Abstract
The utility model discloses an indoor air purifying device and belongs to the technical field of air purification. The device comprises a layer of filter cloth, two layers of activated carbon fiber felt, a layer of granular activated carbon flat layer and an ultraviolet lamp. The surface of the activated carbon fiber felt is provided with TiO2 with photo catalytic activity in deposition, the ultraviolet lamp is arranged between the two layers of activated carbon fiber felt, air flows in from the lower part of the device, and flows out from the upper part of the device after harmful substancesin the air is filtered, absorbed and degraded by photocatalysis. The indoor air purifying device provided by the utility model has simple structure and convenient operation and can remove the harmfulsubstances in the air sustainably and efficiently.
Description
Technical field
The utility model belongs to the air purifying process field, is specifically related to a kind of indoor air-purification device.
Background technology
People's most of the time is spent indoor, and IAQ has material impact to people's health.Because house decoration, electrical equipment are used and people's reasons such as activity, make indoor air pollutants concentration far above outdoor, indoor air purification more and more comes into one's own.Traditional air purifying process is fiber filter and charcoal absorption.Fiber filter can only be removed airborne suspension and accompanying bacterium thereof, can not remove volatile organic matter in the air, as formaldehyde, benzene series thing etc.Charcoal absorption can be removed organic matter, but along with the carrying out of purification process, absorption is tending towards saturated gradually and loses purification function.New technology such as plasma technique, ozone technologies etc. have been used for air cleaning, these two kinds of technology all need complex apparatus, and ozone itself and plasma produce some intermediate and be pernicious to people in purification process, thereby are difficult to apply in indoor air purification.TiO
2It is the new technology that developed recently gets up that photocatalysis is used for air cleaning, have equipment simply, advantages such as operation, non-secondary pollution at normal temperatures and pressures, be applicable to the indoor air purification processing, existing procucts appear on the market at present, but the not high shortcoming of ubiquity organic matter removal efficient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of new indoor air-purification device, is intended to continue the middle pollutant that purifies air efficiently.The utility model is achieved by following technical proposals:
This device is by one deck filter cloth, two-layer NACF felt, one deck granular activated carbon tiling layer and uviol lamp are formed, described filter cloth links to each other with the air inlet place, and its each composition is linked in sequence in such a way: filter cloth, NACF felt, uviol lamp, NACF felt and granular activated carbon tiling layer; Air NACF felt surface deposition has the TiO of photocatalytic activity
2, uviol lamp places between the two-layer NACF felt.
TiO
2With the mass ratio of NACF felt be 0.01-0.10, place 2-6 between the two-layer NACF felt and prop up uviol lamp, every power is 4-20W, the seed activity carbon layer is 1-3cm, air inlet is positioned at the device bottom, air outlet is positioned at top.
Compare with existing product, the advantage of the indoor air-purification device that the utility model provides shows:
1, can continue to remove efficiently airborne micro-content organism.The NACF felt is a sorbing material of new generation, and adsorption rate and adsorption capacity specific activity charcoal are much bigger, when air when the NACF felt, micro-content organism is by absorption fast and in addition enrichment, then by TiO in the air
2The photohole oxidation Decomposition on surface, NACF felt absorption property is recovered, and the air cleaning process can continue efficiently to carry out.
2, can thoroughly decompose harmful substances in air and can not produce new pollution.Harmful microorganism such as bacterium can not only be killed by ultraviolet ray in the air, and its corpse also can pass through TiO
2Photocatalysis and decomposing.Airborne organic matter can be by TiO
2The photohole on surface is decomposed into harmless water, carbon dioxide and other inorganic matter.The NACF felt is owing to be subjected to TiO
2The protection of film can not pulverized in purification process and taken out of by air.
3, airborne oxygen can produce small amount of ozone under action of ultraviolet ray; consume with airborne organic matter reaction if having little time; the set granular activated carbon layer in device top can and make it be decomposed into oxygen with its absorption, avoids cheating cleaned air passes and brings new pollution.
Description of drawings
Figure is the indoor air-purification device schematic diagram.
Among the figure: 1: filter cloth; 2: the NACF felt; 3: uviol lamp; 4: the NACF felt; 5: the granular activated carbon layer.
The specific embodiment
Indoor air-purification device provided by the utility model as shown in Figure 1.Device is by filter cloth 1, NACF felt 2,4, and uviol lamp 3, granular activated carbon layer 5 constitutes.NACF felt 2,4 surface depositions have the TiO of photocatalysis performance
2, TiO
2With the ratio of NACF felt quality be 0.01-0.10.Uviol lamp places between the NACF felt 2,4, and the uviol lamp nominal wave length is 254nm, and power is 4-30W, and number is that 2-6 props up.The seed activity carbon layer is 1-3cm.Air is entered by the device bottom, removes the activated fibre felt 2 of flowing through behind the suspension in the air through the filter cloth coarse filtration, and organic matter is adsorbed and diffuses to the surface near uviol lamp in the air, by TiO
2The photohole oxidation Decomposition on surface, residual organic substances are continued absorption and by the TiO on 4 surfaces on NACF felt 4
2Photocatalysis Decomposition.Bacterium, virus etc. are except that by ultraviolet direct irradiation and killing, its corpse can also be at TiO in the air
2The surface is decomposed by photocatalysis.Oxygen can produce small amount of ozone in the air under this installs the irradiation of used uviol lamp, and ozone can and consume with organic matter reaction in the air, and is if having little time with the organic matter reaction and stay in the cleaned air passes, then harmful.Because this device is provided with granular activated carbon layer 5, air is flowed through 5 o'clock wherein contained ozone by charcoal absorption and be broken down into oxygen.
In order to estimate air purification effect,, absorb airborne formaldehyde with distilled water, ammonia and bacterium with cleaned air passes with without the air that the purifies absorption plant of flowing through respectively.Adopt the concentration of metric measurement formaldehyde and ammonia; Adopt bacterial cultivation to measure bacterial population; Measure benzene in air content with gas chromatography.The control air mass flow is 10 cubic metres/hour, uses 4 8W uviol lamps, TiO
2With the mass ratio of NACF felt be 0.05, the seed activity carbon layer is 2cm, cleaned air passes is compared with unpurified air, bacterial population descends 95%, rate 99% under the formaldehyde, ammonia descends 98%, benzene descends 96%.
