Description

Air filtration bag, air filter and automobile using filter
Technical field
The present invention relates to airhandling equipment field, in particular to a kind of air filtration bag, air filter and Automobile using filter.
Background technology
Air pollution is to be detrimental to health and the substance of surrounding enviroment is to the pollution caused by atmosphere.These substances May be gas, solid or liquid suspension etc..
Suspended matter is usually distinguished with the size of particle, and respirable suspended particulate in the middle can then influence health. The particulate matter of suspension in environmental science, refers in particular to suspend aerial solid particle or drop, is the main of air pollution One of source.Wherein, particulate matter of the aerodynamic diameter (hereinafter referred to as diameter) less than or equal to 10 microns is known as inhalable Particulate matter (PM10)；Particulate matter of the diameter less than or equal to 2.5 microns is known as fine particle (PM2.5).Particulate matter can be Substantial dwell time in air, and can accumulate in tracheae or lung with breathing into vivo, influence health.
Domestic environment is paid close attention to, therefore indoor decorating starts as a kind of fashion, but most of decorations at present All health is made containing harmful chemical, such as the escaping gases such as formaldehyde, ammonia, benzene homologues, these gases in material Into certain harm.
Metropolitan air quality each in recent years is unsatisfactory, and the polluter in air is more, and people are commonly using each Kind air cleaning facility carries out purified treatment to indoor air, wherein common air cleaning facility is air purifier.Often The air purifier seen is equipped with a sets filtering device and air suction device, and filter device is including filter screen etc., for by sky Gas is filtered, and air suction device is used to draw air into air purifier.Also, one end of air purifier is set Air inlet is put, the other end sets gas outlet, and filter device and air suction device are between air inlet and gas outlet.This Sample, dirty air flow into air purifier from air inlet, and after the filtering of filter device, are flowed out from gas outlet.
In general, the filter screen of filter device is made using materials such as activated carbons, to the granular dirt such as the dust in air Dye substance is adsorbed, and granular polluter is greatly decreased in the air after filter screen, so as to fulfill to air Purification.
But the granular substance in air is adsorbed using sorbing materials such as activated carbons, have to sorbing material Higher requirement, if sorbing material aperture is excessive, the smaller particle of some diameters such as the pollutant of PM2.5 types, still may be used To pass through general filter screen, cause air purification effect bad.If using the smaller sorbing material in aperture, greatly increase The production cost of filter screen, the production cost for causing air purifier are excessively high.
For automobile, to ensure the cleaning of air in a car compartment, existing automobile is generally all fitted with corresponding automobile Filter apparatus is filtered the air entered in automobile processing by automobile filter equipment, and will be in air Dust particles filter out.
For automobile filter equipment, the quality of quality directly affects the air quality quality of automotive interior, into And directly affect the health of driver；So for automobile, automobile filter equipment is always user pass The emphasis of note.
However, existing automobile filter equipment generally existing filters halfway defect；Particularly with toluene, formaldehyde And ammonia, existing filter apparatus is difficult to filter this out, and toluene, formaldehyde and ammonia can be directly by vapour vehicle occupants Member is directly sucked in, and triggers respiratory inflammation and scytitis by human respiratory tract and skin contact, can also generate thorn to eyes Swash.Formaldehyde can trigger allergy, can also induce cancer.
