Description

Technical Field

[0001] The invention relates to the field of hydrogen peroxide production technology, in particular to a hydrogen peroxide production working fluid regeneration device. Background Art

[0002] Hydrogen peroxide is a green chemical product with almost no pollution in its production and use process, so it is called a "clean" chemical product. As an oxidant, bleaching agent, disinfectant, deoxidizer, polymer initiator and cross-linking agent, it is widely used in chemical, papermaking, environmental protection, electronics, food, medicine, textile, mining, agricultural waste processing and other industries.

[0003] As the clay bed used in the production of hydrogen peroxide, the main function of the hydrogenated clay bed is to regenerate the working fluid; the purpose of regeneration is to reduce the consumption of anthraquinone raw materials and maintain the cleanliness of the working fluid to ensure the smooth progress of the hydrogenation and oxidation reactions. The anthraquinone degradation products produced during the hydrogenation reaction (such as anthraquinone, hydroxyanthraquinone, octahydroanthraquinone and other degradation products produced by hydrogenation side reactions and epoxy degradation products produced by oxidation side reactions) are mainly regenerated in the clay bed and hydrogenated clay bed, and the regeneration agent is activated alumina.

[0004] Alumina balls are used as regeneration agents. After a period of use, their activity decreases and they need to be replaced regularly. The traditional clay bed includes a skirt, a lower head, a cylinder, and an upper head connected from bottom to top. A grid is installed in the cylinder, and a wire mesh is laid on the grid. There are two manholes above and below. Alumina balls are placed from the upper manhole, and the alumina balls are above the wire mesh.

[0005] There are the following defects in view of the above technical problems: 1. When replacing the waste alumina balls, the alumina balls are not completely discharged from the discharge port automatically. Personnel need to enter the equipment to discharge and replace the alumina balls to the discharge port. Although personnel will take very complete safety protection when entering the confined space to work, there will still be safety hazards; 2. The alumina ball is installed above the wire mesh, and the working fluid in the lower head cannot participate in the reaction, resulting in waste.

[0006] Therefore, there is a need for a working fluid regeneration device that is convenient for safely replacing alumina balls, improves the utilization rate of alumina balls and reduces the waste of alumina balls. Summary of the invention

The rotating motor is installed on the upper head, the driving wheel is coaxially connected to the output shaft of the rotating motor, the driven wheel is coaxially connected to the auxiliary pipe, and the synchronous belt is simultaneously wound around the driving wheel and the driven wheel and kept tensioned.

[0023] By adopting the above technical solution, the limiting circular groove provides a limit for the rotation of the auxiliary tube. When installing the auxiliary tube, when the bottom end of the auxiliary tube abuts against the inner bottom wall of the limiting circular groove, it indicates that the auxiliary tube is installed in place.
