Activated carbon regeneration system and regeneration method thereof

Abstract

According to the technical scheme, the activated carbon regeneration system is characterized by comprising a first reaction kettle, a first drying and filtering device, a second reaction kettle and a second drying and filtering device which are sequentially connected, and the first reaction kettle and the second reaction kettle are the same in structure; the first drying and filtering device and the second drying and filtering device are the same in structure and are used for filtering materials and drying solids obtained after filtering, and stirring devices are arranged in the first reaction kettle and the second reaction kettle; the feeding mechanism is arranged on the first reaction kettle and the second reaction kettle and is used for scattering powdery materials and adding the powdery materials to the stirring devices in the first reaction kettle and the second reaction kettle; the reaction kettle has the beneficial effects that mixing is uniform, the reaction efficiency is high, and powder is not prone to caking during feeding.

Description

technical field [0001] The invention relates to the technical field of activated carbon production, in particular to an activated carbon regeneration system and a regeneration method thereof. Background technique [0002] Activated carbon is a specially treated charcoal. Organic raw materials (husks, coal, wood, etc.) are heated in the absence of air to reduce non-carbon components (this process is called carbonization), and then react with gas, and the surface is Corrosion, resulting in a microporous structure (this process is called activation); in addition to carbon, activated carbon also contains two types of admixtures: one is chemically combined elements, mainly oxygen and hydrogen, these elements are due to It is completely carbonized and remains in the carbon, or during the activation process, the foreign non-carbon elements are chemically combined with the surface of the activated carbon; another type of admixture is ash, which is the inorganic part of the activated...

[0002] Activated carbon is a specially treated charcoal. Organic raw materials (husks, coal, wood, etc.) are heated in the absence of air to reduce non-carbon components (this process is called carbonization), and then react with gas, and the surface is Corrosion, resulting in a microporous structure (this process is called activation); in addition to carbon, activated carbon also contains two types of admixtures: one is chemically combined elements, mainly oxygen and hydrogen, these elements are due to It is completely carbonized and remains in the carbon, or during the activation process, the foreign non-carbon elements are chemically combined with the surface of the activated carbon; another type of admixture is ash, which is the inorganic part of the activated carbon, and the ash in the activated carbon is easy to cause secondary pollution , activated carbon is widely used in production and life due to its strong adsorption. Regenerated activated carbon is reactivated after the activated carbon with full adsorption is treated under certain conditions, and the regenerated activated carbon is produced to reactivate the fully adsorbed activated carbon; in the prior art , such as the patent with the patent authorization announcement number of CN108993458B, which is the same as the existing production process, the production is complicated, and the existing production equipment is not sufficient during the mixing reaction, the production efficiency is slow, and the waste powder is easy to form lumps when feeding.
