Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide production, in particular to a hydrogen peroxide production filtering device. Background Technique

[0002] Hydrogen peroxide is also called hydrogen peroxide. Pure hydrogen peroxide is a light blue viscous liquid and is a strong oxidant. However, its aqueous solution is commonly called hydrogen peroxide and is a colorless and transparent liquid. Currently, hydrogen peroxide is mainly prepared by the anthraquinone method, in which hydrogen and oxygen react to form hydrogen peroxide. In this method, anthraquinone derivatives are dissolved in an organic solvent to form a working solution. Most processes contain an appropriate amount of tetrahydroanthraquinone in the working solution. Then, the working solution is hydrogenated in the presence of a catalyst to form anthrahydroquinone. The working solution undergoes processes such as hydrogenation, oxidation, extraction, and purification to obtain the finished hydrogen peroxide.

[0003] During the preparation of hydrogen peroxide, the working solution needs to be filtered to remove internal impurities, thereby improving the preparation effect of hydrogen peroxide. Since hydrogen peroxide and its semi-finished products have strong oxidizing properties, the filter element in the filter cartridge needs to be replaced regularly. The current hydrogen peroxide filter has an unreasonable structure and cannot achieve quick disassembly and replacement of the filter element.

[0027] Specifically, first place the filtering device main body 1 at a designated position. The base 2 plays a supporting role for the filtering device main body 1. Then place a plurality of filtering tanks 5 inside the filtering device main body 1, so that the bottom of the filtering tank 5 is embedded in the water storage tank 8 through the through hole 11. Subsequently, connect the water separation hopper 6 to the filtering tank 5 through the connecting component 4, so that the clamping plates 10 outside the plurality of filtering tanks 5 are engaged with the limiting ring 9 at the top of the water storage tank 8.
