Abstract

The invention discloses a self-adaptive control device for a supercritical extraction and separation device, and belongs to the field of supercritical extraction and separation devices. According to the scheme, the self-adaptive control device for the supercritical extraction and separation device can control the pressure intensity in a separation environment through an Internet of Things technology so that the crystallization rate of the target crystal is controlled, the target crystal is not easy to precipitate too slowly, the target crystal grows too slowly, and the target crystal is not easy to precipitate too fast to generate violent growth to cause excessive dispersion of the target crystal. Meanwhile, the capture fiber cluster is arranged in the separation kettle main body so that target crystals are easily separated out and adsorbed on elastic fiber individuals of the capture fiber cluster, and the separated target crystals can grow at a pre-designed specified position; meanwhile, a collecting disc matched with the captured fiber cluster is arranged in the separation kettle main body, subsequent collection and purification of target crystals are facilitated, and the separation efficiency is improved.

Description

technical field

[0001] The invention relates to the field of supercritical extraction and separation devices, and more specifically relates to an adaptive control device for supercritical extraction and separation devices. 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. A supercritical fluid has a higher density, similar to a liquid, and its viscosity is closer to that of a gas. Therefore, supercritical fluid is a very ideal extraction agent. The principle of supercritical CO2 fluid extraction (SFE) separation process is to use the relationship between the dissolving ability of supercritical fluid and its density, that is, the relationship between the dissolving ability of supercritical fluid by pressure and temperature carried out by influence. In the supercritical state, the ...
