Problems solved by technology

The traditional oxidation tower is a hollow tower body. The hydrogenated liquid and air enter the oxidation tower from the bottom at the same time, and go up while stirring. The air bubbles are relatively large, the contact area between the hydrogenated liquid and air is small, and the oxidation efficiency is relatively low. Usually, an oxidation The upper section tower, the oxidation middle section tower and the oxidation lower section tower have undergone multiple oxidations before entering the extraction process
Large equipment investment and low oxidation efficiency

Description

technical field [0001] The invention relates to a system for producing hydrogen peroxide by an anthraquinone method, and also relates to a method for producing hydrogen peroxide by an anthraquinone method, belonging to the technical field of hydrogen peroxide production. Background technique [0002] Hydrogen peroxide is an important inorganic chemical raw material, widely used in papermaking, textile, medicine, chemical industry, electronics, environmental protection and other fields. Hydrogen peroxide decomposes to produce water and oxygen, which has no secondary pollution to the environment and conforms to the concept of green product production. [0003] In the prior art, hydrogen peroxide is usually produced by the anthraquinone method. The anthraquinone method uses 2-ethylanthraquinone as a carrier and palladium as a catalyst to directly synthesize hydrogen peroxide from hydrogen and oxygen, followed by hydrogenation. , oxidation, extraction and post-treatment process...
