Description

Technical Field

[0001] The utility model relates to the technical field of anthraquinone process hydrogen peroxide production, in particular to an automatic discharging type clay bed fixed liquid reactor. Background Technique

[0002] In the process of producing hydrogen peroxide by the anthraquinone method, the clay bed plays a crucial role. Specifically, the functions of the clay bed are as follows:

[0003] 1. Regenerate oxidized degradation products: In the production of hydrogen peroxide, the design of the hydrogenated liquid clay bed is to regenerate oxidized and hydrogenated degradation products under the condition of the existence of tetrahydroanthraquinone. This is because the temperature of the hydrogenated liquid is usually about 10 degrees higher than the temperature of the post-treatment working fluid, so that the regeneration ability and effect of the hydrogenated liquid clay bed are more obvious. This design helps to improve the production efficiency and product quality of hydrogen peroxide.

[0004] 2. Adsorb impurities in the working fluid: In addition to regenerating oxidized degradation products, the clay bed is also used to adsorb impurities in the working fluid, such as potassium carbonate solution and moisture. If these impurities are not removed in time, they may have an adverse impact on the hydrogen peroxide production process, reducing product quality and even affecting production safety.

[0005] 3. Regular replacement to ensure stable production: In order to ensure a stable production process and product quality, the activated alumina balls (clay) in the hydrogenated clay bed and the post-treatment clay bed need to be replaced regularly. This is because during use, these activated alumina balls (clay) will adsorb a certain amount of impurities and degradation products, and need to be replaced after reaching saturation to ensure their regeneration ability and adsorption effect.

[0006] 4. Prevent production accidents: In the process of hydrogen peroxide production, the correct use of the clay bed is also crucial for preventing production accidents. For example, if the activated alumina ball (clay) powder in the clay bed enters the oxidation tower with the hydrogenated liquid, it may cause the decomposition of hydrogen peroxide, resulting in an increase in the pressure and temperature in the tower, thus triggering a safety accident. Therefore, ensuring the normal operation and maintenance of the clay bed is one of the important measures to ensure production safety. To sum up, the role of the clay bed in hydrogen peroxide production cannot be ignored. It ensures the high-efficiency, safe and stable production of hydrogen peroxide by regenerating oxidized degradation products and adsorbing impurities in the working fluid.

[0007] After the activated alumina balls inside the clay bed reach saturation, they need to be discharged. The traditional process of replacing the activated alumina balls in the clay bed is relatively troublesome. Content of the Utility Model
