Abstract

The invention relates to the field of chemical separation and bioengineering mechanical devices, and especially relates to a subcritical fluid continuous constant-pressure extraction and separation device system, and an extraction and separation technology thereof. The device system comprises a subcritical fluid medium source, a pressurization subsystem, a continuous extraction subsystem, a separation subsystem having the same step-by-step extraction or extraction stage number with the continuous extraction subsystem, and a pressurized circulation subsystem. The extraction and separation technology enforced by applying the extraction and separation system is operated to make a subcritical fluid or supercritical fluid in a bunker enter the corresponding separation subsystem after the completion of extraction in order to separate, and a discharge valve is periodically opened to discharge the extract separated by the separation subsystem. The device system and the technology have the advantages of high automation degree and reliable running of a device, reasonable process flow, realization of subcritical fluid continuous constant-pressure extraction and separation, energy saving, zeroemission, excellent processability and excellent separation effect.

Description

[0001] 1. Technical field [0002] The invention relates to the fields of chemical separation and bioengineering machinery equipment, in particular to a subcritical fluid continuous isobaric extraction and separation device system and an extraction and separation process. [0003] 2. Technical Background [0004] Subcritical fluid extraction and separation technology is another green chemical technology following supercritical fluid extraction and separation technology, and is being widely used in the field of extraction and separation. However, most of the existing subcritical fluid extraction devices are intermittent devices with quick-opening and sealed structures, which have low production efficiency and high energy consumption; frequent opening of the extractor has low safety and reliability and causes a great loss of extraction fluid, which is a serious constraint. application of this new technology.
