Description
Technical field
The utility model relates to a kind of processing units of waste liquid, especially, are related to a kind of processing unit of viscose glue waste liquid, belong to
Waste recovery and environmental protection treatment technical field in viscose rayon production.
Background technique
Viscose rayon is using high molecular material wood pulp, cotton pulp containing native cellulose etc. by chemistry and mechanical means
The chemical fibre being process is kind closest with natural fiber clothes performance in chemical fibre, has soft, suction
It is penetrable ventilated, overhang elegant, bright, antistatic the features such as being relatively easy to textile process, be derived from day however better than it is natural again
Raw cellulose fibre, is one of the important materials of textile industry raw material.There is viscose rayon enterprise about 40 in China at present, except production
Outside common viscose fiber (long filament, staple fiber) and high-tenacity fibre, the viscose rayon of high wet modulus fiber and special property also has life
It produces.
A large amount of industrial chemicals is needed in production process of viscose fiber, can generate a large amount of waste water, these waste water contain sulphur
Acid, zinc sulfate, carbon disulfide, cellulose, dissolved organic matter etc. generate very big harm to environment, are textile industries
One of primary pollution source.
Wherein, in viscose rayon forming process, viscose glue and acid coagulating bath are acted on, and are neutralized alkali, cellulose sulfonic acid
Sodium is decomposed and regenerates cellulose hydrate, cellulose sulfonate, free NaOH during this in viscose glue and because of side reaction
The Na of generation2CS3, the side reaction products such as polysulfide can generate sodium sulphate with the sulfuric acid reaction in coagulating bath.Viscose rayon
Include the acid bath process of consumption sulfuric acid in production, further includes the sheet steeping process for consuming sodium hydroxide, alkali cellulose sulphonic acid ester
Dissolution process, concise compresses and washes process and sour water neutralisation treatment operation at waste gas absorption process.
The main function of sodium sulphate is that viscose glue liquid stream is promoted to solidify and inhibit sulfuric acid dissociation in coagulating bath, makes cellulose sulfonic acid
The reproduction speed of ester delays, and improves the concentration of sodium sulphate in coagulating bath, and spinning operation is easier to, and tow is not easy to break end, and can drop
The degree of dissociation of low-sulfur acid, makes tow still have certain residual ester value when leaving coagulating bath, but the sodium sulphate in coagulating bath
Also unsuitable excessively high, otherwise fibre solidification can be made to overrun, fine structure cannot be formed, and coarse crystalline particle is generated, fiber
Ectonexine is also inhomogenous.
During the spinning process, the sodium sulphate content in coagulating bath is continuously increased so that its requirement for being unable to satisfy technique, such as
Fruit only passes through the raw material being consumed in addition coagulating bath will make the total amount of coagulating bath increase to supplement its concentration recycling
Add and can not store, can only at regular time and quantity discharge coagulating bath, acid therein, salt, metal ion etc. will cause serious ring
Border pollution brings huge pressure to sewage treatment and causes the huge waste of resource.And by sodium sulphate extra in acid bath
High temperature crystallization is carried out, sodium sulfate crystal is isolated, so that the content of the sodium sulphate in acid bath is met technique requirement, without arranging daily
Fall acid to balance acid bath, by directly continuing to use for spinning workshop after charging, acid discharge can be reduced, output anhydrous sodium sulphate reduces ring
Packing pressure, but due to sodium sulphate high temperature crystallization is produced in coagulating bath anhydrous sodium sulphate it is impure it is more, added value itself is low makes
Economic benefit can not be generated by obtaining it, and a large amount of solid salt can not be handled, and still bring certain pressure to environmental protection.

Water can recycle, good purification, high-efficient, reduce water resource waste, energy conservation and environmental protection.But the technical solution stresses pair
Viscose Waste Water carries out environmental protection treatment, and not specific, circulation and being recycled to Viscose Waste Water efficiently etc..
For the prior art, there is problems: existing viscose glue liquid waste treating apparatus can not be expanded to industry
Metaplasia produces, and is only limitted to the experimental stage；After viscose glue waste liquid is handled, there is also wastes discharge, is unfavorable for environmentally friendly production；To viscous
After glue waste liquid carries out sulfuric acid, sodium hydroxide, the recycling of dilute sulfuric acid sodium, purity and concentration are not able to satisfy actual demand, i.e. impurity is more, dense
Spend small, being back to after cellulose viscose manufacturing technique influences greatly product quality, therefore could be used to produce after need to being further processed
