Description

Air purifier

Technical field

The utility model relates to a kind of air purifier.

Background technology

Air is the necessity of human survival, and when quality is normal, the mankind are to this without any sensation, and a denier air goes wrong, and the mankind will experience the importance of air at once.On the earth, mankind's gathering occupies residence, particularly industrial area and urban area, comprises China, along with economic fast development, and the progress of medical technology, the liberalization that the mankind migrate, waits many reasons, has caused the explosive growth of population.In order to maintain the survival and development of a large amount of populations of the mankind, on on the basis of current scientific and technological level, the consumption fast rise of fossil organic matter (for example oil) and coal, causes the content of dust, heavy metal particles (as mercury, chromium, cadmium, lead, nickel etc.) and the microbe granular (as virus, germ, fungi etc.) of organic particle in earth surface (we live around) gas, volatile organic matter (as aromatic hydrocarbons, formaldehyde etc.), parcel inorganic matter (as sulfuric acid, nitric acid etc.) significantly to exceed standard.In addition, the concentration of various toxic and harmfuls (as nitrogen oxide, sulfur oxide etc.) increases simultaneously constantly, adds the generation of the earth's surface inversion layer that global warming causes, and often produces haze, has a strong impact on the mankind's health.

The purification of air is that the mankind resist one of air-polluting important means, although be dependent response, but, before the mankind's science and technology does not have to realize and can avoid the technological break-through of air pollution deposits yields completely, air cleaning will also can exist for a long time in the mankind's life, and can constantly be optimized and improve.

Air cleaning, the content that comprises two aspects.The one,, remove the suspended particulates such as airborne solid and liquid, comprise various microorganisms (such as germ, virus etc.); The 2nd, remove in air, contain to the poisonous and hazardous gas component of human body, as formaldehyde, benzene, sulfur oxide, nitrogen oxide etc.Although the mankind have designed and developed out a variety of air purifiers,, all there is larger deficiency in current air cleaning system.Known air cleaning system, according to their design and technology, is mainly divided into two kinds of the first generation and the second generations, all relies on filtering technique.First generation air purifier is more original, is by filtration system, to complete the filtering type clarifier of air cleaning completely, and filter comprises sorbing material and filter membrane.Their operation principle is: by sorbing material, adsorb toxic and harmful, utilize filter membrane to come the airborne microorganism of filtering and molecule (as pm2.5 particle).First generation air purifier is more original, there are two crucial weak points: the one, need to change frequently and filter and sorbing material, the 2nd,, because filtration system does not have efficient sterilizing function, cause the germ filtering out to assemble in filtration system, these germs that flock together can, by cutting one another's throats, only have the most powerful germ to survive, be actually cultivating superbug, people's health is existed to great potential danger.Second generation air cleaning system, has obvious improvement than the first generation.Second generation air purifier is used high-energy electric field (comprising intensive ultraviolet) to realize sterilizing virus killing function, or use inorganic peracid salt (as potassium permanganate, sodium dichromate etc.) to carry out sterilization and disinfection, then by the airborne solid of filter filtering and toxic and harmful.Under individual cases, also there is the method for the washing of being designed to carry out microorganism and the non-microorganism particle in wash-out and build-up of air, then the ultraviolet ray producing by high-energy electric field (or /) and ozone carry out kill virus germ, finally by filter filtering liquid without life particle.The high-energy electric field (as electrostatic field, ultraviolet ray etc.) of second generation air purifier, their effect is for the oxygen in activating air, make it to become highly reactive form of oxygen ion, these highly reactive form of oxygen ions hit and kill airborne microorganism, or the aerosol particle of destruction haze makes it to be polymerized to bulky grain.Due to these ultraviolet ray and electrostatic potential usually up to nearly 20,000 volts, in running, can cause a large amount of ionization of air molecule, thereby produce a large amount of free radicals and ozone.Free radical and ozone have been generally acknowledged conclusions to the harm of health.Although this design is compared with the improvement that has been designed with of first generation air purifier,, still must use filter to remove solid particle, do not break away from equally the filtering material that frequent replacement cost is high.In addition, because the design of the air purifier of the first generation and the second generation all must be used filtering material, these filtering materials can produce obstruction, therefore, they cannot carry out vast scale and amplify use, and large public place is because the quantity of particulate is countless, and filtering material may just stop up after several hours completely in start, up to now, outdoor public cannot be used known air clarifier to carry out air cleaning.For example, the gas on square, power plant dispatch from the factory gas, etc. purification.Current, power plant etc. are used the boiler of coal burning, and the general purification of tail gas is simple washing just, the harmful substances such as pm2.5 particle, formaldehyde, and major part is released in air.If adopt the material absorption such as membrane filtration or resin, price is extremely high, and disposal cost surpasses even the value of generating.

The air purifier of a kind of brand-new design of human needs, it is third generation air purifier, it need to overcome the deficiency of all first generation and second generation air purifier, can meet and remove in airborne various liquid-solid particles (comprising microorganism) and air the poisonous and hazardous gas of the mankind simultaneously.The air purifier of a new generation, otherwise use filtering material, do not use ultraviolet ray and high voltage electric field to avoid producing the secondary pollution harmful substances such as free radical or ozone, preferably also can not use clorox, potassium permanganate etc. can produce the disinfectant of secondary pollution.The utility model people is under the guidance of above-mentioned three basic demands, through constantly exploring, contrast, complete on the basis of thousands of kinds of designs, success utility model goes out third generation air purifier, overcome the deficiency of the first generation and second generation air purifier, realized and do not used high voltage electric field, but can realize efficient virus killing sterilizing; Do not use filter membrane or sorbing material, but can meet, remove all particles, can remove all the time the target of toxic and harmful again simultaneously.Third generation air purifier, owing to not needing to use filtering material to remove airborne particle, so this design can be both small size home appliance, it can be again main equipment, the clarifier that purifies for the large-scale air such as public place and commercial process.
