Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon solid waste treatment, in particular to an activated carbon solid waste dust treatment device. Background Art

[0002] Activated carbon is a specially treated carbon, mainly used as a solid adsorbent in the chemical, pharmaceutical, and environmental fields, and is used to adsorb substances with high boiling points and critical temperatures and organic substances with large molecular weights. Activated carbon powder is used in the decolorization, alcohol extraction, and recrystallization processes in the production of glycyrrhizic acid due to its large adsorption capacity and rapid filtration.

[0003] At present, activated carbon powder is light in weight and easily dissipates into the surrounding air during use, which seriously endangers the health of operators in positions where activated carbon dust is applied, and also affects the operating environment of each position. For activated carbon dust, the conventional treatment method is to absorb it in the exhaust system. Although this method can achieve the treatment of activated carbon powder, the absorption liquid that absorbs the activated carbon dust needs to be filtered during the post-treatment process. There is still a risk of dissipation after filtration, and once the amount of activated carbon dust increases, the frequency of replacement of the absorption liquid increases.

[0004] In view of this, it is necessary to provide a new activated carbon solid waste dust treatment device. Utility Model Content
