Extraction separator and manufacturing method thereof

Abstract

The invention discloses an extraction separator and a manufacturing method thereof. When the extraction separator is manufactured, an air flow guide pipe is arranged at a process fluid inlet of the extraction separator, and process fluid enters in an inner cavity of a high-pressure kettle body of the extraction separator through the air flow guide pipe; then the flow direction of the process fluid is changed, and the process fluid flows along the peripheral direction of the inner cavity of the high-pressure kettle body and sprayed out of the air flow guide pipe along the tangential direction of the circumference. The invention thoroughly changes the flow direction of the high-pressure process fluid for entering the extraction separator, effectively avoids the blowing to the stored products at the bottom of the extraction separator of an axial air entering mode, improves the separating capacity of a supercritical extraction device, ensures the normal service life of each component in the supercritical extraction device, keeps the due extraction capacity of the process fluid and has the advantages of good separating effect, low operating cost and high working efficiency.

Description

technical field [0001] The invention relates to an extraction separator and a manufacturing method thereof, belonging to the technical field of supercritical fluid extraction devices. Background technique [0002] In industrialized supercritical fluid extraction devices, extraction separators are commonly used to separate products. The design and manufacture of extraction separators refer to the relevant requirements in the national standard GB150 and "Supervision Regulations on Safety Technology for Pressure Vessels". At present, all types of extraction separators designed and manufactured at home and abroad adopt axial air intake. There are many avoidances in this air intake method: a. High-pressure strong airflow enters the container, and some products accumulated at the bottom of the separator after separation It is blown into a mist of ultrafine particles and flows out of the separator with the process medium, which affects the separation effect of the product and makes...

Problems solved by technology

c. The quality of the process medium decreases, which affects its extraction capacity

The extraction ability of the process medium depends on its purity. The products blown into ultra-fine particles are mixed in the process medium, which reduces the purity of the process medium and the extraction ability, which ultimately affects the extraction ability of the supercritical extraction device.

Therefore the use effect of existing extraction separator is still not ideal enough
