Description
Technical field
This utility model relates to a kind of air purification and sterilizing accessory that adopts nano photo catalyzed oxidation, especially adopts to have the catalysis technique of the froth bed of tridimensional network as the carrier of nanometer photocatalyst film.
Background technology
The present carrier of photocatalyst that generally uses in air purification field, generally be to use the cellular carrier that is that any material in paper or aluminium foil, plastics, foam, the felted non-woven fabrics etc. makes, utilize adhesive that photocatalyst is fixed in the surface, the limit irradiation ultraviolet radiation, the limit allows air pass through, to decompose, to remove harmful gas (JP0801010, Chinese patent 99116885.2,99221661.3).The air of this technology is that piston flow passes through alveolate texture, therefore has harmful substance and the lower problem of photocatalyst contact probability in the air.Because photocatalyst is to adopt the spraying coating process preparation, the bond strength of this coating and base material is not high, thereby reduces the service life of coating simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and provides a kind of and adopts that specific surface area is big, porosity is high, the aperture is little, have the structure sheaf of tridimensional network as carrier material, and preparation has transparent porous nanometer photocatalyst film thereon, makes it have very high contaminated air is purified and decomposes germ-resistant air cleaning accessory.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: the nanometer photocatalytic air purifying accessory, several ultraviolet germicidals that are arranged in parallel are installed in the enclosure, be installed on the ultraviolet germicidal, the preparation of downside has the layered vector of transparent porous nanometer photocatalyst film, the fixedly reflectorized material pasted of the outer casing inner wall of ultraviolet germicidal and the attaching plug that links to each other with ultraviolet germicidal, it is characterized in that it is the structure sheaf with tridimensional network that described preparation has the layered vector of nanometer photocatalyst film, simultaneously on this carrier, be provided with adsorption layer below.
Described structure sheaf carrier is made up of the 2-6 layer, with ultraviolet germicidal alternately.
Described structure sheaf carrier can be foam metal layer or foamed ceramics layer or foam glass layer.
Described foam metal layer can be nickel foam or foam copper or foamed aluminium.
Described adsorption layer can be active carbon fiber felt or activated carbon foam felt or activated carbon gum sprayed cotton felt.
Described nanometer photocatalyst film is the nm TiO 2-base optical catalyst thin film.
Compared with prior art, this utility model is owing to adopted the structure sheaf with tridimensional network as the carrier for preparing nano-photocatalyst, its specific surface area is big, the porosity height, the aperture is little, contaminated air will not be laminar flow, piston flow passes through, but sinuous flow passes through, therefore can fully contact with the nanometer photocatalyst film of preparation at its all surface, and can prepare a large amount of nanometer photocatalyst films, and bond strength is quite high, and air flow is connected with abundant space, its aperture is small, so the contacting efficiency of contaminated air and photocatalyst is just high; The setting of the upper and lower adsorption layer of carrier not only has dedusting function, and the irradiation that can adsorb simultaneously harmful gas and the ultraviolet light by seeing through carrier layer is decomposed it, so have very high purification decomposition germicidal efficiency and nano-photocatalyst carrier life.

The specific embodiment
Embodiment describes in further detail this utility model below in conjunction with accompanying drawing.
Referring to Fig. 1-3, the nanometer photocatalytic air purifying accessory has one neither to bind and the shell 4 of back cover not, make contaminated air from bottom to top direction see through, shown in the arrow of Fig. 2, Fig. 3.Be provided with fixed upper and lower adsorption layer 1 in the shell, adsorption layer is any one in active carbon fiber felt or activated carbon foam or the activated carbon gum sprayed cotton felt, both can be used for dedusting, also can be used for adsorbing the gaseous matter and the harmful gas of difficult purification decomposition such as smog, but the ultraviolet light of nationality by the nano-photo catalytic agent carrier also simultaneously makes the harmful gas of absorption decompose and regenerate.
Described preparation has the layered vector 2 of transparent porous nanometer photocatalyst film to be foam metal material, and this carrier has tridimensional network, and its specific surface area is big, and porosity is 55-95%, and the aperture is 60-120PPI, and surface density is 300-700g/m
2, making with the nanometer photocatalyst film for preparing thereon can have sufficient the contact, the contacting efficiency height, make ventilating air that sufficient space be arranged, contaminated air will not be laminar flow, piston flow passes through, but sinuous flow passes through, thereby has very high nanometer photocatalytic air purifying decomposition efficiency.
Preparing transparent porous nanometer photocatalyst film is to adopt the preparation technology of development voluntarily supporting a kind of nm TiO 2-base photocatalysis film that material surface directly is prepared from, and has very high air purification and sterilizing efficient.Thin film is made up of the nano-particle of uniformity, and its granular size is evenly distributed with a large amount of nano-pores between the nano-particle below 100nm, and its aperture is generally tens to hundreds of nanometers, promptly a kind of porous nano thin-film.This nano-catalytic agent film not only has very strong purification capacity of decomposition to contaminated air, but also has antibiotic, sterilizing function, promptly has very strong air purification and sterilizing ability, contaminated air not only is cleaned decomposition, is cleaned decomposition but also may penetrate in the nano-particle of nano-photo catalytic film internal layer.Since preparation process be not by binding agent with specific technology at a certain temperature sintering be prepared from, make and have very high bond strength between nano-photo catalytic thin film and the carrier, have only with carborundum cloth and could destroy thin film, improved the life-span of nano-photo catalytic agent carrier greatly.
Between the described ultraviolet germicidal that is arranged in parallel 3, the alternate layered vector 2 that is located at upper and lower nanometer photocatalyst film, its optical source wavelength adopts the 200-300nm scope, and dominant wavelength is about 254nm.Not only comparable employing wavelength improves the efficient of nanometer photocatalytic purification dusty gas at uviol lamp or the wavelength of 300-400nm at the visible light source of 400-700nm, and can kill airborne antibacterial, virus effectively.And the reflective material layer 5 that outer casing inner wall is pasted more helps ultraviolet light and shines more on the carrier, also is one of reason that improves nanometer photocatalytic air purifying efficient.Ultraviolet germicidal has independently electric appliance circuits, links to each other with power supply by line trap 6.
