Description
Technical field
But the utility model relates to the nanometer photocatalytic air purifying device that a kind of fast purification that adopts nano photo catalyzed oxidation decomposes airborne dusty gas and kills airborne bacterium, virus.
Background technology
The air quality in the existing 40% above city of China has reached slight pollution at present, the degree of general room air pollution exceeds outdoor far away, and the public has often ignored the harm of room air pollution to human body when being concerned about the outdoor air quality, in the closed room of using air-conditioning and heating installation, air pollution degree can reach outdoor 5 times to tens times especially.
The indoor pollution source mainly from indoor decoration and mankind itself, daily life produce as formaldehyde, hydrogen sulfide, ammonia, VOC (VOC) gas pollutant of etc.ing and as microorgranic contaminants such as bacterium, viruses.Wherein formaldehyde is a kind of colourless easily molten irritative gas, is defined as suspicious carcinogenic and cause the fetal anomaly material by the World Health Organization.Present multiple artificial board, adhesive, wallpaper etc. all contain formaldehyde, and the release period of formaldehyde reaches 3 to 15 years.Calendar year 2001, the investigation result of Chinese Consumers' Association showed in the indoor environment at the seventy percent above new home that toxic gas such as formaldehyde exceeds standard.
Nano photo catalyzed oxidation is the two combination of nanometer technology and photocatalysis technology.The photochemical catalyst that with titanium dioxide is representative is described as " environmental catalysts ", under ultraviolet irradiation, they can make at normal temperatures and pressures, and formaldehyde etc. is harmful to have flavor gas to resolve into harmless tasteless substance, and this is a kind of chemical breakdown but not simple physical absorption, can not produce secondary pollution, this does not consume photochemical catalyst in course of reaction, is a kind of desirable air purification and sterilizing material therefore.Because nano material has characteristics and quantum size effects such as surface area is big, the active height of surface atom,, therefore adopt the nano photo catalyzed oxidation of nano-photocatalyst to have more efficient simultaneously so have higher catalytic activity.
Chinese patent 99221661.3 discloses a kind of " air cleaning filter screen ", as shown in Figure 1, cover photochemical catalyst (2 ') on the surface that is cellular carrier (1 ') that it is characterized in that making by any material in aluminium foil, plastics, foam, felted nonwoven, the paper etc., and all surfaces that can contact on the carrier with air, comprise all through hole 1 '-1 on the carrier ' interior sidewall surface all to be covered by photochemical catalyst.Although this air cleaning filter screen has bigger surface area, but when gas during by the air cleaning filter screen, the photochemical catalyst that has only the interior sidewall surface of its through hole contacts with air and brings into play catharsis, and other surperficial photochemical catalyst is because little with the gas touch opportunity, and its light catalytic purifying effect is also very limited.Because photochemical catalyst 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 provide a kind of to adopt grid-like carrier that surface preparation has transparent porous photocatalysis film as the photocatalysis parts, has the nanometer photocatalytic air purifying device of very high air cleaning decomposition efficiency.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the nanometer photocatalytic air purifying device, include interconnected shell and control panel with air inlet, air outlet, be built in shell and control panel over against air inlet fixing axial flow blower, guide duct arranged, at least 1 pair of nano-photocatalyst assembly is installed above axial flow blower and the ultraviolet lamp bracket of uviol lamp is installed, it is characterized in that described nano-photocatalyst assembly is made up of at the transparent porous nanometer photocatalyst film on its surface with preparation the carrier of gridiron; Ultraviolet lamp bracket serial connection is stacked between 1 pair of nano-photocatalyst assembly upper and lower; At 1 pair of nano-photocatalyst assembly upper and lower serial connection closed assembly reflective filter aerofoil is arranged simultaneously.
Described ultraviolet lamp bracket profile is cuboid, parallel in lamp bracket several uviol lamps is installed, and lamp bracket inwall surrounded surface posts reflective material layer.
Described reflective filter aerofoil profile is a flat cuboid, is subjected to (descending) surface of going up of light to post reflective material layer, its interior parallel oblique filter air port that is louvered that is distributed with.
Described nano-photocatalyst assembly and ultraviolet lamp bracket can be provided with 2-5 serial connection is arranged.
The utility model compared with prior art, owing to adopted 1 pair of surface preparation with huge surface area that the grid-like nano-photocatalyst assembly of nanometer photocatalyst film is arranged, ultraviolet lamp bracket in the middle of being positioned at makes all photocatalyst film surfaces all be subjected to ultraviolet irradiation, therefore all has the ability of decomposing dusty gas that purifies, and the inwall of ultraviolet lamp bracket, the sensitive surface of the reflective filter aerofoil of louvered all posts reflective material layer up and down, further increased the uitraviolet intensity on photocatalyst film surface, thereby further improved its purification decomposition efficiency dusty gas.For nanometer photocatalyst film, dusty gas not only can contact with the nano particle of nano-photo catalytic film surface and be cleaned decomposition, but also porous is cleaned decomposition to inner the contact with the nano particle of internal layer of nano-photo catalytic film.Bond strength between nano-photo catalytic film and the carrier material is quite high in addition, has only with carborundum cloth and film destruction could have been improved the life-span of nano-photo catalytic accessory greatly.
