Embodiment Construction
[0031] Below in conjunction with accompanying drawing 1 to 3 the embodiment of the present invention is described further:
[0032] Shown in Fig. 1 overall technological process of the present invention, wherein cut raw material and dehydration drying can adopt traditional prior art technology, do not go into details here; Explosion and cooking pulping are two core processes of the present invention.
[0033] figure 2 It shows that the detonation process of the sub-process of the present invention is one of the core processes of the present invention; firstly, the raw material is heated to more than 160°C-180°C, and then sent into the sealed cavity to continue heating to 180°C-200°C. The temperature and pressure of the raw material just entering the tower are lower than those in the tower. The gasified chemical components in the raw material will not escape from the raw material. The water content of the raw material is less than 15%, the cells and structural "components" ar...

The invention discloses a method for manufacturing plant fiber pulp. The method comprises steps of material cutting, dewatering and drying and steam-boiling and pulping; materials after the dewatering and the drying undergo the explosion treatment, which explodes materials into fibers; the steam-boiling and the pulping is that exploded dry fibers and hydrogen peroxide solution are put in a sealing container for steam-boiling and pulping; the explosion process is as follows: materials are preheated up to the temperature of between 160 to 180 DEG C and put in a closed cavity and heated up to the temperature of between 180 to 200 DEG C, which makes the inside pressure and the outside pressure of the internal fiber structure of materials balanced, and the steam explosion is generated after the instant release of materials, and the materials are exploded into fibers; the steam-boiling and the pulping process is as follows: materials are heated up to the temperature of between 60 to 80 DEG C, and put in a closed space and heated up to the temperature of between 95 to 105 DEG C by steams with the temperature of between 110 to 120 DEG C, which separates material fibers to be pulp liquid. Due to the steam explosion, all oily and fatty substances are vaporized and volatilized, so that organic sugar substances can be quickly dissolved into water; due to the addition of hydrogen dioxide solution in the steam-boiling and the pulping, no waste is generated, thereby effectively eliminating energy waste and protecting environment.
Description
technical field [0001] The invention relates to the technical field of papermaking, in particular to a method and flow for producing plant fiber pulp. Background technique [0002] The plant fiber pulp currently produced is mainly used for the production of paper products. The pulping methods mainly include: chemical pulping, semi-chemical pulping, chemical mechanical pulping, and mechanical pulping are used in operation. [0003] Chemical pulping uses fiber plants to make raw materials. Chemicals such as acids, alkalis and salts are dissolved in water to form a cooking liquid. After high-temperature and high-pressure cooking, strong chemical energy is generated, which breaks the chains and bonds of most of the chemical composition structures wrapped in the fiber filaments in the raw materials and dissolves them into the water. The fiber filaments are also dispersed in the water to form a mixed slurry: pulp. The time for cooking pulp is from tens of minutes to several hou...
