The invention discloses a supercritical water extraction system, which relates to the supercritical field, and is characterized in that the supercritical water extraction system comprises an extraction purification system and a control system acting on the extraction purification system, and the control system enables water in the extraction purification system to be in a supercritical state; the extraction and purification system comprises an extraction device, a primary purification device communicated with the extraction device and a secondary purification device communicated with the primary purification device; the extraction device comprises an extraction reaction cavity and a catalyst adding assembly arranged on the side face of the extraction reaction cavity. A pressure reducing device is arranged at the joint of the primary purification device and the extraction device, a liquid conveying pipeline connected with the secondary purification device is arranged at the bottom of the primary purification device, and the secondary purification device comprises a heating source and a purified product collecting cavity; the technical effect is that the purification reaction of organic matters is accelerated by utilizing the catalytic action of supercritical water so as to achieve the final purification purpose.
Description
technical field [0001] The invention relates to the field of supercritical water, in particular to a supercritical water extraction and purification system. Background technique [0002] The supercritical state refers to the state where the pressure and temperature of the substance exceed its critical pressure (PC) and critical temperature (TC) at the same time, or in other words, the relative pressure (P / PC) and relative temperature (T / TC) of the substance are greater than A state of 1 becomes the supercritical state of the substance. [0003] Supercritical fluid refers to a fluid in a supercritical state. At this time, the fluid is in a state where gas and liquid are not separated, there is no obvious gas-liquid interface, and it is neither liquid nor gas. Supercritical fluid has low viscosity, high density, good flow, mass transfer, heat transfer and solubility properties, so it is widely used in energy saving, natural product extraction, polymerization reaction, ultrafi...
