This invention provides an adsorption device for hydrogen peroxide oxidation tail gas, comprising an adsorption tank, an inner filter cartridge, an outer filter cartridge, an adsorption chamber, several air inlets, an adsorption resin layer, an inlet pipe, and an outlet pipe; both the inner and outer filter cartridges are located inside the adsorption tank. This invention optimizes the traditional "flat-lay" structure into a "sleeve-type" coaxial double-layer filter cartridge structure, improving the contact efficiency between the tail gas and the resin, preventing the resin from being blown away or worn, extending its service life, and simplifying the filling process. The elimination of quartz sand filler also simplifies the filling process. The system adopts a "five-in-one-out" operating mode, enabling multiple adsorption tanks to operate in rotation. Combined with steam regeneration, nitrogen purging, and spray cooling processes, it achieves efficient resin regeneration and reuse, significantly reducing operating energy consumption and material replacement frequency. The adsorption system operates stably, has a compact structure, and can continuously and efficiently remove aromatic organic pollutants from the oxidation tail gas, balancing operational economy and environmental friendliness.
