Abstract
The invention is about the no braising biochemical solvent serial soaking cat-crack loop pulping. The plant with the fiber is the material. The process includes: refinement of the material, removal of the impurity, pulping, separation of pulp. The pulping process is soaked serially for 3-6h in the soak with the enzyme at the situation of the normal press and not above the 50DEG C. The process is in the normal situation and not generating the waste.
Description
Technical field:
The present invention relates to pulp technology for making paper, particularly a kind of no-boiling biochemical solvent continuous dipping catalyst cracking circulating pulp-making method.
Background technology:
Papermaking technology is invented by Chinese, history in several thousand has been arranged so far, the key link of papermaking is slurrying, traditional pulp-making method need carry out boiling with fibrous plants under high-temperature and high-pressure conditions, need add a large amount of alkali during boiling, cooking process slurrying produces a large amount of black liquor, and black liquid is the pollution sources of intractable.
Solvent pulping is external technology newly developed, mainly be with the slurrying of alcohol organic solvent method, the temperature of general reaction is all more than 100 ℃, the time of reaction all needs several hrs, biology enzyme slurrying also obtains certain achievement, but also there are a lot of difficult problems in these technology, can't realize suitability for industrialized production (see for details " pulping and paper-making cleaner production new technology) " the ISBN 7-5025-4716-9/X.323 of Chemical Industry Press, Pg5-33; Pg67-73).
Chinese patent discloses the method for preparing paper pulp under two kinds of normal temperature, the condition of normal pressure: " medicine catalytic reaction string is made the method for paper pulp under the normal temperature and pressure " (application number: 200310105602.5); " clean pulping catalyst and technique for applying thereof " (application number: 200310115531.7).The method of catalysis has all been adopted in these two patent applications, because the reaction condition gentleness does not produce black liquor, but above-mentioned two technology all are batch process production from technology analysis, and its catalytic pyrolyzing agent is chemical agent, and does not contain biologic product.
Summary of the invention:
The objective of the invention is to overcome the prior art defective, a kind of no-boiling biochemical solvent continuous dipping catalyst cracking circulating pulp-making method is provided.
Purpose of the present invention realizes by following scheme:
A kind of no-boiling biochemical solvent continuous dipping catalyst cracking circulating pulp-making method, with the fibrous plants is raw material, its technical process comprises that refinement, removal of impurities, slurrying, the slurries of raw material separate, described pulping process is at normal pressure and is not higher than under 50 ℃ the condition, continuous dipping catalyst cracking is finished in containing the soak of biology enzyme, the time of staying of raw material in soak is 3～6 hours, and the isolated liquid part of slurries is assorted active ingredient and recycled after purifying;
Described feed liquid separation process be will starch earlier, the liquid crude separation, more isolated slurry is partly carried out cold spray and discongests, carry out spiral at last and extrude separation;
The purification of the isolated liquid of described slurries part be with the isolated whole liquid collectings of slurries get up to carry out slightly, two filtrations of essence, till the filtrate no suspended substance;
Described continuous dipping is meant raw material is placed the continous mode conveying machinery that from going into to expect discharging, raw material moves all the time, guarantees that the time of staying of all raw materials in soak is 3～6 hours in soak in course of conveying;
Described cold spray is discongested and is meant slurry is imported in the airtight spraying pot, charges into compressed air, and pressure reaches fast pressure relief behind 0.5～0.8MP, and slurry is ejected in the jetting storehouse;
Described continous mode conveying machinery is a scraper conveyor;
Described continous mode conveying machinery is a spiral inclined tube-type conveyer.
What the present invention adopted is biology enzyme solvent continuous dipping catalyst cracking defibre and lignin and colloidal type material, do not need High Temperature High Pressure, the course of reaction gentleness, do not produce black liquor in the pulping process, solvent after filtration, recycle behind the fine cleaning, not producing waste water, realize zero-emission, is the substantive breakthroughs of paper technology; In addition, method slurry yield height of the present invention, paper pulp is easy to rinsing, and the later stage middle section water is more easily handled, a large amount of energy savings.
The specific embodiment:
A kind of specific embodiment of the present invention is as follows: 1, select materials; 2, blank; 3, screening impurity elimination; 4, continuous dipping catalyst cracking; 5, feed liquid is separated; 6, carry spraying pot; 7, cold spurting discongested to jetting storehouse; 8, spiral squeezes and send machine to carry; 9, press master extracts solution.Solution reuse after thick, smart two steps filter, purify; Paper is played, grinds, sieves, washes, selects, floats, copied to slurry.
Described selecting materials is to select fibre-bearing material that be fit to make paper pulp for use, as grass family straw fiber: wheat straw, straw, reed, cornstalk, sorghum stalk, cotton stalk, bagasse etc.; Bast fiber class: jute, flax, hemp etc.; Lignocellulose: red building, poplar, comprise white poplar, the living poplar of speed etc., through blank grass blade is prescinded, the material that cuts is sent in the continuous dipping conveying machinery through the screening impurity elimination, this machinery can be scraper-type, also can be screw type, should guarantee in the whole transportation process that material stopped in soak 3～6 hours, temperature is not higher than 50 ℃, should not be low excessively yet, temperature is higher, the speed of catalytic pyrolysis is faster, and the composition of soak can have multiple, can select chemical agent for use, also can select the composite enzyme biological agent that contains for use, recommend a kind of prescription part by weight: enzyme: 3～6%; Activator: 1～5%; Tween: 1.5～3.5%; Bleeding agent: 2～5%; Sodium metasilicate: 1.8～3.5%; The FT-1 catalyst aid: 3～9%, all the other are water;
Separate through carrying out slurries behind the continuous dipping catalyst cracking, send into cold spraying pot again and spurt and discongest, spraying pot charges into Pressure control behind the compressed air at 0.5～0.8MP, and pressure reaches fast pressure relief behind 0.5～0.8MP, and slurry is ejected in the jetting storehouse;
Thick slurry after discongesting deliver to press master carry out slurries segmentations from, after enter conventional paper pulp processing technology, slurries separate and the isolated solution of press master after filtration impurity elimination and be cleaned into clear liquid after reuse.
