Abstract
The present invention relates to a technique using plant fiber raw material to prepare alkali hydrogen peroxide chemimechanical pulp. The technique comprises the processes of wood chips, washing, steaming, thermokalite pretreatment or hot water pretreatment, a double spiral pulping machine, a reaction bin, a disk grinder pulping, sedimentation removal, sieving purification, concentration and paper pulp. The pulping and bleaching technique of the technique comprises: a prepared H2O2 water solution with the concentration of 5 to 10% is added into an H2O2 storage tank; NaOH, NaSiO3 and water are prepared into mixed liquor with the concentration of 5 to 10%, and the mixed liquor is added into the other storage tank. Two measuring pumps are respectively used for quantitatively and continuously filling final mixing liquid medicine into the machine firstly through two pipelines merged into one pipeline and a medicine filling hole on the double spiral pulping machine; material carries out chemical reaction in a casing, and discharge alkaline liquor can soften the material. Because an extrusion fluffer and a dipping machine are replaced, the energy source is saved, and the occupation area is saved.
Description
One, technical field: the present invention relates to a kind of technology for preparing APMP with plant fiber material.
Two, background technology: conventional alkaline hydrogen peroxide mechanical feedback technological process mainly contains:
One section is pushed and infusion process: the wood chip-washing-decatize-extruder-macerator-reaction warehouse-high dense mill-middle pond-pressafiner-high dense mill-latent pond that disappears-screening purification-thickener-paper pulp (can be used for proportionaling collecting newsprint);
Two sections are pushed and infusion process: wood chip-washing-decatize-section extruder-section macerator-reaction warehouse-two section extruder-two section macerator-reaction warehouse-high dense mill-middle pond-pressafiner-high dense mill-latent pond-screening purification-thickener-paper pulp (can be used for paper kinds such as proportionaling collecting newsprint, cultural paper) disappears;
PRC method (continuing bleaching action behind the high consistency refining): section high dense mill-reaction warehouse-wood chip-washing-decatize-section extruder-section macerator-reaction warehouse-two section extruder-two section macerator-reaction warehouse-a section high dense mill-two disappears latent pond-screening purification-thickener---paper pulp (can be used for paper kinds such as proportionaling collecting newsprint, cultural paper).
Existing pulping process flow most critical be exactly the crowded stone roller effect of spiral shredder (extruder), it directly influences fibre bundle content in the whiteness of slurry and strength character and the slurry.Slurrying and bleaching are to finish by alkaline hydrogen peroxide solution, select to flood hop count, NaOH, H according to assortment and the desired intensity of slurry and whiteness
2O
2Consumption.In order to reach certain pulping intensity, the amount of sodium hydroxide during dipping is generally than higher.Single hop alkaline hydrogen peroxide dipping alkali charge is up to 5.5%, and alkali charge is generally 1%-2% when the paper pulp hydrogen peroxide bleaching.Because dipping is to carry out under normal pressure, the oxygen that hydrogen peroxide decomposes generates is dispersed in the atmosphere, does not form relevant pressure in macerator, and along with the raising of the basicity of solution, the decomposition rate of hydrogen peroxide also can increase greatly.
Three, summary of the invention: purpose of the present invention is exactly the problems referred to above that exist at prior art, and a kind of APMP technology of preparing of utilizing double helix fiberizer equipment to replace extruded segment and impregnation stage in the prior art is provided.
The present technique technological process comprises: wood chip, and---------------------it is latent to disappear, and---screening purifies---concentrating---paper pulp to the mill defibrination to reaction warehouse to one section double helix fiberizer to decatize for thermokalite or hot water preliminary treatment in washing.
The present technique technological process also comprises: wood chip, and---------------------------it is latent to disappear, and---screening purifies---concentrating---paper pulp to the mill defibrination to reaction warehouse to two sections double helix fiberizers to reaction warehouse to one section double helix fiberizer to decatize for thermokalite or hot water preliminary treatment in washing.
The pulping bleaching technology of present technique is: with the concentration that the prepares H at 5-10%
2O
2The aqueous solution adds H
2O
2In the basin; With NaOH, NaSiO
3Water is made into concentration 5-10% mixed liquor, adds in another basin.Remerging through two pipelines earlier with two measuring pumps respectively is a pipeline, dosing hole on the double helix fiberizer, quantitatively inject final admixing medical solutions in this machine continuously, make material in casing, produce chemical reaction, discharge alkali lye and can soften material, thereby in the defibrination process, reduce the generation of fibre debris and fibre bundle content, keep the length of fiber as far as possible, and improve the bond strength of fiber.Hydrogen peroxide plays discoloration to material simultaneously, finally makes the alkaline hydrogen peroxide machine slurry of high-whiteness high-strength.Owing to replaced squeezing extrusion machine and impregnator, saved the energy, saved floor space.
