Description
Technical field
The present invention relates to the dyeing installation related in a kind of weaving, dyeing and finishing industry, specifically with the Supercritical carbon dioxide fluid dyeing device of condenser.
Background technology
The traditional dyeing of textiles adds to be that a hygrometric state chemistry adds process, needs to consume a large amount of water resources and chemicals, and produces the colorful wastewater of a large amount of high concentration, high COD, causes serious pollution to its surrounding body and ecological environment.
At present, supercritical CO 2 dyeing technology has obtained interim progress as a kind of novel green dyeing-finishing technology, comparatively ripe to the associating exploratory development of its process conditions, dyeing mechanism and dyeing installation.But because dyeing needs to be realized by special dyeing installation, disposable input cost is higher.In addition, because existing equipment is all single formula device, cause the problem that energy consumption high efficiency is low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, Supercritical carbon dioxide fluid dyeing device with condenser is provided, traditional water bath is replaced to carry out Colour Difference to fabric with supercritical carbon dioxide fluid, dye-free waste water and other discarded object produce, green, environmental protection, cleaner production can be realized, have that cost is low, the feature of economic benefit, obvious environment benefit.
According to the technical scheme provided of the present invention: with the Supercritical carbon dioxide fluid dyeing equipment of condenser, comprise liquid carbon dioxide storage tank, carbon dioxide injection high-pressure pump, heater, dyestuff mixing tank, mixed dye injection high-pressure pump, staining jar, decompression cooler, separating still, condenser, it is characterized in that: described liquid carbon dioxide storage tank be linked in sequence carbon dioxide injection high-pressure pump, heater, dyestuff mixing tank, mixed dye inject high-pressure pump, staining jar, decompression cooler, separating still, condenser.
The present invention compared with prior art, advantage is: (1) is without water, without Wastewater Pollutant generation and discharge, textile enterprise need not pay huge wastewater treatment expense again, has the feature such as ecological, environmental protective and fabric variety wide adaptability, belongs to the dyeing and finishing technology of environment-friendly type; (2) dyeing terminates rear reduction pressure, and carbon dioxide gasifies rapidly, does not thus need to carry out dye post-drying, both shortens technological process, in turn save the energy needed for drying; (3) dyeing speed is fast, and level dyeing and through-dyeing can be good, and the reappearance of dyeing is splendid; (4) carbon dioxide itself nontoxic, tasteless, do not fire, reusable: (5) dyestuff can reuse, without the need to adding the auxiliary agents such as any dispersant, levelling agent and buffer during dyeing, reduce production cost, decrease pollution, there is the plurality of advantages such as energy-saving and emission-reduction, used at dyeing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1. liquid carbon dioxide storage tank, 2. carbon dioxide injection high-pressure pump, 3. heater, 4. dyestuff mixing tank, 5. mixed dye injects high-pressure pump, 6. staining jar, and 7. reduce pressure cooler, 8. separating still, 9. condenser.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, the present invention is with the Supercritical carbon dioxide fluid dyeing equipment of condenser, comprise liquid carbon dioxide storage tank 1, carbon dioxide injection high-pressure pump 2, heater 3, dyestuff mixing tank 4, mixed dye injects high-pressure pump 5, staining jar 6, reduce pressure cooler 7, separating still 8, condenser 9, it is characterized in that: described liquid carbon dioxide storage tank 1 be linked in sequence carbon dioxide injection high-pressure pump 2, heater 3, dyestuff mixing tank 4, mixed dye inject high-pressure pump 5, staining jar 6, decompression cooler 7, separating still 8, condenser 9.
The course of work of the present invention is: by the liquid carbon dioxide that is stored in liquid carbon dioxide storage tank 1 by carbon dioxide injection high-pressure pump 2 by carbon dioxide pressurization to critical pressure (more than 7.38MPa, heater via 3 is by more than its heating temperatures to critical-temperature (31.1 DEG C) again, and carbon dioxide is now supercriticality.Supercritical carbon dioxide fluid enters in the dyestuff mixing tank 4 that dyestuff is housed fully to contact with it and is dissolved, the dyestuff dissolved enters to be equipped with by mixed dye injection high-pressure pump 5 treats that the staining jar 6 of dye textiles realizes dyeing course, after dyeing terminates, supercritical carbon dioxide changes gaseous carbon dioxide into through decompression cooler 7, successfully be separated through separating still 8, be recycled in liquid carbon dioxide storage tank 1 by condenser 9 cooling and participate in dyeing next time.
During dyeing, polyester knitting thing 250 kilograms is loaded in staining jar 6, dye dispersion indigo plant 79 is loaded in dyestuff mixing tank 4, after liquid carbon dioxide carbon dioxide injection high-pressure pump 2 is pressurizeed, heater via 3 heats in rear feeding dyestuff mixing tank 4 again, the dyestuff dissolved injects high-pressure pump 5 by mixed dye and enters the staining jar 6 being equipped with and waiting to contaminate polyester knitting thing, staining jar 6 is warming up to 123 DEG C simultaneously, after pressure reaches 32MPa, by the circulating pump of staining jar 6, supercritical carbon dioxide fluid is circulated in staining jar 6 and carry out dyeing 68 minutes, after having dyeed, make staining jar 6 keep 33MPa pressure and be cooled to 81 DEG C, by the circulating pump of staining jar 6, supercritical carbon dioxide fluid is constantly circulated in staining jar 6, cleaning fiber surface loose colour 62 minutes, after dyeing terminates, supercritical carbon dioxide changes gaseous carbon dioxide into through decompression cooler 7, successfully be separated through separating still 8, be recycled in liquid carbon dioxide storage tank 1 by condenser 9 cooling and participate in dyeing next time, staining jar 6 releases pressure to atmospheric pressure by separating still 8, open staining jar 6, take out the polyester knitting thing contaminated.
By GB/T3921.3-1997 standard, its soaping fastness is tested to the polyester knitting thing after above-mentioned dyeing, test result shows, the soaping fastness of the polyester knitting thing dyeed in supercritical carbon dioxide is 5 grades of soaping fastnesses 3 grades being better than the polyester knitting thing of water-bath dyeing.And the impact of polyester knitting thing at supercritical carbon dioxide and on polyester knitting physical performance when dyeing in a water bath, with the dyeing polyester knitting thing of above-described embodiment and corresponding water-soluble dyeing polyester knitting thing test and comparison, when dyeing in supercritical carbon dioxide, the brute force of polyester knitting thing drops to 10%, be far smaller than polyester knitting thing when water-bath is dyeed 40% strength loss.
As can be seen here, dye-free waste water of the present invention and other discarded object produce, and can realize green, environmental protection, cleaner production, have that cost is low, the feature of economic benefit, obvious environment benefit.
