Abstract

The present invention discloses a photocatalyst air purifier which uses nanometer TiO2 to purify the air. The present invention comprises a casing, a fan and a purifying core, wherein an air inlet and an air outlet are arranged on the casing; the purifying core is arranged in the casing and positioned between the air inlet and the air outlet; the fan is arranged at the air admission end of the casing. The present invention is characterized in that the purifying core is cylindrical porous ceramics, and TiO2 is loaded in holes of the cylindrical porous ceramics; an ultraviolet light source is arranged in the position of a shaft line in the cylindrical porous ceramics, wherein the ultraviolet light source is positioned on a shaft line of cylindrical foamed ceramics loaded with nanometer TiO2 to make the strength of ultraviolet light irradiating on the cylindrical porous ceramics identical, so that the purification of the air can be carried out uniformly, and the generation of purification dead angles is avoided; because the specific surface area of the foamed ceramics is large, the contact area of the air and the nanometer TiO2 is large, and the photocatalyst reaction is further enhanced.

Description

Photo-catalytic air cleaner
Technical field
The present invention relates to a kind of purifier that enclosure space is removed airborne organic pollution such as be used in indoor, the car, relate in particular to a kind of nano-TiO of using 2The photo-catalytic air cleaner 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 invention provides a kind of can evenly the purification and photo-catalytic air cleaner that can strengthened purification to air.
The present invention adopts following technical scheme to solve its technical problem:
A kind of use nano-TiO 2The photo-catalytic air cleaner 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 present invention 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.

Fig. 2 is a structure vertical view of the present invention.
The specific embodiment
A kind of use nano-TiO 2The photo-catalytic air cleaner that purifies air, form by housing 4, fan 2 and purification core body 5, on housing 4, be provided with air intlet and air outlet slit, purifying core body 5 is located in the housing 4 and between air intlet and air outlet slit, fan 2 is located at the air inlet end of housing 4, purify core body 5 for the cylindrical shape porous ceramics and in the hole of cylindrical shape porous ceramics load TiO is arranged 2Be provided with ultraviolet source 6 on the axial location in the cylindrical shape porous ceramics, air intlet place at housing 4 is provided with screen pack 1, in housing 4 and between fan 2 and purification core body 5, be provided with air volume distributor 3, this air volume distributor 3 is made up of one group of grid, to impel air equably by purifying core body.
When the present invention used, air is under the driving of fan 2, and was through entering purifier shell 4 after filter screen 1 filtration, even by load TiO after air volume distributor 3 is regulated 2Foamed ceramics 5 decomposes airborne organic pollution under ultraviolet source 6 irradiations, and the air after the processing is discharged from the exit.In the present embodiment, housing 4 adopts shedding shell, opening part at shedding shell is provided with cover plate 9, ultraviolet source 6 usefulness lamp sockets are fixed on shedding shell and the cover plate 9, and the cylindrical shape porous ceramics is fixing by cover plate 9 and purifier shell 4, and damping sealing gasket 8 is set in the contact site, to improve the anti-seismic performance of device, outlet regulating plate 10 is equipped with at air outlet slit place after processing, and the speed of discharging gas is regulated.
