Abstract
Based on available dyeing machine, the present invention modifies the heat exchanger and exhausting parts of dyeing machine and combines its direct cooling and cleaning parts. The present invention can overcome the demerits of available technology and reach the aims of saving energy, lowering cost and raising product quality.
Description
What the present invention relates to is direct cooling and cleaning method for dyeing machine, concretely, the present invention relates to be with the direct cooling of dyeing machine with clean a kind of method that merges; The present invention is the improvement of corresponding exhaust dyeing peripheral devices.
The heating of the exhaust dyeing machine of prior art or the type of cooling are to utilize the indirect heat transfer mode of shell-and-tube exchanger to reach needed dyeing temperature, the indirect mode is for dyeing course, it is the bath of dye liquor ratio that can not influence dyeing course that a very important advantage is arranged, therefore in dyeing course, for fixing bath raio, generally all adopt the indirect mode to come heating-cooling; It is lower that yet the shortcoming of indirect mode is a heat exchanger effectiveness; Therefore with processes such as the irrelevant cooling of bath raio and cleaning in, the purpose of utilizing the indirect mode to reach cooling and cleaning again will waste energy and the time.
The objective of the invention is to dyeing machine directly be cooled off and cleaning merging method, thereby overcome the defective that exists in the prior art by a kind of.
Be description of drawings below, in conjunction with the accompanying drawings, can clearly understand method of the present invention.
Accompanying drawing 2 is schematic diagrames of circuit in the direct cooling and cleaning method for dyeing machine of the present invention (2) (4);
Accompanying drawing 3 is schematic diagrames of circuit in the direct cooling and cleaning method for dyeing machine of the present invention (2) (5);
Below in conjunction with accompanying drawing the present invention is carried out detailed narration.
During normal dyeing, the endless form of dye liquor such as the route among Fig. 1 (1) carry out, That is, dye liquor is discharged from the bottom drain 16 of overflow dyeing machine 9, enters pump along circuit (1) 13, by pump 13 input filters 14, enter then heat exchanger 11, hand over by heat The dye liquor that changes continues to enter along circuit 1 head 8 of overflow dyeing machine 9; When needing cooling, cold But water carries out heat and hands over from water inlet 17 by water pump 12 or directly enter heat exchanger 11 (2) in water after changing such as the accompanying drawing 1, (3) route carry out, and what the port of export 18 flowed out is Callable warm water.
When needing heating, by feeding steam in vapor interface 19 heat exchanger 11, waste heat can be from waste heat recovery mouth 20 recovery waste heats.
Yet in the cooling procedure after dyeing is finished, just need not carry out in mode so, adopt method of the present invention this moment, just can reach the time that shortens cooling and cleaning process, and the energy using water wisely, cut down the consumption of energy.
Method of the present invention is that the endless form of dye liquor such as (1) route in the accompanying drawing 1 are carried out, and (2) in the cold water of heat exchanger 11 such as the accompanying drawing 2, (4) route are advanced; Or cooling water is carried out along (2) in the accompanying drawing 3, (5) route, and as the hydraulic pressure deficiency, then must add a water pump 12, to increase hydraulic pressure, as shown in Fig. 1,2,3, in addition, visible forcing press 15 from accompanying drawing.
When the dye liquor in the dyeing machine 9 arrives the setting liquid level, this setting liquid level has fluid level controller 10 controls, then by the floss hole in the accompanying drawing (6) or (7) discharging dye liquor, when liquid level is hanged down in the arrival of the dye liquor in the dyeing machine 9 setting, then stop discharging, replenish cooling water in dye liquor, the circulation that so goes round and begins again arrives till the chilling temperature that sets always.
Because clean cold water is complemented among the dyeing machine 9 by the circuit in the accompanying drawing 2 (2) (4) or by the circuit in the accompanying drawing 3 (2) (5) always, when so the cooling action is finished, the action of cleaning is also and then finished, later cleaning action no longer needs at all, even need to clean, also the cleaning of manying that just comes briefly than original cleaning process.
Thus, cleaning process has been omitted (because cooling and cleaning process have combined), reaches the purpose of shortening processing procedure time, using water wisely, conserver power source naturally.
What deserves to be mentioned is that in cooling and cleaning merging process, most dye liquor impurity has also emitted together, because therefore dye liquor impurity partly, utilize method of the present invention can improve dyeing quality discharging in the cooling indirectly.
Be illustrated more clearly in letter in concrete technology contents of the present invention and the technology for making, below be illustrated again at significant advantage more of the present invention.
1, cooling of the present invention and cleaning merging method do not influence dye bath ratio, see accompanying drawing 1, in dyeing course, (1) route among the endless form of dye liquor such as the figure circulates, (2) among the cold water of heat exchanger 11 such as the figure, (3) route carry out, and therefore can not impact bath raio.
2, cooling of the present invention and cleaning merging method can contract the time of whole dyeing course, in the existing dyeing course, cooling has accounted for the most time, as adopt direct cooling and cleaning method for dyeing machine of the present invention, just can with the cooling with cleaning process entirely also, naturally shortened the time of process.
For example, when dying PET, reduce to 60 ℃ by 130 ℃ during cooling, rate of temperature fall is 2 ℃/min, then needs 35 minutes consuming time; During washing, washing twice, about 40 minutes consuming time, cooling and washing about 75 minutes consuming time altogether, if adopt method of the present invention, then cooling and washing 35 minutes consuming time altogether economized 40 minutes fully.
3, method of the present invention also can be saved cooling water, this is because adopt method of the present invention, to cool off with cleaning process and merge, just cleaning section water is in the past brought the cooling procedure use, therefore no longer need unnecessary cooling water, also be about to traditional cooling section water and saved fully.
4, the above-mentioned method of the present invention can improve dyeing quality, this be because cool but with cleaning process in, most dye liquor impurity has also emitted together, because what dye liquor impurity partly adhered to again when low temperature can't be discharged on the dyeing and weaving thing, if utilize indirect cooling method of the prior art, can't discharge these impurity at all, therefore utilize method of the present invention, in cooling and cleaning process, just emitted most dye liquor impurity, so can improve dyeing quality, reduce the specking flaw that causes because of dye liquor impurity.
But 5, method conserver power source of the present invention, shown in above-mentioned example, when dying PET, cooling and washing about 75 minutes consuming time altogether, if adopt method of the present invention, then cooling and washing 35 minutes consuming time altogether economized 45 minutes fully, that is to say the main pump running supply of electric power that has economized 45 minutes.
Dyeing machine of the present invention directly cooling has following advantage with the method for cleaning merging:
1, dyeing course does not influence bath raio;
2, shorten the time of dyeing course;
3, reduce the water consumption of cooling;
4, reduce energy consumption;
5, improve dyeing quality;
In sum, technology contents of the present invention and technological thought do not appear in the newspapers in the prior art, and method of the present invention is all having outstanding feature aspect the time that shortens dyeing course, using water wisely, energy savings and the raising dyeing quality, and in the production of reality, there is utilization to be worth, for this reason, earnestly ask early this case is authorized.
