Abstract
The present invention relates to a biologically pulping process for making paper, which comprises a step of cutting off raw materials, a cooking step and subsequent steps. The present invention is characterized in that before cooking, active biological liquid is cultured, and partial cultured active biological liquid is sprayed on raw materials which are cut off until the raw materials are totally moistened; a spherical digester is placed, and simultaneously, partial active biological liquid is added to the spherical digester; after the spherical digester rotates for about 30 min, gas is introduced and the spherical digester is cooked. The present invention has the advantages of reasonable design, feasible technology, little biological strain quantity, short technological process time and little equipment investment, and is favorable to reduction of papermaking production cost. The cooked raw liquid can be reused, and does not need to be further treated.
Description
Technical field: the invention belongs to the paper technology scope, relate to a kind of bio-pulping process of paper industry.
Background technology: the history of existing centuries of paper industry, bigger development is arranged again in recent decades, still, its pulping process but develops slower, still acid-base methods that adopt more.The process of this slurrying not only needs to consume a large amount of acid, alkali, salt etc., paper cost height; And will discharge in a large number people, animal and the harmful waste water of crops, the cod index generally all reaches 2-3 ten thousand, and intractability is big, and environmental pollution is particularly very serious to phreatic pollution.The applicant had once applied for the patent of invention of " a kind of pulping Process for papermaking straw pulp " November calendar year 2001, application number is 01135183.7, this patent disclosure before boiling, carry out the bio-pulping process of biofermentation earlier, comparatively effectively overcome the existing drawback of sour subtraction pulping process.But, in this technology, raw material per ton need be with 1-3 kilogram biological inoculum in seal groove, under the what 10-30 degrees celsius anaerobic fermentation 1-10 days, not only need be big with the biological inoculum amount, the pulp preparing process time is long, and needs to build more fermentation tank, invest morely, be unfavorable for reducing the paper cost.In addition, the also not convenient usefulness of the stoste after its boiling also needs to carry out certain processing.
Summary of the invention: the objective of the invention is to have the existing above-mentioned drawback of biofermentation pulping process technology now, and a kind of improved papermaking bio-pulping process is provided for overcoming.This technology is to improve to realize on the basis of existing biofermentation pulping process technology, it comprises raw material, cut-out processing and boiling and subsequent handling thereof as forages such as wheat straw, straw, cotton stalk, bagasse and wood chip, it is characterized in that before boiling, carrying out earlier the cultivation of active bio liquid, after promptly in culture pond, adding water, admix brown sugar, maize flour and wheat face, add in lactic acid bacteria, fermentative microflora, the aspergillus flora one or more again, anaerobism was cultivated 5---7 days under the 20---45 degrees celsius; Earlier the cultured active bio liquid of part is sprayed on the raw material of handling through cut-out, all moistening to raw material, reinstall rotary spherical digester, in rotary spherical digester, add part active bio liquid simultaneously, treat that rotary spherical digester turned round cardinal principle after 30 minutes, boiling is carried out in ventilation again.
The cultivation of said active bio liquid, the weight portion proportioning of its water, brown sugar, maize flour, wheat face and biological inoculum can be: water 20000, brown sugar 8-12, maize flour 12-18, wheat face 12-18, biological inoculum 4-8.
Preferred weight portion proportioning is: water 20000, brown sugar 10, maize flour 15, wheat face 15, biological inoculum 5-6.
The weight portion proportioning of the active bio liquid of said raw material and spray and adding rotary spherical digester can be: raw material 1000, active bio liquid 2000-3000.
For further reducing the consumption of biological inoculum, reduce production costs said boiling, stoste after its boiling can play back to active bio liquid culture pond, mixes with former active bio nutrient solution, and moisturizing in the pond, to suitable, as the active bio nutrient solution use of inferior batch of material cooking with commercial weight.
For alleviating equipment corrosion, the long-time normal operation of protection equipment before the ventilation boiling, can add the ammoniacal liquor of a small amount of 1.5-2% or the urea of 2-4% in rotary spherical digester.
The present invention is reasonable in design, feasible process, and the biological inoculum consumption is little, and the technical process time is short, and equipment investment is few, helps reducing the paper cost, and the stoste after the boiling can be utilized again, need not to be for further processing.
The specific embodiment:
Embodiment 1: inject 20 tons in water to active bio liquid culture pond, admix 10 kilograms in brown sugar, 15 kilograms of maize flours, 15 kilograms in wheat face adds lactic acid bacteria 5-6 kilogram, and culture pond is sealed, anaerobism was cultivated 6 days under cardinal principle 30 degrees celsius, promptly made the active bio nutrient solution; Get 1 ton of above-mentioned active bio nutrient solution, spray 1 ton on the wheat straw forage that cut-out is handled well, and with the forage rotary spherical digester of packing into, other gets above-mentioned active bio nutrient solution and adds rotary spherical digester for 1.5 tons, opens the rotary spherical digester running 30 minutes substantially, makes forage be able to abundant enzymolysis; Fed the steam boiling then 3 hours, and promptly made papermaking magma, this papermaking magma is conventional defibrination, machine hand's preface through the rear portion, can copy the system toilet paper.
Embodiment 2: according to embodiment 1, wherein brown sugar is 8 kilograms, and maize flour is 12 kilograms, and the wheat face is 18 kilograms, and 8 kilograms of zymophytes were cultivated 5 days in 45 degrees centigrade of anaerobism of cardinal principle, and all the other are with embodiment 1.
