Description

Technical Field

[0001] The utility model relates to the field of hydrogen peroxide preparation, in particular to a device for rapid on-site preparation and storage of hydrogen peroxide. Background Art

[0002] Hydrogen peroxide, also known as hydrogen peroxide, has the chemical formula H2O2. It is a blue, viscous liquid with a slightly pungent odor. It is relatively stable in the dark but readily decomposes into oxygen and water when exposed to heat, light, or certain impurities. It is miscible with water in all proportions. Because its oxidation state is -1, hydrogen peroxide can be used as a (strong) oxidizing agent, (weak) reducing agent, and bleaching agent. It is widely used in inorganic synthesis (such as the production of sodium perborate), organic synthesis (such as the production of peracetic acid), medical disinfection, clinical chemistry, dyeing and bleaching, and food testing.

[0003] Authorization Announcement No. CN108862205B, a hydrogen peroxide preparation device and new process equipment for chemical production processes. The invention does not apply to a device comprising multiple ebullating beds connected in series, comprising a hydrogenation tower, an oxidation tower, an extraction and separation tower, and a vacuum packing tower. The hydrogenated liquid obtained from the hydrogenation tower flows through the oxidation tower for gas-liquid separation. The working liquid, after multi-stage extraction in the extraction and separation tower, enters the vacuum packing tower for concentration into hydrogen peroxide. This application achieves efficient operation, low consumption, energy conservation and emission reduction, reduced side reactions, and ensures production safety.
