Abstract

The invention discloses an oxidation system for producing hydrogen peroxide in the field of chemical equipment. In the oxidation system, the outlet of a phosphoric acid preparation tank and a hydride source are communicated with the inlet of a hydride pump; the outlet of the hydride pump is communicated with the bottom of an upper tower; the inlet of a compressed air filter is communicated with a compressed air source; the outlet of the compressed air filter is divided into two paths, one path is communicated with the bottom of the upper tower, and the other path is communicated with the bottom of a lower tower; the number of oxidizing solution coolers is two; an oxidizing solution outlet at the top of the upper tower is communicated with the bottom of a middle tower after passing through one oxidizing solution cooler; an oxidizing solution outlet at the top of the middle tower is communicated with the bottom of the lower tower after passing through the other oxidizing solution cooler; and the tail gas at the tops of the middle and upper towers can be condensed for recycling. When the system works, main reaction is performed in the upper and middle towers and complete oxidation reaction is performed in the lower tower, so that hydride can be more fully oxidized and the yield can be improved. The oxidation system is particularly used for producing the hydrogen peroxide.

Description

Technical field [0001] The invention relates to a production equipment for hydrogen peroxide, in particular to a production equipment for the hydrogenation process in the production of hydrogen peroxide by an anthraquinone method. Background technique [0002] At present, the main production method of hydrogen peroxide is the anthraquinone method. After extensive research and improvement by companies in various countries, this method has become the most dominant method for producing hydrogen peroxide in the world, almost completely replacing the electrolysis method. This method uses anthraquinone derivatives (mainly 2-alkylanthraquinone) as a catalyst carrier. In the presence of a catalyst, 2-alkylanthraquinone (AQ) dissolved in a suitable organic solvent is hydrogenated with hydrogen to generate the corresponding 的2-alkylhydroanthraquinone (HAQ). After the HAQ in the solvent is separated from the catalyst, it can be oxidized with air or oxygen-enriched gas to generate H2O2, and ...
