Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon decolorization, in particular to an activated carbon decolorization reaction device. Background Art

[0002] Activated carbon for decolorization is made of high-quality sawdust and other raw materials using the zinc chloride method. It has a developed mesoporous structure, large adsorption capacity, and rapid filtration characteristics. It is often used in the decolorization, purification, deodorization, and impurity removal of high-pigment solutions such as various amino acid industries, refined sugar decolorization, MSG industry, glucose industry, starch sugar industry, chemical additives, dyeing intermediates, food additives, and pharmaceutical preparations. When general products are decolorized with activated carbon, the product to be decolorized is dissolved in a solvent. After the solid product is completely dissolved, it is poured into a decolorization container filled with activated carbon. The solvent flows through the activated carbon, and the strong adsorption capacity of the activated carbon is used to achieve the purpose of decolorization and impurity removal.

[0003] In the prior art, the activated carbon contained in the reaction device is always in a static state during the decolorization process. The solvent enters the device from the top and flows out from the bottom. Generally, after the activated carbon at the top reaches a saturated state, the activated carbon at the bottom still has adsorption capacity. At this time, the decolorization efficiency of the solvent entering the device is low. After flowing through the container, it may still contain some pigments that have not been completely adsorbed. The staff needs to periodically pause the decolorization reaction of the device and replace the activated carbon, which reduces the working efficiency. Utility Model Content
