High-performance composite filter element

The utility model belongs to the field of purification protection, and particularly relates to a high-performance composite filter element. The high-performance composite filter element is of a cylindrical axial air inlet and circumferential air outlet structure and is mainly composed of a filter unit and an adsorption unit, the filter unit is an independent component, the filter unit and the adsorption unit are combined into a whole through an upper cover of the filter unit, and the filter element sequentially comprises the filter unit and the adsorption unit from inside to outside. Nuclear radioactive dust, biological warfare agent aerosol, chemical toxic smoke, toxic fog and other toxic and harmful aerosol, vaporous chemical toxic agents and industrial toxic and harmful gas can be removed. The filter element adopts the most compact structural design on the premise of meeting the requirements of filtering efficiency, protection efficiency and protection types, and maximizes the filling amount, the specific
