Title: AIR DISINFECTION PURIFIER AND METHOD FOR PREPARING PHOTOCATALYTIC FILM USED THEREBY
Abstract:
An air disinfection purifier, comprising an outer shell (1), a centrifugal device (2), a filtration device (3) and a photocatalytic device (4), wherein the centrifugal device (2), the filtration device (3) and the photocatalytic device (4) are located inside the outer shell (1); the photocatalytic device (4) is located on the inner side of the filtration device (3); the centrifugal device (2) is located above the filtration device (3) and the photocatalytic device (4); the outer shell (1) is provided with an air inlet (11) and an air outlet (12); the photocatalytic device (4) comprises a light source (41) and a photocatalytic film (42), and the light source (41) is located inside the photocatalytic film (42); and the photocatalytic film (42) comprises a substrate layer (421), a three-dimensional graphene layer (422), a TiO2 nano-film layer (423) and a nano-silver layer (424), the three-dimensional graphene layer (422) is located between the substrate layer (421) and the TiO2 nano-film layer (423), and the nano-silver layer (424) is located on the TiO2 nano-film layer (423). In the device, the photocatalytic efficiency of the TiO2 nano-film layer is enhanced by means of the characteristics of the three-dimensional graphene layer, harmful gases in the air can be effectively removed, and harmful bacteria in the air can be killed.
