Description

Technical Field

[0001] The invention relates to the technical field of regenerated zinc chloride decolorization, in particular to a regenerated zinc chloride decolorization device for vulcanized fiber and a production process thereof. Background Art

[0002] Zinc chloride is one of the main raw and auxiliary materials for the production of vulcanized fiber paper. About 8% of zinc chloride raw materials are consumed for each ton of vulcanized fiber paper produced. In the original process, the used zinc chloride raw materials are concentrated and recovered through the zinc chloride recovery section, and then repeatedly filtered by a filter press to remove impurities in the recovered zinc chloride liquid. However, there are still many fine fibers that cannot be removed, and the recovered zinc chloride liquid has a low density and cannot be directly put into production again. It is necessary to use steam high-temperature concentration treatment in a ceramic reactor to increase the density to about 1.950, and then after blending, it can be put into production. In the concentration stage, due to high-temperature treatment, the fine fibers and other impurities remaining in the zinc chloride liquid will be carbonized, and the originally transparent zinc chloride liquid will be darker in color and become soy sauce color, which cannot be used in the production of lighter-colored products. Therefore, the product specifications and categories are limited, which has a great impact on the company's sustainable development. To solve this problem, we have innovatively designed a regenerated zinc chloride decolorization equipment and production process for vulcanized fiber, which can completely solve this problem.
