Abstract

The invention discloses an intelligent multifunctional device for high-pressure supercritical fluid, and relates to a supercritical fluid device. A pressure source (1) of the device is connected with a kettle body part (2) which is connected with the upper end of a cold-hot circulation part (3), a booster pump (4) is arranged inside the cold-hot circulation part (3), the lower end of the cold-hot circulation part (3) is connected with the upper end of a multifunctional high-pressure treatment system (5) which is connected with an intelligent control display part (6), and the kettle body part (2) is also connected with the intelligent control display part (6). The intelligent multifunctional device has wide temperature and pressure control range, can produce various supercritical organic medium fluids, and has high working efficiency.

Description

Technical field: [0001] The invention relates to a supercritical fluid device, in particular to an intelligent high-pressure supercritical fluid multifunctional device. Background technique: [0002] A supercritical fluid is a fluid whose temperature and pressure are both higher than a critical value, that is, a gas compressed to a density close to that of a liquid. In the supercritical state, the gas-liquid two-phase properties are so close that they cannot be distinguished, so they are called supercritical fluids. Many physical and chemical properties of supercritical fluids are between those of gases and liquids, and have the advantages of both. Supercritical fluid is a fluid whose thermodynamic state is above the critical point. The critical point is the state point where the gas-liquid interface just disappears. Supercritical fluid has very unique physical and chemical properties. Its density is close to that of liquid, its viscosity is close to that of gas, and It ha...
