Description

A kind of air-conditioning filter cleaner preventing and treating haze
Technical field
The present invention relates to automobile air purifying field, be specifically related to a kind of air-conditioning filter cleaner preventing and treating haze.
Background technology
Haze weather is a kind of atmosphere pollution state, haze is the general statement to suspended particulate substance content overproof various in air, and especially PM2.5 (equivalent aerodynamic diameter is less than or equal to the particle of 2.5 microns) is considered to " arch-criminal " that cause haze weather.
The aerosol systems that mist is made up of the small water droplet be suspended in a large number in surface air or ice crystal.Come across autumn and winter season, be the product of ground layer water in air vapour condensation (or sublimating) more.The existence of mist can reduce air transparency, make visibility deterioration, if the horizontal visibility of object is reduced within 1000 meters, just the weather phenomenon of the condensation vapor be suspended in surface air (or sublimating) thing is called mist (Fog).
Haze, also claims the particle such as dust, sulfuric acid, nitric acid, organic hydrocarbon compounds in gray haze (smog) air that air also can be made muddy.The horizontal visibility of object is called mist or mist (Mist) in this phenomenon of 1000-10000 rice.Formed mist time atmospheric humidity should be saturated (when existing if any a large amount of nuclei of condensation, relative humidity not necessarily reach 100% just may occur saturated).Due to the mist scattering of aqueous water or ice crystal composition light and wavelength relationship not quite, thus mist seems to be creamy white or Bluish white and grey.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.
2013, " haze " became annual keyword.In the January of this year, 4 times haze process shrouds 30 provinces (district, city), and in Beijing, only having 5 days is not haze sky.Have report display, in 500 cities of Largest In China, only reach the air quality standard of world health organisation recommendations less than the city of 1%, meanwhile, polluting 10 the most serious cities in the world has 7 in China.
The harm that haze produces human body is as follows:
(1) on the impact of respiratory system
The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matter.The particulate that the mainly diameter be wherein harmful to health is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas etc., it directly can enter and stick in human respiratory tract and alveolar.Especially submicron particle can be deposited in upper and lower respiratory tract and alveolar respectively, causes the illness such as acute rhinitis and acute bronchitis.For chronic respiratory disease patients such as bronchial astehma, chronic bronchitis, obstructive emphysema and COPDs, haze weather can make state of an illness acute attack or acute exacerbation.If be in this environment for a long time also can bring out lung cancer.
(2) on the impact of cardiovascular system
Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, normal blood circulation can be hindered, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, miocardial infarction, heart failure etc. may be brought out, make chronic bronchitis occur cor pulmonale etc.
In addition, thick fog weather pressure ratio is lower, and people can produce a kind of sensation of agitation, and blood pressure can increase naturally to some extent.On the one hand often temperature is lower the greasy weather again, and some hypertension, patients with coronary heart disease go to suddenly cold outdoor from warm indoor, blood vessel expands with heat and contract with cold, and blood pressure also can be made to raise, cause the generation of apoplexy, myocardial infarction.The careful reply so heart and brain blood patient must take medicine on time.
(3) haze weather also can cause that surface layer is ultraviolet to be weakened, and make the increased activity of the infectiousness germ in air, infectious disease increases.
(4) child growth is unfavorable for.Because sunshine in greasy weather reduces, children's Ultraviolet radiation is not enough, and in body, vitamin D generates not enough, greatly reduces, serious meeting causes Infant Rickets, children growth slows down to the absorption of calcium.
(5) mental health is affected
Expert points out, there is impact in the lasting large greasy weather on the psychology of people and health, and say psychologically, the large greasy weather can cause oppressiveness, oppressive impression to people, can stimulate or aggravate the state of mental depression.In addition, due to the low pressure that greasy weather light is more weak and cause, some people can produce spiritual sluggishness, listless phenomenon in the greasy weather.
(6) fecundity is affected
There are some researches show, be exposed to the crowd in the air of high density pollution for a long time, the success rate of its sperm the time of fertilization in vitro may reduce.Researcher has also found the association between toxic air and male fecundity decline.
On November 5th, 2013, " climate change Green Book: reply climate change report (2013) " that the Chinese Academy of Social Sciences, China Meteorological Administration combine issue is pointed out, immediate and mid-term China haze weather is totally in increase trend.Wherein, mist number of days is in obviously reducing, and haze number of days obviously increases, and continuation haze process increases significantly.
At present, along with traffic congestion, people treat more and more for a long time in the various vehicles, and because motor space is narrow and small, its impact by haze is the hugest.Automobile, for the purification of air in car, is generally carry out adsorption filtration purification by air-conditioning filter cleaner.
CN104043298A discloses a kind of automobile air-conditioning filter, include housing, the top of described housing is provided with air inlet, the bottom of described housing is provided with air outlet, filament nonwoven filter cloth filter core is provided with in described housing, described filament nonwoven filter cloth filter core is formed by multilayer filament nonwoven filter cloth is stacked, it is characterized in that: be provided with layer of active carbon filter core below the inherent described filament nonwoven filter cloth filter core of described housing, described active carbon filter core comprises the active carbon be wrapped in non-woven fabrics.
The air-conditioning filter cleaner of prior art is all by filter or being used for of adsorbing purifies air, but nitrogen oxide in air or oxysulfide be not by filtering or Adsorption.
Summary of the invention
The object of the invention is to propose a kind of air-conditioning filter cleaner preventing and treating haze, this air-conditioning filter cleaner can purify haze air, and by the sulfur and nitrogen oxides fast decoupled in air, can effective purifying in-vehicle air.
For reaching this object, the present invention by the following technical solutions:
