Description
Technical field
The present invention relates to a kind of vertical indoor air cleaner of photochemical catalytic oxidation.
Background technology
People's the time that surpasses half is in life at least spent indoor, because the interior space is effective, less with outdoor space exchange, indoor environment itself does not only have natural purifying ability, and owing to indoor dress is drilled, what air-conditioner etc. used popularizes and daily life, constantly discharging polluter to the interior space, it wherein mainly is volatile organic matter, solid suspended particles and aerosol etc., wherein main pollutant comprise formaldehyde and benzene series thing, the existence of these polluters, not only make the people produce bad sensation, but also affect the healthy of people, therefore along with the raising of people's living standard and the aggravation of air pollution degree, the room air pollution problem more and more gets more and more people's extensive concerning.At present, main both at home and abroad at present simple mechanical adsorption-type, electrostatic, chemical (or physics) adsorption-type, anion formula and the photocatalysis formula etc. of adopting of the method for indoor air purification, because absorption of simple machinery and electrostatic precipitation are limited for the effect of air cleaning, mainly be to be used to remove the particles suspended thing, degree of purification for organic contamination is not high, therefore is eliminated gradually.And the product under other several technology also respectively has pluses and minuses, be adapted to different pollutant purifications and different customer requirements respectively, for example the adsorption cleaning device is according to the characteristics of selected adsorbing material, can adsorb specific even majority of organic pollutants, but the saturation problem that has adsorbing material, need carry out the regeneration and the replacing of material, for the higher occasion of particle concentration, because the obstruction of particulate matter, the absorbability of adsorbing material will be influenced, and anion helps organic decomposition, make it to form harmless substantially carbon dioxide, water and other inorganic matters, and have certain effect with fresh air, help to improve the quality and the comfort level of air, but the product in the course of reaction also produces adverse influence to human body to a certain extent, and its control ability to bacterial virus and chemical pollutant is also very limited; In the past few years, a kind of technology of fast development is the light catalytic purifying technology that is based upon on the nano-photocatalyst basis, catalytic action by nano-photocatalyst, under the irradiation of ultraviolet even natural light, decompose for organic pollution, and have bactericidal action preferably, but owing to specifically as a kind of unit process limitation is arranged still, for example purification efficiency is lower, and it is limited in one's ability to remove pollutant during practical application.Therefore, need be according to growing living standard, continually develop that the function that makes new advances is more, better effects if, production cost are lower, use product more easily, to satisfy people's needs.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of vertical indoor air cleaner of photochemical catalytic oxidation, this depurator can decontamination chamber in airborne various major pollutants, this depurator is simple in structure, it is convenient to adapt to, good purification.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of vertical indoor air cleaner of photochemical catalytic oxidation, comprise housing, be divided into the filter chamber in its housing from bottom to top successively, light-catalyzed reaction chamber and adsorption chamber, be provided with multistage filtering layer from coarse to fine in the described filter chamber, the below of described multistage filtering floor is all to press the chamber, the indoor photocatalysis uviol lamp that is provided with of described light-catalyzed reaction, the above and below of described photocatalysis uviol lamp is equipped with several layers photocatalyst filter screen, be provided with adsorption layer in the described adsorption chamber, described housing upper top is provided with air outlet, lower side is provided with air inlet, and described air inlet is connected in the below of described multistage filtering layer.
The invention has the beneficial effects as follows: air is in air inlet enters housing, remove wherein particulate matter through multistage filtering layer after-filtration, air flow continues to move up then, during through each layer photocatalysis filter screen, with the photocatalyst collision on the filter screen, be decomposed into harmless or harmless substantially inorganic matter gradually after volatile organic gas molecule wherein and the reaction of the .OH on the photocatalyst, air flow enters adsorption layer then, remaining volatile organic gas molecule is adsorbed, through after these purified treatment, the air of purification flows out from air outlet.
Because the present invention has been provided with filter course earlier, with airborne particulate matter filtering, and its filtration is multistage filtering from coarse to fine, and good filtration effect helps prolonging the adaptation life-span of filtering material, and has avoided the harm of particulate matter to subsequent processes; Owing to passed through light-catalyzed reaction, make airborne volatile organic gas molecule be decomposed, comprehensively eliminate various volatile organic gas, the feasible pollutant levels that enter the residual volatile organic gas of adsorption chamber reduce greatly, need the adsorbed contaminants quality few, therefore increase substantially the service life of adsorbing material, avoided trouble and the expense brought because of frequent better adsorbing material.
