Abstract

The invention discloses an efficient separation device for supercritical extraction, belongs to the technical field of supercritical extraction, and aims to realize that when a driving motor drives threaded blades to separate mixed substances, a magnetic refrigeration block absorbs heat generated by the driving motor, drives hot air to quickly flow upwards, accelerates heat dissipation and improves the separation efficiency. Meanwhile, the ammonium chloride powder and the barium hydroxide octahydrate powder are mixed to react and absorb heat for cooling, so that multidirectional absorption and dissipation of heat are realized, the cooling effect is achieved, the influence of overhigh temperature on separation of mixed substances in the separation tank body is avoided, the separation effect is enhanced, oxygen in the separation tank body is consumed by the palladium carbon fiber oxygen consumption agent, and the separation efficiency is improved. The palladium-carbon fiber oxygen-consuming agent is added to reduce the content of the palladium-carbon fiber oxygen-consuming agent, so that the mixed substance is not easy to oxidize in the separation process, the palladium-carbon fiber oxygen-consuming agent is rapidly and fully contacted with oxygen under the pushing of the elastic hemispherical membrane, the oxygen consumption is more rapid and comprehensive, the oxygen-consuming effect is improved, the possibility of oxidation of the mixed substance is further reduced, and the separation quality is improved.

Description

technical field [0001] The invention relates to the technical field of supercritical extraction, in particular to a high-efficiency separation device for supercritical extraction. Background technique [0002] Supercritical is a supercritical fluid, which is a state of matter that is neither gaseous nor liquid between gas and liquid. This substance can only exist when its temperature and pressure exceed the critical point, and its viscosity is relatively high. Close to gas, supercritical carbon dioxide fluid extraction is to contact the supercritical carbon dioxide fluid with the material to be separated in a supercritical state, so that it can selectively extract the components of polarity, boiling point and molecular weight in sequence , as an environment-friendly technology, supercritical extraction has attracted more and more attention because of its unique physical and chemical properties and many advantages, and its application has become more and more extensive.
