Visible light photo-catalytic air purifying filter

Abstract

The invention discloses a visible light photo-catalytic air purifying filter which comprises an air inlet and an air outlet, wherein a front de-dusting module, an air filtering module, an air blower and a rear de-dusting module are successively arranged between the air inlet and the air outlet; the air filtering module comprises an LED (Light Emitting Diode) lamp and a plurality of graphene fiber layers; visible light photo-catalytic coatings are loaded on the graphene fiber layers. After the visible light photo-catalytic nanometer materials are loaded onto the graphene fibers according to the invention, the air purifying filter has an excellent absorbing function and an excellent visible light photo-catalytic property. When the circulating air passes by the graphene fibers coated with the visible light photo-catalytic nanometer materials, the absorbing function is utilized to absorb and capture the toxic harmful gases in air, and then the captured toxic harmful gases are continuously decomposed into harmless CO2 and H2O under the effect of visible light; the visible light photo-catalytic air purifying filter has the characteristics of automatic removal for the surface air pollutants and self-cleaning function; due to the excellent air purifying effect, the visible light photo-catalytic air purifying filter can be used in a submarine cabin.

Description

technical field [0001] The invention relates to an air purification filter, in particular to a visible light photocatalytic air purification filter. Background technique [0002] The submarine cabin is not only a space for officers and soldiers to work and live for a long time, but also a relatively long-term closed space. Various gases produced by the equipment and materials in the cabin and various substances produced by human metabolism are often enriched here. However, due to the inability to exchange fresh air, the air quality inside the cabin is seriously reduced, and the harmful substances contained in it will threaten or even damage the health of every member. And harmful gas reaches a certain concentration and will pose a threat to the ship. Contents of the invention [0003] In order to overcome the above deficiencies, the present invention provides a visible light photocatalytic air purification filter capable of absorbing and purifying harmful substances in th...
