Title:
MICRO-INTERFACE ENHANCED OXIDATION SYSTEM AND OXIDATION METHOD FOR PREPARING HYDROGEN PEROXIDE
Document Type and Number:
WIPO Patent Application WO/2023/284028
Kind Code:
A1
Abstract:
A micro-interface enhanced oxidation system and oxidation method for preparing hydrogen peroxide. The micro-interface enhanced oxidation system comprises an oxidation reaction column (1); a liquid phase pipeline (11) used for conveying hydrogenated anthraquinone is provided at the top of the side surface of the oxidation reaction column (1), and a gas phase pipeline (12) used for conveying air is provided at the bottom of the side surface of the oxidation reaction column (1); a liquid distributor (17), a filler segment (16), a liquid receiving disc (15), and a mixed micro-interface unit (13) are sequentially arranged in the oxidation reaction column (1) from up to down, wherein the mixed micro-interface unit (13) comprises an upper micro-interface generator (131) and a lower micro-interface generator (132) that are communicated with each other in an up-to-down direction; and the conveyed hydrogenated anthraquinone is distributed by the liquid distributor 17 and then sequentially downwardly flows until being mixed, dispersed, and crushed with air in the mixed micro-interface unit (13). By using the micro-interface enhanced oxidation system, the utilization rate of oxygen can be improved, the occupied area is small, and operation is simple and convenient.
