperature and reducing the pressure, so that the obtained The extract is more pure, so many medicines are extracted in this way, so that the obtained extract does not contain other impurities. In the process, although the temperature rise will accelerate the release of carbon dioxide, the release of carbon dioxide is an autonomous release, resulting in a faster release rate. It will still be affected to a certain extent, resulting in a longer process of drug extraction, which reduces the efficiency of drug extraction
