Description
Technical field
The present invention relates to the post processing field of knitting fabric, in particular it relates to dark polyester knitting thing Efficient Ring in one kind
Protect dyeing post-processing approach.
Background technology
Dark in terylene, traditional reduction cleaning technique includes：Reduction cleaning and reduction under acidic conditions are clear under alkalescence condition
Wash.Convention acidic reduction cleaning, is to add caustic soda and sodium hydrosulfite to be processed toward the raffinate containing not upper dye, and this mode is needed
Want more reducing agent.Therefore after mostly being discharged water by dyeing, toward interior input caustic soda and the sodium hydrosulfite of dye vat, using the strong of sodium hydrosulfite
Reproducibility cleans the dyestuff (loose colour) for sticking to terylene, vinegar ester and its blend fabric surface in the basic conditions.
The process cycle of the post processing is long, power consumption is high, and low production efficiency and production cost are high, after the auxiliary agent of application is also aggravated
Continuous treatment pressure of sewage, and cause larger energy waste.
Ensure dyeing quality under conditions of, how reducing energy consumption, reduce blowdown, be each textile printing and dyeing enterprises common concern
Major issue.Cleaning has reduction cleaning, high temperature to soap after traditional disperse dyeing, and its process cycle is long, power consumption
Height, production efficiency and production cost are all restricted, and the auxiliary agent of application also aggravates follow-up treatment pressure of sewage.
The content of the invention
It is contemplated that overcoming drawbacks described above, the production technology time is saved by using one kind, reducing energy consumption, without change
Learn auxiliary agent, reduces cost and saving production technology time of follow-up treatment pressure of sewage can be mitigated, reducing energy consumption, without chemistry
Auxiliary agent, reduces cost and can mitigate follow-up treatment pressure of sewage.
Dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is characterised in that：
In dyeing temperature-fall period, by discharging high-temperature dyeing raffinate under high pressure, using the thermal energy conduction of raffinate so that injection in toward dye vat
Clear water be able to protect mild heat, and temperature can be reduced to 70 DEG C and once discharges by the dyeing residual night discharged；
Wherein, the thermal energy conduction process of above-mentioned utilization raffinate is realized using heat exchanger；
Above-mentioned heat exchanger is made up of water inlet component and outlet component；
Above-mentioned water inlet component and outlet component interval setting；
Chicane is provided with above-mentioned outlet component.
Further, dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is special
Levy and be：
The technique of above-mentioned post processing is：
After rinse water is injected in dye vat, after being kept for 20-45 minutes at 130 DEG C, the temperature with 2 DEG C per minute is lowered the temperature
1-10 minutes is incubated after to 80 DEG C, rinse water is discharged.
Further, dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is special
Levy and be：
Above-mentioned water inlet component is made up of the water inlet plate of at least 15；
Above-mentioned plate is even curface for two sides.
Further, dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is special
Levy and be：
Above-mentioned outlet component is made up of the water outlet plate of at least 15；
Above-mentioned water outlet plate surface is the surface of out-of-flatness.
Further, dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is special
Levy and be：
Chicane is provided with above-mentioned water outlet plate；
Above-mentioned chicane is the fluid passage being made up of at least 10 runners tortuous each other.
Further, dark polyester knitting thing high-efficiency environment friendly dyeing post-processing approach in one kind that the present invention is provided, it is special
Levy and be：
Above-mentioned fluid passage externally protrudes out in the surface of water outlet plate, forms the surface texture of out-of-flatness.
Effect of the invention and effect
This can both reach the dye of traditional handicraft the invention provides a kind of low-carbon (LC) cleaning method of environmental protection, adopting said method
Color effect (such as wash water, bleed fastness index), time-consuming, improve production efficiency and energy-saving and environmental protection.
The non-auxiliary agent cleaning of the present invention, is, by discharging high-temperature dyeing raffinate under high pressure, to utilize in dyeing temperature-fall period
The thermal energy conduction of raffinate so that the clear water of injection is heated in toward dye vat, and the dyeing residual liquid discharged can reduce temperature
Discharged to less than 60 DEG C.The clear water of injection in toward dye vat, obtains mixing with dye liquor in dye vat after heat energy heats up, and can both reduce temperature
Degree, be not in again because inject coolant-temperature gage it is too low lower the temperature it is too fast.This water washing technology using fabric in temperature-fall period progressively
Cold events, temperature-fall period injected clear water can constantly reduce the dyestuff of dye liquor, assistant concentration in dye vat, while cleaning fabric face
Remaining loose colour, lifted fabric color fastness.This technique also shortens or reduces dyeing aftertreatment technology simultaneously, reduces or keeps away
The use of unburned alkali and sodium hydrosulfite, also mitigates follow-up sewage disposal.
This high temperature wash water mode of the present invention is typically carried out using following heat-exchangers of the plate type.This plate type heat exchanger be by
Water inlet plate and water outlet plate in the middle of fixed pressure plate, movable pressure plate, are then pressed from both sides in the form of being superimposed with fishbolt
Tightly form, due to being provided with the passage of convolution in water outlet plate, when water outlet flow it is elongated while, be water inlet by the projection on surface
Heated, the process of the heating is compared than conventional shell-and-tube or plate type heat exchanger, due to the increase of its surface area for heating,
In the case of same pump power consumption, its heat transfer coefficient will be higher by a lot.
Brief description of the drawings
The aftertreatment technology figure of accompanying drawing 1, the present embodiment；
The water inlet component of the heat exchanger that accompanying drawing 2, the present embodiment is related to and the structural representation of outlet component.
Specific embodiment
As shown in figure 1, discharging high-temperature dyeing residual night under in dyeing temperature-fall period by high pressure, passed using the heat energy at residual night
Lead so that the clear water of injection is heated in toward dye vat, and temperature can be reduced to 70 DEG C and once arranged by the dyeing residual night discharged
Go out.
The thermal energy conduction process of above-mentioned utilization raffinate, is realized using heat exchanger；
As shown in Fig. 2 in the present embodiment, the heat exchanger is made up of some water inlet plates 100 and water outlet plate 200；
Some water inlet plates 100 and the water outlet plates 200 interval setting each other；Plate 100 and water outlet plate 200 will be intake to be superimposed
Then form is stepped up to form in the middle of fixed pressure plate and movable pressure plate with clamp stud.
Chicane 210 is provided with the water outlet plate 200, the chicane 210 is fluid passage, during use,
Pass through discharge water, the chicane 210 is the curved moulding of zigzag 18, one part is arranged on the mainboard of water outlet plate 200,
The width of water outlet plate 200 is had a diameter larger than, the both sides of water outlet plate 200 can be protruded from, water stream channel is formed, due to the passage
The flow of energy increased water flow, so, the process and area of heating can be increased, improve the efficiency of heat exchange.
