The air disinfection depurator
Technical field
This utility model belongs to air purification field, relates to a kind of air purifier, establishes the air disinfection depurator of cellular activated carbon layer in especially a kind of.
Background technology
In the modern life, automobile and IAQ (indoor air quality) have very significant effects to human beings'health and comfortable life, the good and multiple disease of uncomfortable, healthy mistake that abominable room air can cause; Good IAQ (indoor air quality) can guarantee habitant's comfort and keep good condition of health.The factor that influences IAQ (indoor air quality) is a lot, as temperature, humidity, air mass flow, pollutant kind and content thereof etc.In indoor air pollutants all multifactor, so volatile organic matter (VOCs) the most difficult control and bigger to the harm of human body in recent years, has caused people's attention and attention more and more to the Detection ﹠ Controling of volatile organic matter in the indoor environment.It is relevant with the multiple disease of human body that volatile organic matter has been proved, have in addition genotoxicity and carcinogenecity, serious harm health arranged.Thereby to try every possible means VOCs concentration is dropped to minimum, to reduce until the harm of eliminating human body.For the improvement of volatile organic matter, people have research very early, and have developed some fruitful control technologys, but substantially all are the improvement at industrial higher concentration VOCs.And the concentration of VOCs is often lower in automobile, human settlements and the working environment, and absorption method is the efficient ways that usually adopts.Because the pore structure characteristic and the surface characteristic of NACF uniqueness make it have clear superiority aspect the absorption of low concentration gaseous substance.Carbon adsorption is irreplaceable aspect the recovery of high concentration organic vapor, and the purification aspect that is used for room air has certain defective, needs regeneration after saturated or changes.
Automobile and the indoor air cleaner of being sold on the market generally adopts the absorption of spun silk net or sponge to go up photocatalyst (TiO now
2), under the exciting of ultraviolet light, VOCs is resolved into CO
2And H
2O.But because spun silk net or sponge absorption property are relatively poor, cause reaction substrate VOCs concentration lower, influenced VOCs is resolved into CO
2And H
2O, it is not thorough to cause VOCs to decompose, and air cleaning is of low quality.China utility model ZL 200420070851.5 provides a kind of automobile air purifier, it is through the Filtration Adsorption of three kinds of different materials: at first by one or more layers electro static filtering net, secondly through the cellular activity carbon filtering device of one or many, again secondly through one or many aluminum honeycomb photocatalyst filter net, but this apparatus structure more complicated, cost are higher, the adsorption effect of VOCs is general, does not still reach ideal effect.
Summary of the invention
This utility model mainly is a technical problem relatively poor at the adsorption effect of the VOCs that exists in the prior art, that air cleaning efficient is not high, and a kind of air disinfection depurator is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of air disinfection depurator comprises filter screen, active carbon layer, uviol lamp and housing, it is characterized in that: described housing is a tubular, and the uviol lamp that is used for the exciting light catalyst is installed on the intracavity of housing; Active carbon layer is the Alveolate activated carbon capable layer that is coated with photocatalyst, is located at the upper and lower both sides of uviol lamp, and is fixed in the housing; Enclosure interior is provided with fan, and housing is provided with the air inlet of fan, and air inlet is other to be provided with filter screen, and a side relative with air inlet on the housing is provided with air outlet, the other filter screen that is provided with of air outlet.Fan is used to quicken air and flows, and makes air pass through the Alveolate activated carbon capable layer and flows at Che Nei or indoor circulation, make the Alveolate activated carbon capable layer as much as possible the VOCs in the absorbed air it is purified.Filter screen can be drainage screen or electrostatic filter, is used to remove dust in air, micronic dust and microorganism.The Alveolate activated carbon capable laminar surface is coated with photocatalyst, is photocatalyst-nano-TiO
2Carrier, VOCs absorption and catalytic decomposition place.Uviol lamp is used to activate the photocatalyst that is coated on the Alveolate activated carbon capable layer, and the harmful substance VOCs that is adsorbed on the Alveolate activated carbon capable layer is decomposed rapidly, simultaneously also can kill bacteria etc. microorganism.Uviol lamp of the present utility model and fan need connect power supply, generally can adopt direct current 12V or interchange through converting direct current 12V to.This utility model harmful substance VOCs absorption back is decomposed rapidly, thereby air cleaning efficient has obtained improving greatly owing to adopt surface-coated that the Alveolate activated carbon capable layer of photocatalyst is arranged.
This utility model is a complex carrier with the molding supporting mass active carbon with clear opening, adopt dip coating on complex carrier, to form nano titanium dioxide photocatalyst shell layer, prepare the active carbon-nano titanium dioxide photocatalysis purifying net that can be used for indoor air purification.Its purifying property is investigated the result to be shown, with power is the ultraviolet-sterilization light irradiation 3h of 6W, wavelength 254nm, its toluene purifying rate is 98. 8%, trichloroethylene (TCE) purifying rate is 99. 5%, the hydrogen sulfide purifying rate is 99. 6%, the ammonia decontamination rate is 96. 5%, and the purifying formaldehyde rate is 98. 5%, and the carbon monoxide purifying rate is 60. 1%.Show also that by the contrast experiment the compound air-purifying net of being developed has simple active carbon, simple light catalyst T iO
2, active carbon and the not available comprehensive advantages of purifying net such as titanium dioxide simply mixes, by the compound photocatalysis efficiency that improved, reach the purpose of active carbon in-situ regeneration simultaneously.
As prioritization scheme, described housing bottom is provided with and is trumpet-shaped collet, and collet is provided with several air inlets.Air inlet is used for the air inlet of whole device, and trumpet-shaped collet makes fan air inlet abundance, and trumpet-shaped collet when being positioned on the plane monolithic stability be difficult for rocking, be suitable for most being positioned in the automobile.
As prioritization scheme, described lower housing portion is provided with cable-through hole, and cable-through hole is used for the installation of power line.
As prioritization scheme, described air outlet is located at the top of housing, and produces convection current between the air inlet bottom being located at, and is beneficial to flowing of device inner air, can quicken the decomposition of harmful substance.
As prioritization scheme, the top of described housing is an arc.Make the device monnolithic case smoothly not have corner angle, be beneficial to the circulation of device inner air simultaneously.
As prioritization scheme, described Alveolate activated carbon capable layer has the square through hole of top-down 1mm * 1mm or 2mm * 2mm.Adopt the Alveolate activated carbon capable layer in square hole or other equilateral holes, the absorption of VOCs and decomposition efficiency are improved greatly, help air cleaning.
Therefore, this utility model adopts the Alveolate activated carbon capable that is coated with photocatalyst as the Filtration Adsorption medium, applies photocatalyst-nano-TiO with melten gel-gel method again
2, be equipped with fan and quicken air by cellular activated carbon and car internal recycle, make cellular activated carbon adsorb VOCs as much as possible, improve reaction substrate, under the exciting of ultraviolet light, VOCs is resolved into carbon dioxide and water, reach automobile and indoor clean-up effect.
