Detailed Product Description: | Mixed waste paper deinking pulp process design transformation to find the the Xingtai Crystal Health Products Co., Ltd. Mixed waste paper deinking process design The process features: shorter than the other de-inking process, pulp, high whiteness, very low dust, high bleaching efficiency, chemicals with less. The process is simple, easy to upgrading of the old production line (generally required turning off multiple devices), low investment in equipment. Very mature of key equipment, easy to operate, virtually trouble-free, integrated power consumption is relatively low, long service life of equipment. Pulp brightness is adjustable between 80 to 95 degrees. Less fiber degradation, low pollutant generation, pulp and high yield. Efficient deinking water purification measures to effectively remove ink and anionic substances, most of the fine fiber and filler retained in the pulp, the closed loop system with water, add some water or paper machine white water. The wide adaptability of waste paper is not only effective in the removal of office waste ink, you can also allow a lot of waste newspaper and a small brown paper. Deinking line basic objectives: control, stripped of impurities on the fiber and ink particle size requirements and grading and fiber separation. Pulp ISO brightness 90% ± 2 Pulp dirt <20ppm Tons of pulp consumption of clean water (or water) <20m3 The purpose of the pulper: low temperature, neutral soft pulping process, so that waste paper to achieve 50% to 60% fibrosis, more complete spin-off books adhesive, plastic coated, staples and other impurities. Avoid a dispersed emulsion of the ink, to reduce the pollution of the fiber, reduce wastewater CODGr generation. Avoid fiber degradation, and improve slurry rate. Priority to the separation of the easy things first: in the thick screening and purification technology, separating the larger impurities. Squeeze in high concentration in the pulp waste, and reduce further pollution and bleaching drug consumption of pulp. Complete separation of the ink and fiber deinking chemical process: the use of reasonable, effective thermodynamic and shear the ink from the fibers to a suitable particle size stripped down (ink particle size is controllable). Take full advantage of the deinking process of high temperature and effective mixing completed save more than 25% of waste paper pulp bleaching (bleaching drugs). Further clear stickies: H <0.12mm slit sieve to remove coarse fiber bundles, long chemical fiber, plastic sheet and a larger particle size of the adhesive materials. Practice has proved that the production, screening the best equipment to remove stickies, and remove the ink a negligible role, do not try to use fine sieve to remove the ink. Non-contact printing ink detachment Toner ink and other non-pressure printing inks and other "hard ink" in the pulping waste a lot of power, can only make them into Adhesion fiber particles, due to their flat shape is difficult to be filtered, effective method of purification, flotation and washing to remove. The targeted removal of "hard-ink" in the pulping process after the production run is ideal. Purification can not be ignored The deslagging removed ink particles, particle size, hydrophilicity, density and other factors is difficult to remove by other devices, so pay special attention to the conditions of heavy Cleaner. "Hard ink is generally more dense than water, if the particle size can be appropriately Cleaner effectively remove. Flotation deinking: printing ink particle size, the type of deinking agent, flotation concentration, white water system and other factors, according to the actual conditions of the role of adjustments in order to give full play to the flotation. Add some kind of flotation aids, there are more prominent on the system water purification capacity can significantly improve the whiteness, but also can improve slurry rate. Washing deinking: wash can improve the whiteness of 8% to 12% (ISO). As long as the conditions are appropriate, water-based aniline ink particle washing method can be used very effectively to remove. Countercurrent washing to extract high concentrations of waste water, can reduce water consumption, reduce the load of the wastewater treatment. Pulp bleaching: bleaching reaction in high concentration, high pressure, high temperature conditions in the shortest possible time to reduce the degradation of fibers and other contaminants, not only to improve to get slurry rate and can reduce the secondary stickies. The whiteness of the pulp can be adjusted between 80 ~ 95 (ISO). |
