Abstract

The invention discloses a device for producing hydrogen peroxide by adopting an anthraquinone process. The device comprises a hydrogenation reaction unit, an oxidation reaction unit and an extraction separation unit. A loop reactor with a simple structure is used for replacing the current hydrogenation and oxidation reaction equipment with huge volume, and a static mixer and an oil and water separator which are very small in volume are used for replacing an extraction tower with huge volume and low efficiency, thus the production process is simple, the volume of the equipment is very small, the investment scale of the device is saved, and the investment is saved by about 80 percent in comparison with that of a device for producing hydrogen peroxide with the same capacity.

Description

technical field [0001] The invention relates to a hydrogen peroxide production device, in particular to an anthraquinone method hydrogen peroxide production device. Background technique [0002] Hydrogen peroxide is a green chemical product, and its production and use are almost pollution-free, so it is called a "clean" chemical product, and its application prospects are increasingly promising. At first, hydrogen peroxide was only used in medicine and military industry, but it was gradually used in chemical synthesis, textile, papermaking, environmental protection, food, medicine, metallurgy and agriculture, and the market demand is expanding day by day. [0003] There are many ways to produce hydrogen peroxide, among which the production of hydrogen peroxide by the anthraquinone method is one of the most mature production methods in the world at present. Large-scale foreign manufacturers all use the anthraquinone method to produce hydrogen peroxide. At present, the producti...
