Description
Technical field
The present invention relates to paper pulp waste process field, and in particular to a kind of that the dilution made is reclaimed using spent pulping liquor
Liquid.
Background technology
Paper industry environmental pollution is heavier, and in paper-making process, the lignin in plant is at high temperature by chemistry system
Various processes, its structure such as slurry are changed, and net macromolecular is degraded, and has partial lignin condensation product to be formed, and is in
Fragment dissolution of different sizes, while the main component for also having hemicellulose etc., turning into pulping waste liquor dissolved.
Paper pulp waste containing a large amount of lignin is seriously polluted, very harmful, it is necessary to carries out Synthetic to paper pulp waste
Reason, and the lignin focused in Recycling of waste liquid administered, and efficiently utilized using lignin as a kind of resource.Typically
It is the addition chromium class catalyst into paper pulp waste, chromium lignin sulfonate, the existing drop dehydration of chromium lignin sulfonate can be made
Effect, there is diluting effect again, while also there is the characteristics of salt resistance, high temperature resistance, good compatibility, be a kind of salt resistance, anticalcium and temperature resistance
The strong diluent of ability, is widely used in fresh water, seawater and saturated salt-water mud, various calcium treated mud and ultradeep well mud,
With effectively stabilizing borehole and make mud viscosity reduction, the drop effect of cutting.
But the hexavalent chromium in chromium class catalyst has severe toxicity, is easily absorbed after human contact, has carcinogenic danger, to ring
There is lasting danger in border, therefore the usage amount of the diluent of chromium lignin sulfonate is reduced year by year.
The content of the invention
Present invention solves the problem in that providing a kind of dilution for reclaiming and making using spent pulping liquor, main component is wood
Mahogany sulfonate, human body and environment will not be damaged without toxicity, during use.
In order to solve the above-mentioned technical problem, the technical scheme is that：
It is a kind of that the dilution made is reclaimed using spent pulping liquor, it is made up of following weight percent composition：
Lignosulfonates：65%~80%.
Quan Tie：2%~8%.
Calcium sulfate：1%≤3%.
Surplus：Moisture.
Preferably, the percentage by weight of the lignosulfonates is 75%~80%.
Preferably, the heavy percentage of the full iron is 2%~5%.
Preferably, the diluent is prepared by following methods.
Sulfuric acid, ferrous sulfate and hydrogen peroxide are added to the water mixing, prepare displacer.
The displacer is added in adhesive, a defective material is obtained after reaction, described adhesive is dense for paper pulp waste
Contracting liquid.
Potassium permanganate is mixed with water, prepares liquor potassic permanganate；
The liquor potassic permanganate is mixed with a defective material, secondary material is obtained after reaction.
The pH value of the secondary material is adjusted to 2.5~3.0.
The diluent main component provided by the invention prepared by paper pulp waste is lignosulfonates, and molecular weight is high,
The recycling of resource is realized, when the diluent is used for drilling well, using effect is notable, while also has high temperature resistant, nontoxic, nothing
The characteristics such as burn into compatibility is strong, it is safe to use without toxicity, human body and environment are safe from harm.
Embodiment
In order to further appreciate that the present invention, the preferred embodiment of the invention is described with reference to embodiment, still
It should be appreciated that these descriptions are simply further explanation the features and advantages of the present invention, rather than to the claims in the present invention
Limitation.
The present invention is handled paper pulp waste, without using chromium class catalyst in processing procedure, is prepared with wooden
Plain sulfonate is the not chromyl diluent of main component.The diluent that this is prepared by paper pulp waste is by following weight hundred
Divide and formed than composition：Lignosulfonates：65%~80%；Quan Tie：2%~8%；Calcium sulfate：1%≤3%；Surplus：Moisture.
Preferably, the percentage by weight of lignosulfonates is 75%~80%, the percentage by weight of full iron is 2%~5%.
Diluent provided by the invention is to be prepared by following methods by paper pulp waste：
It is standby first to prepare displacer, is first added to the water sulfuric acid during preparation, then adds ferrous sulfate, then to sulfuric acid and sulfuric acid
Hydrogen peroxide is added in ferrous mixed liquor, when adding hydrogen peroxide, is uniformly pressed hydrogen peroxide with 0.1Mpa~0.3Mpa pressure
Enter in mixed liquor, be then stirred.
For convenience of handling paper pulp waste, floor space is reduced, paper pulp waste is concentrated, pulping gives up
The concentrate of liquid is referred to as adhesive.The displacer prepared is added in adhesive again and reacted.The body of the displacer of addition
Product is preferably calculated according to the proportion of adhesive, and calculation formula is volume × adhesive of volume=adhesive of displacer
The mass percent concentration of full iron in × 4.1/ displacer of giving money as a gift of proportion × adhesive, wherein adhesive are given money as a gift as papermaking
Pulp waste concentration composite adhesives is given money as a gift, and is the weight of adhesive and the ratio of paper pulp waste weight.Calculated of course for convenient,
The proportion of adhesive can also be adjusted to the value that can be easy to calculate with water in advance,
After displacer quantitative after calculating is added into adhesive, the feed liquid of mixing is heated to 80 DEG C~85 DEG C, and be incubated 15min
~25min, obtain a defective material.
The preparation liquor potassic permanganate by potassium permanganate and water is also needed to, is calculated according to the proportion of obtained defective material
The quality of required potassium permanganate, calculation formula are proportion × bonding of volume × adhesive of quality=adhesive of potassium permanganate
Agent gives money as a gift × 0.060345, and volume=potassium permanganate of required water adds quality/0.15- potassium permanganate and adds quality.Prepare
When, water is first heated to 40 DEG C~60 DEG C, potassium permanganate is added according still further to the amount of calculating, potassium permanganate is then warming up to 80 DEG C
~85 DEG C, it is sufficiently stirred.
The liquor potassic permanganate of preparation is added in a foregoing obtained defective material and reacted, if according to the public affairs provided
Formula prepares liquor potassic permanganate, then adds whole liquor potassic permanganates in one defective material.During addition, 0.2Mpa~
Liquor potassic permanganate is uniformly pressed into a defective material under 0.4Mpa pressure, the press-in time is 25min~35min, is again heated to
80 DEG C~85 DEG C, and be incubated 15min~25min, obtain secondary material, the pH value control of secondary material can be used 2.5~3.0
NaOH is adjusted.The diluent that main component is lignosulfonates is thus obtained, can be made finally by spray drying
Into dry powder finished product.
