Abstract
The utility model provides a device for hydrogen peroxide extraction. The device structurally comprises a stock solution jar, a separating jar, a liquid distributor, a rectifier, a drop multiplying fiberfill component, a special plate combined type separating component and an anti-vortex baffle component, wherein the drop multiplying fiberfill component and the special plate combined type separating component are arranged in the separating jar; a small dispersed phase discharging barrel is arranged on the separating jar, for stabilizing two-phase interface and preventing the entrainment of the discharged dispersed phase; and an anti-vortex baffle is arranged in the separating jar, thereby preventing the discharged material from forming vortex, stabilizing the flow field in the separating jar and enhancing the separating effect.
