Catalytic oxidation adsorption treatment system and method for sulfur-containing tail gas of sulfur recovery device

The invention discloses a catalytic oxidation adsorption treatment system and method for sulfur-containing tail gas of a sulfur recovery device, the catalytic oxidation adsorption treatment system comprises a catalytic oxidation reactor and an oxidation adsorption reactor which are arranged in series, and the catalytic oxidation reactor is arranged at the front end of the oxidation adsorption reactor; the catalytic oxidation reactor is connected with the first heater through a pipeline, the catalytic oxidation reactor is connected with an air inlet pipe, and the catalytic oxidation reactor is filled with an oxidation catalyst and used for oxidizing sulfide in sulfur-containing tail gas generated by a sulfur recovery device into sulfur dioxide; and the oxidation adsorption reactor is filled with an oxidation adsorbent for adsorbing sulfur dioxide. The mass concentration of sulfur dioxide in the sulfur-containing tail gas treated by the system is less than 50mg/m < 3 >, no wastewater is generated, and corrosion
