Abstract
The invention discloses a method for recycling waste alkali liquor, in particular to a method for recycling the waste alkali liquor generated in the process of mercerized finish of fabrics. Dyeing and finishing industry is a key link of fabric dyeing and finishing in textile industry, wherein the mercerized finish of the fabrics mainly uses a great amount of high concentration stock solution of caustic soda, the traditional process is lack of a system for recycling the waste alkali liquor generated in the mercerized process, and the waste alkali liquor is directly discharged into a sewage treatment system through a sewer to be treated, thereby resource waste and a great amount of waste water are generated, and extremely heavy burden is brought to the sewage treatment system. The invention provides the method for recycling the waste alkali liquor in the technological process of mercerized finish of fabrics, thus the waste alkali liquor can be thoroughly precipitated, cleaned and turned into recycled alkali liquor by additionally arranging a double-groove precipitation system, and the recycled alkali liquor is circularly utilized in the mercerized technological process. The method can be also applied to the production of dyeing machines, dye vats, cheese dyeing machines and oxygen bleaching machines.
Description
Technical field
The present invention relates to the method that a kind of waste lye is recycled, the method that the waste lye that produces in particularly a kind of lining gloss finish process is recycled.
Background technology
Dyeing and finishing industry is a key link of dyeing fabric and arrangement in the weaving industry, and gloss finish technological process wherein is an important procedure that lining is carried out the texture arrangement.Lining carries out gloss finish and mainly is to use a large amount of high density caustic soda alkali lye, and fabric fibre is carried out chemical action, makes it produce sheen effect.In traditional technology, the waste lye that produces in the mercerization process, because lack recovery system, directly entering Sewage treatment systems by water drain handles, not only cause the wasting of resources but also cause a large amount of waste water, cause very big burden to Sewage treatment systems, also have some producers even directly enter rivers and cause bigger pollution and waste, more do not meet the policies and regulations of national environmental protection and energy-saving and emission-reduction.
Summary of the invention
The present invention has overcome existing traditional gloss finish technological process waste lye has been lacked recovery system, causes the defective of the wasting of resources, a large amount of waste water of generation and wastewater treatment burden.The method that a kind of lining gloss finish technological process waste lye is recycled has been proposed.Technical solutions according to the invention are: adopt Fig. 2 double flute settling system, waste lye is at first entered precipitation cleaning slot 4 by input tube 1 precipitate cleaning, will precipitate alkali lye suction header tank 5 deposits after cleaning then.Reclaim alkali lye 6 and can be switched to water supply pipe 2 among Fig. 1 by output channel 7, be incorporated into reuse in the mercerising groove 3, the electronic probe that mercerising groove 3 is joined the alkali system by mercerizing tange comes automatic configuration effort alkali lye, recovery alkali lye can be utilized by normal circulation, reached the purpose that economizes on resources, reduces discharging, alleviates the sewage disposal burden.Reclaiming alkali lye 6 not only can also be used in dyeing machinery, dye vat, cheese dyeing, the oxygen bleaching machine production by output channel in the gloss finish system applies.This cover system calculates by the ordinary production time through the application implementation of applicant company, can save 1,300,000 yuan of costs every year, reduces 100,000 tons of quantity of wastewater effluent, economizes on resources and reduces and obtained useful effect aspect the discharging in enterprise.
Description of drawings
Fig. 1 is a gloss finish technological process synoptic diagram.
Gloss finish technological process: straight rolling alkali------------straight roller lixiviating is dried wherein pin tentering, running water pipe 2 mercerising grooves 3 by water tank lixiviating----
Fig. 2 is a double flute settling system synoptic diagram.
Wherein, waste lye input tube 1 precipitation cleaning slot 4 header tanks 5 reclaim alkali lye 6 and reclaim alkali lye output channel 7
Embodiment
Concrete actual illustration below in conjunction with accompanying drawing and applicant company is described further technical scheme of the present invention.Illustration one, the double flute settling system parameter of applicant company design is as follows:
60 tons of precipitation cleaning slot steel tank volumes.
15 tons of header tank steel tank volumes.
The starting material that gloss finish is used: high alkali liquid original liquid concentration 400g/L
The desired work concentration of lye of gloss finish technology 200g/L
The waste lye concentration 40g/L that discharges under the traditional technology
Reclaim the concentration 40g/L of alkali lye reuse
Effect on mercerizing tange:
The sewage disposal emission reduction effect:
Claims (2)
1. the method recycled of a waste lye, the method that the waste lye that produces in particularly a kind of lining gloss finish process is recycled.It is characterized in that increasing a double flute settling system, waste lye is at first precipitated by precipitation cleaning slot (4), will precipitate recovery alkali lye (6) suction header tank (5) deposit after cleaning then.
2. the method that waste lye according to claim 1 is recycled, it is characterized in that reclaiming alkali lye (6) can be directly by the reuse of gloss finish operation, can also reuse in dyeing machinery, dye vat, cheese dyeing, oxygen bleaching machine production.
