Abstract

The invention relates to a fluidized bed production system and production method for hydrogen peroxide. The bottom of a working liquid tank is connected with an inlet of a hydrogenation device through a working liquid pump and a working liquid supply pipe; an outlet of the hydrogenation device is connected with a hydrogenated liquid tank through a net hydrogenated liquid outlet pipe; the bottom of the hydrogenated liquid tank is connected with the inlet of an oxidation tower through a hydrogenated liquid pump, a hydrogenated liquid tank outlet pipe, a hydrogenated liquid filter and a hydrogenated liquid cooler; the outlet of the oxidation tower is connected with an oxidized liquid output pipe; the bottom of a hydrogenation reactor is connected with the working liquid supply pipe and a fresh hydrogen supply pipe; the outlet of the reactor on the middle circumference of the hydrogenation reactor is connected with the middle circumference of a catalyst preseparator along the tangential direction; the bottom of the catalyst preseparator is connected with the lower circumference of the hydrogenation reactor; the outlet of the catalyst preseparator is connected with a bottom inlet of a catalyst filter through a three-way valve; and the top of the catalyst filter is connected with the net hydrogenated liquid outlet pipe. According to the system, continuous production can be achieved, the unit consumption of a product is low, and the production efficiency is high.

Description

technical field [0001] The invention relates to a fluidized bed production system of hydrogen peroxide, and also relates to a production method of fluidized bed hydrogen peroxide, which belongs to the technical field of hydrogen peroxide manufacturing equipment. 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. Amon...
