Automatic production line for powdered activated carbon regeneration

Abstract

The invention discloses an automatic production line for powdered activated carbon regeneration. The automatic production line comprises a heating combustion furnace connected with a dryer. A spiral feeding device is connected to the side wall of the lower portion of the dryer. A cyclone separator is connected to the top end of the dryer through a pipeline. A sand remover is connected to the bottom of the cyclone separator. A second pulse cloth bag dust remover is connected to the bottom of the sand remover. The bottom of the second pulse cloth bag dust remover is connected with one end of a gasification furnace through a feeding spiral device. The other end of the gasification furnace is connected with a smoke cooling channel. The smoke cooling channel is connected with a pulse dust remover through a condensation pipe. The automatic production line overcomes the defect that due to the fact that sundries like gravels in the raw material are sintered at high temperature and caked, a traditional cyclone activating furnace is shut down, and has the advantages of being high in automation degree, saving energy, and being efficient and high in practicality.

Description

technical field [0001] The invention belongs to the technical field of automatic production lines, in particular to an automatic production line for regenerating powdered activated carbon. Background technique [0002] my country is the world's largest activated carbon producer, carbon consumer and activated carbon exporter. The annual output reaches 350,000 tons, and the domestic market uses up to 200,000 tons of carbon, and the market demand increases by more than 20% every year. About 160,000 tons of waste carbon slag are discarded or landfilled for a long time due to lack of scientific and rational development and utilization in China, which not only seriously wastes scarce carbon resources but also pollutes the environment. However, activated carbon waste carbon is a rare renewable resource. The development of activated carbon regeneration process and technology can not only effectively solve the problem of insufficient production capacity of activated carbon, but also ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many ways to regenerate activated carbon, such as: heating regeneration method, wet oxidation method, biological regeneration method, etc. Heating regeneration is widely used in industrial production because of its good versatility. It is a cyclone regeneration furnace, but this kind of furnace usually causes production shutdown due to high-temperature sintering of sand and gravel in the raw materials, which in turn affects its promotion
