Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide extraction towers, in particular to a large hydrogen peroxide extraction tower. Background Art

[0002] Hydrogen peroxide is one of the important products of the inorganic salt industry and a strong oxidant. The production process of hydrogen peroxide is to produce a mixture of working fluid and hydrogen peroxide through hydrogenation and oxidation, and then extract it with desalted water in an extraction tower to produce hydrogen peroxide. The raffinate, i.e. the working fluid, is returned to the hydrogenation unit for recycling after removing the small amount of hydrogen peroxide it contains. In the hydrogen peroxide production process, the extraction tower is one of the core key equipment.

[0003] When using an existing hydrogen peroxide extraction tower, water is transported into the extraction tower through a water inlet pipe. However, when the water is left, it contains impurities, which makes it difficult to filter it, reducing the extraction effect and the use effect, and making it inconvenient for workers to operate. Therefore, a large hydrogen peroxide extraction tower is proposed to solve the above problems. Utility Model Content
