Description
Technical field:
The present invention relates to a kind of pulping process of chemi-mechanical pulp, relate in particular to a kind of employing oil palm EFB high concentration extruding displacement method Alkaline Peroxide Mechanical Pulp (CEMP) pulping process.
Background technology:
External pulping technique is mainly alkaline process, ammonium sulfite, neutral inferior sodium method and half chemical method etc. at present.The pulping raw material major part is timber and a small amount of straw pulp.These several traditional pulping technology for paper-making have a large amount of black liquor to discharge in digestion process, caused the serious environmental pollution, and present transformation to pulping technology for paper-making, the processing that all centers on black liquor is transformed, therefore, need to be equipped with chemical recovery system and sewage disposal device, equipment investment is big, bring investment burden to enterprise, and increased production cost.Utilize EFB slurrying to be in the starting stage in China, big as amount of investment, general enterprise is difficult to bear, and certain risk is arranged.How to utilize the annual 3000 ten thousand tons of EFB discarded object pulping and paper-makings of China, the green environment free pulping method of walking a small investment, instant effect should be first-selected.
At present, the external existing pulp-making method of producing the APMP slurry is one section or two sections squeezing extrusion pulp-making methods. the technological process of two sections squeezing extrusion methods, mainly wash by wood chip, decatize, 1# single-screw squeezing extrusion machine, 1# macerator (being added with chemical liquid), the 1# reaction warehouse, 2# single-screw squeezing extrusion machine, 2# macerator (being added with chemical liquid), the 2# reaction warehouse, one section high dense mill, towards rare pond, two sections high dense mills, latent pond disappears, screening purifies, operation such as thickener and machine chest is formed, the pulping chemistry medicine is formed, comprise: NaOH (sodium hydroxid), H2O2 (hydrogen peroxide) etc.Slurrying and bleaching are finished by alkaline hydrogen peroxide solution.Tearing, flooding of wood chip is to finish in single-screw squeezing extrusion machine and macerator.Loosening apparatus is dredged in the single-screw extruding, and compression ratio (volume change) carries out the extruding and tearing processing to wood chip in its machine by adjusting, and makes wood chip be shredded into fine debris along its grain direction, makes it suck pulp liquor fully in macerator.Since wood chip tear and dipping effect will directly influence the slurry chemical extent of reaction in the reaction warehouse and follow-up defibrination quality, therefore, single-screw squeezing extrusion machine is the crucial pulping equipment of system APMP slurry in the technological process.Yet, existing APMP slurry pulping process flow does not reach the desirable effect that requires because of there is the extruding and tearing processing because of fibrous raw material in the single-screw squeezing extrusion machine of selecting for use, and the pulp liquor impregnation process that causes fibrous raw material does not thus reach the defective of desired effect, simultaneously macerator exists because of often bringing pulp liquor into reaction warehouse, causes slurry concentration instability in the reaction warehouse thus and influences the shortcoming of follow-up defibrination section quality.
Summary of the invention:
The purpose of this invention is to provide a kind of employing oil palm EFB high concentration extruding displacement method chemi-mechanical pulp (CEMP) new pulping process, this technology is ground by having efficiently once to finish to squeeze, tear, the 1# double helix extruding kneader and the 2# double helix squeezing mill pulp grinder of soup dipping and high dense mixed process effect, squeezing extrusion and the impregnation technology finished by 1# single-screw squeezing extrusion machine and 1# macerator and 2# single-screw squeezing extrusion machine and 2# macerator in the prior art processes flow process are united two into one, make monkey grass formed high extrusion in double helix extruding kneader one machine grind tear zone, low pressure soup Dilvar zone and high pressure soup mix the crowded tear zone that grinds and must tear in fully squeezing to grind, impregnation process, tear thereby improve, dipping effect, and under high pressure force monkey grass to mix with the pulping bleaching soup, improve the defibrination quality, and then solve the shortcoming that exists in the above-mentioned background technology.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: pulping process flow, wash by monofilament, decatize, hot water or alkaline Pretreatment, 1# double helix extruding kneader, the 1# reaction warehouse, 2# double helix squeezing mill pulp grinder, the 2# reaction tube, one section high dense mill, dense mill in two sections, the latent pond that disappears, screening purifies, and operations such as thickener and machine chest are formed, select 1# single-screw squeezing extrusion machine and 1# macerator and 2# single-screw squeezing extrusion machine and 2# macerator in 1# double helix extruding kneader and the 2# double helix squeezing mill pulp grinder replacement prior art flow process in this technological process for use, squeezing extrusion and these two technologies of dipping that reason single-screw squeezing extrusion machine and macerator are finished unite two into one, and are finished by double helix extruding kneader, and the pulping bleaching soup flows into respectively in 1# double helix extruding kneader and the 2# double helix squeezing mill pulp grinder.
The composition of described pulping bleaching soup comprises: NaOH, H2O2, Na3SiO3, (sodium silicate), DTPA chemicalss such as (rare triamine five acetic acid of diethyl).

Adopt the pulping process of this specific embodiment, prepared pulp quality index:
Beating degree: 35-45SR; Tear long 4Km; 75 ° of SR of tear index 3.8mN whiteness
From above-mentioned pulping process as can be known:
1. because this specific embodiment pulping process adopts hot water or alkaline Pretreatment to make it softening to air-dry monofilament, therefore significantly improve the final pulp quality of extruding and tearing effect of postorder section; Because having once to finish efficiently to squeeze to grind, tears double helix extruding kneader, the effect of dipping and high dense each technical process of mixing, and therefore, it unites two into one squeezing extrusion and the impregnation technology in the prior art slurrying flow process, is finished by double helix squeezing extrusion machine.This has not only simplified pulping process flow, and the crowded stone roller of monofilament torn and maceration has and show to annotate effect, but and the crowded stone roller tear(ing) strength of flexible modulation fibre material, and can realize the high dense mixing circulation displacement of fibre material and pulping bleaching soup, because quantitatively dosing in double helix extruding kneader, therefore, slurry steady concentration in reaction tube and the fiberizer be can guarantee, thereby slurrying and bleaching effect improved:
2., the dosing of this technology slurrying overall process multiple spot, increase palm slurry quality insurance coefficient, guaranteed that the defibrination quality is calm dangerous.
3., compared with prior art, it is about about 45% that the equipment investment expense of this specific embodiment reduces, and slurrying is energy-conservation about 20%, therefore, has reduced the slurrying production cost.
4., because this specific embodiment pulping process adopts high dense processing at monkey grass character, thereby reduced slurrying water consumption and wastewater treatment load, have the environmental protection meaning.
5., the whole technical process of this specific embodiment, can make ETB pulp quality index reach 75 ° of ISO of whiteness, fracture length 4KM, single-screw squeezing extrusion machine handle EFB paper pulp and then do not reach this index, particularly whiteness and only can reach 58 ° of ISO.
This specific embodiment EFB new pulping process also adapts to raw material production CEMP paper pulp such as leaf woods such as poplar, birch, shredded coconut meat and bagasse.
