Abstract
A titanium dioxide light catalytic air purifier which uses nanometer TiO2 to purify air is composed of a casing, a fan and a purifying core. An air inlet and an air outlet are equipped on the casing. The purifying core is equipped in the casing and between the air inlet and the air outlet. The fan is equipped at an air inlet end of the casing. The titanium dioxide light catalytic air purifier is characterized in that: the purifying core is a cylindrical honeycomb ceramic and TiO2 is loaded in the holes of the cylindrical honeycomb ceramic; ultraviolet source is equipped on the shaft line in the cylindrical honeycomb ceramic; ultraviolet source is equipped on the shaft line of the cylindrical foamed ceramic loaded with nanometer TiO2 to make the ultraviolet light strength which is irradiated on the cylindrical honeycomb ceramic be the same; the air can be purified uniformly without a purifying blind angle; because the area of the foamed ceramic is bigger than the superficial area, the contact area of air and nanometer TiO 2 is big to further strengthen the light catalytic reaction.
Description
Technical field
The utility model relates to a kind of purifier that enclosure space is removed airborne organic pollution such as be used in indoor, the car, relates in particular to a kind of nano-TiO of using
2The titanium dioxide photocatalysis air-cleaning device that purifies air.
Background technology
People's most of the time in all one's life is spent indoor, along with the raising day by day of living standard, the degree of dependence of the vehicles is also increased, and the time in car also increases.Scientists is found after deliberation, is growing various bacteria, mould in air conditioner and the carpet and is plucking worm, is attached on the dust granule with the air borne disease; The paint that interior trim is used, coating, sheet, harmful chemical fibre thing constantly give out poisonous and harmful organic gas and carcinogens such as formaldehyde, benzene; The ammonia flavor in harmful substance that human body self produced and bath lavatory is polluted the air in the enclosure space.Contaminated air can cause people spirit ginger to waste depressed, inefficiency in these enclosure spaces, even the incidence of disease of malignant tumour such as lung cancer is also relevant with these pollutions.
Studies show that these materials that pollute IAQ mainly are chemical substances, and formaldehyde, benzene, dimethylbenzene, ammonia, CO, CO are arranged
2, NO
x, SO
2And other VOC (VOC) etc.The characteristics of air pollutants are complicated components in the enclosure space of mankind's activity, and the concentration of pollutant is low, and the time that acts on human body is long, and is very big to the health hazard of human body.
For many years, people have entered unremitting effort for finding solution to the problems described above, successively develop in mechanical filtering type, electronic dust-collecting type, the anion and the air purification method and the device thereof of kind such as formula.Yet these methods only to some harmful substance generation effect of room air pollution, can not be dealt with problems fully, and easily produce secondary pollution.
Utilizing the airborne organic nuisance of photocatalytic degradation is the preferred plan of generally acknowledging at present, and nano-TiO
2Be the best catalyst of light-catalyzed reaction, it is so that it is inexpensive, nontoxic, catalytic activity is high, oxidability is strong, good stability and being widely used.Studies show that nano-TiO
2The photocatalysis characteristic of photocatalyst material has broad spectrum activity, almost all pollutants is all had Governance Ability, can be at normal temperatures effective airborne light concentration organic pollutant in the decomposition chamber, the airborne NO of oxidation removal
x, H
2S, VOC (VOC) and all kinds of foul smell can also be eliminated airborne bacterium and virus.Light catalytic purifying reaction condition gentleness in addition, the technology applying flexible is convenient, enclosure space such as can be applicable in indoor, the car and removes airborne organic pollution.
Summary of the invention
The utility model provides a kind of and can evenly purify and titanium dioxide photocatalysis air-cleaning device that can strengthened purification air.
The utility model adopts following technical scheme to solve its technical problem:
A kind of use nano-TiO
2The titanium dioxide photocatalysis air-cleaning device that purifies air, form by housing, fan and purification core body, on housing, be provided with air intlet and air outlet slit, purifying core body is located in the housing and between air intlet and air outlet slit, fan is located at the air inlet end of housing, purify core body and be the cylindrical shape porous ceramics and in the hole of cylindrical shape porous ceramics load TiO is arranged
2, be provided with ultraviolet source on the axial location in the cylindrical shape porous ceramics.
Compared with prior art, the utlity model has following advantage:
1) ultraviolet source is positioned at cylindrical shape loaded with nano TiO
2On the axis of foamed ceramics, make that the ultraviolet ray intensity that shines on the cylindrical shape porous ceramics is all identical, thereby the purification of air is carried out equably, avoided purifying the generation at dead angle.
2) because the foamed ceramics specific area is big, air and nano-TiO
2Contact area big, light-catalyzed reaction is further strengthened,
3) air prolongs its time of staying in clarifier by certain thickness foamed ceramics.
4) wind speed is regulated with adjustable plate at the clean air outlet place, strengthened clarifier and discharge the disturbance of gas, improve the convection intensity of enclosure space air, help improving purification efficiency air.
