Abstract
A multipurpose supercritical CO2 extraction equipment has three sets of flow direction valves (four in number) and one serial-parallel connection valve, and features that the flow direction valve controls the flow direction of CO2, that is to flow forwards or reversely, for adapting to the need of multiple purposes, and the serial-parallel connection valve connects three extraction stills serially or perallelly in operation. Serial connection will result in high extraction rate, whereas parallel connection will double and redouble the yield.
Description
The present invention relates to a kind of supercritical extraction process, particularly a kind of Multifunctional-supercritical CO 2 extraction technology.
Supercritical extract mostly is to adopt CO in the prior art
2The extraction process of (forward) from bottom to top, single still or two still intermittently operated, not only energy consumption is big, efficient is low, and some application is restricted.
The purpose of this invention is to provide a kind of Multifunctional-supercritical CO 2 extraction technology,, enlarge the range of application of supercritical extract to overcome above-mentioned shortcoming.This flow process is made up of every group of 4 flow valves and 1 connection in series-parallel valve, is characterized in carbon dioxide (CO
2) can forward and reversely flow, but 3 extraction kettle connection in series-parallel operations.Its advantage is that the former enlarges application surface, and extraction efficiency improved when the latter connected, and extraction quantity is multiplied when in parallel.
Embodiment of the present invention are as follows:
Shown in Fig. 1 Multifunctional-supercritical CO 2 extraction technology flow chart, first group of flow valves V10, V11, V12, V13, connection in series-parallel valve V7 and relevant stream valve V4, the extractor valve V22 of control extraction kettle E1.The flow valves, the connection in series-parallel valve that similarly also have second group, the 3rd group control E2, E3.As long as the open and close with 2 valves on the flow valves diagonal just can change CO
2The flow direction, as long as the connection in series-parallel valve is carried out open and close, the series and parallel in twos that just can carry out 3 extraction kettles moves.At first with charging feedstock in the barrel, place extraction kettle by quick-actuating closure during enforcement, heater H 1, H2 heating make extraction kettle and separating still temperature reach setting value, and refrigerator H3, H4 refrigeration makes CO
2Storage tank T, refrigerator C reduce to design temperature.Open CO
2The source valve is supplied with storage tank CO
2, start the K compressor, make liquid CO among the condenser C
2Pressure is 8～12Mpa; Then, open that high-pressure pump P1, P2 pressurization extracts, separation, CO
2Circulation.
Advantage of the present invention: 1, flow sheet equipment is simple, only increases valve, pipeline, just intermittence production can be become serialization production.2, can be used for some special extractions, application surface is enlarged.Extraction yield improves when 3, connecting, and extraction quantity is multiplied when in parallel.Energy-conservation, synergy is very remarkable.
Following preference describes the control operation of flow valves, connection in series-parallel valve in detail in conjunction with flow chart: 1, for general application, can adopt CO
2Forward (from bottom to top) flows, extraction kettle connection in series-parallel operation: 1.1, forward series operation
Open V11, V12 on the flow valves diagonal, V15, V16, V19, V20 valve are opened connection in series-parallel valve V7 again and relevant V4, V23 carry out crosscurrent extraction; Close V4, V23 successively, open V8, V5, V24 and carry out E2, E3 extraction, close V5, V24, open V9, V6, V22, carry out E3, E1 extraction.And the like, carry out two still series connection continuous extractions.
Or open V7, V8 valve and V4, V24 valve, carry out E1, E2, E3 three still series operations.
Series operation can make extraction yield obviously improve.1.2, the forward parallel running
Flow valves is constant, closes connection in series-parallel valve V7, V8, V9, opens V4, V22, V5, V23, and then extraction kettle E1, E2 can carry out the parallel connection extraction.Close V4, V22, open V6, V24 and can carry out E2, E3 extraction in parallel; Close V6, V24, open V4, V22 and can carry out E3, E1 extraction in parallel.And the like, carry out the continuous extraction in parallel of two stills; Or opening V4, V22, V5, V23, V6, V24 can carry out E1, E2, E3 three still parallel runnings.
Parallel running can make extracted products output be multiplied.2, for special applications, as extract strong polar substances, can adopt CO
2Oppositely (from top to bottom) flow the operation of extraction kettle series and parallel.2.1, differential concatenation operation
Open V10, V13 on the flow valves diagonal, V14, V17, V18, V21 valve and when opening connection in series-parallel valve V7, V8, V9 successively, but then extraction kettle E1, E2, E2, E3, E3, the continuous extraction of E1 differential concatenation, or open V7, V8 valve simultaneously, then E1, E2, E3 three still series operations (similar 1.1).2.2, reverse parallel connection operation
Flow valves is constant, closes connection in series-parallel valve V7, V8, V9, then extraction kettle E1, E2, E2, E3, E3, the continuous extraction of E1 reverse parallel connection, or E1, E2, E3 three still parallel runnings (similar 1.2).
Fig. 1, Multifunctional-supercritical CO 2 extraction flow chart.The component names of each code name is as follows among the figure:
A1, A2, B1, B2 separating still, C condenser, E1, E2, E3 extraction kettle, H1, H2 heater, H3, H4 refrigerator, the K diaphragm compressor, M modifier groove, P1, P2 high-pressure pump, P3 modifier pump, T carbon dioxide storage tank, V4～V6 high pressure stream valve, V7～V9 connection in series-parallel valve, V10～V13, V14～V17, three groups of flow valves of V18～V21, V22～V24 extractor valve, the V25 adjustable needle valve, V26～V28 CO
