Principle summary
As described above, in current air purifier（Air cleaning system）In, have especially for include in air
Evil gas componant, mainly carries out specific aim processing according to the material composition of pollutant.For example, for the improvement of haze pollution,
Mainly for the purified treatment of 2.5 particulate matter of PM；For the purified treatment of bacterium, virus, mainly killed using ultraviolet light, ozone
Poison processing；For gaseous contamination, mainly handled using activated carbon adsorption.
But in this existing air purification method, lack systematicness, because of actually indoor air pollutants
Constituent is extremely complex, and type category is many and diverse.The monotechnics of existing air pollution treatment are difficult to solve.For example, for
The removal of grain object, the prior art ultra-thin micro-particle difficult to realize for partial size less than 0.5/0.3 microns effectively remove, together
When, these ultra-thin micro-particles are the carrier and occurring source of some gaseous contaminations again.Therefore, it is either inhaled using such as active carbon
The reaction technology of attached technology or special material is only capable of having absorption and elimination effect to gaseous pollutant, but for particle
Object does not have detergent power, and caused final result is unsatisfactory.
In addition, the technical limitation of above-mentioned existing air cleaning scheme is obvious.For example, for bacterial virus in air
Killing processing, what is generallyd use is ultraviolet light or ozone sterilization technology.Ultraviolet light, ozone sterilization technology are highly developed, but have non-
The requirement of Chang Yange.If UV radiation technology for sterilization will realize basic bactericidal effect, the intensity, prolonged exposure to ultraviolet light
Time, use environment have to be clearly required very much, and in civilian air cleaning facility, irradiation time not can guarantee at all（It is protecting
Demonstrate,prove ultraviolet irradiation intensity it is enough under the premise of, to realize the various bacteriums of 100% killing, virus, the prolonged exposure time about 0.3~
Differ within 10 seconds, the medical institutions such as hospital are when carrying out disinfection by ultraviolet light, it is desirable that the prolonged exposure time be 30~60 minutes）, real
It when Most bacterial, virus on border in air pass through disinfection by ultraviolet light facility, is not killed, only accelerates thin
Bacterium, viral speed of mutation, increase the vitality of bacterium, virus, have encouraged the generation of infectious disease.
The defect of the above existing scheme has its source in the research lacked to pollutant genesis mechanism, causes the unilateral of technology
Property, even directionality mistake.All odor contamination objects are generally believed just such as to the improvement of finishing odor contamination object, in industry
It is to be caused by gaseous pollutant, all technologies are both for the processing of gaseous pollutant, such as activated carbon adsorption.But cause smell dirty
The primary pollution source of dye removes pure gaseous contamination beyond the region of objective existence, is more the ultra-thin micro-particle for loading these gaseous pollutants（Containing liquid
Drop）, and this part proportion is high, may be high by 80%, and active carbon does not have detergent power to particulate matter, causing can not be real
Existing clean-up effect.
For example, the utility model people has found after study for the formaldehyde pollution under house ornamentation environment, why new
Formaldehyde pollution is easy to produce in the case where finishing, significant portion is not because formaldehyde gas is directly volatilized from fitment material for family
Come, but there is the ultra-thin micro-particle being much easy to fall off in the fitment material for family due to newly installing, formaldehyde gas is adsorbed on these
On ultra-thin micro-particle.As these ultra-thin micro-particles are spread among air, the formaldehyde gas adsorbed on it also volatilizees
Out, to be polluted to room air.
Therefore, for the deficiency of above-mentioned existing air cleaning scheme, the utility model people of the application is proposed according to sky
The existence of gas pollutant carries out the targetedly matched air cleaning scheme of technology.That is, all dirts in air
Object is contaminated regardless of how many kind of type, and existing way is only six kinds following：Solid-state, liquid, gaseous state, solid-liquid mixing, solid gas mixing, gas
Liquid mixing.By being directed to the existence of pollutant, targetedly technology is formulated for the pollutant of every kind of existence and is solved
Scheme will significantly improve the effect of air cleaning.
Firstly, for solid-state, liquid, solid-liquid mixing, solid gas mixing, gas-liquid mixed pollutant, existing forms be all with
The form of ultra-thin micro-particle improves ionizing efficiency, adsorption efficiency by using Electrostatic Absorption technology to the maximum extent, comes real
Now to the removal of the pollutant of ultra-thin micro-particle form.Using air cleaning system according to the present utility model, may be implemented
It is less than the efficient removal of 0.5/0.3 microns of ultra-thin micro-particles to partial size, single cycle counting method efficiency is by industry traditional technology
30~50% be increased to 95% or more, this will be described in more detail below.
Secondly, the killing for bacterium, virus is handled, completely new theory and technology are also used.Mainly to based on air
It spreads germs, the research of Virus State.All viral partial sizes are both less than 0.3 micron, and viral existence, propagates needs at breeding
By ultra-thin micro-particle as carrier and nutrient source（Mainly human life activity is a large amount of as caused by breathing, body fluid discharge
Ultra-thin micro-particle containing organic matters such as protein, partial size is generally less than 0.5 micron, and namely densely populated place region is easy for this
The reason of communicable disease of influenza occurs）.It therefore, can be with as long as bacterium, virus are depended on for existence, the removal of the carrier propagated
Inhibit the propagation of bacterium, virus to greatest extent.Meanwhile bacterium, virus in ionization process, thus it is possible to vary bacterial virus it is micro-
Electric field environment causes protein denaturation, and bacterium, virus is made to lose activity, it is suppressed that bacterium, viral infectiousness.Therefore, for
The processing of bacterium, virus, can equally use Electrostatic Absorption technology.
Finally, for the processing of gaseous contamination, firstly, by the processing to ultra-thin micro-particle, it is especially small to partial size
In 0.5/0.3 microns of ultra-thin micro-particle（Containing liquid, compound state）, carrier and the generation of gas pollutant can be effectively removed
Source.In addition, can targetedly purify scheme further according to pollutant property, ingredient for pure gas pollutant to formulate.Example
Such as, in the embodiment of the utility model, it can realize that the degradation to pure gaseous pollutant is decomposed by the way of composite catalyzing degradation,
While decomposing polluted gas, recall degradation material is not consumed, so not needing to replace, no material consumption consumption.
System Summary on design
As described above, core is the superfine that realize less than 0.3 micron in the air cleaning scheme of the utility model
The efficient removal of particulate matter.
Here, it will be understood by those skilled in the art that the purification efficiency of electrostatic air cleaner is mainly by clarifier
Ionizing efficiency, adsorption efficiency determine.And the ionizing efficiency of clarifier, adsorption efficiency are further by discharge voltage, electric discharge
Electric current determines, that is, discharge voltage is higher, and efficiency is higher.But with the raising of discharge voltage, while it can also make electrostatic sky
The occurrence quantity of the secondary pollution ozone of gas purifier increases, and safety and durability are reduced.Therefore, in order to realize
High-efficient purification, the technological core of electrostatic air cleaner are operating voltage, operating current to be realized, purification efficiency, ozone hair
The final balance of raw amount, that is to say, that while realizing purification efficiency high as far as possible, the control of ozone occurrence quantity can connect
By in the range of（National standard 0.16mg/m3）, combine durability and the safety of product.
