Abstract
The present invention is plant stalk pulping process by means of violent reaction between hydrogen peroxide and excessive alkaline matter to decompose plant stalk. After wheat straw, rice straw, corn stalk, cotton stalk, bagasse or other plant material is crushed and water soaked, sodium hydroxide and small amount of assistant are added, the system is heated to boil, and hydrogen peroxide is added to produce drastic reaction, so that the released energy decomposes the plant material into cellulose and lignin. Through further pulping and washing to eliminate lignin, pulp is produced. The said process is simple and convenient, and has no exhausted black liquor, easy treatment of pulp washing water for reuse, low power consumption and low cost.
Description
Technical field: the present invention is that the paper-making pulping field does not have the low-cost slurrying new results of black liquor
Background technology: utilize wood pulp papermaking China to lack forest resourceies, utilizing discarded careless class pulping and paper-making is the unique in the world characteristics of China.But the black liquor Heisui River serious environment pollution that careless class slurrying produces.800,000,000 peasants are seeing that tangerine bars such as a large amount of wheat straws that tens00000000 mu of soils produce, straw, corn can not utilize, and just burn in a large number.China's every year, a large amount of again import paper and papermaking material were the major issues of benefiting the nation and the people so utilize plant stalk papermaking.Everybody is at the no black liquor of idea development Heisui River, low-cost straw pulp.Present various pulping process is a lot, much is that investment is big, complex process but anatomize, so can not large-scale popularization use.
Summary of the invention: utilize hydrogen peroxide to meet the excesses of basic material, the characteristic that causes violent decomposition is used for the method for pulping and paper-making, invest little, output greatly, the technology simple possible.
Hydrogen peroxide has another name called Liquor Hydrogen Peroxide, hydrogen peroxide, molecular formula H
2O
2, molecular weight 34.0158, proportion 1.438 utilizes it to meet the excesses of basic material and can cause violent decomposition reaction, and discharges heat energy even explode this principle.Alkaline material such as NaOH etc. will be strengthened in a certain proportion of water, add plant stalk or other material of pulverizing in proportion, mix and heat, accelerate decomposition reaction velocity, just formed strong alkaline substance, add an amount of hydrogen peroxide again, violent decomposition reaction just takes place, and discharge heat energy.In this course comminuted plants tangerine bar and other material have all been carried out sufficient decomposition division,,, removed lignin, nursed one's health into the good high-quality straw pulp of the high whiteness of beating degree through grinding the making beating washing with fiber and lignin decomposition and separation.In this production process, compare with other pulping process way, economize on electricity economizes coal, cost is low, water is few, and this production principle and technology also are fit to the slurrying production of other material.
At occurring in nature hydroxide, peroxide, acidic oxide, basic anhydride are arranged, not salify oxide, amphoteric oxide, superoxides etc., and some kinds are all arranged in each oxide.In straw pulp, can not use entirely, should be specific to certain product.As our the straw pulp method of development is to utilize hydrogen peroxide and NaOH, and utilizing hydrogen peroxide to run into the excesses of basic material is NaOH etc., is used for slurrying just the principle of violent decomposition and release heat energy takes place.Suitably add auxiliary agents such as stabilizing agent in the production, just can decolour and brighten, produce the high-quality straw pulp.
CODcr has also been cut down in the violent decomposition of hydrogen peroxide in a large number, thereby this pulping technique do not produce black liquor, and it is neutral that pH value is, and treated pulp washing water can be recycled, but also qualified discharge.If pay attention to filtering, prevent to run slurry, spillage pulping rate height, body refuse seldom is convenient to cleaner production.Now produce in batches, demonstration project is arranged.
Embodiment 1
Be provided with agitator, in the container that can heat, add earlier and can moisteningly soak into the required water of tangerine grass, amount by tangerine bar hay 3% to 12% adds NaOH again, the an amount of stabilizing agent that adds, decolouring auxiliary agent such as is brightened and is stirred evenly, heat, it is better to be little shape that boils, and heats up to add the wheat straw straw material that adds metering in the thermal agitation, delay by the amount of straw hay amount 4% to 13% from the bottom of container again and add the needed hydrogen peroxide of violent decomposition, produce violent decomposition reaction immediately, note preventing to overflow, insulation continues decomposition reaction again, it is soft that straw pulp becomes, after the defibrination washing, it is good just to produce fiber again, the beating degree height has the high-quality straw pulp of certain whiteness.
Embodiment 2
In being provided with the container that agitator can heat, add earlier and can moisteningly soak into the required water of straw grass, add NaOH again by the amount of straw hay 3% to 12%, auxiliary agent such as add that in right amount stabilizing agent, decolouring brighten.Intensification adds the straw material that adds metering in the thermal agitation, by 4% to 13% amount of straw straw hay amount from the bottom of container the slow needed hydrogen peroxide of violent decomposition reaction that adds, produce violent decomposition reaction immediately, notice that slow adding prevents to overflow, violent decomposition reaction finishes back straw straw pulp and becomes soft, produces just after the defibrination washing that fiber is good, beating degree is high again, the high-quality straw pulp of certain whiteness is arranged.
Embodiment 3
In being provided with the container that agitator can heat, add earlier and can moisteningly soak into the required water of straw grass, press the amount repeated hydrogenation sodium oxide molybdena of straw hay 3% to 12%, auxiliary agent such as add that in right amount stabilizing agent, decolouring brighten.Intensification adds the corn stalk that adds metering in the thermal agitation, by 4% to 13% amount of straw hay amount from the bottom of container the slow needed hydrogen peroxide of violent decomposition reaction that adds, produce violent decomposition reaction immediately, notice that slow adding prevents to overflow, reaction decomposes finishes back straw grass and becomes soft, produces just after grinding the making beating washing that fiber is good, beating degree is high again, the high-quality straw pulp of certain whiteness is arranged.
Embodiment 4
In being provided with the container of agitator prodigiosin heating, adding earlier can the moistening required water of reed forage that soaks into, and adds NaOH again by the amount of reed hay 3% to 12%, auxiliary agent such as add that in right amount stabilizing agent, decolouring brighten.The reed forage that adds metering in stirring stirs evenly, heating then heats up, again by 4% to 13% amount of reed hay from the bottom of container the slow needed hydrogen peroxide of violent decomposition reaction that adds, produce violent decomposition reaction immediately, notice that slow adding prevents to overflow, reaction decomposes thoroughly back reed straw grass becomes soft, produces just after grinding the making beating washing that fiber is good, beating degree is high again, the high-quality reed pulp of certain whiteness is arranged.
More than the consumption of various materials can decide grasp flexibly according to the degree of the quality of tangerine bar and violent decomposition reaction and the suitable feelings of soft whiteness situation of slurry.
