Description
Technical field
The present invention relates to field of Environment Protection, particularly a kind of wastepaper reclaiming method.
Background technology
Relevant investigation shows, office copy waste paper utilization rate is low, and the rate of throwing aside is about 95%.Office copy paper quilt
It is referred to as " noble " in paper, but in terms of huge profit, is nothing like other stationery.So high-quality paper in the office
The problem being far above in terms of environment out in the cold, that bring.To this end, We conducted wastepaper regeneration one
The experimentation of gasifying device.By analyzing the utilization rate of office copy paper on market and discarded rate, with common big
As a example by small-sized duplicating society in, within one week, it is about because of the waste paper quality of the subjective and objective problem generations such as reprography
6kg, and owing to producing waste paper place dispersion (such as each office scattered, duplicate society etc.) and without substantially rule
Rule, so system recovery operation difficulty is high.According to estimates, regenerated papermaking relatively timber papermaking can using water wisely 50%,
Save energy 60-70%, reduce the pollution 60-70% to air.National Development and Reform Committee proposes " the ten of papermaking industry
First Five-Year Plan " planning, it is desirable to waste paper utilization ratio brings up to 48% in 2010,2015 to 55%, the most domestic
Waste paper utilization ratio to reach 43%.So in order to reduce cost and reduce pollution, utilizing regenerated papermaking is to make
The developing direction of paper industry.The advantage of the waste paper regenerated integrated apparatus of office copy is volume relatively legacy equipment body
Long-pending little, easy to use, it is simple to operation, waste paper 100% reclaims.Discarded paper in the office enters machine from paper feed port
Device, by internal slurrying part, enzyme excusing from death ripple coordinates deinking system, and ozone hydrogen peroxide green is floated
White system, has children outside the state plan ripple vibrational system, and dress glue laminated is sanctioned after the flow process such as cutting, delivery outlet export brand-new doing
Public paper.The field that the paper usings such as this equipment is applicable to school, enterprise are concentrated.
China is the consumption big country of paper, but the forest reserves lack, and afforestation rate only 20.36% is far below
Developed country's level, the various ecological environment problems therefore caused with timber for main material production paper are not allowed
Ignore；The starting point of China's tradition Paper Industry Development is low, highly energy-consuming, maximum discharge, high pollution, poor efficiency,
Mostly use the heavy mechanical equipment of non-green environmental protection, be suitable only for producing in enormous quantities on a large scale；It is referred to as in paper
" noble " office copy paper, in terms of huge profit, be but nothing like other stationery.Relevant investigation shows,
The utilization rate of China's office copy waste paper is the lowest, and the probability directly thrown aside is about 95%, such high-quality
Paper abandoned as carried out, the problem being far above in terms of environment brought.
Japanology goes out expensive, and build is relatively big, and the wastepaper that energy consumption is higher utilizes machine, universal journey
Spend the highest, the blue light dry paper deinking device etc. manufactured such as " Aries ", the employing specialty inks of manufacture toilet paper,
There is no the small-sized integrated equipment that office copy waste paper is reproduced into paper in the office；
Other European countries such as the U.S., put into effect the laws and regulations that reply waste paper reclaims mutually, implement waste paper strict
Classification, its standard be up to more than 50 kind, for all kinds of paper products, take to recycle efficiently means, waste paper
Recovery utilization rate has reached about 93%, temporarily without without relevant small-sized machine invention.
Summary of the invention
The invention aims to provide a kind of wastepaper reclaiming method.
For reaching above-mentioned purpose, the present invention implements according to techniques below scheme:
A kind of wastepaper reclaiming method, comprises the steps:
1) take a certain amount of wastepaper in extractor, heat in 60 DEG C of constant temperature water baths, and add solvent
Being stripped, until extracting in sample after residual solvent evaporation, regulation concentration of slurry, to 8%, adds blender
In carry out the size degradation of waste paper, beating time is 45min；
2) after broken paper pulp in add that SKHZYE-DPE91 enzyme carries out before ultrasound deinking pre-
Process；
3) pretreated paper pulp is placed in ultrasonic treatment time 10min in ultrasonic cleaner, ultrasound wave
It is 40 DEG C that treatment temperature controls, and ultrasonic Treatment power is 300W, and ultrasonic Treatment frequency is 40kHz,
The concentration making paper pulp after process reaches 0.5%；
4) pulp density after deinking is adjusted to 10%-12%, PH and reaches 6, and temperature reaches about 55 DEG C;
5) again adding the SKHZYE-DPE91 enzyme being equipped with, the response time is 20min;
6) after cellulase treatment, paper pulp is acidity, and PH is 5-7, and temperature is 35 DEG C, now starts smelly
Oxygen Generator, produces ozone and bleaches paper pulp；
7) PH of paper pulp is adjusted to 10, adds PH stabilizer Na2SiO3, add appropriate hydrogen peroxide
Reagent, now, heightens temperature and reaches 90 DEG C, make the further bleached pulp of hydrogen peroxide；
8) paper pulp after bleaching forms wet web by Internet device；
9) press section of wet web entrance pressure boot-shaped carries out dehydration forming, makes wet web obtain preliminarily dried；
10) wet web after squeezing enters drying cylinder and dries, and clipped obtains finished paper.
As the further preferred scheme of the present invention, described step 3) ultrasonic cleaner adds a small amount of silicic acid
Sodium, sodium hydroxide and hydrogen peroxide.
Compared with prior art, the present invention uses the preconditioning technique of enzyme, breaks through tradition papermaking to chemistry
The dependence of test product；Use the bleaching technology that tractable hydrogen peroxide ozone mixes, pollution-free, green ring
Protect, reduce the difficulty that waste water processes；Improve the utilization rate of office copy waste paper and reduce paper in the office one-tenth
This, improve the waste paper recovery utilization rate of China, using water wisely and the energy, protect environment, simultaneously can be by each
Individual step process apparatus integration, automatization, it is simple to promote the use of.
