I.e. recoverable.
This utility model is further described below with specific embodiment.
Embodiment
Fig. 2 is referred to, the present embodiment provides a kind of Direct fast light black G clean-production system, using the technique stream of the system
Journey is described as follows：
Process for cleanly preparing in the present embodiment is primarily directed in former traditional handicraft sour (salt) analysis-filtration-alkali soluble ring
The replacement of section, therefore the technique unit before and after the link is consistent with former traditional handicraft.
Due to there is more suspended particulate substance or colloidal substance in the reacted solution of sodium sulfide reducing, therefore in this enforcement
In the production technology of example, solution before ion electrotransport delivery systems are entered through filter pressing or centrifugation mode remove impurity, and pass through
Crossing cartridge filter carries out secondary filter.Additionally, also through heat-exchange system so that control solution temperature is in certain scope.
Ion electrotransport delivery systems are in the presence of DC electric field, using the selective penetrated property of ion-conductance transport membrane, realize
In solution, inorganic salt is separated with dyestuff intermediate, obtains strong brine and the dyestuff intermediate solution after purification.This process acid adding
To adjust pH value.This process separation efficiency is high, and only very small amount valuable material (dyestuff intermediate, raw material) can be arranged with strong brine
Enter Waste Water Treatment.Therefore, the strong brine content of organics that ion electrotransport delivery systems are produced is low, and COD can be by former technique waste water
30000mg/L be down to below 1500mg/L, intractability is substantially reduced.
Additionally, the key of ion electrotransport delivery systems is the selection of ion-conductance transport membrane.This utility model is for process object
The characteristics of middle institute's saliferous is mainly sodium thiosulfate, through test of many times, final choice alloy film substitutes conventional use of homogeneous
Film or half homogeneous membrane.The alloy film membrane resistance is extremely low, with suitable pore structure and specific ion selective penetrated property, the alloy
The migration velocity for being disposed to balance anions and canons of the specific ion selective penetrated property of film, it is to avoid due to ion migration speed
Degree difference causes greatly local to be acidified or alkalize, and affects desalting efficiency.Replaced after homogeneous membrane or half homogeneous membrane using alloy film, electricity
Power cost declines, and desalination speed is greatly improved, and the desalination operation deadline can foreshorten to 6h by 13.5h, when efficiently solving long
Between yield present in desalination processes the problems such as decline (declining about 5%～8%), desalting chamber local and be acidified, meanwhile, ion-conductance is moved
Move system scale and can reduce 50%, significantly save and take up an area.
As in the solution that obtains after the electrodialysis desalination of ion electrotransport delivery systems, dyestuff intermediate concentration is low (about
For 10%), water content is big, if being directly used in subsequent production link, not only equipment scale need to be significantly increased, a large amount of consumption are also needed
The energy consumption of the raw material and spray drying process of the subsequent techniques such as acid, alkali, salt, too big reaction solution volume is for control reaction temperature
Degree is also very unfavorable.In order to solve these problems, the present embodiment is right using two-stage ductwork type reverse osmosis membrane filtration system (STRO)
Concentrated through the dyestuff intermediate solution after ion electrotransport delivery systems desalination purification, solution recovery up to 50%, ie in solution
Volume can be reduced to original 1/2, and the concentration of dyestuff intermediate is doubled.This means that the scale of production equipment can reduce
When concentrating without STRO 1/2, the energy consumption (key component of follow-up link production cost) of spray drying process also may be used
Reduce by 50% or so.Additionally, for the reconstruction project in actual production, the production equipment of forward and backward process section is fixed, if with
New technology substitutes acid out-filtration-alkali soluble technique, then certainly will require that new technology and forward and backward process section carry out seamless connection, and only
By electrodialysis desalination system be unable to reach requirement (pickling-filtration-alkali soluble technique obtain be intermediate saturated solution, and
Amount of solution that electrodialysis desalination system is obtained is big and concentration is low), it is necessary to further improve target substance concentration could meet existing
The reaction condition that equipment has been set.Therefore, the present embodiment is concentrated using two-stage STRO system, not only significantly can be reduced follow-up
The construction scale of system, is greatly reduced the energy consumption of spray drying process, also can reach the mesh with existing production system seamless connection
's.Additionally, the product water of STRO systems can also reuse to ion electrotransport delivery systems, can so reduce the consumption of tap water, reduce into
This.
Ion electrotransport delivery systems discharge strong brine because containing only a small amount of Organic substance (waste water that COD is produced by former technique
30000mg/L is down to below 1500mg/L), intractability is substantially reduced, by " catalysis reduction-aerating oxidation-precipitation-catalysis
Materialization means as ozone oxidation " are processed and can reach emission request, and and STRO systems containing few pollutant reverse osmosiss
Produce water together with enterprise's sewage plant water outlet dual disposal.Wherein, catalytic reduction unit is in the presence of catalyst, using activity
The dissolubility macromolecular substances remained in strong brine are converted into insoluble matters by filler, and in follow-up aerating oxidation unit by throwing
Plus flocculant is allowed to precipitation and removes, and not only can significantly cut down COD, there is good decolorization also during this, while also
Sodium thiosulfate in removable waste water.Aerating oxidation unit employs patent aeration process, blocks up with efficient, energy-conservation, anti-soil
Technical advantage, its purpose of design be by aeration (while adding flocculant, decolorising agent, catalyst) enhanced coagulation, decolourize effect
Really, the sodium thiosulfate of residual is further removed, to ensure that follow-up ozone is mainly used in oxidation dissolution hardly degraded organic substance,
So as to reduce ozone usage, reduce processing cost.Precipitation unit is used for separating insoluble matter, and its water outlet enters single-stage or two-stage is urged
Change ozone oxidation unit, the second level ozone unit of wherein two-stage O3 catalytic oxidation unit is only used as support facility, i.e., first
If level ozone unit water outlet reaches requirement, then second level ozone unit does not start.
For whole process for cleanly preparing, due to having reclaimed the valuable material of original loss so that the product of final products
Amount improves 15%～20%, and the wastewater treatment difficulty for producing declines to a great extent, therefore whole economic efficiency is significantly, and cost of investment exists
I.e. recoverable in a short time.
The present embodiment substitutes acid (salt) analysis-filtering technique of former technique using ion electromigration techniques, with four big technology
Advantage：Consumption sour (salt) is measured less, desalting efficiency is high, little, valuable material turnover rate is low to produce wastewater treatment difficulty；
The present embodiment realizes the concentration of desalination midbody solution using two-stage STRO system, not only can significantly reduce follow-up life
The construction scale of product system, is greatly reduced the energy consumption of spray drying process, also can reach the purpose with existed system seamless connection；
