Abstract
The invention discloses an air purifier. The air purifier comprises a shell, a purifying part arranged in the shell and a movable side wall fixedly connected with the purifying part, the purifying part further comprises a first filtering net and a second filtering net, the second filtering net is arranged at one side, away from an air inlet, of the first filtering net, the first filtering net and the second filtering net are arranged in the sliding groove in a sliding mode, and a catalyst layer is sandwiched between the first filtering net and the second filtering net. After haze air passes through the air purifier, the content of PM2.5 particles, nitric oxide and sulfur oxide is reduced to a super-low level, air in a vehicle is effectively purified, and respiratory system health of indoor personnel is protected.
Description
Technical field
The present invention relates to automobile air purifying field, be specifically related to a kind of air purifier of preventing and treating haze.
Background technology
Haze weather is a kind of atmosphere pollution state, and haze is to various suspended particulate substance content overproofs in atmosphereGeneral statement, especially PM2.5 (aerodynamics equivalent diameter is less than or equal to the particle of 2.5 microns)Be considered to cause " arch-criminal " of haze weather.
Mist is by the aerosol systems that is suspended in a large number small water droplet in surface air or ice crystal and forms. ManyComing across autumn and winter season, is the ground layer water in air vapour product of (or sublimating) that condenses. The existence meeting of mistReduce air transparency, visibility is worsened, if the horizontal visibility of object is reduced in 1000 meters,Just the weather phenomenon that is suspended in condensation vapor (or sublimating) thing in surface air is called to mist (Fog).
Haze, also claims the grains such as the airborne dust of gray haze (smog), sulfuric acid, nitric acid, organic carbon hydrogen compoundSon also can make atmosphere muddiness. The horizontal visibility of object is called gently in this phenomenon of 1000-10000 riceMist or mist (Mist). While forming mist, atmospheric humidity should be saturated (while existence if any a large amount of nuclei of condensation, relativelyHumidity not necessarily reach 100% just may occur saturated). Due to the light of the mist scattering of aqueous water or ice crystal compositionLittle with wavelength relationship, thereby mist seems to be creamy white or Bluish white and grey. Sulfur dioxide, nitrogen oxidationThing and pellet are the chief components of haze.
2013, " haze " became annual keyword. In the January of this year, 4 times haze process shrouds 30Individual province (district, city), in Beijing, only having 5 days is not haze sky. There is report to show, 500 of Largest In ChinaIn individual city, only reach the air quality standard of world health organisation recommendations less than 1% city, same therewithTime, polluting in the world 10 the most serious cities has 7 in China.
The harm that haze produces human body is as follows:
(1) impact on respiratory system
The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matters. The master of being wherein harmful to healthIf the particulate that diameter is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate,Organic aerosol particle, fuel and automobile exhaust gas etc., it can directly enter and stick to human respiratory tract and lungIn bubble. Especially submicron particle can be deposited on respectively in upper and lower respiratory tract and alveolar, causes acute rhinitisWith illnesss such as acute bronchitis. For bronchial astehma, chronic bronchitis, obstructive emphysema and slowThe chronic respiratory disease patients such as property obstructive disease of lung, haze weather can make state of an illness acute attack or acuteIncrease the weight of. If also can bring out lung cancer in this environment for a long time.
(2) impact on cardiovascular system
Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, can hinder normal blood circulation, leadsCause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, may bring out angina pectoris, miocardial infarction, heart failureExhaust etc., 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 extentHigh. On the one hand often temperature is lower the greasy weather again, some hypertension, patients with coronary heart disease from warm indoor suddenlyGo to the outdoor of cold, blood vessel expands with heat and contract with cold, and also can make blood pressure raise, and causes sending out of apoplexy, myocardial infarctionRaw. 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 makes the work of airborne infectiousness germProperty strengthens, and infectious disease increases.
(4) be unfavorable for child growth. Because reduce sunshine in greasy weather, children's ultraviolet ray underexposure, dimension in bodyRaw plain D generates not enough, and the absorption of calcium is greatly reduced, and serious meeting causes Infant Rickets, children growthSlow down.
(5) affect mental health
Expert points out, continuing psychology and the health of large greasy weather on people has impact, says psychologically, greatly the greasy weatherCan cause oppressiveness, oppressive impression to people, can stimulate or aggravate the state of mental depression. In addition, due toThe weak and low pressure that causes of greasy weather light, it is slack, listless existing that some people can produce spirit in the greasy weatherResemble.
(6) affect fecundity
There are some researches show, long term exposure is in the airborne crowd of high density pollution, and its sperm is fertilized in vitroTime success rate may reduce. Between researcher has also found that poisonous air and male fecundity declineAssociation.
On November 5th, 2013, the Chinese Academy of Social Sciences, China Meteorological Administration combine issue " climate change is greenPi Shu: reply climate change report (2013) " point out, over nearly 50 years, Chinese haze weather is totally to increase andGesture. Wherein, mist number of days is obvious minimizing, 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, due to vapourCar narrow space, it is subject to the impact of haze the hugest. Automobile, for the purification of air in car, is generally logicalCross air purifier and carry out adsorption filtration purification.
CN104121633A discloses a kind of air purifier, comprising: air inlet; Gas outlet; Filter,The airborne pollutant that filtering enters from air inlet; Fan, the air guide after filter is filtered is given vent to angerMouthful; Air path switch, under the first state, make air after filtering along from fan to gas outlet theOne air path is discharged from gas outlet; Under the second state, by the air inlet of the air guide filter after filteringSide; Heater, by filter and air heat to make pollutant from filter desorption; And ultraviolet source,Send ultraviolet light to irradiate air, make to decompose from the pollutant of filter desorption.
The air purifier of prior art, is all by filtering or being used for of adsorbing purifies air, but airIn nitrogen oxide or oxysulfide but can not by filter or Adsorption.
