Abstract

The invention relates to a system and method for producing hydrogen peroxide through a fluidized bed. The bottom of a working liquid tank is connected with an inlet of a hydrogenation reaction device through a working liquid pump and a working liquid supply pipe; an outlet of the hydrogenation reaction device is connected with a hydrogenated liquid tank; the bottom of the hydrogenated liquid tank passes through a hydrogenated liquid pump, a hydrogenated liquid tank output pipe, a hydrogenated liquid filter and a hydrogenated liquid cooler and is connected with the inlet of an oxidation tower; the outlet of the oxidation tower is connected with an oxidized liquid outlet pipe; the outlet of a hydrogenation reaction kettle is connected with catalyst filters; the outlets of the catalyst filters are connected with a hydrogenated liquid outlet pipe and a hydrogenated liquid working liquid backwashing pipe respectively; and the bottoms of the catalyst filters are connected with a working liquid supply pipe; multiple oxidation tower trays are arranged in the oxidation tower, down-flow openings and down comers are arranged on various layers of oxidation tower trays respectively; and the down-flow openings in odd layers are located in the axis of the oxidation tower, and the down-flow openings in even layers are symmetrically formed and are close to the inner wall of the oxidation tower. The system is capable of achieving continuous production, and is small in floor area, low in unit consumption of a product and high in production efficiency.

Description

technical field [0001] The invention relates to a system for producing hydrogen peroxide in a fluidized bed, and also relates to a method for producing hydrogen peroxide, which belongs 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 processes. Among them, the hydrogenat...
