Abstract

The invention belongs to the technical field of air purification, in particular to an adsorption-degradation filter element and an air purifier using the same. The filter element comprises a mixture of active carbon and titanium dioxide or a composite layer structure of active carbon and titanium dioxide; the filter element takes the active carbon as a carrier to form a circulation process consisting of carrier adsorption, surface diffusion, photocatalytic degradation, in-situ regenerative adsorption capability and re-adsorption of pollutants; and synergistic effect of adsorption and photocatalytic degradation is generated and the purification effect is far more than the total purification effect of a filtering unit and a photocatalyst in the prior art, thus achieving an effect that one plus one is greater than two. Compared with the conventional air purifier, the air purifier using the adsorption-degradation filter element has the advantages of reasonable design, simple structure, device miniaturization, small floor area, composite air purification, high purification efficiency and the like, and can be widely applied to places such as houses, vehicles, and the like.

Description

technical field

[0001] The invention belongs to the technical field of air purification, and in particular relates to an adsorption degradation filter element and an air purification device using the filter element. Background technique

[0002] With the improvement of living standards, people have higher and higher requirements for living environment and office environment, and air purifiers, as a device that can remove dust and bacteria in the air, are widely used in homes, offices and other occasions.

[0003] The purification principles of existing air purifiers are generally divided into two types. One is to use filtering units such as filter screens and activated carbon layers to filter the air. This method can only filter and absorb dust and harmful gases in the air, but does not It does not have the function of decomposing harmful gases and sterilizing, and the filter unit needs to be cleaned and replaced frequently; the other is the use of photocatalyst technology, ...
