Abstract
The invention relates to a wet strength paper treatment technology. Hot water and wet strength paper are added to a pulp kneader to pulp the wet strength paper, and heavy metal impurities contained in the wet strength paper are removed after the wet strength paper is pulped; and pulp is condensed by spiral condensing equipment, is heated by spiral heating equipment and enters a thermal dispersion machine to be further torn, diluted and beaten to prepare fiber pulp. The wet strength paper treatment technology effectively improves the pulping yield of the wet strength paper, lessens the waste, reduces the production cost and improves the economic benefits.
Description
Technical field
The present invention relates to a kind of wet strength paper treatment technology, relate in particular to a kind of size degradation wet-strength paper ability strong, become the high wet strength paper treatment technology of pulp yield.
Background technology
Along with the development of world's paper industry, cause the paper resource in short supply day by day.The waste paper comprehensive utilization improves the only way which must be passed that the waste paper recycling rate has become global paper industry development.In the waste paper that is recovered in the market, wet-strength paper occupies certain ratio, this kind paper wet strength height, and paper pulp is resolved in very difficult fragmentation.If paper plant adopts conventional Waste Paper Handling technology, when together handling, be difficult to the size degradation pulping with other waste paper, discharge with slag mostly in process of production, cause a large amount of fiber loss, the pulping rate is very low, the wet-strength paper less than 20% of energy size degradation pulping.As adopt traditional boiling method, and fiber degradation is serious in the digestion process, and fiber destruction is bigger, can produce a large amount of cooking waste liquors in digestion process, increases water consumption and waste water treatment amount greatly, becomes pulp yield also lower.China Patent No. 200810015583.X discloses and has a kind ofly done, wet strength paper dissociation agent and degradation technique thereof, by adding dissociate agent to do, wet-strength paper degrades, remove impurity and obtain slurry through dehydration, making beating, screening again, though raising to a certain extent slurry yield, but need long soak time, production efficiency is low, and can produce pollution to environment, unfavorable environmental protection.
Summary of the invention
The invention provides a kind of, wet strength paper treatment technology that pulping rate high strong to wet-strength paper size degradation ability.
In order to solve the problems of the technologies described above, the present invention takes following scheme:
A kind of wet strength paper treatment technology, may further comprise the steps: (1) adds hot water and wet-strength paper in pulper, and hot water is 85～90% by weight percentage, wet-strength paper is 10～15%, and the hot water temperature is 55-65 ℃, the size degradation time is 15～20 minutes, and wet-strength paper is carried out size degradation; (2) heavy metal class impurity is removed in purification; (3) the spiral concentrator concentrates slurry, must moisturely by weight percentage be 68～72% slurry; (4) spiral heating equipment heating, control temperature make slurry further soften, moisten and rise between 90～110 ℃; (5) slurry enter heat dispersion machine further torn up after dilute, pull an oar fine slurry.Described pulper is that shell is equipped with electromagnet equipment, the hole diameter of sieve (perforated) plate is the pulper of 20～30mm, selects the wide-aperture sieve plate of 30mm for use, can realize not entered next operation by a scrap of paper of size degradation form slurry by sieve plate, can not discharge with slag, has reduced waste.Described heat dispersion machine is selected the strong big flute profile heat dispersion machine of the ability of tearing up for use, chooses dish tooth model and be 086 or 087 heat dispersion machine, further tears up slurry or not by the wet-strength paper of pulper size degradation pulping, has reduced waste, has improved slurry yield.
The fine slurry of gained of the present invention can be made into the high-quality fibrous raw material of producing craft paper, has improved economic benefit; Wet-strength paper pulping rate height, the utilization rate height to waste paper has reduced waste, has reduced production cost; In addition, do not add any chemical agent in the technical process of the present invention, can not pollute, realized the purpose of environmental protection environment.
The specific embodiment
For the ease of those skilled in the art's understanding, the present invention is further illustrated below in conjunction with embodiment:
A kind of wet strength paper treatment technology, implementation step is: (1) adds hot water and wet-strength paper in pulper, and hot water content is 85～90% by weight percentage, wet-strength paper concentration is 10～15%, and the hot water temperature is 55-65 ℃, the size degradation time is 15～20 minutes, and wet-strength paper is carried out size degradation; (2) heavy metal class impurity is removed in purification; (3) the spiral thickener concentrates slurry, after concentrating by weight percentage slurry concentration be 28～32%, moisture is 68～72%; (4) spiral heater heating, control temperature make slurry further soften, moisten and rise between 90～110 ℃; (5) slurry enter heat dispersion machine further torn up after dilute, pull an oar fine slurry.Described pulper is that shell is equipped with electromagnet equipment, the hole diameter of sieve (perforated) plate is the pulper of 20～30mm, and heat dispersion machine is selected the strong big flute profile heat dispersion machine of the ability of tearing up for use.
Below be to indefiniteness embodiment of the present invention, concrete parameter can change according to actual conditions.
Embodiment one: the waste paper that will contain wet-strength paper is put in the pulper, the water that adds 60 ℃ again, by weight percentage, waste paper concentration is 11%, water content is 86%, 16 minutes size degradation time, pulper purified slurry after size degradation was finished, since pulper be electromagnet equipment is housed, the hole diameter of sieve (perforated) plate is the pulper of 30mm, effectively remove heavy metal class impurity, and, can realize not entered subsequent processing by sieve plate by a scrap of paper of size degradation pulping owing to adopt wide-aperture sieve plate, can not discharge, reduce waste with slag; Slurry concentrates through the spiral thickener then, making slurry concentration is 28%, moisture is 72%, heat through spiral heater again, temperature is heated to 95 ℃, make slurry further soften, moisten and rise, slurry is further torn up after the processing of diluting, pull an oar obtains can be made into the fine slurry of the high-quality fibrous raw material of producing craft paper through heat dispersion machine again.
