Therefore, purifying efficiency of the photocatalysis air purifier is improved.
Description
Technical field
The present invention relates to air cleaning unit, particularly relate to a kind of three-dimensional photocatalysis air purifying device.
Background technology
In contemporary society, people improve constantly the requirement of quality of life.In recent years, people are also more and more higher to the comfortable and requirement attractive in appearance of house, often spend great effort and money decorating house, and towards fine fitment, excessive trend development of decorateing.Along with the stickup of a large amount of made various finishing materials puts in place, the organic pollution being much present in various building materials also becomes the pollutant of room air thereupon.At present, due to when producing ornament materials and wood-based plate in technology and technique mostly with an organic solvent as additive, make the pollution that is inevitably subject to little molecule volatile organic matter indoor.In the redecorated house indoor air of major part, take the indoor environmental pollution thing severe overweight that formaldehyde, benzene homologues etc. are representative, occupant's health has been caused to grievous injury.
There is data to show, Wenzhou City's quality technical supervision detects institute and within 2009, accepts 102 families trust new house room airs detection formaldehyde, benzene,toluene,xylene, TVOCs, found that in 82 family new houses, air quality is defective, qualification rate is only 19.61%; Within 2010, accept 167 families and entrust new house room air to detect, found that in 142 family new houses, air quality is defective, qualification rate is only 14.97%.As can be seen from the above data, air quality is defective has caused huge injury to human body, air pollution harm has covered our all households, working environment, serious harm health, especially particularly serious to the old,weak,sick and disabled's harm, it is particularly important that the pollution control of room air seems.This will ask for help must take degraded measure accordingly to reduce the harm that Formaldehyde Pollution of Indoor Air causes health.Because the release of indoor air pollutants has persistence and probabilistic feature, therefore using air purifier to purify the air of a room is the internationally recognized method of improving IAQ.
Conventional air purifying process has: the asymmetric plasma air purifying technology of low temperature, adsorption technology, anion technology, negative oxygen ion technology, molecular complex technology, photocatalyst technology, HEPA high efficiency filter technology, electrostatic precipitation technology, active oxygen technology etc.; Material technology mainly contains: photocatalyst, active carbon, synthetic fibers, the efficient material of HEAP, anion generator etc.The existing air purifier of domestic market is adopted as compound more, has adopted multiple purification techniques and material medium simultaneously.Chemistry is mainly used in removing with physical absorption and electrostatic precipitation the particle suspending in air, limited to the removal effect of organic pollution and bacterium.Although anion is decomposing organic matter to a certain extent, the problem of harmful side product that thoroughly do not produce easily occurs to decompose, and it does not have the function of sterilization, limited to air purification effect.And the effect of current Photocatalyst aspect sterilization and degraded VOC is better, be subject to the consistent favorable comment of all circles.
Notification number is that the Chinese patent of CN2747497Y discloses a kind of vertical light catalytic air purifier, this clarifier comprises casing, the bottom of casing is provided with air inlet, elementary filter screen, axial-flow fan, blower motor and distinguished and admirable guiding spiral case, the top of casing is provided with air outlet, in addition, in casing on spiral case top, horizontal by the middle screen pack that is less than 90 ° of inclination angles; On the upper surface of spiral case, be also provided with deflector, the top of deflector is provided with photocatalysis unit, and photocatalysis unit is comprised of catalyzed honeycomb net and uviol lamp.During use, in axial-flow fan is introduced casing by the air in external environment from air inlet, enter air in casing first successively through elementary filter screen, deflector and middle screen pack dedusting, then through photocatalysis unit, purify, finally by air outlet, discharged.In above-mentioned clarifier, owing to having adopted catalyzed honeycomb filter structure, therefore increased the contact area of distribution area and air and the catalyst of catalyst, thereby improved to a certain extent the purification efficiency of clarifier.But, that adopt due to its catalyzed honeycomb filter screen is a kind of in aluminium, paper, pottery, plastics, fiber and nonwoven cloth material, therefore, it is only the carrier use as photochemical catalyst, the materials such as the organic matter particulate being mingled with in air do not have the effect of initiatively holding back, this causes the time of contact of airborne harmful substance and catalyst extremely short, be difficult to it degradable, thereby cause the problem of secondary pollution; In addition, owing to being the mode that adopts forced air inlet, the air entering in casing is difficult to distribute uniformly and contact with catalyst, this is also a reason that affects clarifier efficiency, moreover above-mentioned clarifier time must be usingd power supply as the energy in work, indoor need normalization to purify air in the situation that nowadays, the clarifier that need work long hours will certainly expend a large amount of electric energy, and this has increased the cost purifying air.
Summary of the invention
The object of the present invention is to provide a kind of three-dimensional photocatalysis air purifying device, to improve the purification efficiency of photocatalysis air purifying device.
In order to address the above problem, three-dimensional photocatalysis air purifying device of the present invention is by the following technical solutions: three-dimensional photocatalysis air purifying device, comprise housing, housing has described in air inlet, air outlet and connection into and out of air cleaning passage air port, enclosed, in air cleaning passage, be provided with at least one-level photocatalysis assembly, described photocatalysis assembly comprises catalyst plates, and catalyst plates is provided with photochemical catalyst, and described catalyst plates is adsorptivity orifice plate.
The adsorptivity orifice plate of described catalyst plates for being formed by graphite orifice plate.
Described housing is transparent shell.
Described housing is glass shell.
