Working solution dehydration device for hydrogen peroxide production

Abstract

According to the technical scheme, the working solution dehydration device for hydrogen peroxide production comprises a tower body, a fixing plate is fixedly connected to the top in the tower body, a blockage clearing mechanism is arranged in the tower body, the blockage clearing mechanism comprises a worm, a transmission rod, a worm wheel and two supporting vertical plates, one end of the worm is fixedly connected with a first connecting rod, and the other end of the worm is fixedly connected with a second connecting rod; the working solution dehydration device for hydrogen peroxide production has the beneficial effects that by arranging the blockage clearing mechanism, when materials flow in a pipeline for a long time due to the influence of external factors, the blockage clearing mechanism can clear the blockage of the materials, and the blockage clearing mechanism can clear the blockage of the materials; a user can drive the multiple liquid pipes to rotate by rotating the hand wheel, and simultaneously drive the multiple dredging rods and the multiple spines to conduct up-and-down reciprocating dredging on liquid in the liquid pipes, pipeline blockage is avoided, basically no energy is consumed, and the problem that steam is wasted in the existing mode that steam is adopted to heat the outer wall of a pipeline to conduct blockage clearing is effectively solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen peroxide production, in particular to a working fluid dehydration device for hydrogen peroxide production. Background technique [0002] The production of hydrogen peroxide by anthraquinone method is currently one of the most mature production methods in this industry in the world, that is, diethyl anthraquinone, heavy aromatic hydrocarbons, trioctyl phosphate, etc. are used to form a working solution, which is hydrogenated under the catalysis of a catalyst, and then oxidized to produce anthracene Quinone and hydrogen peroxide, and then extract the hydrogen peroxide in the working solution with pure water, and the raffinate working solution containing a certain amount of water removes part of the water and enters the clay bed to regenerate the anthraquinone degradation products, and rehydrogenate for cyclic reaction. [0003] In the dehydration process, if the internal and external ambient temper...

AI Technical Summary

Problems solved by technology

[0003] In the dehydration process, if the internal and external ambient temperature is low or the material flows inside the pipeline for a long time due to power failure, equipment failure and other reasons, the crystallization of carriers such as anthraquinone in the raffinate working fluid may cause pipeline blockage, resulting in The equipment cannot run smoothly, and the existing method of using steam to heat the outer wall of the pipeline to unblock is wasteful of steam, and the operator is easily burned, which poses a great safety hazard
