Abstract
The invention discloses a novel waste paper recycling method. The method comprises a shredding process, a deinking process, a removing process, a bleaching process and a papermaking process, wherein waster papers are shredded in the shredding process; the shredded paper is deinked by utilizing a deinking agent in the deinking process; printing ink particles in paper pulp are removed in the removing process; the paper pulp is bleached in the bleaching process; the paper pulp is used for making paper again through utilizing a papermaking technology in the papermaking process. The method is simple in operation process, and the waste paper is recycled, degraded and reused through adopting a waste paper recycling technology, so that energy-saving and environment-friendly purposes are achieved.
Description
Technical field
The invention belongs to pulp technology for making paper, relate in particular to the method that a kind of novel waste paper is recovered in utilization.
Background technology
In daily life, all can produce waste paper every day, to these waste paper, as not collecting utilization, will pollute environment, as collect and fully utilize, and just can turn waste into wealth, and becomes useful resource.
Be devoted to protect under the big atmosphere of environment in the whole world, a lot of waste paper recoverying and utilizing methods occurred, but become to produce the cost height, the technological process complexity is difficult to come into operation, and environment is caused secondary pollution.
Summary of the invention
In view of this, the objective of the invention is to, provide a kind of novel waste paper recycling method to solve the problem that above-mentioned prior art exists aspect the waste paper recycling.
Technical scheme of the present invention is that a kind of novel waste paper recycling method comprises pulverizing process, deinking operation, removes operation, bleaching process, manufacturing process; Described pulverizing process carries out size degradation with waste paper, described deinking operation is to utilize deinking agent that shredded paper is carried out deinking to handle, described removal operation is that the ink particle in the paper pulp is removed, described bleaching process is that paper pulp is bleached, and described manufacturing process manufactures paper by paper technology again with paper pulp.It is characterized in that, said method comprising the steps of;
Steps A: pulverizing process carries out size degradation with waste paper.
Step B: the deinking operation is to utilize deinking agent that shredded paper is carried out deinking to handle, and makes ink particle and paper fiber separation.
Step C: removing operation is that the ink particle in the paper pulp is removed, and prevents that the bulky grain particle is in deposition.
Step D: bleaching process is that paper pulp is bleached, and the whiteness of paper pulp is improved, and removes ink particles in the paper pulp again.
Step e: manufacturing process manufactures paper by paper technology again with paper pulp.
Described pulverizing process carries out size degradation with waste paper.
Described deinking operation is used a kind of surfactant and composite deinking agent that forms of organic solvent of containing, can be effectively with ink particle and paper fiber separation.
Described removal operation adds ink absorbent, and ink particle and the sicker activity by self is attached together it, reduces its viscosity.
Described bleaching process adds chlorine dioxide and bleaches, and its advantage is the bleaching efficiency height, and whiteness height and good stability reduce the water dustiness, reduce the paper grade (stock) water yield.
Described manufacturing process manufactures paper by paper technology again with paper pulp.
Beneficial effect of the present invention: the operating process that the present invention adopts is simple, by waste paper recycling technology, is waste paper recovery, degraded, recycling, reaches the purpose of energy-conserving and environment-protective.
