Activated carbon regeneration device and method

Abstract

The invention relates to the field of preparation for activated carbon, and in particular relates to an activated carbon regeneration device and method. The method comprises the following steps of feeding waste powdery activated carbon to a drying converter by using a feeding system, enabling the waste powdery activated carbon to pass through a carbon collector, a dust collector, a hopper and a charger, feeding dried powder into a boiling activation furnace, and activating the waste powdery activated carbon in the high-temperature boiling activation furnace; and enabling the formed powdery activated carbon and furnace gas to pass through a superheated steam heater in a pipeline, reheating steam, feeding the relatively high-temperature powdery activated carbon and furnace gas to a cyclone separator, and enabling the collected activated carbon to pass through a cooling feeder to be packaged or post-treated. According to the technical scheme, the activated carbon regeneration cost is low, the regeneration quality is high, a configured activated carbon drying and superheated steam boiling activation equipment system is reasonable in integral design, easy to run and environmentally-friendly, energy resources are recycled, the production cost is lowered, and the activated carbon can be automatically regenerated in a large scale.

Description

technical field [0001] The invention relates to the field of activated carbon preparation, in particular to an activated carbon regeneration device and a regeneration method. Background technique [0002] With the development of activated carbon manufacturing industry and the expansion of its application fields, it is necessary to regenerate activated carbon no matter from the perspective of economic benefits or environmental protection, which has become an important part of activated carbon production and use technology. Whether activated carbon is discarded after being used once or recycled after regeneration is not only an important symbol reflecting the technical level of the activated carbon industry, but also a choice problem that enterprises using activated carbon need to face. In recent years, domestic research, development, and implementation of activated carbon regeneration have achieved certain results. Among them, activated carbon regeneration techniques are rela...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the high-temperature thermal regeneration method are: the loss of carbon during the thermal regeneration process is relatively large, generally 5-10%, the mechanical strength of the regenerated carbon decreases, and the chemical structure of the carbon surface changes; in addition, the equipment required for thermal regeneration is relatively complicated, and the operating costs High, not easy to miniaturize

It uses the high-temperature gas generated by the combustion of air and gas to regenerate the activated carbon. The high-temperature gas contains part of oxygen, which will oxidize and burn the activated carbon under high temperature conditions, and the efficiency is not high.
