Description
Technical field
The utility model belongs to pulp technology for making paper, is specifically related to a kind of waste paper pulp-making, approach system.
Background technology
As everyone knows, China is a papermaking big country, and annual various paper and paperboard total output is more than 7,350 ten thousand tons, and for this year, the various fibre resources of needs will more than 7,000 ten thousand tons; But China is also the country of a forest reserves shortage, and Papermaking fibers resource is most deficient.For meeting papermaking demand, China needs the waste paper of import more than 2,000 ten thousand tons and the Original Pulp more than 8,000,000 tons year.But the raw materials for production of various wet strong waste paper are all precious bast fiber and superior in quality xylon usually, and these fibrous raw materials burn or landfill will be the greatest waste of resource.If this type of fibre resources can scientifically recycle; landfill can either be stopped or burn this type of resource pollution on the environment; new fibre resources can be opened up again; and then reduce China's paper industry to the dependence of primary slurry; reduce pulping bleaching to the consumption of the resource such as water, electricity; the forest reserves that protection China is few, thus reduce social cost.
The recovery and reuse of waste paper are Important Actions of developing a circular economy, building a conservation-minded society.Utilize waste paper as fibrous raw material in a large number, decrease the consumption of paper production to domestic forest tree resource, meet the principle of China's recycling economy " minimizing, recycling, resource " completely.Company's year reclaimed waste paper 400,000 tons, just can produce 320,000 tons of paper pulp, is equivalent to cut 170,000 trees greatly less, save the refuse landfill space of 12 ten thousand steres, use soda ash 100,000 tons less, reduce more than discharge of wastewater 9,600,000 side of papermaking, save papermaking energy resource consumption 9.6 ten thousand tons (mark coal).The more important thing is, the meaning that waste paper reclaims but is not only far away environmental protection and resources conservation.Along with the fast development of Chinas paper industry, international market paper pulp and waste paper price continuous rise, bring very large difficulty to China's papermaking enterprise.At present, the waste paper total amount of whole world available for export is about 2,500 ten thousand tons, China's waste paper importation amount accounted for its 1/3; More than 50% of the American waste paper total volume of exports sells to China.A few years from now on, China is still very large to waste paper demand, but waste paper resources is limited, once world's waste paper big bulge in price is difficult to bear to enterprise or world's accident affects the normal transport of waste paper, brings very serious consequence by Chinas paper industry.Therefore, improve the rate of recovery and the Appropriate application waste paper resources of domestic waste paper, not only of far-reaching significance to building a conservation-minded society, and the sound development to Chinas paper industry, also will play important effect to Chinas paper industry Industrial Security.
