Problems solved by technology

[0003] 1. Uneven distribution of oxidizing solution
[0004] 2. Since the opening of the tubular distributor is facing downward, the oxidizing solution is easy to condense together when it floats upward after being distributed, and the diffusion effect of hydrogen peroxide is poor.

Abstract

The invention discloses an anthraquinone method hydrogen peroxide extraction tower, belongs to the anthraquinone method hydrogen peroxide production extraction technology field, and especially relates to a structure of the anthraquinone method hydrogen peroxide extraction tower. The structure of the tower comprises a shell, the internal of the shell is fixedly connected with a sieve plate, the shell is fixedly connected with a pure water inlet tube, an oxidation liquid inlet total tube, a hydrogen peroxide product outlet tube, a raffinade outlet end and an escape tueb which are communicated with the inner cavity of the shell, the oxidation liquid inlet total tube is connected with a plurality of branch tubes, the other end of each of the branch tubes is connected with a distribution head, the distribution head is upward arranged, a cover plate is arranged over the distribution head, the cover plate is provided with a plurality of oxidation liquid distribution holes, a press ring is arranged over the cover plate, and the press ring is connected with one corresponding distribution head through a bolt. The structure of the extraction tower has the advantages of uniform distribution of the oxidation liquid, reduction of the content of hydrogen peroxide in a raffinade at the top of the extraction tower, and production of high-concentration hydrogen peroxide products at the bottom of the extraction tower.

Description

technical field [0001] The invention belongs to the technical field of production and extraction of hydrogen peroxide by anthraquinone method, and in particular relates to the structure of an extraction tower for hydrogen peroxide by anthraquinone method. Background technique [0002] The existing structure of the extraction tower is that after the oxidation liquid enters the extraction tower, only a tubular distributor is used to distribute the liquid. The following defects exist in the current equipment: [0003] 1. The oxidizing solution is unevenly distributed. [0004] 2. Since the opening of the tubular distributor faces downward, the oxidizing solution is easy to condense together when it floats upward after being distributed, and the diffusion effect of hydrogen peroxide is poor. [0005] 3. Due to the columnar distribution of the oxidizing liquid distributed by the tubular distributor, the hydrogen peroxide in the oxidizing liquid is not easy to diffuse into the pu...
