Description
Technical field
The utility model relates to air purifier, is specially a kind of vertical light catalytic air purifier.
Background technology
China is the more serious country of atmosphere pollution in the world, and the air pollution in city is especially serious.Dust, formaldehyde, benzene, sulfide, ammonia, nitrogen oxide, TVOC severe overweight, the serious harm health.Traditional negative ion air-cleaner, in fact can only reach the effect of " pure and fresh " air, and most of pollutant can't be eliminated; Traditional absorbent-type air purifier is subject to adsorbing saturated restriction, can only dedusting, smoke abatement, eliminate the unusual smell, except formaldehyde, can not remove mycotic spore, virus or bacterium.In addition, from structure, the air inlet/outlet mode of common air purifier be air inlet in the body front, air outlet is at the body upside, this structure is more single.
Summary of the invention
The utility model, for the problems referred to above that the air purifier solved in the market exists, provides a kind of vertical light catalytic air purifier.
The utility model is to adopt following technical scheme to realize:
A kind of vertical light catalytic air purifier, comprise body and thick effect filter screen back shroud (as air inlet), and the back end face of described body is provided with the curved surface exhaust passage of opening upwards, and the below that is positioned at the curved surface exhaust passage in described body is equipped with blower fan; Described thick effect filter screen back shroud be installed on body the side, back and with blower fan over against; Between thick effect filter screen back shroud and blower fan, HEPA filter element, photocatalysis unit are installed successively in body; Described photocatalysis unit comprises framework, and the both sides of described framework are separately installed with dipping TiO
2activated carbon felt, between described two activated carbon felts, several ultraviolet lamp tubes are installed; Distance between described ultraviolet lamp tube surface and activated carbon felt is 4～6mm.
At present, can be numerous as the material of photocatalyst, comprise titanium dioxide (TiO
2), zinc oxide (ZnO), tin oxide (SnO
2), zirconium dioxide (ZrO
2), the many oxide sulfide semiconductors such as cadmium sulfide (CdS), wherein titanium dioxide (Titanium Dioxide) is strong because of its oxidability, and stable chemical nature is nontoxic, becomes in the world the most frequently used nano photo-catalytic material.The utility model photocatalysis air purifying device by titanic oxide impregnation on activated carbon felt, photocatalyst is under the effect of ultraviolet light, electronics on valence band (e-) transits to conduction band, produce corresponding hole (h+) on valence band, generation has superoxide ion free radical, hydroxyl radical free radical, the super oxygen hydroxyl radical free radical of extremely strong oxidation, the oxidation Decomposition such as the toxic and harmfuls such as formaldehyde, benzene,toluene,xylene, ammonia, TVOC, pollutant, foul smell, bacterium can not only be become to harmless CO
2and H
2o, and there is the antiseptic property of high-efficiency broad spectrum, various common pathogenic bacteria are had to good inhibition and killing action.
In the utility model, but photocatalysis unit as a module integrated straight, access out, be convenient to change fluorescent tube and filter core.If internal wiring goes wrong, more can directly change whole photocatalysis unit, avoid the user because maintenance cycle is long, even to need the complete machine maintenance to affect use.Activated carbon felt and related accessory (such as ballast and circuit etc.) that photocatalysis unit comprises several (such as 3) ultraviolet lamp tubes, two dipping photochemical catalysts, the plug stretched out is connected with body, but whole module one is taken out.After photocatalysis unit is taken out, can put into the activated carbon filtration unit of same volume size, become the air purifier of another kind of combination pattern of gas cleaning.
Because exhaust passage is curved surface, after the foul atmosphere that blower fan is drawn into filters by filter element, will make the air-out wind direction transfer eddy flow to upwards, reach maximum with the mitre joint of air intake wind direction, the airflow circulating scope is increased, there is no dead angle.The effect of curved surface exhaust passage is lead and air-out is sealed fully for the air after purifying provides, and guarantees purification efficiency, sends fresh air.By simulation of air flow, test and hydrodynamics calculating, by the air-out Duct design, it is curved surface, do like this and can guarantee that air drag can not increase, can effectively utilize again unnecessary space (can face exhaust passage directly with reference to figure below), filtering layer top, make the clarifier compact overall structure.Exhaust vent is according to aerodynamic design, and the operation range of sounds, between 22～49dB, is used while being conducive to sleep evening.It makes air inlet/outlet more reasonable, and noise is less, and efficiency is higher.
Dirty room air, through the fan effect, by thick effect filter screen, HEPA filter element, photocatalysis unit, is finally sent pure and fresh harmless air from air outlet successively.This process is in indoor continuous circulation, thereby plays the purpose purified the air of a room.Photocatalysis unit is in this process, allow specific wavelength UV-irradiation the dipping titanium dioxide activated carbon felt on, can inspire a kind of to the complete harmless high energy particle of human body, it has extremely strong oxidation-reduction ability, the pollutants such as airborne bacterium, virus, formaldehyde, benzene, dimethylbenzene, ammonia directly can be resolved into to nonpoisonous and tasteless material, thereby reach comprehensive purification, the effect of sterilization, and so complicated structure is integrated on a framework in photocatalysis unit, can wholely takes out and be changed again.When indoor firm finishing, can be removed by selective light catalyst unit PARA FORMALDEHYDE PRILLS(91,95), the user also can select voluntarily, it is replaced by the active carbon unit and obtains different clean-up effects.
The utility model is reasonable in design, simple in structure, at present domestically leading purification techniques-light catalytic purifying technology and HEPA high-efficient purification technology are combined cleverly, photocatalyst can by the bacterium remains and in vivo residual toxin decompose that (general antiseptic only has bactericidal action fully, but can not divide toxolysin), reach the purpose of thorough disinfection sterilization, and in the photocatalyst mechanism, itself does not change and loss, a reacting environment only is provided, it is lasting to have the time, stable in properties, the advantage of safety non-toxic, do not produce secondary pollution, it is the free of contamination product of internationally recognized environmental protection, dust granules in filtered air decompose airborne pernicious gas effectively, thereby reach the purpose purified air.
