Description

Technical Field

[0001] The invention relates to environmentally friendly recycling equipment and methods for removing organic matter, in particular to environmentally friendly recycling equipment and methods for removing organic matter from sodium aluminate solution in an alumina system, and belongs to the technical field of alumina production. Background Art

[0002] The organic matter in the sodium aluminate solution mainly exists in the form of organic acids, such as acetic acid, succinic acid, oxalic acid, propionic acid, formic acid, etc. It also contains a small amount of dibasic organic acids such as glutaric acid and phthalic acid. These organic acids affect the physical and chemical properties of the solution. Organic matter changes the physical properties of the solution, such as specific gravity, viscosity, boiling point, specific heat, etc., reduces the interfacial tension, and increases the viscosity of the alkali solution. It will also increase the loss of the pump and reduce the economic benefits. Moreover, its discharge will directly affect the surrounding environment and cause environmental pollution. Organic matter can be adsorbed on the surface of the crystal, hindering the growth of the crystal, making the particle size of the product aluminum hydroxide finer and fragile, and easy to break during filtration, especially during calcination. At the same time, organic matter will also reduce the decomposition rate of the seed crystal, affecting the output and quality of alumina.

[0003] Therefore, in the production process of alumina, it is necessary to remove organic matter in the sodium aluminate solution. At present, aluminum hydroxide washing solution is often used for washing, and then hot water is used for secondary washing. The washing wastewater is usually discharged directly, or liquid alkali is added to the obtained second washing solution to increase the causticity ratio of the solution to more than 6, and then lime milk is added for causticization reaction. The causticized slag is separated by a sedimentation tank to reduce the concentration of organic matter in the solution. The process is complicated and requires a large amount of water resources for washing. It is inefficient and will cause damage to the surrounding environment, causing soil alkalization, which is not conducive to the growth of crops and damages the environment.

[0004] Therefore, there is an urgent need to improve the environmentally friendly recycling equipment for removing organic matter from sodium aluminate solution to solve the above-mentioned problems. Summary of the invention

The structure is simple and the convenience of use is improved. The environmental protection reaction barrel cover plate 601 is connected to the oxygen production mechanism 5, and the oxygen production mechanism 5 includes an electrolytic generator 501 and a hydrogen burner 502.

When the first electric telescopic rod 301 is braked downward, the sealing plate 305 is used to seal the guide support tube 201. After the oxidation is completed and concentrated, the filter plate 302 is pushed upward by starting the first electric telescopic rod 301, and the sealing plate 305 is separated from the upper port of the guide support tube 201. The organic matter in the sodium aluminate solution after impurities are removed flows out of the guide support tube 201 and is collected. The filter plate 302 continues to rise, pushes the impurities upward, and takes them out from the port of the environmental protection reaction barrel 1 and recycles them.
