Description
Technical field
The present invention relates to a kind of supercritical CO 2 dyeing system, relate in particular to the visualization system in a kind of supercritical CO 2 dyeing device.
Background technology
In recent years, the research of waterless staining technique all is being devoted in countries in the world.Along with rapid development of modern science and technology, supercritical fluid technique is subjected to the attention of world many countries day by day, and is applied to numerous industries such as chemical industry, biology, medicine, environmental protection, cosmetics, health, food, printing and dyeing, new material gradually.
As number of patent application: 200510047767.0, title: the process patent of supercritical CO 2 dyeing, and number of patent application: 200520093701.0, title: the dyeing caldron in the supercritical CO 2 dyeing device, all described in this dyeing apparatus, the supercritical carbon dioxide of dissolving dye is finally delivered to the dying operation of realizing textiles in the dyeing caldron.But the dyeing caldron of present supercritical dyeing both domestic and external and dyestuff still can't be realized visual requirement, have the device of minority to adopt noctovisor scan to detect the situation of change of medium in the kettle, can not replace the internal-response state completely.When testing new fabric variety, owing to can't grasp its optimum production technology, need do a large amount of experimental works, wherein the price of dyestuff is very expensive, and a topmost link is exactly to grasp the consumption of dyestuff and fabric ratio in experimentation, fabric is fully painted, guarantee that again dye dosage just.After former experiments tends to occur finish an experimental period, open dyeing caldron and can find that the surface of fabric has the dyestuff adhesion phenomenon to occur, this is normally because the stream of supercritical carbon dioxide amount is low excessively, making dyestuff can not fully be dissolved in when fluid is by the dyestuff still in the supercritical carbon dioxide fluid is being with remaining dye stream in dyeing caldron, thereby the dyestuff adhesion phenomenon appears in the surface that makes the fabric in the dyeing caldron, so just need to continue to increase the stream of supercritical carbon dioxide amount, to guarantee that dyestuff fully is dissolved in supercritical carbon dioxide fluid, also to guarantee the concentration (as abundant dissolving but because concentration is crossed the low fabric inadequate problem of painting that also can occur) of dyestuff dissolving simultaneously, so just need carry out a large amount of repeatedly experiments, and often want tens hours an experimental period, so not only causes temporal waste also to cause the waste of a large amount of dyestuff and fabric simultaneously.So provide a visual environment about dyeing caldron and dyestuff still, be badly in need of being developed with the visualization system of the response situation of thorough medium in the solution reaction kettle.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop the visualization system in a kind of supercritical CO 2 dyeing device.The technical solution adopted in the present invention is as follows:

2) temperature survey and control; Comprise dyeing caldron inlet temperature, dyeing caldron outlet temperature, dyestuff still outlet temperature, dyestuff still inlet temperature, separator inlet temperature, separator outlet temperature, carbon dioxide condensing temperature, ethylene glycol refrigerant temperature, hot oil machine temperature, water heater temperature.Wherein hot oil machine temperature, water heater temperature, ethylene glycol refrigerant temperature are the control displays temperature.
3) flow and level gauging; Be respectively applied for monitoring carbon dioxide flow and tank level.
4) control indicating device: the indication of capital equipment running status is positioned at the instrument board top, and the below is the power supply control and the indication of reporting to the police.
5) safety and interlock: native system has the chain shutdown safety system of a cover high-pressure pump outlet pressure superpressure.
6) computer display control program: can select panel meter or computer to show control by change-over switch, and can preserve easily and print data.
The operation principle that the present invention has the supercritical CO 2 dyeing device of visual control system is:
Liquid carbon dioxide is stored in the circulation basin, by the CO 2 high pressure pump liquid carbon dioxide is forced into more than the critical pressure, by heat exchanger pressurized liquid carbon dioxide is heated to more than the critical point temperature again, makes carbon dioxide be transformed into supercriticality.Postcritical carbon dioxide enters in the dyestuff still of the dyestuff of packing in advance, fully contacts with dyestuff and dissolves; The supercritical carbon dioxide that has the dyestuff composition makes dyestuff enter the inside of textiles by in the dyeing caldron that textiles is housed, and realizes dyeing course.The supercritical carbon dioxide of finishing dyeing course is heated through choke valve decompression, heat exchanger the carbon dioxide solvability is reduced, and impels the dyestuff and the carbon dioxide separation of not dying to the greatest extent, and dyestuff is stayed in the separator; Carbon dioxide then is gasified totally, and returns by condenser liquefaction becoming liquid carbon dioxide and participates in circulation next time in the basin.In the meantime by the visualization device on dyeing caldron and the dyestuff still, can observe and dye the whole process that combines with outer dyeing technique and dyestuff dissolving, process of flowing in the fabric, realized the visual of supercritical dyeing process, make dyestuff from be dissolved into a dyeing and finishing process, be in fully under the range estimation condition, for grasping supercritical CO
2The principle that balances each other provides good observation condition.
Instantiation is as follows: put into the 20g polyester cotton in dyeing caldron, during the 2g dyestuff, the temperature of setting by control system is 110 ℃ in the dyestuff still, and pressure is 25MPa, and flow velocity is greater than 200ml/min, and dyeing time is 2 hours.By oil bath heating, the force (forcing) pump pressurization, intrasystem temperature, pressure raise gradually, by sensor, the camera in dyeing caldron, the dyestuff still, the real time data of system are passed to computer.By being presented on the picture on the display, we observe the adhesion amount of fabric face dyestuff in the dyeing caldron, if the excessive fabric face that covers of adhesion amount, influence fabric on dye, to continue pressurization so, if the pressure that pressure is set at the beginning greater than our system, force (forcing) pump will stop voltage supply automatically, and temperature, flow velocity also can be realized automatic control as a same reason.When the picture of observation shows that dyestuff still and dyeing caldron do not have excess dye,, also this device can be stopped although not reaching dyeing time.All dissolve because obtain dyestuff according to observation, on the process of dying finish.Can save a large amount of time like this.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
