Problems solved by technology

A new way of activator feeding is provided, and the amount of water vapor generated is precisely controlled by the feeding of oxygen. At the same time, the heat released by the combustion of hydrogen and oxygen is used, which not only saves energy, but also improves the activation efficiency. However, this Invention process is cumbersome and difficult to operate
[0007] Therefore, it is necessary to improve the activated carbon preparation process in view of the high cost of raw materials in the current activated carbon preparation process, the waste of resources in the activation process, and the low heat of the process.

Abstract

The invention discloses a preparation process of activated carbon. The preparation process of the activated carbon comprises the processes of raw material preparation, raw material drying, carbonization and front-end activation. According to the preparation process of the activated carbon, branch firewood, wood waste firewood, bamboo heads and the like are adopted as raw materials, cutting of tree vegetation is avoided, the ecological environment is protected, meanwhile, a retrograde method is adopted in the activation process, carbon monoxide and hydrogen generated by water gas reaction at the front end of an activation cylinder directly make contact with oxygen in air to be combusted, a large amount of heat is generated to be consumed by a carbonization cylinder and a boiler, the process cost is reduced, and meanwhile, the boiler also has surplus heat for sale, so that the income is increased, and the heat utilization effect is greatly improved.

Description

Technical field [0001] The present invention relates to the field of activated carbon, and more particularly to the preparation process of activated carbon. Background technique [0002] Activated carbon is a specially treated carbon, which heats the organic raw material such as fruit shell, coal, wood in isolation of aerosol, and then reacts with the gas, the surface is eroded, producing a microporous developed structure. Since the active carbon microporous structure is developed, the specific surface area and the adsorption activity are widely used in the field of sewage treatment, electrodes, flue gas treatment. [0003] The main raw material of activated carbon is charcoal. Most producers will go to the forest resources to produce charcoal production of charcoal. This production method is based on live forest, leading to serious deforestation, and the forest vegetation is seriously destroyed. ecosystem. [0004] As the state attaches importance to the ecological environment, ...
