Description

A kind of clean preparation method of plant-fiber product

Technical field

The present invention proposes a kind of clean preparation method of plant-fiber product, wherein relate to the deinking in production process or degreasing or and the manipulation of regeneration of black liquor that delignification forms and recycling etc., the horizontal stroke of the multi-product production field of platymiscium fiber product Huo Yu composite fertilizer Nutrition Soil, feed etc., the longitudinally coupling of process node or integrated etc. technology category.

Background technology

Plant-fiber product production field and composite fertilizer's Nutrition Soil or and the products production field such as feed between, there is no now horizontal stroke between tight and unobstructed extroversion, the longitudinal process channel of mass transfer coupling; Cotton in plant-fiber product production field is or/and between the sub-products production field of the sub-products production field of fiber crops and yarn thereof, fabric and pulping and paper-making, also there is no in neutron field, products production field to horizontal stroke, the longitudinal process channel of mass transfer coupling; Even between this two large class pulp product of the bleached pulp in the sub-products production field of pulping and paper-making and non-bleaching true qualities paper pulp, also without being of value to horizontal stroke in the sub-products production field of each product Sustainable development, longitudinal mass transfer channel.

Because plant-fiber product production field seriously lacks the multidirectional mass transfer channel between products production field inside and outside, cause still to exist so far vegetable fibre is implemented to degreasing or and the processing such as bleaching and a difficult problem that the waste water of generation is arranged nowhere.In plant-fiber product production field, discharge of wastewater is maximum two classes, and what rank the first is pulping and papermaking industry, and it two is that cotton is or/and the degreasing bleaching industry of fiber crops and yarn thereof, fabric; It is only the wastewater flow rate that the sub-industry of pulping and paper-making in vegetable fibre industry causes, according to the Chinese environmental annual report as far back as 2002: the above papermaking in county and county and paper products industry waste water year discharge 3.53 hundred million m3, just accounted for 18.2% of national total release at that time, in waste discharge, COD287.7 is ten thousand tons, accounts for 40.8% of national total release.And even to this day 2012, the rank that its blowdown is polluted still is located prostatitis!

The main outer row's of pulping and papermaking industry waste water, the first derive to plant materials implement fiber separation degreasing or and the process such as delignification prepare coloured black liquor that new paper pulp produces; It two is to derive from waste paper to be implemented to the processes such as pulping, deinking, bleaching and prepared the waste water that regenerated paper pulp produces, and always contains the heavy metal that comes from ink in this kind of waste water; It three is to derive from manufacturing paper with pulp after paper or the paper pulp dregs of rice containing the paper making additive mixing suspension liquid of the paper pulp of paper pulp 1 ~ 3% left and right and interpolation again, and the outer row of recycle intermediate circulating water repeatedly, in this kind of outer draining, also can contain slurrying and all papermaking is used and interpolation auxiliary agent composition, and repeatedly can be in water after clean water treatment accumulation leave the water-soluble inorganic salt that comes from water purification agent Tai-Ace S 150, the poly-aluminium of alkali formula chlorination, alkali formula polyiron sulfate, potassium alum, sodium alum etc. etc.

The new paper pulp of paper grade (stock) claims again former paper pulp, the raw material that it is used, is still mainly derived from plant materials Mierocrystalline cellulose, at present in plant materials, Mierocrystalline cellulose conventionally and hemicellulose, xylogen also claim lignin, interweave together with symbiosis with the components such as resin that comprise all colloid compositions etc.In plant materials, Mierocrystalline cellulose is mixed mutually because of the components such as resin with hydrophobic nature, and it does not have wetting ability conventionally, and do not have hydrophilic fiber, in the current main wet method copy paper technique of using, is not difficult to into paper.

To from plant materials, isolate suitable paper Mierocrystalline cellulose, and make again it there is wetting ability, modern industry still mainly contains 5 classes in the traditional method of using: 1), use that concentrated base hot conditions processes plant material be called as the slurrying of alkaline process separating at high temperature, this method is specifically according to the difference of selected alkali, can substantially be subdivided into again three kinds of lime method, soda processes and Method of Sodas; 2), use sulphite pyroprocessing plant material be called as the separated slurrying of sulphite process, it is several that this method can be further subdivided into again acid sulfite process, neutrality and alkali sulfite process etc.; 3), organic solvent method; 4), mechanical hot-mill method; 5), biological separation method.Proof by industrialization practice, it is high that these traditional methods itself all exist respectively cost to some extent, the technology barrier that is difficult to overcome of the unstable grade of quality, these main methods do not build in products production field, outer horizontal stroke, longitudinal mass transfer technique hyperchannel, cause its degreasing or and delignification, bleaching, sieve and wash, what in the treating processess such as papermaking, generate is a large amount of containing sodium element and containing high COD, the aterrimus alkali of BOD is or/and the water of salt, or containing high COD, the pitch black color acid of BOD or/and the water of salt discharge nowhere, cause thus technological process used and water, after use, all become the waste water of serious environment pollution.

And the alkali using in Ancient Times in China papermaking is mainly lime, what work is calcium hydroxide, but calcium hydroxide to the plant colloid in plant materials or and the stripping of lignin used very weak, its efficiency is too low.So under modern market condition, merely with its do coming unstuck of white slurry or and the technique of the alkaline assistant main material of delignification be eliminated.

According to Chinese patent recently disclosed content see, in clean paper pulp technical field, recent noticeable new technology progress has: Chinese patent CN200710117658.0(method for the brewed pulping of cold soaking of papermaking), the method is characterized in that: pulping process is not used caustic soda, without massive laundering, avoided the discharge of strong basicity sewage, its slurry yield is compared with the strong alkali method that is rich in sodium element, can improve 20%.But after to the conscientiously reading of its specification sheets, find, with 1 ton of paper pulp of the every production of this method, from its promoting agent used, soak main liquid, soak auxiliary liquid the entrained sodium ion entering in 7.2 ~ 34.2kg scope.If the outer draining containing sodium ion salt concn with general receptible upper safety limit value 1 ‰ concentration of environment vegetation, this kind of paper pulp is being sieved and washed or/and copy paper operation, the sodium ion amount that the paper of being manufactured paper with pulp if disregard is taken away, arranging outward containing natrium brine of its last safety, paper pulp per ton is being sieved and washed or/and copy paper operation still needs 7.2 ~ 34.2 tons of water of water; Wherein do not mention arrange sieving and washing or/and how wastewater from paper machine makes resource utilization recycling containing sodium salt yet.The paper pulp of this kind of pulping method gained in addition, because contained xylogen is wherein far above conventional high-temperature cooking process, and content of lignin is high, can make paper have Nai Hou not and not soft etc. flaw.The paper pulp with similar advantage and flaw is prepared scheme, also just like Chinese patent application CN201010284034.X(grass as raw material without chlorine without sulphur free pulping method), Chinese patent application CN201010150534.4(obtaining non-fibrous matters in dry mode and do not produce the pulping process of water) etc.At present in clean paper pulp technical field, also only rest on not effluent of paper pulp processed itself or and simple pursuit stage of not using sulfur-bearing or chlorine bleaching agent; There is no the scheme of not draining of paper pulp operation processed further perfect again, and to the horizontal stroke inside and outside products production field, extending longitudinally, as considered how can be connected with lower procedure, make downstream sieve and wash or/and the recirculated water of copy paper operation is discharged still less or and easily resource utilization effectively recycle, realize the cleaning of whole products production field of slurrying and papermaking and produce and technical scheme that resource utilization rationally recycles etc.

From known Chinese patent literature, process the preferably mill by coacervation and precipitation of alkali and xylogen in CN85106333(black liquid seemingly of black liquor processed) and CN90104181.5(process the mill by coacervation and precipitation of black liquid), CN85106333 has mentioned in literary composition in application: " using CaO or Ca (OH) 2 as coagulation agent; be added in the solution of black liquor or humic acids, just can make the salt coagulation of xylogen or humic acids.After filtration, gained filtrate is alkaline solution, and gained precipitation can be purified as the salt of xylogen or humic acids.", but CN85106333 does not provide specific embodiment in application literary composition, therefore CN85106333 is one, inadequate patent application document is disclosed, CN85106333 does not mention whether this method can be applied to not contain the deinking of xylogen or humic acids yet, mechanical-chemical method paper pulp, cotton is or/and fiber crops or its yarn and the formed black liquor of fabric degreasing thereof, from CN85106333 can not derive adapted this method slurrying or and paper-making process, in the safety range that sodium ions content in the water that its process is discharged can bear in vegetation, last this application is not authorized, and CN90104181.5 has mentioned in application literary composition: " the method is in the Normal juice black liquid of being extruded by pulp-extruding machine, add 2 ~ 5%(grams per milliliter) solid greening calcium or waste solution of calcium chloride, make xylogen coagulation, then by filter, filter, obtain solid shape xylogen and sig water, xylogen can be used as fuel utilization, sig water can recycle or reclaim alkali in blowback spherical digester ".Though CN90104181.5 is that disclose can be from being newly settled out xylogen paper fiber black liquor processed, but this application not only has the unit of statement calcium chloride consumption to mark chaotic flaw, this application that main is can not realize the xylogen sodium salt of solubility is changed into sodium hydroxide, also make to filter in the sig water of rear gained simultaneously and dissolved into and there is corrosive chlorine root, and this chlorine root can be with constantly rising after reuse increased frequency, this is by the equipment of heavy corrosion paper pulp processed, and this application is not finally authorized yet.

Relevant paper-making effluent is done the exploitation of fertilizer, existing bibliographical information, as: salt of wormwood or potassium hydroxide and hydrogen peroxide manufacture paper pulp and organic potassic fertilizer for CN201010106997.0(), CN00807764.9(prepares cellulose pulp and contains the method for potassic fertilizer).The maximum implementation barrier of this two method is: in paper pulp formula processed, with salt of wormwood or potassium hydroxide, substitute or the alternative sodium carbonate of part or sodium hydroxide, can make the cost of slurrying suddenly increase, because the market price of potash is 10 times of soda.

Also have in addition: CN200710157887.5(manufactures the method for composite granulated fertilizer with the waste of employing straw slurry paper-making), CN99113886.4(utilizes black liquid cured article to produce the technique of organonitrogen phosphorus potassium complex fertilizer) etc.

The vegetable fibre degreasing that the document that above-mentioned relevant paper-making effluent is made fertilizer is introduced, the technical scheme that bleaching technology field waste water is made fertilizer, its feature is: in degreasing, bleaching formula, only with potassio, replace sodium merely, composting material all needs the highly energy-consuming process of heating concentrate.The paper waste of Introduction of Literatures is made the scheme of fertilizer, if be only, with potassio, replace sodium simply, not only can make auxiliary agent materials valency rise more than one times, if will be containing potassium waste water in line farmland nearby, that also will be the same with sodium merely with formula, and long-term application also can cause and is discharged into that the element ratio deviation in farmland is excessive forms pollution! So these methods all be unable to do without heating concentrate, to reach the object of far arranging potassium.In these documents, all do not mention and how the variation of institute's with medicament in treatment formulations and the nutriment in a fertilizer in farmland are changed to the problem how demand is linked up with, do not mention yet and how without heating concentrate process, just waste water work can be met to the scheme of the fertilizer of the fertile part changes in demand in farmland.

From the message of Chinese sewage treatment project net 2008-12-2913:12:34 issue, learn again:

The aplanatic Paper Co., Ltd in Zhanhua County, Shandong Province adopts the wastewater treatment mode on " sealing discharge, improvement alkali ground, purify waste water, recycle ", artificial swamp method with plantation reed is administered paper waste, spring in 2002, reed purifies area and is increased to 5300 mu, through Bureau of Environmental Protection of Shanxi Province, detect, circulation end water COD(chemical oxygen demand) and BOD5(five-day BOD) than water inlet concentration, all reduce more than 50%, reach respectively 1500mg/L, 200mg/L, reached reuse production standard more completely.Past each ton of paper needs water 100 sides,, only with 4 side's water, has declined 96% now.Through province environmental administration, measure, aplanatic paper industry has been accomplished the standard of trade effluent " zero release " completely, and meanwhile, the alkaline land soil fertility improveing after 3 years can grow wheat.

But the artificial swamp method of aplanatic papermaking company limited still has technology flaw, one, factory must be near rural area; Its two, have large stretch of soil to become wetland; Its three, wetland is limited by the region at wetland place to the decontamination effect improving of institute's effluent because in the region freezing, winter both cannot draining, plant does not grow yet; Its four, effect probably can not be lasting because when for a long time to the waste water that enters fixed inorganic salt in plot, will cause the difference of soil salt and plant demand salt, platoon is long cycling time one, plant-growth just can not be luxuriant as the discharge initial stage.

From then on a piece of writing is reported in fact, if can find, this embodiment promotes the problem that will inevitably run into, i.e. " improve alkaline land soil fertility after 3 years can grow wheat ", may I ask so: as when not had enough saltingss to do wetland schedule for it by popularization factory periphery, when soil replants wheat, promoted the waste water of factory again to where arranging?

In addition, or/and the degreasing of fiber crops and yarn thereof, fabric, bleaching are also the same with pulping and paper-making, there is identical technology and an environment difficult problem in the cotton in the degreasing of congener fiber, bleaching technology field; Sub-products production field in this plant-fiber product production field, also have in recent years large progress, if CN 200910011394.X(is for the nano material composition of bleaching cellulose fiber fabric), the cold dome preparation technology of CN200910025199.2(absorbent cotton) etc.But these are progressive, be also less than the breakthrough of the matter that can make to discharge the useful field property of glassware for drinking water.

As the saying goes " rich water do not flow other people field ", vegetable fibre degreasing or and delignification, bleaching effluent in have fertilizer, particularly containing being of value to the lignin of plant-growth and the complicated organism such as degradation products at different levels thereof, thus vegetable fibre degreasing or and delignification, bleaching effluent can become a kind of resource of organic composite fertilizer processed! But why vegetable fibre degreasing or and delignification, bleaching effluent can not be for a long time directly into field? its answer is: vegetable fibre degreasing or and delignification, bleaching effluent in water in the ratio of processable inorganic nutritive element general not with most vegetation or and required fertile part in farmland in water in processable inorganic nutritive element ratio match! Specifically, vegetable fibre degreasing or and delignification, bleaching effluent in generally lack the required major element of plant-growth " nitrogen, phosphorus or and potassium etc. ", do not contain or seldom contain the required trace element of plant-growth " manganese, zinc, copper, molybdenum etc. ", and there is the required major element of too much plant-growth " sodium, chlorine or potassium ", have too much or fluctuation contain plant-growth required in, trace element " calcium, magnesium, sulphur, iron, aluminium ", be rich in the required a large amount of organic matters of plant-growth.Though so vegetable fibre degreasing or and delignification, bleaching effluent in have fertilizer, but because disappearance and the ratio of its contained nutritive ingredient kind is unworthy of, add in water wherein processable inorganic salt concentration conventionally not in safely use scope, therefore it does not directly just have beneficial field property; Add the traditional forms of enterprises and mostly production equipment is arranged on to the cities and towns away from rural area, this just makes space length become rich water to enter the obstruction of field scheme.Special needs to be pointed out is, in the water that technology is in the end discharged now, the sodium-chlor that contains 2 ~ 3 ‰ upper limits that can bear far above vegetation is or/and sodium sulfate, if this kind of waste water enters farm environment, can bring the dispirited until dead of the salinification in soil and vegetation.

The quick degradating trend of persistence for containment China water surrounding; People's Republic of China's Environmental Protection Department has been promulgated bulletin 2008 No. 26; be the standard GB 3544-2008 of the People's Republic of China (PRC) " slurrying causes paper industrial water pollutant emission standard "; 4.3 regulations wherein: " from 1 day August in 2008, the Sewage Water Emissions of newly-built enterprises in pulp and paper industry execution list 2 regulations was limited the quantity of.", described " Sewage Water Emissions of newly-built enterprises in pulp and paper industry execution list 2 regulations is limited the quantity of ", make a copy of in as shown in Table 1 below:

(table 1)-newly-built papermaking Sewage Water Emissions Limited Doses and the unit product base platoon water yield

Unit: mg/L (except pH value, colourity, dioxin)

But this GB 3544-2008 standard, also against in the flaw of promulgating the road original intention that will walk Green Sustainable of this standard, its problem is: due to paper pulp processed or/and the pollutent project indicator value in the water that copy paper produces all far away higher than the prescribed value of GB3544-2008, enterprise is for making to limit matter, the discharge water of limiting the quantity of is up to standard, just must carry out cleansing and recycling repeatedly to water, in this course, not only can make business processes cost rise higher, consume a large amount of energy, and can make NaCl in this water or/and water-soluble inorganic salt content fast rise such as Na2SO4, reach far away higher than tolerant 2～3 ‰ the value of vegetation, cause this water cannot be used directly to field irrigation, can not be by production process cycling and reutilization.And NaCl in relevant this water is or/and the content of the inorganic salts such as Na2SO4, this standard does not relate at all, this standard does not consider that how this being discharged to water makes the high value resource utilization recycling of cheap problem, it is only the technical scheme that has adopted the end treatment of hard blocking, do not meet the Sustainable development new concept of green manufacturing, so be unfavorable in the long term, the Sustainable development of low-carbon (LC) and recycling economy; GB 3544-2008 standard is only also the caving-in bash under the technical qualification of present stage.

In " National Development and Reform Commission, the Ministry of Finance are about advancing the suggestion of garden circulationization transformation " (send out to change to encircle and provide [2012] No. 765) of in March, 2012 National Development and Reform Commission of the 21， People's Republic of China (PRC), Ministry of Finance issue, mention:

" (three) industry link circulationization
