Abstract
The present invention relates to a method for grass unpolluted pulping and by-product reclaiming. The present invention relates to the following steps that the grass can be sufficiently and reasonably processed by using the technology conforming to ecological environment requirements so that paper pulp and feed are manufactured. Fine grass pieces (raw materials in paper industry) and fine grass slag (raw materials in feed industry) can be manufactured by that the grass is sliced, sorted, etc., trivoltine (water penetration, softness and washing) treatment is carried out to the fine grass pieces, the dryness degree of the grass pieces can reach 25 to 30 %, and high quality grass pulp can be manufactured through the process of secondary milling treatment, etc. The fine grass slag is pulverized, grass powder is used as base materials, components of supplementary materials, composite additive agents, etc. are added in, and a series of high quality fiber feed can be manufactured through full mixing, shaping, cooling, drying, etc.
Description
The present invention relates to careless class development and use, particularly adopt free of contamination technology manufacturing paper pulp and energy-conservation technology will pay the fiber feedstuff that product is made high-quality.
Annual agricultural goes up the various careless class that generates and reaches several hundred million tons, basically all unprocessed, the cultivated also field of burying of part a spot ofly is used for papermaking etc., and a large amount of then goes out of use, even burn, for a long time, though make great efforts tackling key problem, also do not find science, meet benign ecological cycles, way capable of being industrialized.
The careless class pulping process of tradition, main have soda processes, lime method, sulfurous acid nanofarad, an ammonium sulfite etc., more than several system oar methods all be through adding chemicals in boiling vessel through boiling, chemical treatment, its cooking waste liquor need drop into the great number fund, carry out liquid waste processing, the waste liquid that is discharged is also difficult up to standard, and as the not treated waters that is discharged into, the environmental pollution meeting that then causes is even more serious.
Pair product (waste material---the careless slag after the careless class process section dedusting) with careless class pollution-free pulping, by eating the nutritive index that careless livestock is fed and expects, carry out recycling treatment, method disassociation grass fiber with machinery, allocate additive again into, be processed into the feed product of series, this series products has higher use value and application prospects.
The systems approach of grass class pollution-free pulping and pair product resourceization thereof still belongs to initiative so far.
The objective of the invention is to:
A kind of method that realizes the pollution-free manufacturing pulp production technology of careless class and pay product resourceization is provided.
The method of pollution-free careless class slurrying is:
1. grass as raw material is divided into refining blade and refining careless slag two parts through collection, storage, cut-out, dedusting, screening.
A. refining blade: be mainly careless bar position, length is 20～40 millimeters, accounts for 85～90% of herb.
B. refining careless slag: be mainly blade of grass, the tip, fringe, film etc., account for 10～15% of herb.
2. refining blade is handled through three changing (clean, infiltration, softening), washes with water, soaked 20～40 fens, through permeate, stripping 8～15% solution extracts, making the blade mass dryness fraction reach 25～30% through dehydration again becomes the straw pulp raw material, is stored in the feed bin.
3. the blade of mass dryness fraction 25～30% is worn into the SR ° of straw pulp about 50 degree through fiberizer.
4. with pulp machine or paper machine straw pulp is produced commodity.
The method of refining careless slag resource is:
1. will make with extra care careless ground-slag with pulverizer and be broken into powder below 5 orders.
2. preparation compound additive: with function preparation (as preparations such as organic selenium, organic calcium, phosphoric acid urine) and carrier (as refining grass meal below 80 orders, pomace powder etc.) by (1～20): (99～80) are formulated.
3. powder and compound additive are mixed by 〉=90 :≤10 weight ratio, or reshaping, drying is made high-quality grass fiber feed.
Good effect after invention is implemented is:
1. when developing the raw material of industry of high-quality, can eliminate owing to handle a large amount of careless classes, and environmental problem such as the atmosphere that produces is contaminated.
2. can in numerous zones, reduce or eliminate because papermaking wastewater discharges the severe contamination to the water source, and can promote the development of paper industry.
3. can significantly increase the number of animals raised of the careless livestock of food, improve raise competence, promote Developing of Animal Industry.
The product that application the present invention can make has:
1. the refining blade raw materials of industry such as () papermaking;
2. the refining careless slag raw materials of industry such as () feeds;
3. high-quality paper pulp;
4. high-quality fiber feedstuff.
Embodiment:
Get 1500 kilograms of wheat straws (or straw) through removal of impurities, dedust soil, section, sorting must be made with extra care about 1150 kilograms of blade, about 350 kilograms of refining careless slag.
1150 kilograms of refining blades through dewatering, the blade mass dryness fraction being reached about 30%, make about 1000 kilograms of paper pulp through the grinding of secondary mill again through three change processing, produce fluting medium with it.
The leading indicator of product: quantitatively: 160g/m
2± 8, tightness: be not less than 0.50g/m
2, fracture length: be not less than 3750m, ring crush intensity: be not less than 7.7Nm/g.
Add 8 kilograms of 199 kilograms of fresh grain stillages and compound additives after 350 kilograms of refining careless ground-slags are broken, fully mix aftershaping, dry about 400 kilograms of the product that gets.
The leading indicator of product: moisture :≤13%, crude protein: 〉=12%, slightly refer to fat 〉=4%.
Claims (1)
1. the method for careless class pollution-free pulping and byproduct resource thereof, it is characterized in that: the grass as raw material process is gathered, store, cut off, dedusting, screening is divided into refining blade and refining careless slag two parts, wherein refining blade is mainly the culm position, length is 20～40 millimeters, account for herb 85～90%, change promptly clean through three, infiltration, the softening processing 20～40 minutes, through infiltration, ooze out 8～15% solution extracts, make the blade mass dryness fraction reach 25～30% through dehydration again, wear into the SR ° of straw pulp about 50 degree through high-density paste mill then, straw pulp is made paper and cardboard with pulp machine or paper machine;
Refining careless slag: be mainly blade of grass, the tip, fringe, film etc., account for 10～15% of herb, through pulverizing powder, press powder again: compound additive=〉=90: after≤10 the weight ratio mixing, make serial high-quality fiber feedstuff after moulding, cooling or the drying;
