The device used for dyeing of the supercritical carbon dioxide fluid comprises a liquid carbon dioxide storage tank, a carbon dioxide injection high-pressure pump, a heater, a dye mixing tank, a mixed dye injection high-pressure pump, a dyeing jar, a decompression and cooling device and a separation kettle. The device used for dyeing of the supercritical carbon dioxide fluid is characterized in that the liquid carbon dioxide storage tank is connected with the carbon dioxide injection high-pressure pump, the heater, the dye mixing tank, the mixed dye injection high-pressure pump, the dyeing jar, the decompression and cooling device and the separation kettle in sequence. The device used for dyeing of the supercritical carbon dioxide fluid has the advantages that due to the fact that no water is used, no waste water is generated or discharged, a textile enterprise does not need to pay a huge amount of money for waste water treatment, ecological environmental protection is achieved, the adaptability of textile fabric variety is strong, the dyeing speed is high, level dyeing performance and thorough dyeing performance are good, the dyeing reproducibility is quite excellent, dye can be used repeatedly, addition agents such as a dispersing agent, a leveling agent and a buffering agent do not need to be added during dyeing, production cost is reduced, pollution is reduced, energy is saved, and emission is reduced.
Description
Technical field
The utility model relates to the dyeing installation of using in a kind of weaving, dyeing and finishing industry, more particularly, relates to a kind of special equipment of supercritical carbon dioxide fluid dyeing.
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 resource and chemicals, and produces the colorful wastewater of a large amount of high concentrations, high COD, and serious pollution has been caused in its peripheral waters and ecological environment.
Summary of the invention
The utility model is for the problems referred to above, a kind of special equipment of supercritical carbon dioxide fluid dyeing is provided, replace traditional water bath to the fabric processing of dyeing with supercritical carbon dioxide fluid, due to dye-free waste water and other generation of waste materials, can thoroughly realize green, environmental protection, clean production, have advantages of and save water and energy simultaneously.
The technical solution of the utility model is: a kind of special equipment of supercritical carbon dioxide fluid dyeing, comprise that liquid carbon dioxide storage tank, carbon dioxide injection high-pressure pump, heater, dyestuff mixing tank, mixed dye inject high-pressure pump, staining jar, decompression cooler, separating still, is characterized in that: be linked in sequence carbon dioxide injection high-pressure pump, heater, dyestuff mixing tank, mixed dye of described liquid carbon dioxide storage tank injects high-pressure pump, staining jar, decompression cooler, separating still.
The beneficial effects of the utility model are: with traditional water dyeing technique, compare, the supercritical carbon dioxide fluid dyeing machine has the following advantages: (1) not water, without contaminated wastewater deposits yields and discharging, textile enterprise needn't pay huge wastewater treatment expense again, have the characteristics such as ecological, environmental protective and fabric variety wide adaptability, belong to the dyeing and finishing technology of environment-friendly type; (2) reduce pressure after dyeing finishes, carbon dioxide gasifies rapidly, thereby does not need to dye post-drying, has both shortened technological process, has saved again the required energy of 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, need not to add the auxiliary agents such as any dispersant, levelling agent and buffer during dyeing, reduced production cost, reduced pollution, have the plurality of advantages such as energy-saving and emission-reduction, at dyeing, used.
Description of drawings
Fig. 1 is apparatus structure schematic diagram of the present utility model.
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, 7. decompression cooler, 8. separating still.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of special equipment of supercritical carbon dioxide fluid dyeing in the utility model, comprise that liquid carbon dioxide storage tank 1, 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, is characterized in that: be linked in sequence carbon dioxide injection high-pressure pump 2, heater 3, dyestuff mixing tank 4, mixed dye of described liquid carbon dioxide storage tank 1 injects high-pressure pump 5, staining jar 6, decompression cooler 7, separating still 8.
The course of work of the present utility model is: the liquid carbon dioxide that will be stored in liquid carbon dioxide storage tank 1 is forced into critical pressure (more than 7.38MPa by carbon dioxide injection high-pressure pump 2 with carbon dioxide, more than heater via 3 was heated to critical-temperature (31.1 ℃) with its temperature again, the carbon dioxide of this moment was supercriticality.Supercritical carbon dioxide fluid enters in the dyestuff mixing tank 4 that dyestuff is housed and fully contacts its dissolving with it, the dyestuff that dissolves injects high-pressure pump 5 by mixed dye and enters the staining jar 6 that textiles to be dyed is housed and realize dyeing course, after dyeing finishes, supercritical carbon dioxide changes gaseous carbon dioxide into through decompression cooler 7, successfully separate through separating still 8, participate in dyeing next time, recycle.
during dyeing, the polyester knitting thing of packing in staining jar 6, the dyestuff Disperse Blue-79 of packing in dyestuff mixing tank 4, after liquid carbon dioxide is pressurizeed with carbon dioxide injection high-pressure pump 2, send in dyestuff mixing tank 4 after heater via 3 heating again, the dyestuff that dissolves injects high-pressure pump 5 by mixed dye and enters the staining jar 6 that polyester knitting thing to be dyed is housed, staining jar 6 is warming up to 125 ℃ simultaneously, after pressure reaches 35MPa, circulating pump by staining jar 6 makes supercritical carbon dioxide fluid circulate and dye 70 minutes in staining jar 6, after dyeing is completed, make staining jar 6 keep 35MPa pressure and be cooled to 85 ℃, circulating pump by staining jar 6 constantly circulates supercritical carbon dioxide fluid in staining jar 6, cleaned the fiber surface loose colour 65 minutes, after dyeing finishes, supercritical carbon dioxide changes gaseous carbon dioxide into through decompression cooler 7, successfully separate through separating still 8, participate in dyeing next time, recycle, staining jar 6 releases pressure to atmospheric pressure by separating still 8, open staining jar 6, take out the polyester knitting thing that has dyed.
Polyester knitting thing by the GB/T3921.3-1997 standard after to above-mentioned dyeing is tested its soaping fastness, test result shows, the soaping fastness of the polyester knitting thing that dyes in supercritical carbon dioxide is 3 grades of the soaping fastnesses of 5 grades of polyester knitting things that are better than water-bath dyeing.And the polyester knitting thing is in supercritical carbon dioxide and when dyeing impact on the polyester knitting physical performance in water-bath, dyeing polyester knitting thing and corresponding water-soluble dyeing polyester knitting thing test with above-described embodiment are compared, while dyeing in supercritical carbon dioxide, the brute force of polyester knitting thing drops to 10%, is far smaller than polyester knitting thing strength loss of 40% when water-bath is dyeed.
This shows, the utility model not water, without contaminated wastewater deposits yields and discharging, textile enterprise needn't pay huge wastewater treatment expense again, has the characteristics such as ecological, environmental protective and fabric variety wide adaptability.
