Description
Technical field
The present invention relates to the system and devices that the colloid in a kind of pair of crudefiber crop carries out steam explosion removing, belong to clean manufacturing neck
Domain.
Background technique
In various flaxen fiber compositions in addition to cellulose, there are also pectin, hemicellulose, lignin, phat fat and hydrotropes etc.
The attendants of non-cellulose, are referred to as colloid.Degumming is removing fiber peripheral all or part colloid, makes fiber separation, pine
It dissipates, produces fiber-spinnable, to be suitble to spinning requirement.Current retting method has chemical Degumming, biological degumming and biological-chemical
Three kinds of combination degumming.Chemical degumming technique comparative maturity is the method being most widely used at present.But this is but also fiber crops are de-
Glue industry becomes typical highly energy-consuming, high pollution industry.Biological degumming is compared with chemical Degumming, though there is energy saving, at low cost, ring
The advantages that border pollution is few, but since the biological respinse period is long, degumming degree consistent degree is poor, it is difficult to put into large-scale industrial production
In.In addition, the plant fiber as grade textiles, also in fiber chemical residues and smell it is very quick
Sense is realized clear this requires finding a kind of addition of chemicals zero, can also ensure that product quality coherence request in industrial production
Clean, efficient jute fiber degumming technique.
Summary of the invention
The purpose of the invention is to overcome the deficiency of the above-mentioned prior art, a set of new jute fiber degumming processing work is provided
Skill and device mainly include steam explosion degumming, rinsing, dehydration is air-dried, rinses four operation stages of water reuse (treatment.Firstly, de- in steam explosion
Saturated vapor is used only in the adhesive process stage, by instantaneous ejection type steam blasting (ICSE) process, realizes the fruit in flaxen fiber
The attendants structure of the non-cellulose such as glue, hemicellulose, lignin, phat fat and the hydrotrope is destroyed and macromolecular shearing, makes
Gum components are changed into solvable state；Then the whole material after steam explosion is put into rinsing device, by the washing of water into
The separation of row colloid, is dissolved into most of gum components in rinse water；The flaxen fiber after rinsing dehydration is carried out again to air-dry；Rinsing
Water then enters in anaerobic fermentation system the degradation for carrying out dissolved organic matter, and liquid is after solid content filters after the degradation of discharge
It is recirculated back in rinsing device after regeneration with newly added clear water, realizes wastewater reuse.Firstly, the system is handled by ICSE
So that the colloid Transient transformation in flaxen fiber is become small soluble molecules state, realizes the colloid dissolution under chemicals zero adds.Its
It is secondary, on the basis of no chemicals adds, the multiplexing of rinse water is realized by closing anaerobic fermentation, has reached total system cleaning
Production requirement opens new mode for large-scale retting industrial production.
The purpose of the present invention is what is be accomplished by the following way:
The present invention includes: instantaneous ejection type original position steam explosion host groups, potcher, dehydration air-dry machine, anaerobic fermentation tank, mud granule
Filter press, rinsing water reuse (treatment temporary storage tank etc..Wherein, rinsing water reuse (treatment temporary storage tank is connected via pipeline with potcher water supply line.
Its course of work is such that
Raw ramie is first fed in steam explosion host process storehouse.Then pass to the saturated vapor and 1~10min of pressure maintaining of 1~2MPa
Afterwards, in moment blasting process molecular breakdown is occurred for the interfibrous colloid of raw ramie in steam explosion host, is changed into solvable state；Vapour
Flaxen fiber after quick-fried is put to progress water rinsing in potcher；Then the flaxen fiber through clean degumming is fed to dehydration and air-dries
Dehydration is carried out in machine to air-dry；Degumming waste water in potcher containing colloid, which is admitted in anaerobic fermentation tank, carries out biodegrade, then
It is filtered via mud granule filter press, is expelled in rinsing water reuse (treatment temporary storage tank and stands；Recycled water and the new water in part after standing
Again it sends back to and carries out washing degumming in potcher, to complete whole steam explosion retting production processes.
The invention has the advantages that
1, the instantaneous ejection type steam explosion process in the present invention passes through the high speed of hydrone only with single water vapour as medium
Explosion kinetic energy makes the fructose pectin between flaxen fiber soften and dissolve, and gets rid of the dependence to chemicals, realizes in flaxen fiber
Gum components are changed into solvable state.
2, the jute fiber degumming rinse water in the present invention can utmostly realize water by biodegrade and sludge filtration
Multiplexing, avoid the discharge of system high concentration COD waste water.
3, since the shock wave that explosion generates can produce fracture and recombinate effect in molecular level, so that being deposited in flaxen fiber
Germ, worm's ovum by complete inactivation and be crushed, the biotoxins macromolecular such as aflatoxin is sheared and loses bio-toxicity,
Further increase biological safety of the flaxen fiber for textile clothing.
4, chemical agent is not used in system whole process of the invention, avoids original chemical method to the drop of flaxen fiber structure
Solution effect, improves the mechanical strength and toughness of flaxen fiber, also further improves the yield of jute fiber degumming process.
5, the bio-natural gas generated in operational process of the invention reduces system capacity consumption, realizes flaxen fiber
The environmental-friendly and energy regenerating of degumming tech.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the system flow schematic diagram of one embodiment of the invention.
Referring to attached drawing, the present invention includes: instantaneous ejection type original position steam explosion host groups 1, potcher 2, dehydration air-dry machine 3, detests
Aerobe fermentation tank 4, mud granule filter press 5, rinsing water reuse (treatment temporary storage tank 6 etc..
In Fig. 1 embodiment: rinsing water reuse (treatment temporary storage tank is connected via pipeline with potcher water supply line.Its course of work
It is such that raw ramie is first fed in steam explosion host process storehouse.Then pass to 1~2MPa saturated vapor and pressure maintaining 1~
After 10min, in moment blasting process molecular breakdown is occurred for the interfibrous colloid of raw ramie in steam explosion host, is changed into solvable shape
State；Flaxen fiber after steam explosion is put to progress water rinsing in potcher；Then the flaxen fiber through clean degumming is fed to de-
Dehydration is carried out in water air-dry machine to air-dry；It is given birth in the anaerobic fermentation tank that degumming waste water in potcher containing colloid is then admitted to
Object degradation, then filtered via mud granule filter press, it is expelled in rinsing water reuse (treatment temporary storage tank and stands；Recycled water after standing with
The new water in part is sent back to again carries out washing degumming in potcher, to complete whole steam explosion retting production processes.
