Description
Technical field
The present invention relates to automobile air purifying field, be specifically related to a kind of air purifier 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.
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.
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.
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 purifier.
CN104121633A discloses a kind of air purifier, comprising: air inlet; Gas outlet; Filter, filtering is from the pollutant the air that air inlet enters; Fan, by the air guiding gas outlet after metre filter; Air path switch, in a first state, makes the air after filtering discharge along the first air path from fan to gas outlet from gas outlet; In the second condition, by the air inlet side of the air directed toward filter after filtration; 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, all by filter or being used for of adsorbing purifies air, but the organic contamination in air, nitrogen oxide or oxysulfide be not by filtering or Adsorption, even if there is a few to adopt the air purifier of chemical catalysis, the pollutants in air of occluded air at normal temperatures, can not be reduced to ppm level in the short time by it.
Summary of the invention
The object of the invention is to propose a kind of air purifier preventing and treating haze, this air purifier can purify haze air, at room temperature, by organic pollution (aromatic pollution such as formaldehyde, methyl alcohol, benzene), sulfur and nitrogen oxides fast decoupled in air, the air of usage space effectively can be purified.
For reaching this object, the present invention by the following technical solutions:
A kind of air purifier preventing and treating haze, comprise housing and be arranged on the purifying part in housing, air purifier also comprises the movable side wall be fixedly connected with purifying part, purifying part also comprises the first screen pack and the second screen pack, second screen pack is arranged on the side of the first screen pack away from air inlet, first screen pack and the second screen pack are slidably disposed in chute, filter course is accompanied between described first screen pack and the second screen pack, described filter course is made up of the composition preventing and treating haze, described composition comprises following component
A) Al of 6%-20%
2o
3the Ce/Zr composite oxides of load, the mol ratio Ti:Ce:Zr of its each component is 1:(0.05-0.1): (0.05-0.1);
B) V of 3%-8%
