Problems solved by technology

In the process of newsprint production, a large amount of papermaking sludge will be produced, and the papermaking sludge contains more crude fibers. In the prior art, most of the treatment methods for this kind of papermaking sludge are incineration or landfill, resulting in waste of resources and environmental pollution. Pollution is contrary to the development principle of "reduction, reuse, and recycling" in the national "Paper Industry "Twelfth Five-Year Plan";
[0003] In addition, the bobbin base paper in the prior art is made of waste paper pulp or virgin pulp, the cost of raw materials is high, waste paper resources are not saved, and a large amount of clean water is required in the production process, and the waste water and waste water generated in the production process need to be treated. waste residues, resulting in waste of resources and energy and environmental pollution

Embodiment Construction

[0014] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 Shown, the method that utilizes newsprint papermaking sludge of the present invention to produce environment-friendly regenerated bobbin base paper may further comprise the steps:

[0016] 1) Treatment of newsprint papermaking sludge: Newsprint papermaking sludge is sent to a pre-thickener, and the newsprint papermaking sludge is concentrated to a predetermined concentration through the pre-thickener, and the concentrated newsprint papermaking sludge is sent to a high-concentration slag remover for deslagging. The newsprint papermaking sludge obtained after slag enters the coarse screen for further screening, and the screened newsprint papermaking sludge enters the storage tank; among them, the final control of the process parameters is as follows: the pulp concentration of the high-concentration deslaggi...

Abstract

The invention discloses a method for producing environment-friendly regenerated bobbin body paper by using paper mill sludge of newsprint, relating to the field of recycle of paper mill sludge of newsprint. According to the method provided by the invention, the environment-friendly regenerated bobbin body paper is prepared by the following steps: mixing treated paper mill sludge of newsprint with treated OCC pulp in a certain proportion; and manufacturing paper with pulp by white water in a newsprint papermaking process. According to the method provided by the invention, the environment-friendly regenerated bobbin body paper is produced by using paper mill sludge produced in the production process of newsprint, so that the production cost is lowered, the waste paper resources are saved, the water resources are recycled, and the environmental pollution is avoided.

Description

[technical field] [0001] The invention relates to the field of recycling and utilization of newsprint papermaking sludge, in particular to a method for producing environmentally friendly regenerated bobbin base paper by using newsprint papermaking sludge. [Background technique] [0002] Newsprint, also known as white paper, is the main paper used for newspapers and books. In the world, newsprint is the most used. In the process of newsprint production, a large amount of papermaking sludge will be produced, and the papermaking sludge contains more crude fibers. In the prior art, most of the treatment methods for this kind of papermaking sludge are incineration or landfill, resulting in waste of resources and environmental pollution. Pollution is contrary to the development principle of "reduction, reuse, and recycling" in the national "Paper Industry "Twelfth Five-Year Plan"; [0003] In addition, the bobbin base paper in the prior art is made of waste paper pulp or virgin p...
