Abstract
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.
