Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection in aluminum oxide production, and more specifically, to a gas extractor with a gas purification function. Background Art

[0002] Alumina production is a key link in aluminum smelting and is mainly obtained through the extraction and processing of bauxite. The main component of bauxite is bauxite ore (bauxite), whose main components are diaspore (gibbsite), alundum and bauxite. During the production process, the aluminum in the bauxite is first converted into aluminum oxide through grinding and leaching processes. Then, the aluminum oxide is reduced to aluminum metal by high-temperature electrolysis. The whole process requires a large amount of energy, especially electricity, and will also produce certain environmental pollution, especially high-temperature alkaline liquids and solid waste.

[0003] High-temperature alkaline liquid usually refers to a solution containing sodium hydroxide formed during the extraction process of bauxite, with a pH value generally exceeding 8. This liquid plays a key role in the leaching process of aluminum oxide. By reacting with aluminum minerals in bauxite, the aluminum in the bauxite enters the liquid phase and is separated from the solid phase. High-temperature alkaline liquid will produce alkaline water vapor, which is usually discharged directly into the atmosphere through a pump at home and abroad. The direct discharge of untreated alkaline water vapor will cause acid-base imbalance in the water body, affect the ecosystem, and even harm human health. It also causes the loss of valuable alkali. Therefore, the development of effective treatment and purification technologies to reduce the impact of high-temperature alkaline liquid on the environment is an important challenge facing the aluminum production industry.
