High-pressure fluid extraction separator

Abstract

The invention discloses a high-pressure fluid extraction separator, which comprises a kettle body, a kettle cover and a jacket wrapping the outer wall of the kettle body; a water inlet and a water outlet are formed in the jacket, an air outlet and an air inlet provided with an air inlet pipe are formed in the two sides of the upper portion of the kettle body respectively, one end of the air inletpipe stretches out of the kettle body, and the other end of the air inlet pipe stretches into the kettle body. A liquid collector is connected to the bottom of the kettle body, a through hole and a connecting pipe communicated with the through hole are arranged at the bottom of the liquid collector, and a hot water pipe is inserted into the liquid collector and connected with the liquid collectorthrough a connecting part, wherein a hot water inlet end and a hot water outlet end of the hot water pipe penetrate through the through hole from the inside of the liquid collector and extend to the outside of the liquid collector. According to the present invention, the extract is accumulated in the liquid collector through the liquid collector and is heated by the hot water pipe, such that the temperature of the extract converted into the easily-flowing state is effectively controlled, the energy consumption loss caused by the use of the jacket to heat the extract is avoided; therefore, theseparation efficiency and the separation effect are improved, the extraction medium (solvent) loss is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of extraction and separation equipment, in particular to a high-pressure fluid extraction separator. Background technique [0002] Supercritical fluid extraction technology is a new type of extraction and separation technology developed in recent decades. Supercritical fluid refers to a high-pressure fluid whose temperature and pressure are higher than the critical temperature and critical pressure, and it has excellent solvency. As a new extraction and separation technology, supercritical fluid extraction technology has its advantages in high value-added, heat-sensitivity, extraction and separation of difficult-to-separate substances, and removal of trace impurities. It is an efficient and green chemical industry. technology. [0003] Supercritical fluid extraction mainly includes two processes of extraction and separation. The extraction process is that the supercritical fluid acts as the extraction medi...

AI Technical Summary

Problems solved by technology

When the device is used to separate the supercritical fluid and the extracted substance, when the extracted substance has the characteristics of high viscosity such as paste and crystal under the condition of low temperature, the extracted substance separated by the extraction separator is accumulated in the When the bottom of the kettle body is released from the product outlet, it is necessary to heat the extracted substance into a liquid state to avoid the viscous extract from adhering to the inner wall of the kettle body, and when the extracted substance is discharged from the discharge pipe, the discharge pipe will also be damaged. If the jacket is used to directly heat the extracted substance, it will lead to large heating energy consumption and large temperature difference, and the heating temperature is not easy to control, which increases the separation cost and reduces the separation effect

[0005] Therefore, there is an urgent need to provide a high-pressure fluid extraction separator to solve the problems of poor separation effect, large consumption of extraction medium (or solvent), especially the poor separation effect of viscous extracted substances, and the problem that the product cannot be discharged cleanly.
