Description
Technical field
The present invention relates to a kind of air purifier.
Background technology
Air is the necessary of human survival, and when quality is normal, the mankind do not have any sensation to this, and asking occurs in a denier air
Topic, the mankind will experience the importance of air at once.Where on the earth, mankind's aggregation is lived, particularly industrial occupancy and city
Area, including including China, with economic fast development, the progress of Medical Technology, the liberalization that the mankind migrate wait many originals
Cause, result in the explosive growth of population.In order to maintain the survival and development of a large amount of populations of the mankind, in current scientific and technical water
On on the basis of flat, the consumption rapid increase of fossil Organic substance (such as oil) and coal, (we live to cause earth surface
Organic particle around) in gas, volatile organic matter (such as aromatic hydrocarbons, formaldehyde etc.), parcel inorganic matters (such as sulphuric acid, nitric acid etc.)
Dust, heavy metal particles (such as hydrargyrum, chromium, cadmium, lead, nickel etc.), and microbe granular (such as virus, pathogenic bacteria, funguses etc.) content
It is significantly exceeded.In addition, the concentration of various toxic and harmfuls (such as nitrogen oxide, sulfur oxide etc.) is continuously increased simultaneously, along with complete
Ball warms up the generation of caused earth's surface inversion layer, and Jing often produces haze, has a strong impact on the health of the mankind.
The purification of air is one of important means of mankind's antagonism air pollution, although be dependent response, but, in the mankind
Science and technology be not carried out avoiding completely the technological break-through that air pollutants produce before, purification of air is by the life in the mankind
In can also exist for a long time, and can be by continuous Optimal improvements.
Purification of air, comprising both sides content.One is, the particle such as solid and liquid in removal air, including
Various microorganisms (such as pathogenic bacteria, virus etc.)；Two be remove air in contain to the poisonous and hazardous gas component of human body,
Such as formaldehyde, benzene, sulfur oxide, nitrogen oxide etc..Although the mankind have designed and developed out a variety of air purifiers, current sky
All there is larger deficiency in gas cleaning system.Known air cleaning system, according to their design and technology, is broadly divided into
Two kinds of a generation and the second filial generation, all rely on filtering technique.First generation air purifier is more original, is to use filtration system completely
To complete the filtering type depurator of purification of air, defecator includes adsorbing material and filter membrane.Their operation principle is：It is logical
Adsorbing material absorption toxic and harmful is crossed, the microorganism in air and molecule (such as pm2.5 are filtered using filter membrane
Grain).First generation air purifier is more original, has two crucial weak points：One is to need frequently to change filtration and inhale
Enclosure material, two are, as filtration system does not have efficient sterilizing function, cause the pathogenic bacteria for filtering out to assemble in filtration system,
The pathogenic bacteria that these flock together can be by cutting one another's throats, and only most powerful pathogenic bacteria can survive, actually super in culture
, there is great potential danger to the health of people in level pathogenic bacteria.Second filial generation air cleaning system, is significantly improved than the first generation.
Second filial generation air purifier realizes sterilization function using high-energy electric field (including intensive ultraviolet), or uses inorganic peroxy
Hydrochlorate (such as potassium permanganate, sodium dichromate etc.) carrys out sterilization and disinfection, then filters solid in air and poisonous by defecator
Harmful gass.Under individual cases, also there is the microorganism that comes in eluting and build-up of air of method and non-microorganism for being designed as washing
Granule, the ultraviolet for then being produced by high-energy electric field (or /) and ozone killing viral pathogenic bacteria, finally by defecator
Filter in liquid without life granule.The high-energy electric field (such as electrostatic field, ultraviolet etc.) of second filial generation air purifier, they
Effect is the oxygen in activating air, makes highly reactive form of oxygen ion, and these highly reactive form of oxygen ions hit and kill in air
Microorganism, or destruction haze aerosol particle be allowed to be polymerized to bulky grain.Due to these ultraviolet and electrostatic potential it is usually high
A large amount of ionization of air molecule up to nearly 20,000 volts, in running, can be caused, so as to produce substantial amounts of free radical and ozone.
The harm of free radical and ozone to health has been generally acknowledged conclusion.Although this design setting compared with first generation air purifier
In respect of improvement, but, it is still necessary to using defecator remove solid particle, it is high also without frequent replacement cost is broken away from
Filtering material.Further, since the design of the air purifier of the first generation and the second filial generation must all use filtering material, these mistakes
Filter material material can produce blocking, therefore, they cannot carry out vast scale amplifies and uses, big public place due to microgranule quantity without
Number, filtering material may be just completely plugged after start a few houres, and so far, outdoor public cannot use known air
Depurator carries out purification of air.For example, on square gas, power plant dispatch from the factory gas, etc. purification.Currently, power plant etc. makes
With the boiler of coal burning, the general purification of tail gas is simply simple to wash, and the harmful substance such as pm2.5 granules, formaldehyde is most of
It is released in air.If adsorbed using the material such as membrane filtration or resin, price is extremely high, and processing cost even surpasses
Cross the value for generating electricity.
A kind of air purifier of brand-new design of human needs, i.e. third generation air purifier, it needs to overcome all
The deficiency of a generation and second filial generation air purifier, can meet while the solid granule of the various liquid removed in air (includes micro- life
Thing), and air in the poisonous and hazardous gas of the mankind.The air purifier of a new generation, otherwise filtering material is used, do not use purple
Outside line and high voltage electric field preferably can not also use hypochlorous acid to avoid producing the secondary pollution harmful substance such as free radical or ozone
Sodium, potassium permanganate etc. can produce the disinfectant of secondary pollution.The present inventor under the guidance of above three basic demand, through not
Disconnected exploration, contrast, complete thousands of kinds of designs on the basis of, successfully invent third generation air purifier, overcome the first generation
With the deficiency of second filial generation air purifier, realize, but can be achieved on efficient exterminating bacterium；Do not make
With filter membrane or adsorbing material, but can be to meet to remove all granules, while and the mesh of toxic and harmful can be removed all the time
Mark.Third generation air purifier, as the granule in air need not be removed using filtering material, so, this design was both
Can be small size home appliance, can be main equipment, net for large-scale airs such as public place and commercial processes again
The depurator of change.
