Abstract
The invention belongs to environmental technology fields, more particularly to a kind of papermaking slurry fiber separation reuse method, the following steps are included: 1) slurry is dried, 2) pulverization process is carried out to the waste residue after drying, stirring crushing rolls crushing, and 3) waste residue after crushing is screened with impeller separator or sieve, isolate fibre blend, 4) fibre blend successively cleaned, filtered, dried, obtain fiber.The present invention both ensure that the cleaning of paper pulp, in turn ensure stable operation and the quality of finished paper of paper machine, and after fiber recovery, fibre loss greatly reduces, and papermaking cost decreases.
Description
Technical field
The invention belongs to environmental technology fields, and in particular to a kind of papermaking slurry fiber separation reuse method.
Background technique
Reclaimed waste paper fiber is one of main fiber source of paper industry, and external energy conservation and environmental protection policy and theory are more
It is advanced, for example, European Union's paper industry be dedicated to always recovery technology improvement, recycled fiber utilization rate has reached 66% within 2010,
Belong to leading position in the world.However domestic separating and recovering technology is started late, and is still restricted.
Using waste paper as paper pulp raw material, boxboard is produced, has and reduces pollution, the energy is saved, reduces investment outlay, reduce cost,
Mitigate to multinomial benefits such as disposable fibrous raw material dependences.But it since waste and old boxboard is many kinds of, varies in color, and containing big
Measure non-fiber impurity, such as metallic, stone, sand, plastics, adhesive tape, rag, hot-melt object, pitch etc..Therefore to waste paper
Size degradation and roughing cause very burden, need to carry out waste paper multistage multistage processing.
For existing issue, applicant devises a kind of papermaking slurry fiber separation reuse method.
Summary of the invention
In order to make up for the deficiencies of the prior art, the present invention provides a kind of technical side of papermaking slurry fiber separation reuse method
Case.
A kind of papermaking slurry fiber separation reuse method, it is characterised in that the following steps are included:
1) slurry is dried；
2) pulverization process is carried out to the waste residue after drying；Stirring crushes or rolls crushing；
3) waste residue after crushing is screened with impeller separator or sieve, isolates fibre blend；
4) fibre blend successively cleaned, filtered, dried, obtain fiber.
A kind of papermaking slurry fiber separation reuse method, it is characterised in that in step 1) by way of sunning pair
Slurry is dried.
A kind of papermaking slurry fiber separation reuse method, it is characterised in that by dryer to slurry in step 1)
It is dried.
A kind of papermaking slurry fiber separation reuse method, it is characterised in that in step 2 with blender to waste residue into
Row stirring crushes.
A kind of papermaking slurry fiber separation reuse method, it is characterised in that waste residue is carried out with pressure roller in step 2
Roll crushing.
The present invention both ensure that the cleaning of paper pulp, stable operation and the quality of finished paper of paper machine be in turn ensured, by fiber recovery
Afterwards, fibre loss greatly reduces, and papermaking cost decreases.
Specific embodiment
Below with reference to embodiment, the invention will be further described.
Embodiment 1
A kind of papermaking slurry fiber separation reuse method, comprising the following steps:
1) slurry is dried by way of sunning；
2) waste residue after drying is stirred, makes its crushing；
3) waste residue after crushing is screened with impeller separator, isolates fibre blend；
4) fibre blend successively cleaned, filtered, dried, obtain the fiber that can be recycled.
In embodiment 1, impeller separator is conventional vane type cyclone separator.
Embodiment 2
A kind of papermaking slurry fiber separation reuse method, comprising the following steps:
1) slurry is dried by dryer；
2) it is rolled with waste residue of the pressure roller after dry, makes its crushing；
3) waste residue after crushing is screened with sieve, isolates fibre blend；
4) fibre blend successively cleaned, filtered, dried, obtain the fiber that can be recycled.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
