Description

Dry-process-treated waste paper pulping production line

Technical Field

The embodiment of the utility model provides a waste paper pulping technical field, concretely relates to waste paper pulping production line is handled to dry process.

Background

The waste paper is the main raw material of the current paper making, the contradiction between the shortage of the paper making raw material and the energy consumption can be relieved by the waste paper making, the sustainable development concept is also met, and the increasingly serious environmental pollution problem can be relieved. Compared with the direct use of the commercial pulp board, the cost can be effectively reduced by using the waste paper as the raw material for pulping.

At present, the waste paper treatment process mainly comprises a disintegration system (with the concentration of 3-5%), a screening system (with the concentration of 1.5-2%), a fiber grading sieve (with the concentration of 1.5-2%), a multi-disc concentrator (with the concentration of 8-12%) and a disc type heat dispersion system (with the concentration of 92-95%). The first step in deinking is the key step, and if the size is not ideal, deinking is not ideal. The result of the disintegration mainly affects the fiber dispersion of the waste paper, the stripping and redeposition of ink from the fibers, and the separation and re-binding of contaminants such as stickies from the fibers. Therefore, broke disintegration is the most critical step in a broke pulping system. It plays a crucial role in that waste paper is crushed into recycled pulp and ink is peeled off from the paper surface and can be properly separated from other impurities. The waste paper disintegrating process has mechanical action, chemical action and heat energy action. In addition, the disintegration time also plays an important role. These are all closely related to energy consumption. The mechanical action is mainly shown in the aspects of the consistency of the disintegrating pulp and the rotating speed of a rotor of the disintegrator, and the chemical action is mainly shown in the aspects of the pH value at the beginning of the disintegrating and the stripping of the printing ink; the thermal effect is mainly expressed in the aspect of the disintegration temperature.

At present, the waste paper is mainly pulped by a hydrapulper under certain pulping conditions. The process needs to consume a large amount of water and a disintegration aid to wet, permeate and disperse fibers, so that the cost is high and the energy consumption is high; the time for disintegration is long, the re-adhesion and re-deposition of ink or pigment on the fiber can be increased, and the quality of paper pulp is not good; the disintegrating aid is a chemical aid added into a pulping system to enable fibers to generate various effects such as wetting, permeation and dispersion to assist in waste paper disintegrating, and the chemical aid not only pollutes the environment, but also causes high energy consumption and serious water pollution.

Therefore, in the field of waste paper pulping technology, there is still a need for research and improvement on the dry process waste paper pulping production line, which is also a research focus and emphasis in the field of waste paper pulping technology at present, and is the starting point of the present invention.
