Problems solved by technology

However, it is difficult to effectively utilize this type of activated carbon in a filter unit with limited space
[0006] In addition, conventional activated carbon filter layers are non-renewable, if used in conjunction with some long-life high-efficiency filters, the adsorption life of activated carbon is much lower than that of filter The life of the filter paper, often a filter needs to be equipped with several activated carbon filter layers to meet the demand, resulting in increased user costs and inconvenience

Abstract

The invention belongs to the technical field of air filter materials, and particularly relates to a nano photocatalyst-active carbon fiber composite filter medium. The nano photocatalyst-active carbon fiber composite filter medium is characterized in that the filter medium consists of a nano photocatalyst-active carbon fiber non-woven fabric and a filter base material, wherein the nano photocatalyst-active carbon fiber non-woven fabric comprises the following components in percentage by weight: 0.5 to 1.0 percent of nano photocatalyst, 1.0 to 4.0 percent of nano active carbon and 95 to 98.5 percent of carrier resin. The filter medium enables organic molecular aerosol which cannot be trapped by a conventional efficient filter layer to be quickly adsorbed by active carbon grains of nano carbon fiber, has the properties of tolerating water washing and holding carbon grains, and can be combined and used with various efficient filter media calendared by other materials. In addition, the filter can be placed in the sun or under an ultraviolet lamp to perform illumination and regeneration after adsorbed saturation, and the service life of the whole filter can be greatly prolonged.
