Abstract
The utility model relates to a nanophase multiplex air purificant which belongs to the field of air purification. The purificant comprises a photocatalyst (1), wherein the photocatalyst (1) is prepared from 10-30 nm titanium dioxide nanophase material. The nanophase multiplex air purificant has the characteristics of high treatment efficiency and long-term use.
Description
Technical field
This utility model relates to the environmental conservation air purification field; specifically be nuisance in a kind of long-acting lasting decomposition contaminated air such as formaldehyde, benzene, TVOC etc., have the health environment-friendly type air purifying preparation of deodorization taste removal, bactericidal, antitoxin mildew-resistant, hydrophilic self-cleaning simultaneously.
Background technology
The living environment air pollution of mankind nowadays increases day by day.The air pollution of room, office, working space is more and more heavier.Particularly after the house decoration, harmful gass such as the benzene that finishing material discharged, formaldehyde are very serious to people's murder by poisoning.Unwholesome in recent years public place, room air toxic pollutant have caused the global population morbidity and the increase of mortality rate.Its main cause be newly-built and the building materials selected for use of the building rebuild in contain harmful gass such as formaldehyde, benzene series thing, TVOC, and severe overweight causes the air pollution in the indoor environment.And closed stable breeding breed places such as chicken farm, pig farm often stink to high heaven, and air pollution is even more serious.The lighter can influence human body immune system, cause hematopathy and other serious disease, even carcinogenic.In addition, the outbreak of epidemic of bird flu, SARS also causes air pollution, in a word, purifies air, protects environment to become to be badly in need of the key subjects of solution.Though have multiple purified product to come out so far, result of use is all undesirable.
Air cleaning now generally takes to use materials such as activated carbon, silica gel and molecular sieve that dusty gas is adsorbed, particularly use activated carbon products to carry out Filtration Adsorption, perhaps use chemical drugs and harmful gas generation chemical change, as oxidation stain gas such as formaldehyde remover, gram benzene spirit, eliminating smell agent even adopt plant to absorb airborne harmful gas, or carry out biological oxidation, decompose that still effect is unsatisfactory with microorganism, enzyme.
Photocatalyst is a kind of high-tech green technology that development in recent years is got up, it relies on the irradiation of ultraviolet harmonic light to excite catalyst and water reaction to produce strong oxidizer hydroxyl free radical, effectively resolving harmful gas destroys the DNA tissue of virus, pathogenic bacteria in the air, makes it to lose replication capacity.And can destroy the cell wall of antibacterial, and Cytoplasm is run off to dead, reach efficient sterilizing, the effect of the poison that goes out, taste removal, can be widely used in the mankind and fowl dirty swine ever-changing environment.But because that prior art material therefor etc. is selected for use is improper, cause photocatalyst too short time of contact with the air that needs purified treatment, measure also very little, thereby inefficiency, treating capacity is little, effect is still undesirable.
Summary of the invention
But the purpose of this utility model provides the multi-joint air purifying preparation of nanometer of a kind of air cleaning treatment effeciency height and corrosion-resistant life-time service.
The technical solution of the utility model is: the multi-joint air purifying preparation of a kind of nanometer, to form by photocatalyst, and described photocatalyst is made by 10～30nm grade titanium dioxide nano material.
It is that the ultraviolet of 180～380nm wavelength is the resonance light source that this utility model has adopted emission band, and this light source can make 10～30nm grade titanium dioxide produce electron hole pair, thereby can be oxidation operation water and thoroughly pollution abatement of carbon dioxide.The electronic structure of photocatalyst is full valence band and empty conduction band, under illumination condition greater than its band-gap energy, after the photocatalyst absorbing light energy, the valence band center electron will be excited to conduction band, it is right to form electronics (e-) and hole (h+), under effect of electric field, electronics separates with the hole, electronegative electronics combines with oxygen and produces negative bivalence oxonium ion, the positively charged hole combines with water and produces the hydroxyl free radical, when organic material and part inorganic matter touch photocatalyst surface by cross-ventilation, just can be respectively by negative oxygen ion and hydroxyl free radical absorption and oxidation Decomposition, finally be decomposed into carbon dioxide and water (as organic pollution formaldehyde, benzene, dimethylbenzene, toluene, bacterial virus etc., part inorganic pollution ammonia, NOX etc. are broken down into CO
2And H
2O).Utilize this reaction can effectively decompose nuisances such as antibacterial in the live and work space, virus, formaldehyde benzene, ammonia, TVOC, thereby reach the purpose that purifies air.In addition in the light-catalyzed reaction process, sodium titanium rice material has the generation of nano bubble, hindered the secondary light energy and entered sodium titanium rice material reaction center, caused sodium titanium rice to lose efficacy and the regulation effect bounce-back, this phenomenon is called disconnectedization of photocatalysis phenomenon.Therefore we use surface tension to change agent in sodium titanium rice raw material, bubble can't be adhered to, thereby have solved that nano bubble accumulates in sodium titanium rice particle surface in photocatalytic process and the problem that causes photocatalysis performance decline.
As of the present utility model a kind of preferred, be added with binding agent on the described photocatalyst.
Because titanium dioxide is solid, proportion is bigger, can precipitate in water, also can mutually combine between particle.Keep titanium dioxide in water, can not condense, with regard to handling it evenly and is not precipitated through dispersion technology, in addition because the photocatalyst of titanium dioxide raw material certainly will will be fixed on object surfaces, just can receive light and be stimulated, therefore should add binding agent on the photocatalyst, it is fixed on the body surface.
In sum, but air purifying preparation provided by the utility model has the characteristics of treatment effeciency height, corrosion-resistant, easy processing, the low life-time service of cost.
Description of drawings
Accompanying drawing 1 is the structural representation of the multi-joint air purifying preparation of nanometer among the embodiment 1.
The specific embodiment
Embodiment 1
The multi-joint air purifying preparation of a kind of nanometer, form by photocatalyst 1, described photocatalyst 1 is made by 10～30nm grade titanium dioxide nano material, be added with binding agent 2 on the described photocatalyst 1, the light source that is adopted is the ultraviolet of 180～380nm wavelength, because titanium dioxide is solid, proportion is bigger, in water, can precipitate, also can mutually combine between particle, need adopt conventional dispersion technology to handle for this reason to keep titanium dioxide in water, can not condense.
Claims (2)
1. the multi-joint air purifying preparation of nanometer is made up of photocatalyst, it is characterized in that described photocatalyst (1) made by 10～30nm grade titanium dioxide nano material.
