Description
The present invention relates to a kind of commercial scale supercritical carbon dioxide extraction equipment, particularly relate to a kind of efficient, energy-conservation supercritical carbon dioxide extraction apparatus.
Present supercritical carbon dioxide extraction apparatus, what adopted is single still or two still batch (-type), also has multi-still continuous.But their weak point is: must be carbon dioxide emptying more than the 5Mpa being deposited in pressure at least in the extraction kettle after the balance before discharging, available carbon dioxide is slatterned, energy consumption be big.
The object of the present invention is to provide a kind of high efficiency that has, the supercritical carbon dioxide device of low energy consumption.
In order to achieve the above object, the technical solution used in the present invention is: carbon dioxide steel cylinder and blender, ice chest, storage tank, the carbon dioxide plunger displacement pump is together in series, carbon dioxide plunger delivery side of pump and each extraction kettle bottom inlet are connected in parallel, heat exchangers in series all between carbon dioxide plunger displacement pump and the extraction kettle, the both sides, upper end of each extraction kettle have two outlets respectively, an outlet is connected with the separating still import, constitute and separate pipeline, separate on the pipeline and also be provided with Pressure gauge and safety valve, another outlet is passed through back only to be connected with device for drying and filtering, constitute supply air line, the supply air line of each extraction kettle all is connected with next extraction kettle bottom inlet, first separating still upper end exports in second separating still upper end import and connects, second separating still upper end outlet passed through back to end valve and is connected with device for drying and filtering, and separating still lower end material outlet links to each other with receiver.
Compare with prior art, the present invention has following advantage:
1, energy serialization production is raised the efficiency;
2, can save carbon dioxide, the big more saving carbon dioxide of extraction kettle volume is many more.
As shown in Figure 1, four extraction kettles are divided into two groups, promptly 11,12 is first group, and 13,14 is second group, but two still series and parallel switchover operations of every group.First group 11,12 parallel runnings; Open stop valve 1,7,8,24,26 and control valve 27, remaining valve closing, at this moment carbon dioxide enters in extraction kettle 11,12 and the separating still 28,31 immediately in the steel cylinder, get rid of the air in each still simultaneously, after treating pressure balance, close control valve 27, open carbon dioxide plunger displacement pump 5, condition such as extraction temperature, pressure is decided on different products, concrete operating path is: the carbon dioxide in the steel cylinder 33 enters in the extraction kettle 11,12 through blender 2, ice chest 3, storage tank 4, heat exchanger 5 under the effect of plunger displacement pump 5.When extraction kettle pressure reaches setting pressure, open control valve 27, the beginning dynamic operation enters in the separating still 28,31 supercritical carbon dioxide fluid and solute and separates, and the carbon dioxide after the separation enters device for drying and filtering 35 through valve 34 time only and anhydrates and recycle after part.After running to setting-up time, the big pump 5 of closing carbon dioxide plunger is emitted product from receiver 29,32, and extraction finishes.Second group 13,14 parallel runnings; Close stop valve 1, cut off the steel cylinder air supply source, close stop valve 7,8,24,26 and control valve 27, open stop valve 15,16,17, extraction kettle 11, carbon dioxide in 12 is put into extraction kettle 13,14 li, air in the still of emptying simultaneously, after treating 4 still pressure balances, close stop valve 15,16,17, open stop valve 9,10,23,25, open carbon dioxide plunger displacement pump 5, extraction kettle 11,12 carbon dioxide is as source of the gas, squeeze into extraction kettle 13,14 li, open stop valve 20,22, with control valve 27 control extraction kettles 13,14 pressure, when extraction kettle 11, when 12 pressure drop to 3Mpa, extraction kettle 11, carbon dioxide in 12 can not utilize again, closes stop valve 23,25, switch to steel cylinder 33 air feed.Bleed off the residual air in the extraction kettle 11,12 then, shed waste residue, the virgin material of packing into is stand-by.After running to setting-up time, closing carbon dioxide plunger displacement pump 5 is emitted product from receiver 29,32, and extraction finishes.Switch back to first sets in parallel operation; Close stop valve 1,9,10,22 and control valve 27, open stop valve 20,22,15,16, extraction kettle 13, carbon dioxide in 14 is put into extraction kettle 11,12 li, air in the still of emptying simultaneously, after treating 4 still pressure balances, close stop valve 20,22,15,16, open stop valve 7,8,19,21, open carbon dioxide plunger displacement pump 5, extraction kettle 13,14 carbon dioxide is as source of the gas, squeeze into extraction kettle 11,12 li, open stop valve 24,26, with control valve 27 control extraction kettles 11,12 pressure is when extraction kettle 13, when 14 pressure drop to 3Pma, extraction kettle 13, carbon dioxide in 14 can not utilize again, close stop valve 19,21, can change to steel cylinder 33 air feed, bleed off extraction kettle 13 then, residual air in 14, shed waste residue, the virgin material of packing into is stand-by.After running to setting-up time, the closing carbon dioxide plunger displacement pump is emitted product from receiver 29,32, and extraction finishes.Operation is later on all undertaken by above-mentioned method of operating.
