Abstract
The invention relates to three-section closed circuit cold soaking paper making pulp and a production method thereof. The three-section closed circuit cold soaking paper making pulp is characterized by comprising the following raw materials by weight part: 1000-1600 of cotton stalks or wood shavings or wheat straws or straws, 100-300 of sodium hydroxide, 8.3-12.3 of sulfonated succinate, 1-1.5 of secondary alkane sulfonate, 160-360 of sodium hypochlorite and 1-5 of neutral reactant, namely sodium hydrogen sulfite and has the advantages of reasonable and particular material batching, simple and practical production method, good pulp quality produced, low cost and no pollution; and the whiteness of the pulp can reach above 70 percent. Therefore, the invention relates to ideal paper making pulp and a production method thereof.
Description
One, technical field:
The present invention relates to a kind of paper making pulp and production method thereof, particularly a kind of three-section closed circuit cold soaking paper making pulp and production method thereof.
Two, background technology:
At present, the paper mill adopts sulfate process, Ammonium Sulfite Method etc. that the method slurrying of pollution is arranged mostly, and these methods exist many problems, such as not only produce black liquor in the High Temperature High Pressure digestion process, harm such as organic solid and the blast of generation rotary spherical digester, and produce foul gass such as methyl mercaptan and methyl sulfide.The stink of methyl mercaptan is very big, and the low highly volatile of boiling point, often all can smell in 1.5 kilometer range near the paper mill, and the surrounding resident life is seriously influenced.In addition, also waste coal, waste electric power causes black smoke, contaminated environment, and this is the deficiencies in the prior art.
Three, summary of the invention:
The objective of the invention is to invent a kind of three-section closed circuit cold soaking paper making pulp and production method thereof, this production method is not subjected to the influence of seasonal variations, be the cold soaking pulp-making method, this method is safe and reliable, easily operation, do not injure human body, do not waste energy, cost is low, the efficient height, the rate of winning a prize can be up to more than 75%, in order to overcome the deficiencies in the prior art.
Purpose of the present invention can reach by following embodiment: the weight of the raw material of this three-section closed circuit cold soaking paper making pulp is divided into cotton stalk or wood shavings or wheat straw or straw 1000～1600, caustic soda 100～300, sulfosuccinate 8.3～12.3, Seconary Alkane Sulphonate Sodium 1～1.5, clorox 160～360, the neutralization reaction agent is a sodium hydrogensulfite 1～5.
The production method of this three-section closed circuit cold soaking paper making pulp is with cotton stalk or wood shavings or wheat straw or straw dedusting chopping, add caustic soda, sulfosuccinate and Seconary Alkane Sulphonate Sodium, fully stir, the preimpregnation raw material, send into the reaction platform,, roughly grind dehydration through reaction in 36 hours, recovery effect waste liquid flows among the recovery pond A, with utilization to be recycled; The raw material that takes off behind the liquid is that clorox flow into together and is in harmonious proportion in the reaction tank in company with the secondary soup, carry out 3 hours the reaction of discoloring, after question response is finished, coarse fodder is finish grinded and press filtration, recovery effect waste liquid flows among the recovery pond B, with utilization to be recycled, fine fodder adds sodium hydrogensulfite, stirs, carry out neutralization reaction, take off the dried finished product slurry of hydraulic pressure, the waste liquid of extruding flows among the recovery pond C, with utilization to be recycled.
Advantage of the present invention is that batching is reasonable, fastidious, and production method is simple, practical, and the pulp quality of producing is good, and cost is low, and pollution-free, and the pulp brightness of producing can reach more than 70%; This method is not subjected to the influence of seasonal variations, is the cold soaking pulp-making method; This method is safe and reliable, and operation does not injure human body easily, does not waste energy, and cost is low, the efficient height, and the rate of winning a prize can be a kind of three-section closed circuit cold soaking paper making pulp and production method thereof up to more than 75%.
Four, description of drawings:
Fig. 1 is technological process of production figure.
Five, concrete real-time mode:
Be 3 embodiment of parts by weight of raw materials of the present invention below:
1, the weight of the raw material of this three-section closed circuit cold soaking paper making pulp is divided into cotton stalk or wood shavings or wheat straw or straw 1000, caustic soda 100, sulfosuccinate 8.3, Seconary Alkane Sulphonate Sodium 1, clorox 160, the neutralization reaction agent is a sodium hydrogensulfite 1.
2, the weight of the raw material of this three-section closed circuit cold soaking paper making pulp is divided into cotton stalk or wood shavings or wheat straw or straw 1300, caustic soda 200, sulfosuccinate 10.3, Seconary Alkane Sulphonate Sodium 1.25, clorox 260, the neutralization reaction agent is a sodium hydrogensulfite 2.5
3, the weight of the raw material of this three-section closed circuit cold soaking paper making pulp is divided into cotton stalk or wood shavings or wheat straw or straw 1600, caustic soda 300, sulfosuccinate 12.3, Seconary Alkane Sulphonate Sodium 1.5, clorox 360, the neutralization reaction agent is a sodium hydrogensulfite 5.
The production method of the foregoing description is held and is not described in detail with the scheme part.
Production method of the present invention is the production method that chemistry combines with physics, strong oxidizer and penetration-assisting agent are also used simultaneously in the pulping process, make strong oxidizer quickly with raw material in lignin fully contact, rapid osmotic is also carried out oxidation reaction, and lignin is oozed out in born of the same parents' layer.Add the secondary soup then, with the coloring matter in the raw material remove and in and raw material in alkaloid substance.Therefore, production method water consumption of the present invention is few, and water only plays the dilution medicine and soaks into raw material in whole process.In order to make medicine can bring into play its maximum effect, the present invention has adopted the method for waste liquid cycling and reutilization, because the waste liquid property of medicine is low and dose is few, so also need to add a spot of water and a spot of medicine when utilizing in waste liquid again.
