Toxicity, irritation, carcinogenicity and special odor profiles, will affect skin and mucous membrane, acute lesion generated to human body.
Active carbon is black powder or bulk, graininess, cellular amorphous carbon, also there is the crystal of arranged regular
Carbon.In active carbon in addition to carbon, also include two class admixtures: one kind is chemically combined element, mainly oxygen and hydrogen, these
Element be due to not completely charing and remain in charcoal, or in activation process, external non-carbon element and activated carbon surface
Chemical bonding；Another kind of admixture is ash content, it is the inorganic part of active carbon, and ash content easily causes secondary dirt in activated carbon
Dye.Active carbon produces, in life due to being widely used in stronger adsorptivity.
The rapid development of present society economy, however air quality is but declining, for example, silk-screen welding resistance process is considered as
A more serious region of PCB industry TVOC damage ratio, it is considered that, normal, subcommercial indoor environment TVOC's is dense
Degree level is also unlikely to lead to the tumour and cancer of human body.But when TVOC concentration is 3.0-25mg/m3, stimulation can be generated
And discomfort, when with other factors synergy, human body is likely to occur headache；And when TVOC concentration is greater than 25mg/m3, except headache
Outside, in fact it could happen that other neurotoxic effects.Therefore, this problem of urgent need to resolve.

Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
It is a specific embodiment structural schematic diagram of air purifier of the invention with reference to Fig. 1, Fig. 1；Air purifier packet
Include shell 1, air outlet 3, air inlet 14, medium effeciency filter 4, the primary filter for filtering out particulate pollutant, exhaust fan 2,
At least one electrostatic dust-collecting device (5 as shown in figure 1 and 13) and at least one clean unit, air outlet 3, air inlet 14 are respectively provided with
On shell 1, specifically, the lower part of shell 1 is arranged in air inlet 14 and exhaust fan 2, for air to be pumped into shell 1,
The two sides of shell 1 are provided with air inlet 14, so that air more more rapidly enters air purifier；Air outlet 3 is arranged in shell
The top of body 1.Primary filter is mainly used for dust particle of the filter diameter at 5 μm or more, and primarily efficient filter implement body filters out grain
The diameter of son can be freely arranged, and in the present embodiment, primary filter uses primary efficient filter screen 15, as shown in Figure 1, can be just
The air inlet of effect filter screen 15 is connect with air inlet 14, i.e., primary efficient filter screen 15 corresponds to the inside that air inlet 1 is mounted on shell 1；
It can also be that the air outlet of primary efficient filter screen 15 is connect with air inlet 14, i.e. the corresponding air inlet 1 of primary efficient filter screen 15 is mounted on shell
The outside of body 1.And the inside of shell 1, this implementation is arranged in exhaust fan 2, medium effeciency filter 4, electrostatic dust-collecting device, clean unit
In example, by taking air purifier has 2 electrostatic dust-collecting devices, 1 clean unit as an example, specifically, clean unit includes at least
Layer of active carbon and at least one layer of ultraviolet lamp, to have 4 layers of active carbon (as shown in figure 16,8,10,12) and 3 layers in the present embodiment

Lamp, the surface of active carbon are covered with nanoscale TiO 2 particles, and active carbon is Alveolate activated carbon, the table of Alveolate activated carbon
Area is big, can increase the area coverage of TiO 2 particles, to improve air purification effect.As shown in Figure 1, two layers of active carbon
Between be provided with one layer of ultraviolet lamp, then ultraviolet lamp issue ultraviolet light can irradiate on the activated carbon.Similarly, electrostatic dust-collecting device
Surface be covered with nanoscale TiO 2 particles, and since active carbon has through-hole, be arranged in the two sides of clean unit
Two electrostatic dust-collecting devices can by ultraviolet lamp issue ultraviolet light be irradiated to.Specifically, electrostatic dust-collecting device includes electric discharge
Plate, insulated column and collecting plate, discharge electrode is relatively fixed in a manner of being separated by a certain distance with collecting plate insulated column, discharge electrode
Electric discharge is so that the grit in air is negatively charged, then positively charged collecting plate can adsorb the grit of electrification, realizes dust.Finally,
The outlet of medium effeciency filter 4 is connect with air outlet 3, and it is the particle dust of 1-5um and various that medium effeciency filter 4, which is used to filter out diameter,
Suspended matter in the present embodiment, is fallen since the long-term vibration of air purifier will lead to active carbon, medium air filtration is set
Device 4 filters out active carbon dust, guarantees in the air of air purifier output without dust.
With reference to Fig. 1, active carbon can adsorb the small organic molecule in air due to its superpower adsorption capacity, and purple
The ultraviolet light that outer lamp issues irradiates on the activated carbon, is when the Nano titanium dioxide ultramicron on active carbon receives wavelength
When 388nm ultraviolet light below irradiates, the TiO 2 particles of activated carbon surface excite generation electronics-sky due to absorbing luminous energy
Then cave pair, i.e. photo-generated carrier move to rapidly surface and activate the oxygen and moisture being adsorbed, generate the free hydroxy of activity
And active oxygen, the free hydroxy of activity and active oxygen can decomposing organic matter, so that it is finally changed into carbon dioxide and water, make to live
Property charcoal absorption air in volatile small molecule organic matter be decomposed, thus reduce remove TVOC pollution, air of the invention
Clarifier is a kind of smell photocatalysis purifier；Ultraviolet light can also effectively kill bacterium, virus and mould in air, reach point
Solve peculiar smell and volatile organic matter, the effect for killing bacterium, decomposition peculiar smell.Overcome that TVOC exists in the prior art is seriously polluted
The technical issues of.Using activated carbon adsorption TVOC, extend the time of light catalytic purifying, effectively improves the clean-up effect of TVOC.Separately
Outside, setting electrostatic dust-collecting device device can not only adsorb grit, moreover it is possible to further purify to the TVOC in air, effectively
Improve air purification effect.
It is carried over after the small organic molecule of activated carbon adsorption is broken down into carbon dioxide with air, active carbon can be again
The activity adsorbed continues to adsorb volatile small molecule organic matter, this design can reduce the dimension of smell photocatalysis purifier
Time and cost are protected, thus reach automatically cleaning, the purpose of round-the-clock purification.
In addition, active carbon can be uniformly immersed in nanometer titanium dioxide titanium solution for active carbon, keep solution equal
It is even to be distributed in the surface and hole of active carbon, it is then dried, is reinforced later using stainless steel frame assembling.And for electrostatic
For dust collect plant, the whole surface for spraying nanometer titanium dioxide titanium solution and solution being made to be distributed in electrostatic dust-collecting device can be passed through
On, finally dried again.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
