Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon processing equipment, specifically a carbonization device for high-efficiency activated carbon production. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials are heated in the absence of air to reduce non-carbon components, and then react with gases. The surface is eroded, creating a structure with well-developed micropores. Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, which results in countless tiny pores on the surface of activated carbon. The diameter of the micropores on the surface of activated carbon is mostly between 2 and 50 nm. Even a small amount of activated carbon has a huge surface area. Almost all applications of activated carbon are based on this characteristic.

[0003] In the processing of activated carbon, the carbonization environment of wood is generally air, containing gases such as carbon dioxide and sulfur dioxide. During the carbonization process, not only is calcium oxide powder or calcium oxide powder easily consumed, but calcium sulfate or calcium carbonate precipitates are also easily generated and adsorbed on the activated carbon particles. This reduces the adsorption capacity of the powder, thereby affecting the phosphorus removal effect. Moreover, after high-temperature carbonization, the temperature of the activated carbon is too high, making it difficult to remove manually. Therefore, those skilled in the art have proposed a carbonization device for high-efficiency activated carbon production to solve the problems mentioned in the background. Utility Model Content
