摘要： A filter element for coupling adsorption and regeneration of volatile organic compounds and a purification device are provided. The filter element includes a filter element body, a photocatalytic mechanism and adsorption-filtration body(s). The adsorption-filtration body(s) may be of a hollow columnar structure where the photocatalytic mechanism is located. VOCs are quickly adsorbed by the adsorption-filtration body(s), then thermal desorption regeneration is performed on the adsorption-filtration body(s) during a time interval of stopping discharging of the exhaust gas, and a photocatalysis technology is used to cyclically purify the thermally desorbed VOCs, which achieves the synergy of high-density and purification in the two technologies. Furthermore, it takes full advantages of high adsorption, filtration and purification efficiency, low photolysis catalysis costs, and easy operation and maintenance of the on-site regeneration.
