Detailed description of the invention
As shown in Figure 1, the present invention is a kind of can, by the garment dyeing equipment of residual liquid recycling, comprise dye vat 1 and rustless steel container, and rustless steel container is provided with one or several altogether, and rustless steel container is communicated with dye vat 1 by the pipeline with water pump.
Rustless steel container is set quantity according to the needs of dyeing and the residual pin water of actual reuse, and general 3-5 is individual just passable.In the present embodiment, rustless steel container is provided with 5 altogether, is respectively: rustless steel container 2a, rustless steel container 2b, rustless steel container 2c, rustless steel container 2d, rustless steel container 2e.Rustless steel container 2a is communicated with dye vat 1 by the pipeline with water pump 3a, rustless steel container 2b is communicated with dye vat 1 by the pipeline with water pump 3b, rustless steel container 2c is communicated with dye vat 1 by the pipeline with water pump 3c, rustless steel container 2d is communicated with dye vat 1 by the pipeline with water pump 3d, and rustless steel container 2e is communicated with dye vat 1 by the pipeline with water pump 3e.
The present invention is a kind of can, by the using method of the garment dyeing equipment of residual liquid recycling, be comprised the following steps:
First clothing to be dyed is placed in to dye vat 1 and carries out the first cylinder dyeing and process, by a certain procedure in dyeing processing procedure or twice and the above operation of twice pin water after treatment are delivered in corresponding rustless steel container and are collected by water pump arbitrarily;
First is after dying garment dyeing and finishing dealing with, from the interior taking-up of dye vat 1;
Clothing to be dyed second batch is placed in to dye vat 1 and carries out the second cylinder dyeing processing, in dyeing processing procedure, when a certain procedure is to should have the pin water being collected in rustless steel container time, just by water pump, the pin water corresponding with this procedure is delivered to and in dye vat 1, carries out reuse; After reuse, more corresponding pin water is transmitted back in corresponding rustless steel container and is collected by water pump;
Second batch is after dying garment dyeing and finishing dealing with, from the interior taking-up of dye vat 1;
The 3rd batch of clothing to be dyed is placed in to dye vat 1 and carries out the 3rd cylinder dyeing and process, dyeing processing procedure is the same with second batch, with this circulating and recovering pin water successively.
When pin water carries out reuse, the additional amount of water is 10-20%, and the additional amount of auxiliary agent is 10-20%, and in dyeing process, the additional amount of dyestuff is 70-90%.When concrete enforcement, first test to determine by sample with pin water and will add how many dyestuffs and auxiliary agent.
The reuse method of above-mentioned this pin water always reuse goes down, but in order to ensure color fastness, light colour reuse 4-5 time, dark colour reuse 2-3 time.
Illustrate using method of the present invention below in conjunction with Fig. 1:
Dyeing flow process is generally: pre-treatment---dyeing---washing---fixation---softness and function treatment, pin water after pre-treatment finishes is transported in rustless steel container 2a by water pump 3a, the product that dye vat is 1 li then does dyeing process, dyeing finishes rear the pin water after dyeing and is transported in rustless steel container 2b by water pump 3b, product in dye vat 1 then carries out washing step, washing finishes rear the pin water after washing and is transported in rustless steel container 2c by water pump 3c, product in dye vat 1 then carries out fixation treatment operation, fixation treatment finishes rear residual pin water after fixation to be transported in rustless steel container 2d by water pump 3d, product in dye vat 1 then carries out softness and function treatment operation, softness and function treatment finish rear the residual pin water of processing and are transported in rustless steel container 2e by water pump 3e.At this moment a cylinder product dyeing finishes, product is taken out from dye vat 1, again an other cylinder is dyed to same color identical product and put into dye vat 1 and do the second cylinder dyeing, more respectively the pin water pump in rustless steel container 2a, rustless steel container 2b, rustless steel container 2c, rustless steel container 2d, rustless steel container 2e is returned and in dye vat 1, carries out pre-treatment---dyeing---washing---fixation---softness and function treatment.
As long as add the water of 10%-20% and the auxiliary agent of 10%-20% when the each operation of the second cylinder is processed, dyeing process is added the dyestuff of 70%-90%, tests to determine will add how many dyestuffs and auxiliary agent while specifically enforcement with residual pin water by sample.
The first cylinder each operation residual pin water after treatment that dyes can all be collected in rustless steel container, and reuse in the time of next cylinder dyeing, has accomplished zero-emission.
The present invention compared with prior art, has following outstanding advantages and good effect:
1, garment dyeing equipment of the present invention is compared with conventional garment dyeing equipment, and the increase of device fabrication cost needs only 10%, within two months, just can return and increase cost.
2, water saving, joint vapour, reduction of discharging, taking reuse three times as example, dye the product of 100KG, suppose that bath raio is 1:10, so every cylinder water is 1000KG, five processes is 5000KG water altogether, increase for the second time 10%, increase for the third time water 10% again, dying three cylinder total waters is 6000KG, it is 15000KG that routine is dyed three cylinder waters, the 9000KG that so just can economize on water reduces blowdown 9000KG, because residual pin water is to have uniform temperature simultaneously, so it is just passable as long as supplement part steam that second, third cylinder dyeing adds man-hour, can save steam 50%.Also reduce the consumption of dyestuff and auxiliary agent, reduced the about 10%-20% of dye dosage, reduced auxiliary dosage 60%.
Above-described embodiment is only for the inventive concept of the present invention of explaining, but not restriction to rights protection of the present invention, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should fall into protection scope of the present invention.
