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
The invention belongs to anthraquinone hydrogen peroxide and produce the abstraction technique field, relate in particular to the structure of anthraquinone extraction column of hydrogen peroxide.
Background technology
Existing extraction tower structure is after oxidation solution enters extraction tower, only depends on a tubulose sparger to carry out liquid distribution, has at present following defect in equipment:
1, oxidation solution skewness.
2, due to the perforate of tubulose sparger down, oxidation solution is backward easily agglomerated together when floating through distributing, the hydrogen peroxide diffusion effect is poor.
3, the oxidation solution distributed due to the tubulose sparger is column and distributes, and makes the hydrogen peroxide in oxidation solution be not easy to be diffused in pure water, makes in the raffinate at extraction tower top hydrogen peroxide content high, and the raffinate hydrogen peroxide content reaches the 0.4g/l left and right when the highest.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the anthraquinone extraction column of hydrogen peroxide that provides a kind of oxidation solution to be evenly distributed, reduce the hydrogen peroxide content in the raffinate of extraction tower top, hydrogen peroxide product that simultaneously can the production high density at the bottom of extraction tower.
The object of the present invention is achieved like this: a kind of anthraquinone extraction column of hydrogen peroxide, comprise housing, be fixedly connected with sieve plate in housing, be fixedly connected with the purified water inlet pipe with the housing intracavity inter-connection on housing, the oxidation solution intake header, hydrogen peroxide products export pipe, raffinate outlet pipe and blow-down pipe, connect some shape pipes on described oxidation solution intake header, the other end of every shape pipe connects respectively distribution head, each distribution head arranges respectively upward, the top of each distribution head arranges respectively cover plate, several oxidation solution distribution holes are set respectively on every cover plate, the top of every cover plate arranges respectively pressure ring, each pressure ring is bolted respectively with corresponding distribution head.
The invention has the beneficial effects as follows: 1, extraction tower changes the former tubulose sparger of oxidation solution import into the oxidation solution injector, the perforate of distribution jet hole upwards, oxidation solution is after injector sprays, be dispersed into numerous tiny liquid fluidization tower, make the hydrogen peroxide in oxidation solution be diffused in pure water and go quickly, make the hydrogen peroxide content in the raffinate of extraction tower top be reduced to the 0.1g/l left and right by original 0.4g/l left and right, hydrogen peroxide plant with respect to 100,000 tons of annual production, annual can reclaim 4800 tons of the hydrogen peroxide products that concentration is 27.5% more, be worth 3,800,000 yuan.
2, sparger is evenly distributed oxidation solution, and the hydrogen peroxide content in raffinate is low, and because the hydrogen peroxide content in raffinate has reduced, hydrogen peroxide product that can the production high density at the bottom of extraction tower, make the hydrogen peroxide product concentration bring up to 35% by original 27.5%.
In order to prevent that oxidation solution from leaking, the oxidation solution bias current, arrange respectively pad between every cover plate and corresponding distribution head.
