Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide production, in particular to an automatic alkali steaming device for hydrogen peroxide. Background Art

[0002] The anthraquinone method is the main method for producing hydrogen peroxide. The process is to prepare a working solution of alkyl anthraquinone and an organic solvent, introduce hydrogen for hydrogenation under the conditions of a pressure of 0.30MPa, a temperature of 55-65°C and the presence of a catalyst, and then countercurrently oxidize with air at 40-44°C. After extraction, regeneration, refining and concentration, a hydrogen peroxide aqueous solution product with a mass fraction of 20%-30% is obtained. The anthraquinone method has a high degree of technical automation control, low product cost and energy consumption, and is suitable for large-scale production.

Therefore, phenomena such as unbalanced solution feeding and discharging are prone to occur. In addition, the existing device only uses a single stirring rod to mix the solution, resulting in the inability to fully mix the solution at the periphery and center of the reaction tank.
