Description
Technical field
The present invention relates to airhandling equipment field, in particular to a kind of filter element, air filter and vapour
Automobile-used 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 can
Can be gas, solid or liquid suspension etc..Chinese large area occur haze be by air dust, sulfuric acid, nitric acid,
Serious contamination phenomenon caused by solid or liquid suspension that organic hydrocarbon compounds etc. are formed with the small water droplet in air.
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 next of air pollution
One of source.Wherein, the particulate matter of aerodynamic diameter (hereinafter referred to as diameter) less than or equal to 10 microns is known as inhalable
Grain object (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 in air
Middle substantial dwell time, and can enter in vivo with breathing, it accumulates in tracheae or lung, influences 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 gas 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 will be empty
Gas is filtered, and air suction device is used to draw air into air purifier.Also, one end setting of air purifier
Air inlet, other end setting gas outlet, filter device and air suction device are between air inlet and gas outlet.In this way,
Dirty air flows into air purifier, and after the filtering of filter device from air inlet, is 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, still can be with such as the pollutant of PM2.5 types
By general filter screen, cause air purification effect bad.If using the smaller sorbing material in aperture, filtering is greatly increased
The production cost of net, the production cost for leading to 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, and will be in air by automobile filter equipment
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's concern
Emphasis.
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 straight by vapour occupant
Sucking is connect, respiratory inflammation and scytitis are caused by human respiratory tract and skin contact, can also generate stimulation to eyes.First
Aldehyde can cause allergy, can also induce cancer.
