Embodiment Construction
[0027] A device and process applied to hydrogen peroxide extraction, which is characterized in that its structure includes a raw liquid tank 2, a separation tank 12, a liquid distributor 1, a rectifier 13, a droplet multiplying fiber packing component 4, a special plate group separation component 5. Anti-vortex baffle assembly 8. The droplet multiplying fiber packing component 4 and the separation special plate group separation component 5 are arranged in the separation tank. The separation tank 12 is provided with a small cylinder for discharging the dispersed phase to stabilize the two-phase interface and prevent the lye from entraining materials; the separation tank is provided with an anti-vortex baffle 8 to stabilize the flow field in the separation tank and enhance the separation effect. After the raw material enters the original liquid tank 2, it enters the separation tank 12 through the rectifier 13, passes through the 4 droplet multiplying packing separation groups fir...

The invention provides a device and process applied to hydrogen peroxide extraction. The device comprises a stock solution tank, a separating tank, a liquid distributor, a rectifier, a liquid drop multiplication fiber filler assembly, a special plate group separating assembly and an anti-vortex baffle plate assembly, wherein the liquid drop multiplication fiber filler assembly and the special plate group separating assembly are arranged in the separating tank; the separating tank is provided with a small dispersed phase discharge barrel for stabilizing a two-phase interface and preventing discharging inclusion of a dispersed phase; and the anti-vortex baffle plate assembly is arranged in the separating tank and is used for preventing discharging vortex, stabilizing flow field in the separating tank and enhancing a separating effect. The separating equipment can reach dozens of ppm in maximum. Due to the adoption of a rare product phase separator, separating time is shortened, equipment size is reduced, and the load of subsequent air blow-off aromatic hydrocarbon and the emission of aromatic hydrocarbon can be lowered.
Description
Technical field [0001] The invention relates to a device and a technological process of an extraction section in a hydrogen peroxide production process. Background technique [0002] At present, the anthraquinone process is widely used in the production of hydrogen peroxide. This process is relatively mature and has achieved large-scale industrial production. The anthraquinone process mainly includes a hydrogen chemical section, an oxidation section and an extraction purification section. The process of the extraction purification section is: the raffinate flowing out of the top of the extraction tower is separated by a raffinate separator to remove part of the water that may be entrained, and then enters the bottom of the drying tower. The drying tower is filled with potassium carbonate solution to remove part of the water, neutralize acids and decompose residual hydrogen peroxide. The working liquid flowing from the top of the drying tower enters the lye separator to separate...
