Description
Technical field
The present invention relates to a kind of vertical indoor air cleaners of photochemical catalytic oxidation.
Background technology
People's spends at least over the time of half indoors in life, since the interior space is effective, with outdoor
Space exchange less, indoor environment itself is not only without natural purifying ability, but also due to uses such as indoor dress drills, air conditioners
Universal and daily life, constantly polluter is discharged to the interior space, wherein mainly volatility is organic
Object, solid suspended particles and aerosol etc., wherein main pollutant includes formaldehyde and benzene homologues, these polluters are deposited
It is not only making one to generate bad feeling, but also affect the health of people, therefore with the improvement of people ' s living standards
With the aggravation of air pollution degree, air pollution problem inside rooms increasingly get more and more people's extensive concerning.Currently, Interior Space
The method of gas purification is at present both at home and abroad mainly using simple mechanical absorption type, electrostatic, chemical (or physics) absorption type, anion
Formula and photocatalysis formula etc. are mainly used for since simple Mechanical Adsorption and electrostatic precipitation are limited for the effect of air purification
The particulate matter to suspend is removed, it is not high for the degree of purification of organic contamination, therefore be gradually eliminated.And other several technologies
Under product also respectively have advantage and disadvantage, be separately adapted to different pollutant purifications and different customer requirements, such as absorption type is net
Change the characteristics of device is according to selected sorbing material, specific even majority of organic pollutants can be adsorbed, but there are sorbing materials
Saturation problem, need the regeneration and replacement that carry out material, it is stifled due to particulate matter for the higher occasion of particle concentration
Plug, will influence the adsorption capacity of sorbing material, and anion is conducive to the decomposition of organic matter, is allowed to be formed substantially harmless dioxy
Change carbon, water and other inorganic matters, and also there is certain effect with fresh air, helps to improve the quality of air and comfortable
Degree, but the product in reaction process also to a certain extent has adverse effect on human body, it is dirty to bacterial virus and chemistry
The control ability for contaminating object is also very limited；In the past few years, a kind of technology of fast development is built upon on the basis of nano-photocatalyst
Photocatalysis purifying technology, by the catalytic action of nano-photocatalyst, under the ultraviolet light even irradiation of natural light, for having
Machine pollutant is decomposed, and has preferable bactericidal effect, but due to specifically still having office as a kind of unit process
Sex-limited, such as purification efficiency is relatively low, removal pollutant ability is limited when practical application.Therefore, it is necessary to according to growing
Living standard does not turn off and sends out that new function is more, effect is more preferable, production cost is lower, using more easily product, to meet
The needs of people.
Invention content
To overcome the drawbacks described above of the prior art, the present invention provides a kind of purifications of the vertical indoor air of photochemical catalytic oxidation
Device, this clarifier can eliminate the various major pollutants in room air, and this clarifier is simple in structure, and it is convenient to adapt to,
Good purification.
The present invention realizes that the technical solution of above-mentioned purpose is：A kind of vertical indoor air cleaner of photochemical catalytic oxidation, packet
Include shell, be divided into filter chamber, light-catalyzed reaction room and adsorption chamber in shell from bottom to top, be equipped in the filter chamber by
Thin multistage filtering layer is slightly arrived, is equal pressure chamber below the multistage filtering layer, photocatalysis is equipped in the light-catalyzed reaction room
Ultraviolet lamp is equipped with if being equipped with dried layer photochemical catalyst strainer above and below the photocatalysis ultraviolet lamp in the adsorption chamber
Adsorption layer, the shell upper top are equipped with air outlet, and lower side is equipped with air inlet, and the air inlet is connected to the multistage mistake
The lower section of filtering layer.
The beneficial effects of the invention are as follows：Air enters from air inlet in shell, is filtered out after multistage filtering layer wherein
Grain object, then air stream continue to move up, when by each layer photocatalysis filter screen, on strainer photochemical catalyst collide, wherein
Volatile organic gases molecule reacted with the OH on photochemical catalyst after be gradually decomposed into harmless or substantially harmless inorganic matter, then
Air stream enters adsorption layer, and remaining volatile organic gases molecule is adsorbed, after these purified treatments, the air of purification
It is flowed out from air outlet.
Since the present invention has first been equipped with filter layer, the particulate matter in air is filtered out, and its filtering is from thick to thin
Multistage filtering, good filtration effect is conducive to extend the adaptation service life of filtering material, and also avoids particulate matter to subsequent processing
The harm of process；Due to have passed through light-catalyzed reaction so that the volatile organic gases molecule in air is decomposed, and comprehensively disappears
Except various volatile organic gases so that the pollutant concentration into the residual volatile organic gas of adsorption chamber substantially reduces,
It needs the pollutant quality adsorbed few, therefore the service life of sorbing material is greatly improved, avoid and inhaled because frequently more preferable
Trouble and expense caused by enclosure material.
