Matter；The impurity such as wax, grease, pectin also become soluble washable substance, cottonseed by the emulsification and saponification of Tea Saponin
Shell pigment is oxidized fracture by the blanching effect of hydrogen peroxide, chromophoric group, and pigment is removed.Third step), first to the 7th
Washed in lattice rinsing bowl, before the first to the 6th lattice rinsing bowl be enclosed water washing trough, 90 ° of washing temperature, constant temperature is automatic
Control；Last 7th lattice rinsing bowl is open rinsing bowl, 50 ° -60 ° of water temperature.The water of 7th lattice rinsing bowl successively forward adverse current
To the first lattice rinsing bowl, fresh clean water is added by the 7th lattice rinsing bowl, and treated for the addition of first via reuse water lines 21
Recycle-water enters the 4th lattice rinsing bowl 7, and waste water is flowed out from the first lattice rinsing bowl, subsequently into integrated waste water circulation treating device
It is handled.4th step), the cloth for washing completion is dried on three column drying cylinder dryers 11, using steam as medium, indirectly
Cloth is dried.Baking step evaporates 20% moisture, supplements fresh clean water in last 7th lattice rinsing bowl.Cloth after drying
Clot is expected, in case rear process uses.
In box integrated waste water circulation treating device of the invention, rotary drum filters 13 mainly continuously filter out waste water
In the fiber soft flocks that falls off；Wastewater heat exchange device 14 plays the role of reducing waste water temperature, keeps the substances such as the PVA slurry in waste water fast
Speed aggregates into floc sedimentation, and then floats to liquid level at colloid group.Wastewater heat exchange device 14 also acts as simultaneously is mended using waste water energy heats
Fill the effect with water.Coagulant medicament and macromolecule flocculant is added in subsequent air bearing process, the PVA slurry in waste liquid can be made
Rapid flocculation is at floccule.Air floatation machine 15 is stingy by air bearing generation 15-20um for that will contain the waste water of a large amount of floccules
It steeps, the floccule in waste water, due to floccule light specific gravity, floats to after liquid level together with echoing with bubble and is sent into waste residue by scraper plate
The slurry of collecting vessel 32, this 80% or more process is removed.The clear liquid that air floatation machine comes out enters settling tank 16, part floc sedimentation and fibre
Dimension absorption is combined together, and specific gravity is larger, can sink to bottom, while some scale slags can also sink to device bottom, these pass through
Precipitating is excluded from 16 bottom of settling tank, enters waste residue collecting vessel 32 together.The floccule and precipitating that air floatation machine and sedimentation basin generate
Object is filtered by bag filter 17, is then dried or is dried, and it is general solid that main component, which is cotton wool, starch, scale slag etc.,
It is useless, transfer to refuse-burning plant to burn the utilization of resources again.Water tank 18 covers, and is not infected with raw cold water, treated in this way recycle-water
It can never degenerate for a long time.
Sewage zero-discharge lining cloth preprocessing system provided by the invention is in terms of the equipment scale that yield is 3000 ms/h
It calculates, water consumption is 5.5 tons/h per hour, wherein material 0.5 ton/h of water, 5 tons/h of water scouring water, supplements 1.5 tons of fresh water amount
H, 4 tons/h of water re-using, 1.5 tons/h of drying evaporation.Last 3 lattice in the 7 lattice washing of equipment supplement fresh clean water, to guarantee
The abundance of water, while guaranteeing the water washing effect of end product, cloth cover pH value is neutrality.About 1600 tons of steam can be saved year, year subtracts
Few about 14400 tons of discharge of wastewater.
Product whiteness, feel, the intensity produced using sewage zero-discharge lining cloth preprocessing system provided by the invention is reached
To higher standard, not waste discharge.It realizes lining cloth pre-treatment and moves back to boil and float process hoop structure.
The above is only highly preferred embodiment of the present invention, is not intended to limit the present invention in any form, and is appointed
What those skilled in the art, without departing from the scope of the technical proposal of the invention, using in the method for the disclosure above
Appearance makes many possible changes and modifications to technical solution of the present invention, is all within the protection scope of the claims.
