Abstract

The invention belongs to the technical field of activated carbon manufacturing and relates to a regeneration system and preparation method for waste activated carbon, especially to a regeneration system and regeneration method for waste activated carbon. The regeneration system for waste activated carbon comprises a waste activated carbon treatment unit, a mixing and granulating unit, a drying andcarbonizing unit and a finished product cooling unit which are mounted in sequence, wherein the waste activated carbon treatment unit is used for introducing waste activated carbon and screening, mixing, neutralizing and washing the waste activated carbon; an adhesive is added into a washed secondary raw material through the mixing and granulating unit, and extrusion is conducted to form semi-finished particles, and if a fed material is granular activated carbon, treatment via the mixing and granulating unit is not needed; the particles are subjected to drying, carbonizing and activating through the drying and carbonizing unit so as to form a high-temperature finished product; and the high-temperature finished product is cooled by the finished product cooling unit to form a finished product.

Description

technical field [0001] The invention belongs to the technical field of activated carbon production, and relates to a device and a preparation method for activated carbon regeneration treatment, in particular to a system and a regeneration method for the regeneration of waste activated carbon. Background technique [0002] Activated carbon is made of high-quality sawdust, coconut shell and coal as raw materials, and is refined through a series of production processes. The internal microporous structure of activated carbon is developed, and the specific surface area is 1000-1500m 2 / g, is a kind of adsorption material with strong adsorption capacity (Fan Qiang, Gu Ping, et al. [J]. Industrial Water Treatment, 2014.04). Activated carbon has the advantages of fast filtration speed, good adsorption performance, strong decolorization and deodorization ability, economical and durable, etc. The products are widely used in food, beverage, medicine, tap water, sugar, oil and other in...
