A kind of supercritical carbon dioxide fluid extraction device

Abstract

The invention discloses a supercritical carbon dioxide fluid extraction device. The supercritical carbon dioxide fluid extraction device structurally comprises a cover plate, an emergency control button, an extraction tank, a water tank, a data meter, a data control button and an internal actuator, wherein the cover plate is movably connected to the upper end of the extraction tank; the emergencycontrol button is mounted on the side surface of the extraction tank; the water tank, the data meter and the data control button are adjacent; the water tank is embedded in a concave port of the extraction tank; the data meter and the data control button are mounted on the front side surface of the extraction tank, and the data meter is connected with the data control button. When materials are stored and mounted before extraction, firm mounting is indicated through prompt sound for mounting completion, horizontal position displayed after mounting indicates correct mounting, and incorrect mounting conditions are reduced greatly; insufficiency of internally stored water can be found timely through alarm prompt during extraction, water storage is performed timely, raw material scrapping or equipment failure is avoided, extraction progress is accelerated, operation cost is reduced, and time and labor are saved.

Description

Technical field [0001] The present invention relates to the field of the extraction device, in particular a supercritical carbon dioxide extraction apparatus. Background technique [0002] As the ambient temperature and pressure changes, any supercritical carbon dioxide extraction apparatus substances there are three phases - gas, liquid, solid, three-phase equilibrium point to coexist called triple point / liquid, gas two-phase interface disappears state point called the supercritical point. Temperature and pressure at the critical point is called the critical temperature and critical pressure, the pressure and temperature of its critical point different species varies. It refers to supercritical fluid temperature and pressure higher than its critical point of a fluid, used to prepare a supercritical fluid carbon dioxide, ammonia, ethylene, propane, propylene, water and the like. When the object is in a supercritical state, since the gas-liquid two-phase nature of the very simil...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a supercritical carbon dioxide fluid extraction device to solve the problem of incorrect installation or inability to be detected in time through an alarm when the material is stored and installed before extraction. Insufficient internal water storage, unable to store water in time, may lead to waste of raw materials or equipment failure, not only time-consuming and labor-intensive, but also affect the extraction progress, increasing the problem of operating costs
